Installation of a chimney in a wooden house. How to lead the pipe from the furnace through the wall? How to make a chimney in a wooden wall of a house

The need to vent a chimney through a wall arises when installing heating equipment in an already built house. Competent selection of design, material, and trajectory of the chimney becomes a guarantee efficient heating premises. Also an important component flawless operation heating system is compliance with the installation algorithm established on the basis of practical experience and regulatory documents.

Functionality and design features

The optimal chimney length range is 5 – 10 meters. An indicator below the minimum value makes traction difficult, and a pipe longer than the designated 10 meters will provoke excessive combustion, increasing fuel consumption.

Since the smoothness of the internal planes of the chimney makes it possible to increase its durability due to a slight accumulation of soot, consumers are increasingly choosing a single-layer steel pipe, which successfully replaces brick counterparts. The installation of a chimney is simplified if a modern design of two nested inside one another is used. steel pipes with an insulating layer of stone wool between them.

This system has proven its practicality, since no negative condensation forms inside, and the outer surfaces receive slight heating.

When making a chimney outlet through a wall with its subsequent installation outside the house, it is necessary to consider the design of the protective box. It is advisable to make it brick, or use plasterboard, supplemented with fire-resistant thermal insulation.

Three-layer chimneys, the inner cylindrical pipe of which is made of ceramics, followed by a thermal insulation layer and outer blocks made of lightweight concrete, also show high performance.

Basic installation steps

When installing a smoke exhaust pipe through a wall, it is necessary to follow a certain sequence.

In the place of the wall where the pipe is planned to pass, there should be no internal communications and wires.
Markings are made on the wall and a hole of the required size is prepared.
The pipe is installed and fixed in the prepared hole. The passage in the wall is lined with fire-resistant insulating material, and the top is covered with a casing or plastered.
The chimney is connected to the heating device by joining a three-section elbow with a tee using a transition element.

Chimney passage in a frame house

The fastening elements intended for fixing the chimney to the wall have a pitch of 60–100 cm. Once the pipe has been brought to the design height, a cone-shaped element is attached to the top to protect against possible ingress of debris. In the gap between the wall and the chimney, a layer of mineral heat insulator is attached, for example, basalt wool. The top of the chimney is also insulated and sheathed with a casing made of fire-resistant and corrosion-resistant materials.

Features of working with wooden walls

Arranging a chimney in wooden house, it is necessary to take into account that its installation here has some features.

When making a passage through a wall, you need to additionally protect the pipe by covering it with fire-resistant bricks or asbestos. This measure is mandatory according to regulations fire safety, and it will also prevent wood fibers from drying out from heating at the point of contact with the chimney.

When starting installation, we select chimneys from a range of three-layer products, abandoning the single-layer steel chimney, which gets very hot. It is recommended to design a horizontal section of short length.

The vertical part, optimally, should be flat without turns. The chimney design must have dampers to regulate the intensity of combustion. If all requirements are met, the heating device will function efficiently and in a safe manner.

If wooden structure has a siding finish, then a gap to the chimney of ≥ 15 cm is provided. This is due to the fact that the temperature range regulated by manufacturers for this finishing material, ranges from minus 50 degrees to plus fifty degrees. The entire passage is protected by fireproof heat-insulating material.

When venting the chimney through the wall, it is recommended to orient it towards the gable side so as not to make additional holes in the roof. If heating device in the house is located in such a way that it is possible to remove the pipe only from the side where the roof slope is located, it may be necessary support post. The chimney is fixed to it using sliding fasteners.

For boilers with forced draft, installation can be carried out simply horizontal pipe, which should be brought out through a passage in the wall, similar to chimneys that also have a vertical part.

During the construction process, you can install a convenient chimney design in the wall, which is a shaft lined with brick. A pipe attached to the heating device is placed here. This scheme saves a lot of space.

If the installation of a universal chimney in the wall is carried out in the partition between rooms, then it becomes additional source light comfortable warmth. In order to correctly connect the heating equipment, it is necessary to make a sufficiently spacious passage in the shaft wall and install a pipe, joining its horizontal and vertical parts. Rock wool is usually used for insulation.

The upper cut of the pipe, coming out at a distance of one and a half meters, measured from the ridge, should rise above it by 0.5 meters. If the distance is one and a half meters or more, then the pipe is made at the level of the ridge.

When building a house, it is important to immediately think about how the internal systems, providing heating, drainage, smoke removal, etc. The smoke channel is laid simultaneously with the construction of walls and ceilings. Very often people think about where it will be when the house has already been built. In this case, lay the chimney through the wall. How to properly remove a chimney through a wall is described below.

Basic withdrawal rules

One of the main questions when building an exhaust system is how to properly organize the exhaust of the chimney through the wall.

When venting the chimney through the wall, it is very important to maintain an angle of 90 degrees. The next structural element is installed perpendicular to the previous one. I attached a condensate collector at the bottom, and all the main elements at the top.

Diagram of chimney outlet options

The resulting passage through the wall is carefully insulated. Be sure to seal all joints (where various elements are fastened) with clamps.

Another important nuance– correct and reliable fastening of the chimney to the wall. At one time, they promptly suggested to me that it was necessary to fasten at approximately equal intervals. In my opinion, the most suitable distance for installing fasteners is 50-60 cm.

It is imperative to insulate the pipe from the wall. The best option – high quality and affordable – is basalt fiber. The final stage - the “neck” of the chimney is covered with a special cap.

Installation through a wooden wall

If you have a wooden house or bathhouse, you need to know exactly how to remove the chimney through the wall. The main problem is the issue of security. But if you approach the matter correctly, then even a chimney in a bathhouse through a wall, where there will be a constant difference in high temperatures, will serve reliably and for a long time.

