A perfect connection of the kitchen hood to the ventilation will ensure complete removal of volatile substances formed during cooking. Not all of them are pleasant and healthy; many are toxic and negatively affect the sense of smell. Believe me, it's better exhaust device Nothing and no one can cope with their removal.
For those wishing to install and connect the hood themselves, we suggest that you read this very useful article. The information presented here will help you choose the perfect required type devices and carry out flawlessly installation work. Our information will be useful not only independent craftsmen, but also for those who want to control hired workers.
The author of the article describes in detail the types of kitchen hoods and installation options various designs. The process of connecting the exhaust device to ventilation is thoroughly analyzed. Photo selections and video instructions are used as an excellent informative addition to the text.
To improve the microclimate and rid the room of odors, soot and burning, a kitchen hood is used. Depending on the internal structure it can remove exhaust air, purify it, or alternately operate in each of these two modes.
In the first case, the equipment is evacuated air masses from the room to the atmosphere. To do this, a special pipe is used - an air duct.
Models that draw in exhaust air and release it into the atmosphere are easy to use and maintain. They do not require regular purchase of expensive filters
Models of the second type are recirculating. For their full functioning, they do not need to be included in the ventilation system.
They need power to draw in waste air that accumulates, for example, over a frying pan frying potatoes. Particles of fat, soot and the smell of cooking food get inside the device.
The grease filter takes the hit first, then comes the turn of the carbon filter. It is he who absorbs all impurities and releases purified air back into the room, releasing it through small holes in the housing.
Option kitchen appliances, which does not require inclusion in the ventilation system, is characterized by large demands - for the operation of the equipment it will be necessary to periodically purchase filtering devices, usually carbon
The third type is combined models. They can operate in both drainage and cleaning modes. In the first case, to ensure performance kitchen hood it will need to be connected to ventilation. And in the second - installing a cleaning filter.
Choose the right option to be used during use. Moreover, depending on the model of the device, its settings may differ.
For example, for hoods with a cleaning mode from LEX, the manufacturer recommends first installing carbon filters. Then take the plugs that come with the exhaust equipment and close the side and top holes, which are intended for connection to the ventilation system.
Plugs allow you to prevent the uncontrolled escape of air from inside the device - first it is fully filtered, and only then it comes out through the holes intended for these purposes
In addition to the principle of operation, hoods differ in installation options - they can be built-in or open.
And they all differ in shape, which determines the possible location of the exhaust equipment.

Installing and connecting a hood in the kitchen has long been no less necessary, just like installing a gas stove or refrigerator. A kitchen hood can keep furniture and kitchen surfaces free from dirt, and is also needed to clean the air in the room.
Three main types of hoods used in the kitchen.
The principle of operation of exhaust devices and types of hoods
The connection method and operation process of the exhaust device depend on its type and operating principle. There are exhaust systems that do not even need to be connected to ventilation, since they operate autonomously.
Scheme for connecting the hood to ventilation At the moment, several types of exhaust devices are distinguished based on the principle.
First, these are classic or dome-type hoods that remove polluted air through a ventilation system. Secondly, recirculating hoods are increasingly coming into use, the principle of which is that they suck in exhaust air, pass it through filters and return it back. And thirdly, these are combined hoods that can operate in both exhaust and filtering modes.
There are many more types of exhaust devices based on the installation method. These include:
- Built-in, installed directly into the kitchen furniture. TO this species devices usually include recirculation and classical types;
- Hanging ones that are attached to kitchen cabinet directly above the hob. They can only be recirculation type exhaust systems;
- Wall-mounted, which are mounted above the stove on the wall. Devices of the classical and combined type have this design;
- Island units, mounted to the ceiling above the hob if it is located in the center of the kitchen. Usually they are systems of a combined and classic type;
- Angular. They look like corner design and work according to the classic or combined type.
Determining the type and power of a kitchen hood
When purchasing an exhaust system, you should take into account its dimensions: area work surface there should be no hood less area according to a specific algorithm and its main points include:
- The presence and location of the ventilation hole, but not in a situation with recirculation systems, where such a factor does not play any significance;
- Determining the type of slab or hob;
- Taking into account the diameter of the exhaust adapter that connects the system to the ventilation duct.
The required extraction power is selected in accordance with the width of the exhaust adapter. The narrower the hole, the more power the device needs.
Table for determining the required hood power in m 3 / hour based on the kitchen area and ceiling height Such a choice is an entirely individual matter, but purchasing a powerful device is not always justified. The system is selected according to the diameter of the ventilation duct, and in the case of a powerful device, a decent amount of electricity will be spent, and the efficiency will remain low. A significant volume of air sucked in by a powerful hood cannot be pushed through a narrow ventilation channel. According to statistical results, the maximum performance of the device is achieved at low fan speeds.
Tools and materials for hood installation
Installing a hood, like many household jobs, will require the use of a specific set of tools. It is better to prepare them in advance so as not to waste time searching for them later. You will need:
- Drill or hammer drill. Much will depend on where exactly the wall will need to be drilled: if in interior partition- then a drill will do, but if in concrete floor- you can’t do without a hammer drill;
- Screwdriver;
- Roulette and building level;
- Hammer.
Hood installation rules
There is nothing complicated about installing an exhaust hood in the kitchen. In the presence of the right tools and certain skills, it can be installed on your own in just a few hours. Before installation, it would be a good idea to read the included instructions.
For each type of exhaust devices there are general rules installations.
To begin with, the distance from the hood to the stove must be at least 75 cm for a gas stove and at least 65 cm for all other types of stoves. With less distance, your exhaust system may begin to melt. There is no maximum installation height; the main thing is that it is convenient for the user to use it.
Advice: If the exhaust system will exhaust air into ventilation, the air duct must be laid with a minimum number of bends. It must be borne in mind that each 90-degree angle reduces the efficiency of the device by at least 10%.
Ideally, the air duct in the kitchen should be made of plastic. Plastic is much easier to disguise, and it looks much more aesthetically pleasing than corrugated pipes. Among other things, the corrugation may hum during operation. To reduce noise levels, such pipes need to be stretched as much as possible during installation.
The hood must be grounded; this is required by basic safety regulations. During operation, the exhaust device encounters steam high temperature and condensate when cooling hot air. This means that the landlady or one of the occupants is at risk of getting hit electric shock in the absence of grounding.
Installation procedure for the exhaust device
Let's consider the procedure for installing exhaust systems depending on the type of hood being installed.
Installation of a classic type hood
It is quite possible to install a classic type exhaust device in the kitchen on your own. The hood is usually installed after installing all kitchen furniture. Therefore, even when ordering a kitchen wall, you will need to first leave space for the exhaust device.
The first thing you need to think about is how the air duct in the kitchen will be laid, and how you will disguise it. In the case of a classic hood, the air duct will most likely be located on top of the cabinets. In such a situation, the corrugation can be hidden behind decorative panels.
Next you need to move on to installing the fasteners. Since dome exhaust devices weigh quite a lot, they are usually installed on dowels. Using a drill or hammer drill, make holes in the wall and insert dowels. Then install the support on which the hood will be mounted.
After installing the hood, you must connect the air duct. In classic exhaust systems it is attached at the top. Take your time when attaching ductwork to your home ventilation system. Before the final stage, it is necessary to carefully check the operation of the device, namely the presence of traction. If everything is as it should be, the hood is connected to the ventilation duct, and the air duct is masked.
Installation of a built-in hood
Installation of this device has some difficulties. But in terms of aesthetics, the built-in hood is in no way inferior to a flat recirculation hood, and in terms of power, a standard dome hood. The built-in exhaust system differs from the dome one in the absence of an external casing, which performs a purely decorative function and hides the “insides” of the device. At correct installation such a hood is practically invisible in the kitchen. This option is ideal in a kitchen made in a classic or rustic style, where the availability of fashionable and modern devices not particularly appropriate. In a situation where a built-in hood is installed in the kitchen, only its control panel catches the eye.
The built-in hood is installed above the stove with a hidden air duct. Such devices are built directly into kitchen furniture, which is the main difficulty of their installation. and here, for installation, certain skills and abilities will be needed. A built-in hood is installed in a cabinet designed specifically for this purpose, which is mounted directly above the stove. It would be very nice if the cabinet was made to accommodate the system. But it is possible to use the most ordinary cabinet. If you have a regular wall cabinet, just temporarily remove all the shelves and the bottom. It is worth installing additional fasteners to make the cabinet more rigid. You will also need to make a hole in its upper part for attaching the air duct. This hole can be made without any problems with an ordinary jigsaw.