I'll tell you about a few main rules. The pipe that stretches across the entire passage must be covered with a material that is resistant to high temperatures. This will help avoid deformation of the wood - and also avoid the risk of fire. I advise you to give preference to a vertical system (such as a potbelly stove, which is often used for heating garages).

The chimney is attached to the wall of a wooden house at a distance of 1 meter from each other. For wooden buildings I advise you to choose long, straight pipes: the absence of joints makes the structure stronger, plus it will be much easier to attach to the wall.

Advantages of an external chimney

The use of such a system will provide increased efficiency, and the light weight of the structure will help avoid installation problems. Although there is an opinion that a chimney in the wall of a house does not look aesthetically pleasing. But it ensures fire safety!

A clear advantage is that there is no need to make a passage through a wall, ceiling or roof. There is no need to further strengthen the foundation. In addition, a minimum of soot is deposited on the walls: and it is quite possible to remove it yourself.

Materials and tools for installation

If earlier chimneys were made of brick, now they choose, for example, a sandwich design. The advantages of this design are as follows:

Long service life (if you use stainless steel materials).
The overall weight is light, which simplifies installation.
And the third point, which is important for me personally: aesthetic appeal.

To install a sandwich chimney, the most important thing is to choose good materials. The integrity of the entire structure depends on how durable and resistant to high temperatures each pipe is. I recommend choosing those made from fire-resistant steel and galvanized metal.

In addition, we will need clamps, plugs, sealant (necessarily fire-resistant!), couplings, fastening elements. You will also need adapters, tees, and an elbow that will allow you to change the direction of the structure.

Main design elements

I propose to consider the main design elements using the example of a sandwich chimney:

One of the most important elements– pipes. Tees are also needed - they help to branch the smoke channel and connect the chimney directly to the firebox of the heating device.
Elbow - will be needed to make the necessary bend (bends at 45 and 90 degrees are most often used).

The support console - in fact, the entire structure will be supported on it and is attached to the wall or floor. Plus the clamps are needed for fastening and fixing to the wall.
Inspection tee - for cleaning pipes from soot.
Condensate collector.
The mouth is the final element of the structure.

Installation instructions

The starting point should be the heating device itself. Simply put, they begin to install the structure from the bottom up - from the fireplace. First, the pipe is connected to the boiler pipe and secured with a plug.

Carefully insert the inner pipes into each other. Then we put on the outer part.
Strengthen the tees with support brackets. All joints are strengthened with clamps.
I recommend installing a condensate collector on the lower part of the structure to prevent precipitation from getting inside the pipes.
Sealed couplings are installed solely at will - you can do without them. They are needed if the system operates under high pressure.
When the system is almost assembled, you can carefully treat the pipes with a protective sealant.

If you doubt that it will be difficult to install the system yourself, it is better to immediately seek help. It’s always easier to immediately learn how to do it right than to have to do it all over again later, taking into account the mistakes made.

How to properly remove a chimney through a wall? When building a house, it is important to immediately think about how the internal systems will be installed to provide heating, drainage, smoke exhaust, etc. Smoke

Many questions and problems arise at the moment when it is necessary to make a passage chimney through the wall.

When designing this stage of work, one should take into account big number factors, including:

Wall structure,
Materials used,
Pipe exit location
Diameter of the chimney opening.

Diagram of the pipe exit from the furnace through the wall

Before figuring out how to remove a chimney pipe through a wooden or concrete wall, you should carefully study the diagram of the pipe exit from the stove.

Below is a diagram of the output of a double-walled chimney through the wall:

Options for venting the chimney through the wall

What chimneys can be routed through the wall?

As building material usually black steel or alloy is used of stainless steel, since this metal is most protected from the destructive effects of hazardous factors and smoke components.

Calculations and installation rules

Installation rules imply careful consideration of all stages of future work:

You should make sure that the pipe itself will not come into contact with any flammable materials, which, under the influence of high temperatures, may begin to smolder and release toxic fumes.
When installing the system directly externally, it is necessary to remember the deflection angles, which will act as active guides for smoke removal. The chimney pipe should not be located parallel to the wall of the house, since in this case smoke stasis will occur - it simply will not be removed from the system.
Special tees must be installed in the lower and side parts of the pipe, which will be used as a place to install mechanisms for condensate drainage. If this step is not completed, then moisture when lighting a fireplace or stove will simply enter the firebox and extinguish the flame. All this will significantly complicate the kindling process!
The upper part of the pipe should rise above the edge of the roof to ensure that smoke and soot are blown away in an area of more rarefied air. Typically, such zones are formed at a distance of 15-25 cm from the roof sheet.

How to install a chimney?

The chimney installation process is divided into several main stages, which consist of:

Preparatory work
Installation of fastening elements,
The actual installation of the chimney.

General stages of work:

You need to drill a hole in the wall through which the chimney itself will exit, using a special tool. Modern models have adjustable nozzles and active cooling systems to prevent the appearance of cracks on the surface of the facade.

Passage through concrete/brick wall. Concrete and brick walls are the most comfortable material, which does not require additional processing. It is recommended to additionally putty the place where the hole was created in order to eliminate the possibility of rapid degradation of the wall of the room.
Passage through a wooden wall

When working with wooden surfaces, care must be taken to protect against overheating. Hot air passes through the pipe, which can cause materials to unintentionally ignite.

Ceramic mixtures, heat-resistant insulating materials and even glass wool are often used as insulating materials. You should not skimp on thermal insulation, as the consequences can be very sad!

The need to vent a chimney through a wall arises when installing heating equipment in an already built house. Proper selection of the design, material, and trajectory of the chimney becomes a guarantee of effective heating of the premises. Also, an important component of the flawless operation of the heating system is compliance with the installation algorithm established on the basis of practical experience and regulatory documents.

Functionality and design features

Chimney through the wall to the street

Since the smoothness of the internal planes of the chimney makes it possible to increase its durability due to a slight accumulation of soot, consumers are increasingly choosing a single-layer steel pipe, which successfully replaces brick counterparts. The installation of a chimney is simplified if its modern design is used: two steel pipes nested one inside the other with an insulating layer of stone wool between them.

This system has proven its practicality, since no negative condensation forms inside, and the outer surfaces receive slight heating.

The pipe is installed and fixed in the prepared hole. The passage in the wall is lined with fire-resistant insulating material, and the top is covered with a casing or plastered.
The chimney is connected to the heating device by joining a three-section elbow with a tee using a transition element.

Chimney tee and its dimensions

In order to change the vector of the chimney to a vertical direction after leaving the wall, take a tee equipped with a cleaning cup, which is fixed with a bracket. Experts do not recommend making a horizontal section installed in a wall passage over one meter, as this can reduce traction. If conditions do not allow this requirement to be met, the total length of the chimney is increased to compensate.
It must be taken into account that a pipe that has a passage through a wall can be directed at an angle, the angle of which is determined technical characteristics heating device. This circumstance must be given attention so as not to degrade the performance of the equipment.
Then the installation of the remaining part of the pipe continues, running vertically up along the wall. To keep it securely, there is a stand at the bottom on which the chimney rests.

Installation of chimney fasteners

The fastening elements intended for fixing the chimney to the wall have a pitch of 60–100 cm. Once the pipe has been brought to the design height, a cone-shaped element is attached to the top to protect against possible ingress of debris. In the gap between the wall and the chimney, a layer of mineral heat insulator, for example, basalt wool, is attached. The top of the chimney is also insulated and sheathed with a casing made of fire-resistant and corrosion-resistant materials.

When making a passage through a wall, you need to additionally protect the pipe by covering it with fire-resistant bricks or asbestos. This measure is mandatory according to fire safety standards, and it will also prevent wood fibers from drying out from heating at the point of contact with the chimney.

Chimney passage through a wooden wall

If a wooden building is finished with siding, then a gap to the chimney of ≥ 15 cm is provided. This is due to the fact that the temperature range regulated by manufacturers for this finishing material ranges from minus 50 degrees to plus fifty degrees. The entire passage is protected by fire-resistant heat-insulating material.

When venting the chimney through the wall, it is recommended to orient it towards the gable side so as not to make additional holes in the roof. If the heating device in the house is located in such a way that the pipe can only be removed from the side where the roof slope is located, then a support stand may be needed. The chimney is fixed to it using sliding fasteners.

Connecting the roof to a round pipe

If the roof overhang is > 40 cm, a rack may not be needed, since the chimney passes through a hole cut in the roof. It's done here additional fixation pipes. It must be taken into account that there should be no joints in this place individual elements chimney. Above the hole it is necessary to equip devices that retain snow. They will protect the chimney from excessive pressure from snow layers that can cause damage.

Vertical and horizontal chimneys

For boilers with forced draft, it is possible to install simply a horizontal pipe, which should be routed through a passage in the wall in the same way as chimneys that also have a vertical part.

If the installation of a universal chimney in the wall is carried out in the partition between rooms, then it becomes an additional source of light, comfortable heat. In order to correctly connect the heating equipment, it is necessary to make a sufficiently spacious passage in the shaft wall and install a pipe, joining its horizontal and vertical parts. Rock wool is usually used for insulation.

Installation diagram of a chimney through a wall
How to install a chimney through a wall - functionality, design features, main installation stages, features of working with wooden walls, recommendations from specialists.

There was also a simpler option - from metal pipe, but additional difficulties arose with it. And how good it is now that sandwich pipes for chimneys have appeared.

What are the advantages

The advantages of sandwich pipes include:

light weight,
versatility of use, which allows them to be used with any heating devices,
attractive appearance,
durability and resistance to destructive factors,
reliability in terms of no risk of fire,
thanks to the smoothness inner surface pipes can rarely be cleaned of soot,
ease of assembly,
quickly cools the smoke inside the chimney,
Suitable for both indoor and outdoor use.

It is clear that the stainless steel from which the pipe is made makes the price quite high, and this is a relative disadvantage. A incorrect installation Over time, it can cause loss of integrity of the structure. But if the first one pays off with a long service life, then the second one depends only on who will do the installation.

It is important to know

Before starting the installation, you should familiarize yourself with some subtleties. For example, it is important to know what big square the structure will be held indoors, the less heat loss there will be. When creating a detailed diagram, take into account the fact that smooth horizontal sections should be up to one meter. Please note that contact of the system with any communications, such as gas and electricity, is unacceptable. And if on the way to place the chimney there are wooden parts, then the pipe must be moved away from them using special steel brackets. The distance between fastenings should not exceed one meter.

Also include in the plan a part of a collapsible pipe or insert with a door through which inspection and cleaning of soot will be possible. Of course, installing a sandwich chimney is a serious and responsible matter, so if you decide to do it without specialists, then understand the degree of responsibility and strictly follow the step-by-step instructions.