After preparing the cabinet, you can proceed to installing the hood itself. As in the case of the classic type, we attach the supports to dowels, mount the hood, and install the cabinet. After installing the exhaust device, we attach the air duct and check the operation of the hood.
Purchasing such equipment will become pointless if guests catch the eye of the corrugation visible in the kitchen. One of the options for hiding the air duct from view is to lay corrugated pipe inside kitchen furniture. It is also possible to mount plastic air duct into the kitchen wall. Or use decorative panels to hide.
Installation of a recirculating hood
Recirculation exhaust devices are the easiest to install. The principle of their operation is based on air filtration, which means the complete absence of an air duct. This hood is mounted to the kitchen wall. The disadvantages of recirculating exhaust devices include their relatively low power and the need to replace carbon filters twice a year.
The principle of operation of a recirculating hood in the kitchen. Mounting the hood
To mount a certain type of hood on a wall, in a corner, on a cabinet or on the ceiling, there are fasteners that are included with purchase. For correct fastening hoods, it is important to strictly follow the instructions included in the kit. To drill holes in the surface for mounting the hood, you need to attach the module, make markings using a level, and then start drilling holes.
Connecting a kitchen hood to a ventilation shaft
For dome or combined type hoods, an indispensable condition is the installation of a ventilation duct or corrugated pipe. This in no way depends on the distance of the exhaust opening from the hob or the location of installation of the exhaust module. Their connection is mandatory.
Connection to wall ventilation with non-return valve. To connect the hood to ventilation, use:
- corrugated pipes, which are used in situations where it is possible to hide it from human eyes;
- polypropylene pipes, assembled from complete modules and having different shapes.
To connect the adapter pipe you need a grid of the same size ventilation duct with hole for adapter. The pipe is attached to the ventilation hole and to the exhaust system using a variety of clamps and sealant. The diameter of the connecting pipe is selected in accordance with the diameter of the hood outlet and the ventilation hole.
Connecting a kitchen hood to electricity
At first it seems that the connection process is simple, but there are some nuances in it.
If installation of the device was not considered during the last repair work, there is a possibility that the power cord may be too short to connect to the nearest outlet.
You can use a carrier, but it is a temporary option. The socket can be installed both on the wall and on the surface of the cabinet. You just need to determine with maximum accuracy the location of the outlet, taking into account that it should not be located next to the sink or stove.
The most acceptable option for installing an outlet would be a place hidden from prying eyes above the kitchen modules.
Any novice craftsman can handle the selection, installation and connection of the hood. Enough to follow in the correct order actions and strictly follow the instructions. And you will certainly succeed.
With or without a connection to ventilation, they play in the kitchen not only the role of removing vapors and aromas for the purpose of environmental safety. They also prevent damage to surfaces. Various fumes, fuel combustion products and fat residues in the air gradually accumulate on walls, work surfaces, ceilings and floors. As a result of such exposure, they begin to fade and deteriorate from fat and other deposits. Using a hood, these processes can be minimized, which will save your money and extend the life of your kitchen equipment.
Types of flow hoods
Models and varieties of the devices in question differ in size, design, price, and operating principle. Kitchen hoods with ventilation connections are used to maximize air removal from the space above the work area. kitchen surface and its subsequent deactivation into ventilation through the air duct.
The units under consideration are divided into two types:
- Passive models. The design does not provide for installation electric motor. The entire work process occurs due to the draft of the ventilation channel system.
- Active kitchen hoods with a connection to ventilation function thanks to the additional connection of electric motors that are located inside the dome. The motors provide a powerful air flow that captures soot, soot, and droplets of fat.
Arrangement
Any type of flow-through exhaust structure is mounted directly above the stove. The unit is connected to ventilation shafts by special air ducts. This can be a tin box or metal corrugation. To avoid unwanted noise, air inlets are equipped with soundproofing material. They will not spoil the aesthetic appearance if you disguise the device behind suspended ceilings.
At the neck of the main device, the air ducts are fixed using clamps. In addition to the elements considered, hoods include the following components:
- Coarse filter. It protects the devices themselves from layers of grease and soot.