In the finished building, a chimney is installed through a wall made of sandwich pipes. To do this, measures are taken to protect the wall from the high temperature of the chimney. It’s good if the house is new and it is possible to install the system indoors. But in a wooden house without insulating materials not enough. And it doesn’t matter what you choose for this purpose: mineral wool or asbestos, but you will have to do it. These are the fire safety standards for log houses.

Already at the stage of purchasing pipes, you should have a diagram and calculations on hand. A short chimney will not have draft, and often smoke and soot will return indoors, and if it is too long, this will speed up the process of fuel combustion and heat will escape into the atmosphere. The optimal length of the system is considered to be in the range from 5 to 10 meters. In addition to the chimney itself, you will need various tees, pipes, elbows and fastenings.

It's clear that perfect option- this is the passage of a pipe through a roof or wall, and it does not matter whether it is taken into account by the building design. This guarantees your safety. But if it doesn’t work out, then we look for an area on the wall where there are no other technological designs. Experts advise to retreat at least 40 cm from any communication, and if this is not possible, then provide additional insulation.

Different walls have their own installation secrets

If you have walls made of logs, then pre-drill required holes, larger in diameter than the pipe itself. Round shape A special drill will help create holes. And now, in order:

First method: you will need several heat-insulated pipes of a larger diameter than the chimney, inserted alternately into each other,
The second option: we run the chimney through the wall, laying out the space between them with high-quality thermal insulation.

Passing through a brick or twin block wall is done like this. First, markings are made taking into account the appearance of cracks from the holes made. In order to avoid this kind of problem, place a special metal carcass. The free space near the pipe must be filled with fireproof material and shields must be installed to cover the passage. The main difficulty is just getting through the wall, and then assembling the structure is quite simple. Have you collected it? We fix it on the wall.

It is clear that when they mount experienced craftsmen, then there is no doubt about safety and reliability, but if you decide to do it yourself, then just remember the responsibility entrusted to you for the lives of those who will live in this house.

Step-by-step installation of a chimney made of sandwich pipes through a wall
In the foreseeable past, no one would have thought that installing chimneys would be within the capabilities of everyone. And it’s clear why this is so. Previously, only a stove maker knew how to properly create a brick the desired shape and design size. Such knowledgeable people were very much appreciated.

Chimney - an important part proper arrangement stove, solid fuel or gas boiler. The efficiency of the heating device and the fire safety of the heating system depend on its correct design and installation.

Chimneys in a house, especially a wooden one, or in a bathhouse must be made of various fire-resistant materials. Brick chimneys They are resistant to high temperatures, durable and aesthetically pleasing, but at the same time the porous and heterogeneous structure of the brick promotes the accumulation of moisture and the deposition of combustion products - soot and soot. As a result, the lumen of the chimney becomes overgrown, draft deteriorates, and operation of the stove becomes unsafe. It is especially undesirable to use brick chimneys in systems for removing smoke from solid fuel, including pellet, boilers with closed camera combustion.

Ferrous metal pipes are not recommended for use in wooden houses and bathhouses, as well as when installing a gas or solid fuel boiler: they become very hot and quickly burn out, which can lead to a fire. Sometimes chimneys made from such pipes are installed in brick garages and other utility rooms, but even there they are ineffective, as they are susceptible to corrosion and condensation.

Most good decision- insulated sandwich chimneys made of stainless steel and ceramics. The round cross-section of the pipes facilitates the passage of smoke and provides good draft. Less soot deposits on a smooth inner surface. Due to insulation, the formation of condensation is eliminated. Thanks to modular system Their installation is easy to do with your own hands. Structurally, sandwich chimneys made of stainless steel and ceramics are somewhat different.

Ceramic sandwich chimney is a system of modules, each of which consists of an internal ceramic pipe element and a hollow foam block. For thermal insulation they are separated by a layer basalt insulation. The modules are supplied disassembled and assembled on site using special glue and sealant. To install a ceramic chimney, a foundation is required due to their significant weight.

Stainless steel sandwich chimneys sold in the form of ready-made modules. They are two pipes different diameters, nested one inside the other, and separated by a layer of insulation. The inner pipe is made of stainless steel, the outer pipe can be made of either stainless steel or galvanized sheet. They assemble much faster than ceramic ones. In addition, due to its light weight, a stainless steel chimney does not require a foundation.

Ceramic chimneys are superior to all others in fire resistance; they can withstand temperatures up to 1200 degrees Celsius for a long time; some models are equipped with ventilation systems. The service life of such chimneys is at least 50 years. But the price of ceramic chimneys is high, so their installation is advisable only in residential buildings, cottages and other permanent buildings.

General installation rules

To ensure good draft, the height of the chimney from the grate of the heating unit must be at least 5 meters.
The chimney located at the ridge should rise 0.5 m above it; in other cases, its height is determined according to the diagram below.

It is necessary to take into account standing nearby with a house or bathhouse building, the chimney outlet should be 1.5 m higher than their roof.
If, as a result of calculations, the height of the chimney above the roof is more than 1.5 m, it is necessary to provide in advance for attaching it with guy wires to rigid structural elements.
If the roof material is flammable - ondulin, roofing felt, soft roof, then the top of the chimney must be equipped with a spark arrester - a special module with a 5x5 mm mesh.
The smoke channel cannot be narrowed; for example, for a stove with a smoke pipe of 120 mm, modules with an internal diameter of 110 mm cannot be installed. Widening is permitted, but special adapters must be used.
The length of horizontal sections should not exceed 1 m. In case vertical pipe located at a greater distance from the heating device, it is necessary to use bends at 45 degrees.
Bends, tees and other adapters of sandwich chimneys must be unloaded - installed so that they do not bear the weight of the higher structure. Support platforms are used for this.
All module joints must be accessible for inspection. They should not be placed in areas of ceilings. To meet this requirement, it is necessary to select the length of the straight sections of the chimney.