- Fine filter. Serves to remove odor. Consists, as a rule, of carbon elements.
Timely replacement and cleaning of filters will not only increase the efficiency of the hood, but also extend the service life of the unit itself.
Hood without duct
Such a device operates as a recirculation device and does not require connection to ventilation ducts. The air is sucked into the filtration unit by means of a fan, where it is cleaned of odors, burning, excess moisture and fat. The efficiency of the device depends on its power and filtration system. Kitchen hoods without a ventilation connection are equipped with two main filter units.
The first system serves to eliminate grease in the air and also provides rough cleaning. These elements are made of aluminum or acrylic. The first option is more effective because it lasts longer and is easy to clean.
The following system fights unpleasant odors, excess moisture, and combustion residues. The main element is It requires regular replacement (about once a quarter).
Types of kitchen hoods without connection to ventilation
All the devices under consideration work on the same principle, but differ in the type of installation, namely:
- The classic version is in the form of a flat umbrella. It does not have any special design sophistications. Has established itself as good hood for small kitchens.
- Hanging model. It is installed above the stove, the air flow is emitted from the front, which makes it possible to mount cabinets on it.
- Built-in version. Allows you to hide the device inside furniture. The device is compact and has high power ratings.
- Kitchen hoods without connection to ventilation with telescopic equipment. These varieties can be pulled closer to the work surface if necessary.
The units under consideration perform various functional tasks, depending on where they will be mounted (in the middle, in a corner or in a separate way).
Advantages and disadvantages of ductless hoods
Kitchen and any other appliances have their pros and cons. An exhaust device without connection to the ventilation system has a number of advantages:
- Elementary installation that does not require the use of additional fittings and connecting hoses. Installing the device yourself is not difficult.
- Economical. Considering that even kitchen hoods (60) with a connection to ventilation use an order of magnitude more energy, this modification can rightfully be called cost-effective.
- The cost of the design in question is lower than a similar system with an air duct.
The disadvantage of such units is the need to regularly replace filter elements. This will have to be done at least once a quarter. Kitchen hoods without connection to ventilation, the prices of which start from 5 thousand rubles, will become a reliable assistant in your kitchen.
without duct?
Devices operating in recirculation mode are easier to install than kitchen hoods connected to ventilation. This is due to the fact that they do not require interaction with the ventilation shaft. The main thing with these devices is to change the filter elements regularly.
You must first ensure that there is a power supply near the site. Before installing the unit, you should mark the mounting points, drill holes, install dowels or screws for subsequent fixation of the device. The next step is to mount the hood on the wall, connect it to an outlet and test it.
Installation of a unit with an air duct
By by and large, connecting the kitchen hood to the ventilation will not pose any special problems. The main thing is that all connections are tightly and securely fixed. When performing work, you need to consider the following recommendations:
- The connection should not completely block the ventilation channel, so that natural air draft occurs when the device is turned off.
- Normal operation of the unit will ensure the passage of air flow without additional interference.
- The length of the duct and the number of curls should be kept to a minimum.
- Choosing between corrugated and smooth surface pipes, it should be taken into account that the first option bends well, but retards the flow.
- The duct must have smooth transitions at bends.
- Additional air flow after ventilation or constant supply from the street will make the hood more efficient.
- It is prohibited to install a device with an outlet into the smoke duct of a gas water heater.
The method of connecting a hood to ventilation yourself is not particularly difficult, provided that certain nuances and technological subtleties are observed.
Conclusion
Having studied the features of the device, the principle of operation, the nuances of operation and installation, we can conclude that the hood must certainly be present in the kitchen. The choice of modification depends on the size of the room, the intensity of the work process, financial capabilities and your own preferences.
Connecting a hood to ventilation, the operating principle of which is based on the suction of air flow and its subsequent transportation to ventilation shafts, is more complicated and requires certain calculations. For example, excessively long air ducts will look unsightly and reduce the efficiency of the device itself. If certain points are observed, installation work is very simple and straightforward.
The option without an air duct is much simpler to install, and its price is lower. However, there are some peculiarities here. Regular replacement of filter elements will be required, otherwise the efficiency of the hood will noticeably decrease. Devices without interaction with ventilation have several types of fastening, which allows you to choose them to suit any size and interior of the room.