Correct assembly sequence

First, connect the outlet pipe of the boiler or stove to the lower element of the chimney - a single-layer uninsulated pipe. It can consist of several modules and be vertical, horizontal or bent by 45 or 90 degrees.
To switch to an insulated pipe, use an adapter. It is put on an uninsulated pipe, coating the joint with a special sealant that can withstand temperatures up to 1300 degrees Celsius.

Further assembly is done with your own hands from insulated elements. They are inserted into each other so that the upper part fits over the lower part. The top can be determined by the edge of the pipe - it is wavy, which makes joining easier. With this installation, the internal channel is connected “along the smoke”, that is, the direction of the joints is located so as not to interfere with the smoke flows inside. All elements are connected with heat-resistant sealant.

According to the place of installation, smoke removal systems are divided into internal ones, passing through interfloor ceilings both roof and external, located near the outer wall of the building. In this case, the chimney outlet is made through the wall of the house or bathhouse.

The part passing through heated rooms may be made of single stainless pipe- its surface becomes very hot when fuel burns and additionally gives off heat. When passing through an unheated attic in a house or bathhouse or outside, the chimney requires mandatory insulation, so sandwich modules are used for this part of it.
A direct chimney can rest directly on a heating device - a stove, a pellet boiler. If there are branches or bends, it is necessary to install support platforms at the floor level, at least every 5 meters.

At outdoor installation the system is secured using wall fastenings - brackets with clamps. They are sold complete with chimneys. The lower part of the chimney is supported by a cantilever bracket.
The pipe is equipped with cleaning facilities in places convenient for access. They are a tee with a plug placed on the outlet. If necessary, remove the plug and inspect and clean the smoke channel from soot. A plug with a condensate receiver is installed at the bottom of the pipe.

The greatest attention should be paid to passages through walls, ceilings and roofs. For them, special modules are used: “passage through the ceiling” and “passage through the roof”. The top of the pipe is equipped with an umbrella to ensure fire safety, improve draft and ventilation.

In a wooden house

Before installing a smoke removal system with your own hands, you need to study fire safety requirements to chimneys installed in a wooden house.

the distance from the uninsulated chimney to any combustible surfaces must be at least 25 cm horizontally and 80 cm vertically;
passages of the chimney through the roofs must be carried out using passage units - metal boxes filled with heat-insulating material, usually basalt mats;
in case of connecting several smoke channels into one, it is advisable to place vertical chimney in a separate box from non-flammable material, for example, foam concrete.

An inspection of all sections of a stainless steel chimney in a wooden house must be carried out at least twice a year! If external damage, discoloration of steel, or rust is detected, it is necessary to ensure the integrity of the inner pipe- it could burn out!

WITH simple designs smokehouses for cold smoking and methods of their manufacture at home and hiking conditions can I meet you?
All stages of manufacturing a smoke generator for cold smoking are described in detail in the following article:

In the bath

Bathhouse is a place of increased fire danger. The heating of wooden surfaces in a bath reaches 90-100 degrees, and the temperature at which wood begins to char is 120-150 degrees with prolonged exposure. Wooden elements located near the chimney heat up the most. Therefore, fire safety distances must be strictly observed.

The sequence of installation of passages through the wall and ceiling in the bathhouse, which can also be used in the house, is shown in the video.

Since the largest part of heat loss in wooden bath occurs through ceilings, the pipe is often routed through walls.

Chimney for buleryan

Connecting a buleryan to a chimney with your own hands is generally no different from other types of heating devices, but it is necessary to take into account the peculiarities of the combustion mode in this type of stove.

Thanks to efficient afterburning flue gases their temperature at the furnace outlet does not exceed 200 degrees. As it moves through the pipe, it decreases even more, the pipe warms up weakly, which is why condensation can form on the walls of the pipe. When soot is deposited on wet walls, carbonic acid is formed, which negatively affects materials such as brick, ferrous metal, and asbestos.

recommended height - from 3 to 4 meters;
the length of the horizontal section is strictly no more than 1 meter;
the material of the internal surface must be resistant to acid - sandwich chimneys made of stainless steel or ceramics;
It is recommended to insulate all sections of the chimney except the exit from the buleryan;
The chimney must be equipped with a condensate collector and cleaning.

Effective operation of the buleryan is only possible with access to the firebox fresh air, therefore, it is advisable to use a modular ceramic chimney with channels for ventilation; its installation, thanks to the prefabricated modular design, can be done with your own hands.

For solid fuel boilers

Regular solid fuel boilers Those burning coal, wood or having a pellet burner are characterized by high flue gas temperatures. Pyrolysis boilers with the regime long burning burn the combustion products contained in the smoke more efficiently, so the output is more low temperature, and, like buleryan, are prone to increased condensation.

boiler type;
location and diameter of the smoke pipe;
flue gas temperature;
recommended chimney height to ensure good draft;
the need for additional ventilation.

You should also inspect the boiler design and evaluate the difficulty of cleaning the smoke pipe. If access to it from inside the boiler is difficult, it is necessary to provide an inspection tee in the immediate vicinity of the boiler outlet.

If the pellet boiler is equipped with a closed combustion chamber, it would be more advisable to install a coaxial chimney with a ventilation system.

For gas boilers

Gas boilers belong to heating units with a closed combustion chamber, so for them the most effective installation would be coaxial chimney. It is a structure consisting of two pipes of different diameters, with the smaller pipe inserted into the larger one and secured in it with jumpers.

By inner contour The coaxial pipe removes flue gases from the combustion chamber of the gas boiler to the street, and air moves in the opposite direction through the gap between the chimney pipes. It enters the combustion chamber and supports combustion, without taking air from the room where the gas boiler is installed, which significantly improves the microclimate in the house and eliminates the installation of an additional ventilation system.

Air is a good heat insulator, so the outer surface of the coaxial chimney heats up slightly. At the same time, in ventilation duct the air is heated and enters the combustion chamber of the gas boiler already warm, which increases the efficiency of the boiler.

Installation of a coaxial chimney for a gas boiler is most often done through a wall, less often through ceilings and a roof, as this increases costs. Safe distances from building structures when installing a coaxial chimney are shown in the picture.

Video about installing a coaxial chimney

When installing a conventional sandwich chimney on a gas boiler, you need to make an additional system yourself supply ventilation, since the oxygen necessary for combustion will be absorbed from the air.

Correct installation of a chimney is the key to long and safe operation of the heating system both in the house and in the bathhouse. It is possible to do it yourself, but if you have even the slightest doubt about your abilities, it is better to entrust this task to professionals. They will make calculations and help you choose best view chimney, a gas exhaust and ventilation system will be installed, and the owner of the house will only have to independently inspect and clean the chimney.

Of all types of boiler equipment, perhaps only electric ones do not require a device for removing fuel combustion products - chimneys. A man, based on many years of construction experience, learned to remove smoke using various shapes structures that can be made from natural stone, brick, sheet metal.

Sandwich pipe for chimney. Why she?

Recently, multilayer sandwich chimneys have become widespread. Their design is extremely simple. A heat-insulating material is applied to a pipe made of stainless steel, usually this mineral wool, made of basalt. This, in turn, is covered with another pipe, which can be made of corrosion-resistant steel or galvanized sheet. There are locks at the end of the pipes, which allow the installation of a chimney from sandwich pipes through walls or roofs without any particular difficulties.

Thus, the homeowner, how to install a chimney, can easily assemble a gas exhaust system on his own, without resorting to the expensive services of third-party specialists. But, at the same time, he must know how to properly install a chimney and some other rules that will protect his home from fire in the future due to improper assembly or operation of this structure.

Features of the use of steel

Fuel combustion products are highly saturated with chemically aggressive substances. Temperature differences and the presence of moisture inside the sandwich pipe create the prerequisites for the activation of corrosion processes. Corrosion processes are minimized by using stainless steel. But, in fairness, it should be noted that the use of this rather expensive material does not eliminate all the problems associated with the use of metal in chimney structures.

A stainless steel sandwich guarantees rapid cooling of combustion waste, especially in those areas of the chimney located on open areas. A drop in temperature leads to a decrease in thrust. In addition, temperature changes lead to the formation of condensation. Its presence on the pipe surface creates conditions for the formation of soot layers and the growth of corrosion.

The use of metal in the initial sections of the outlet sandwich pipe, especially close to the boiler or furnace, results in the pipe heating up to dangerous ambient temperatures. Touching such a pipe can result in burns, and building structures are under constant threat of fire. That is, when installing sandwich pipes in a bathhouse, it is necessary to take measures to eliminate this threat.

The use of such pipes to create systems for removing combustion products has solved most of the problems identified above and allows you to install a sandwich chimney yourself.

Properties of sandwich chimneys

Among the properties inherent in chimneys made from sandwich panels, some undeniable advantages can be identified:

light weight;
compatibility with all devices used to generate thermal energy;
aesthetic appearance;
high resistance to corrosion;
reduced risk of fire building structure;
reducing the amount of soot accumulating inside the pipe;
high assembly installation work;
the ability to install sandwich pipes both inside and outside the building.

At the same time, the consumer must understand that the cost of a stainless steel chimney exceeds the price of a similar structure made of galvanized material. Another drawback that can manifest itself in the presence of installation errors or violations of assembly technology is loss of tightness. Another reason why a chimney may lose its tightness is the result of long-term use.

What is needed for chimney installation work?

Manufacturers engaged in the production of stainless steel pipes complete their products with fasteners that are necessary for their installation. Therefore, when purchasing a kit, it is advisable to check their availability.

Installation of sandwich pipes may require some Additional materials and tools, including the following:

bracket holding the wall transition unit;
fasteners;
clamps corresponding to the pipe size;
plugs;
marking marker;
sealant with increased requirements for fire resistance, up to 1000 degrees.

Chimney installation - some subtleties

Installation work must be carried out taking into account certain technological subtleties. For example, the final installation diagram of a sandwich chimney should take into account that most of the structure should be located indoors. This will reduce heat losses during the heating season. In the process of developing a gas exhaust system diagram, it is necessary to take into account that horizontal sections should not exceed one meter in length.

In addition, there are selection tables on the basis of which you can select the diameter of the pipeline.

Table 1.

By the way, when making your own calculations, it is necessary to take into account the fact that the thickness of thermal insulation is directly related to the power of the boiler or furnace equipment. So, for a boiler with a power of 0.6 kW, insulation with a thickness of 25 mm is required. The higher the power, the higher the power, the thermal insulation should be thicker.

Data on the applicability of pipes must be specified in the operating or manual instructions.

Another task that needs to be solved when drawing up a diagram is ensuring fire safety, that is, pipes should not interface with other engineering communications, this is especially true for gas communications. In addition, it is necessary to place sections of the chimney at a certain distance from wooden structures. To fix the structure, it is necessary to use specially shaped steel brackets. The minimum step for installing fasteners for pipeline installation must be at least 1 meter.