The kitchen is the main room in any apartment or country house, here the hostess spends quite a lot of time every day, and all family members are sure to come here at least twice a day. In this small but quite cozy room, the delicious aromas of homemade pies and cooked food are constantly in the air. To prevent various odors from spreading throughout the entire apartment, it is necessary to correct connection kitchen hood.
Before you go to a specialized store to make a purchase, you need to discuss with everyone at home hood type so that there are no disagreements later.
Please do before purchasing necessary calculations, what power do you need for the hood depending on the cubic capacity of the kitchen.
Manufacturers household appliances launched the production of different exhaust systems, which not only have differences in installation, but also function differently.
- Wall option - big choice case design, it will be easy to match your headset. Installation is carried out above the slab on the adjacent wall.
- Corner- are considered ideal solution for a small kitchen, where every centimeter is valuable, installation is carried out on the wall in the corner.
- Hanging type- they are flat, suspended above the stove under the wall cabinet, and fit perfectly into the interior.
- Built-in type- installed inside the headset.
- Island - universal type hoods are used in large rooms where the stove and cutting table are in the middle of the kitchen.
You made a choice and purchased the option that you think is best. Now a natural question arises: how to connect the hood in the kitchen so that everything works correctly, fulfilling the required sanitary standards and security measures.
Connection requirements
First of all, check whether the apartment has grounding. If you live in a house with built-in electric stoves, then this issue disappears - grounding was carried out during construction. If you don’t have one, don’t be upset, there are many options for how to properly ground a modern city apartment, and what conditions are required for this. It will be easier for those who have own house. Read more about these methods in the article on grounding.
We must not forget about separate outlet for a hood that is installed at the level of the system hood or slightly higher: in this way it is connected to the electrical network of an apartment or private house.
You will have enough general knowledge of the operating principles of similar systems to adequately cope with the installation. You can find detailed videos on the Internet that will help you understand the nuances of this process.
Ventilation features
During the construction of any housing construction suitable for habitation, the presence of ventilation system. When you or a called technician connects the hood in the kitchen, it is disrupted in any case. To reduce damage to a minimum, it is recommended to install additional box with valve.
The principle of operation of such a valve is very simple: when the hood is turned off, it is closed with a lid, and the air comes out by gravity; when food is cooked and the hood is turned on, the valve closes the hole with the force of air pressure from the fan natural ventilation. The main advantage of such a system is reverse thrust missing completely.
At home old building are equipped with an outdated natural ventilation system, so before connecting a kitchen hood to home ventilation, you must invite a specialist for consultation. Only he can tell you what power the model needs.
Many users take it outside individually: drill outer wall and remove all odors into a personal window with a 100% guarantee.
Connection steps
Work must begin when all the furniture in the room is already in its specific place, especially when the hood connection diagram is built into the kitchen unit.
Regardless of the type, the hood is located above the surface of the stove at a height of at least 60 cm, and the final height will depend on the height of the housewife, so that it is convenient to cook and not hit your head on the sharp edges of the umbrella. This way you will comply with all basic safety requirements.
You can install a simple hood model yourself; you don’t need any special knowledge for this - you need to be able to use a standard set of tools, and have the desire to do everything conscientiously, with excellent quality.
We will consider a simple mounting of the exhaust system housing to the wall of the room:
- We fix the U-shaped shape with dowels corner frame- this will be a support for the entire body.
- If they interfere gas pipes, then we take special long screws in the form studs- on one side they look like an ordinary self-tapping screw, and on the other there is a thread for a nut. First, screw them in like self-tapping screws, and then install the exhaust system housing on the nuts - as a result, the hood will be at the required distance from the wall.
Self-tapping screw
- We fix it on the neck of the umbrella corrugation using a special clamp.
- We connect the structure to the home electrical network using special socket.
- We check the operation of the entire system. If everything functions correctly, then we connect the corrugation to a special plastic grille, which decorates the entrance of the ventilation shaft. Pre-coat the joint area sealant to eliminate losses during system operation.
Attaching the corrugation to the grille
When installing hood outlets, adhere to simple rule- the fewer pipe bends, the better the traction. Each turn reduces efficiency by 10%.
System filters need to be washed periodically, and fan bearings lubricate. You will learn how often to do this from the operating instructions.