When designing a structure, it is necessary to equip an inspection door through which the structure will be inspected and cleaned of soot.

The installation of this structure must be completed without any defects. Most often, errors and defects in pipeline installation are made for the following reasons:

errors in calculations and wiring diagram;
failure to comply with technological discipline.
use of low-grade materials, tools, fasteners.

Price issue

No one will argue that installing a sandwich chimney with your own hands allows you to reduce the cost of home improvement. But, nevertheless, it is better to entrust this work to professionals.

Despite the apparent ease of installation, you need to know that the price directly depends on the method of performing the work. It can be done “by smoke” or “by condensate”. When choosing the first method, it will be necessary to use tees through which condensate will be drained. With the second assembly and installation option, no additional components are required.

We must always remember that installing a sandwich chimney is a very important and responsible procedure. And if, nevertheless, the homeowner decides to independently assemble and install a chimney from a sandwich pipe, then he must be aware of the full extent of responsibility for this detail.

Output through the wall

The chimney outlet through the wall is carried out if the work is carried out in an already erected building. In this case, the chimney will pass along external wall building and the homeowner must provide measures to protect the wall from the effects of the temperature emanating from the chimney.

When building a new house, the chimney system is installed inside the building, in which case heat losses are minimized.

When deciding to install a pipe through a log house, you must be aware that it will have to be insulated with materials such as basalt wool, asbestos or brick. This operation must be carried out in accordance with fire safety requirements. This approach will minimize the cost of its maintenance with a long service life.

Where to start when going through a wall

Purchasing a chimney

The purchased chimney pipe must correspond to the diagram developed before installation. The length of the chimney must also correspond to the calculated data. A height that is too low will create problems with draft; soot generated during the combustion process will constantly enter the room where the heating device is installed; a height that is too long, on the contrary, will cause accelerated combustion of the fuel, and as a result, additional heat will be released into the atmosphere.

Important! Experts note that the length of the gas exhaust system should range from 5 to 10 meters.

The kit of the purchased chimney, in addition to the standard fasteners, should include elbows, tees and, of course, pipes.

General conditions for passing through a wall

In fact, the arrangement of a passage through a wall or through a roof can be done at the design stage. That is, the designer has every opportunity to include in the documentation the junction of the chimney through the wall. At the same time, he must and will be guided by the requirements of GOST, SNiP and SP for fire safety. Thus, the homeowner can be confident that this unit will be completely safe.

When crossing a wall, it is necessary to take into account that there should be no engineering structures near the pipe that are unprotected from heat. The minimum distance to them should be about 400 mm. If it is not possible to ensure this distance, then measures must be taken to additionally insulate the pipe.

Passage through the wall of a log structure

Before laying a chimney through a wall made of logs or timber, it is necessary to prepare a hole. If the building is just being built, then, directly when assembling the crowns of the log house, using a gas or electric saw, cut a piece of log or timber in the laid crown. Its size must exceed the diameter of the chimney.

If the decision is made to pass the wall using round hole, then before you start making it, it makes sense to drill a center hole; its presence will allow you to drill using core drills or “ballerina drills”.

Note: When arranging a junction through the wall of a frame-panel house, it makes sense to perform preliminary drilling and then mark it. The hole can be made using a ballerina or an electric jigsaw.

Passage through the wall of a building made of logs is carried out in the following ways:

you can use a telescopic unit, that is, several pipes made of heat-insulating material and with a diameter exceeding the chimney. In this case, the pipes must be inserted into each other;
the chimney can be routed through the wall, without the use of additional pipes, but the space between the walls and it must be lined with thermal insulation materials, such as basalt wool.

Passage through a brick wall

For arranging a passage through a wall built of brick or blocks with different fillers. Before carrying out its penetration, it is necessary to carry out markings. For these purposes, it is advisable to use a laser measuring tool. In this case, errors will be minimized. When making a hole, you must remember that such deformation of the load-bearing wall can lead to the appearance of cracks. Therefore, builders must take measures to prevent their formation, for example, install a pre-prepared frame in it, which will prevent the wall structure from sagging.

The installation itself is carried out in several operations:
a pipe must be installed at the outlet of the boiler;
install a tee with a valve built into it;
After installing the tee, pass a sandwich pipe through a pre-prepared hole and connect it to the tee.

The space around the pipe must be filled with fireproof material. It is necessary to install shields at the entrance and exit of the pipe to cover the transition. This shield can be made in several modifications, for example, it can be made of an asbestos sheet and a sheet of stainless or galvanized steel attached to it on top.

Subsequently, the chimney can be assembled as the children's designer. After the wall has been passed, work begins on attaching the chimney to the wall.

The homeowner, when installing a chimney from sandwich pipes with his own hands, must understand that assembling a gas exhaust system is a very responsible undertaking and the safety of the building structure and the residents living in it largely depends on it.

There are times when it is not possible to remove the chimney pipe in the usual way - through the roof, and then you have to install a chimney through the wall. In order for the functioning of the chimney to be as efficient as possible, it is necessary to select the most suitable pipes for the boiler, carry out high-quality installation of the chimney, and, if necessary, insulate it.

Brick chimneys, which were once very popular, are losing their relevance and are being used more and more today. These products are easy to install and inexpensive. Their surface is smooth; these pipes do not need to be insulated.

Advantages and disadvantages of a chimney through the wall

By venting the chimney through the wall you will get the following advantages:

the chimney pipe almost completely protrudes onto the street, rather than passing through the entire house;
You can install the product both at the construction stage and after the house has been built, for example, during the installation of a heating system;
there is no need to make holes in the ceilings when the boiler is located on the ground floor of a building several floors high;
the integrity of the roof is maintained;
When assembling and installing a chimney through a wall, there will not be any particular difficulties.

Chimney through a wall in a wooden house

Despite the large number of advantages, the design also has disadvantages and they must be taken into account:

Required condition for installing a chimney through a wall is .
Inside or outside the house, you will need to allocate a fairly large horizontal area for such a chimney.
According to experts, the external gas exhaust pipe has low productivity.
It is unlikely that the product will fit the design of the room, so you will have to get confused here.

Installation of a chimney through the wall

Installation

Before proceeding directly to installation, it is necessary to carry out a number of preparatory measures, including calculating the boiler power, determining optimal diameter pipes, as well as the thickness of the heat-insulating layer.

It is very important that the diameter of the inner pipe is not less than the diameter of the pipe on the boiler. The boiler is selected based on the criterion of the heated volume, and only after that the components for the chimney are selected for it.

If the diameter of the pipe is larger than the diameter of the pipe, then an adapter must be placed in the middle of them.

When installing pipes of a certain diameter, it is necessary to take into account the power indicators of the heating device. So, for boilers with a power of up to 3.5 kW, the diameter of the pipes should be 8 cm, for equipment with a power of 3.5 to 5.2 kW, pipes with a diameter of 9-11 cm are needed, for products with a power of 5.2 kW - The diameter of the pipes must be greater than 11 cm.

It is also necessary to take into account the thickness thermal insulation layer. When working temperature conditions 250°C, like a gas boiler, the basalt layer should be at least 3 cm.

For wood and liquid fuel boilers with an operating temperature of 400°C - already 5 cm.

Installation of a chimney

There are two ways to exit the chimney through the wall:

The pipes inside the room must be raised a short distance from the ceiling, where they are brought outside.
From the boiler nozzle, pipes lead immediately through the wall in a horizontal position. The advantage of this method is that fewer bends are formed, and this has a positive effect on the performance of the chimney.

Assembling a sandwich pipe when installing the vertical part of a chimney can be done in two variations - “smoke” or “condensate”.

Assembling a chimney “for smoke” and “for condensate”

When installing a pipe along the smoke, gas and combustion products move upward, but here you will have to deal with such a negative aspect as the formation of condensation that accumulates in the pipe. This method has gained popularity in cases where the chimney is assembled through the roof. Here, almost the entire pipe is located in the house, and not much condensate is formed.

Condensate installation is an installation method in which the pipe with its expanded end is directed upward.

With this assembly, the condensate simply flows through the pipe into the glass. The disadvantage of this method is that smoke can leak out if the areas at the joints are not properly sealed.

Condensate collection is used when a chimney passes through a wall: in this case, the condensate is directed into a glass, and the smoke comes out of the joints on the street. This will not affect the well-being and health of the residents of the house.

Basic installation rules

In order for the functioning of the chimney to be as efficient as possible, during the installation process it is necessary to follow a number of rules and recommendations on which not only the performance of the installation will depend, but also safety.

Basic requirements for installing a chimney through a wall:

It is important that the pipe rises above the ridge by at least 50 cm, and preferably 100 cm. The traction force depends on this. The traction force directly depends on this.
The total length of the vertical part of the pipe should ideally be 5-10 meters; if the pipe is located at a greater distance, the draft will be too strong and the fuel will burn out very quickly. If the pipe length is not enough, then the draft, on the contrary, will be weak, and, accordingly, the operation of the heating device will not be very efficient.
To prevent the heat insulator from melting, the first segment of the chimney must consist of a single-circuit pipe. It is necessary to make a joint with a sandwich pipe, while maintaining a distance sufficient to ensure that the fastener does not overheat during operation.
The boiler must be placed on a metal sheet. Insulating the wall from the boiler is done in the same way. For wooden houses, according to SNiP, it is necessary that the boiler and chimney be located at a distance of at least 45 cm from building elements that can catch fire, and 25 cm from parts made of low-flammable materials. To ensure that the outlet hole for the pipe is not too large, the wood must be sheathed with metal, in which case the outlet hole may be 25 cm rather than 45 cm.
Place in the finished hole metal box, through which the pipe is passed, and without any connections, because if necessary, access to them will be very difficult. The cavities in the wall must be filled with heat-insulating material that is not afraid of burning.
Next, you need to sew up the pipe hole from the outside and inside. A metal sheet is used for this.
Then, using brackets, you need to fix the support platform for the chimney outside the building, and a tee should be placed on the outlet section of the pipe. The bottom of the pipe is removable, it has the shape of a glass and condensate, which is formed during the combustion of fuel, gets into it. Often the glass is equipped with a tap and a drainage hose. Condensation is a toxic substance, so it is better to drain it away from home.
The chimney at the top is also secured using brackets, which are located one from the other at a distance of no more than a meter. To protect against precipitation, a cap is placed on top of the pipe.
To properly seal the joints, they must be coated with heat-resistant sealant, after which the joint area must be tightened with a clamp.

Insulation of external chimney

As already noted, the most best option chimney is the use of a sandwich pipe, which is not only easy to install, it also does not require additional insulation.

If it is used for smoke removal, then you need to install it in a box, where the distance between the walls of the box and the pipe is filled with a basalt heat insulator. You can also use foil or other non-flammable material as insulation, but the top of the pipe must be covered with a dense layer of heat-insulating non-flammable material.

To summarize all of the above, it is worth saying that installing a chimney through a wall is quite simple. If you strictly follow the installation technology, this procedure will not take much time and effort, and the heating device will delight you with its operating efficiency and good traction.