Separate line or outlet
If there is grounding in the house, then it is enough to install only an outlet to connect the hood to electricity. Here we must remember that it must be placed above the system umbrella so that dirt does not fall on the body.
When there is no grounding, it is necessary to carry out separate line from the transfer case. It’s good if it’s on the wall in the hallway - you just need to drill the wall, take out the wires and fix the socket in the right place.
If the distributor is located far away, then major work awaits: cutting the wall, laying a wire, connecting to the electrical panel. And this is a separate conversation.
How to properly install sockets for connecting all household appliances on modern kitchen, shown in the diagram.
Although many home craftsmen do not trust it, it copes with the task much better than round or round plastic pipes. square section. Installation is much cheaper, there is practically no loss of efficiency, which cannot be said about air duct pipes. During installation, it stretches as much as possible, which reduces the noise level.
It is necessary to clean corrugated pipes and plastic pipes 2 times a year so that they do not become heavily clogged with specific accumulations.
Feel free to consult with a professional before installing exhaust system. An excellent option if your friend has already encountered an installation problem - call him to help you, after all the work is completed you will not regret it.
During installation, every stage is important: you just need to make a slight mistake horizontal installation hood, and this will inevitably create problems in the future that are currently invisible. Damaged little sealant and there are gaps left that are invisible, but after some time this will affect the efficiency of the installation. The following mistakes are made quite often, even by professional builders:
- A pipe is walled up in the ventilation shafts, and the exhaust system in which the check valve. When the hood does not work, there is no ventilation of the room, because the valve closes the pipe if the fan does not work.
- When installing, a pipe with a diameter of only 100 mm is used, and this is not enough - you need to use a pipe with with a diameter of at least 125 mm. Then, within an hour, contaminated air with a volume of up to 350 m 3 /h will be removed from the kitchen.
You can eliminate such defects yourself by widening the entrance to the ventilation shaft and installing a special grille with a round entrance for the exhaust system.
After all the work is completed, the stuffiness in the room will disappear, the noise from the hood fan will decrease - in the updated kitchen you can comfortably drink a cup of tea with friends.
Installing a hood in the kitchen involves connecting it to ventilation and power supply. An air purification device is installed both above electric and gas stoves. The main thing to consider is the height of the canopy when installing the structure. You can do this work yourself, without turning to specialists, whose services are expensive.
Kitchen hoods with connection to ventilation
These are supply hoods. They operate in the mode of exhausting air into the air duct. Such models are 100% capable of removing odors and steam from cooking food. Also in retail chains you can find modern air-purifying devices of a combined type. They can operate in air recirculation mode and exhaust air into the ventilation shaft.
Classification of hoods by installation method
- Built-in. Cabinet mounted kitchen set, installed above the stove.
- Hanging. Installed on the wall.
- Island. Attached to the ceiling. They are located in the middle of the room.
- Angular. Mounted in a corner.
Any of the selected models, in terms of adaptability to a specific room and design, must comply with current safety regulations.
What tools will you need?
- Hammer.
- Spanners.
- Hammer.
- Screwdriver.
- Roulette.
- Level.
Installation features
A flat built-in hood is mounted in a pre-fabricated cabinet without a bottom. Mounts at the level of the middle shelf. The dimensions of the cabinet and hood must match. To supply the air duct in the cabinet, two holes are made in the middle shelf and on the roof of the built-in unit.
Having measured the required distance (at least 75 cm) from the surface of the stove to the hood, you can begin installing the hood. You need to mark the mounting points on the wall. Using a hammer drill, holes are made for the plastic dowels. The flat hood is secured using 2 self-tapping screws. The dome structure will be securely fixed with at least 4 fasteners.
What power should the hood have?
The required operational capabilities of the air purification device can be calculated using the formula:
Q - optimal extraction power
S – room area,
h – kitchen ceiling height,
Note! According to the requirements, the air in the kitchen must be changed 12 times per hour (a requirement of sanitary standards) - that is why the indicator 12 is present in the formula. The number 1.3 is the minimum reserve ratio. It involves taking into account the number of floors of the building, the length and contamination of the ventilation shaft, the length and bend of the ventilation duct.
You can also use the special one on our website for calculations.
What should the air duct be like?
When installing a built-in hood, plastic or metal (corrugated) air ducts can be used.
Inexpensive air duct is corrugated
Plastic
Plastic pipes are more often installed - they are lightweight, have good sound insulation, and are easy to install. PVC pipes can be either round or rectangular. The ventilation duct is installed at the top above the wall cabinets of the kitchen unit. At the time of buying plastic pipes it is necessary to purchase “L” shaped transitions and sealant.
Corrugation
Also, to connect the hood with ventilation in the kitchen, corrugated air ducts are used - this is more a budget option compared with PVC materials. Corrugations are made from thin-layer aluminum. In terms of sound insulation, this material is much worse than plastic. There is no need to buy adapters; fixation is ensured by clamps. Corrugation stretches to required sizes. When installing, it is better that the accordion be well stretched - the noise level will decrease significantly.
Features of the design of exhaust ventilation ducts
The diameter of the hood must correspond to the diameter of the air duct. If the exhaust pipe is smaller, the hood will work in a stronger mode, and this will lead to damage to the fan motor. A pipe with a smaller diameter also affects noise insulation - when the equipment is operating, the noise level will increase significantly.
It is necessary that all bending angles when installing ventilation ducts are greater than 90 degrees. The operation of ventilation depends on this. And the number of these same bends should be kept to a minimum. The efficiency of the exhaust air purification device depends on this. It's better to give preference plastic systems With round. Not only will dirt and dust not settle in them, but they also have less resistance to the passage of air masses.
Important! The scheme also includes the installation of valves - plastic or film.
Socket installation
Before connecting the hood to the ventilation, you must ensure that there is an outlet. Ideally, electrical installation work should be carried out by a certified professional. However, in practice, as you know, you often have to do this yourself. Moreover, it is mandatory, except for the rules personal safety, is to comply with the following standards:
- The socket is mounted in a place above the wall cabinets of the kitchen unit - at a distance of 5 cm or near the ventilation shaft - at a distance of 20 cm.
- Install the socket at a distance less than 2 m from flooring it is forbidden.
- A grounding device with a current of at least 15 A is required.
- The electrical outlet intended for the hood must be 15-amp or larger.
- When connecting an additional socket to the line, the total power of all connected devices is calculated (no more than 4 kW). If the indicators are higher, then it is better to place the hood on a separate line.
Important! It is prohibited to install an outlet near a sink or gas/electric stoves. The socket must not be installed behind the hood body. You cannot install a socket with a current strength lower than that required for this device. Wires must be double insulated.
How to connect a hood to a ventilation duct
- Before connecting the hood to ventilation duct, you must first buy corrugation with a cross-sectional diameter that fits this model, clamps, and sealant.
- The corrugation is inserted into pre-made holes in the wall cabinet.
- A cabinet with a threaded air duct is fixed to the wall.
- The exhaust air duct is connected to the ventilation duct.
- To connect the hood to the ventilation, it is necessary to bend the corrugation at the exit from wall cabinet kitchen set. You can also use plastic connecting elements for pipes.
- To seal, the joints are treated with silicone. Sealing the ventilation system allows the hood to operate without additional costs.
Important! The corrugated or PVC pipe is secured to the pipe using adapters or clamps. There is no need to seal this area. The main thing is that the adapter matches the size of the hood.
Connecting the kitchen hood to ventilation is carried out taking into account certain parameters, namely, the distance between gas stove and the exhaust device should be 90 cm. If an electric stove is used, then 70 cm. These standards should not be neglected. Minimum distance from gas stove should be 75 cm, and for electric ovens a minimum of 65 cm.
When installing ventilation pipe in the ventilation shaft it is important to make sure that vent did not completely overlap, so you need to install a special grille. It has a special valve, as well as a place for attaching the air duct. When the exhaust device is operating, the valve will close, and when the hood is turned off, the valve will open, facilitating natural ventilation. If it is impossible to install such a grille, then a check valve is installed in the air duct.
How to connect a kitchen hood to ventilation so as not to spoil the interior? All ventilation should be hidden under protective cover, which can be made to match the color of the kitchen set. Thin plastic is often used for these purposes. The final stage, is to check the performance of the equipment. During installation, all elements must be securely fastened so that the hood does not rattle during operation.
