The question of how to install a hood in the kitchen worries many today. When renovating their kitchen, people in most cases think about creating a more efficient ventilation system, because this is not just convenient, but even necessary.
A person who prepares food regularly spends about five hours a day in the kitchen and breathes harmful fumes, including smoke and fumes.
In addition, during cooking, tiny particles and fats are released from food into the air, which also adversely affects human health.
The only way out in this situation is to purchase and install a hood, since neither traditional ventilation systems nor simple ventilation will provide the required effect. How to properly install a hood in the kitchen will be discussed in this article.
Selecting a hood
One of the most important systems In a person’s home, ventilation is what ensures the comfort of his life. In a sufficiently ventilated room, the air is clean and fresh, which makes it simply pleasant to be here, while stuffiness can cause negative reactions in the body, including general weakness and dizziness.
Kitchen hoods are one of the main ventilation units, since cooking is associated with elevated temperature air and harmful emissions, including very unpleasant odors.
The main task of the hood is to clean the air in the room. And the cleaning process itself can occur in different ways. The mounting of the kitchen hood directly depends on this. So, there are two types of operation of modern hoods.
Types of hoods
- The simplest hood device works on the principle of air recirculation. In this case, the air is not removed outside the room, but passes through special filters and returned back. Sometimes such hoods are also called filter hoods or hanging hoods (see also the article about a hanging hood for the kitchen).
Advice! If the ventilation shaft is clean and “pulls” well, then you can remove the valve from the hood and allow it to work with the engine turned off. This is possible in houses with controlled ventilation.
Connecting the hood to ventilation
Since installing a hood in the kitchen is not difficult, you can handle this procedure yourself. But it's better to take an assistant.
- We attach the hood to the wall and mark its future position with a pencil. If you are planning to change kitchen furniture, then you should consider installing the hood in a wall cabinet.
- We drill the walls with a hammer drill for the dowel. You shouldn’t mess around here, since the structure must be “tightly” fixed.
The need to install a special hood over the stove is explained by the desire of users to get rid of extraneous odors and other fumes generated in the kitchen during the cooking process. At the same time, it is possible to ensure the required efficiency of indoor air purification only if certain rules and recommendations are followed, determined by the relevant regulations and standards. In this article we will introduce you to existing species exhaust structures and consider the order of their installation using the example of one of the most common models.
Types of kitchen hoods
Currently on the domestic market household appliances There is a wide range of kitchen hoods, which according to their design are divided into the following types:
- suspended design, which is one of the most convenient to install and practical exhaust devices, suitable for most ordinary users. With all the listed advantages, such a hood, however, is characterized by insufficient productivity;
- an exhaust device built into the walls or ceiling that provides the required efficiency in removing odors and fumes from rooms of a large area;
- an exhaust device designed in the form of a dome, the effect of which extends not only to the stove, but also to the working surfaces of the countertop located near it;
- so-called “island” hood, mounted in the center kitchen area and providing air exchange throughout its entire volume (including above gas stove).
Auxiliary elements (air ducts)
As air channels through which unpleasant odors and fumes are diverted to the ventilation shaft hatch, special air ducts are used, made in the form of:
- corrugated pipe;
- rigid metal box;
- polyvinyl chloride pipes with smooth walls.
To the benefits corrugated pipes should be attributed to their flexibility and relatively low cost. The disadvantage of this budget option air duct is the need for constant care during operation. Used as an air duct metal box more convenient to use, but will require significant expenses from the contractor. The most optimal application option is considered PVC pipes, which is not only easy to install, but also does not require special care. Unlike other air ducts, this pipe is installed strictly above the hood.
Requirements for installation of the hood
Installation procedure kitchen hood will be considered by us using the example of the simplest hanging system, the installation of which requires the following requirements:
- The dimensions of the intake hole must correspond to the size of the gas stove, which ensures maximum effective removal polluted air;
- The height of the hood above the surface of the slab should not be less than 50-60 cm (the optimal distance from heating elements about 75-80 cm), which provides comfortable working conditions. If it is placed too low, the space for working with the stove will be limited, and the body of the device itself may overheat;
- The performance of the exhaust device must correspond to the volume of the room being served and ensure that the air in it is renewed at least 10 times a day. To calculate the exact value of this indicator, it is necessary to determine the basic dimensions of the kitchen room, and then use the following formula: V = SxHx10x1.3, where S and H are the area and height of the serviced room, respectively, and 10 is the minimum air exchange rate (1.3 - correction factor);
- in the case where your house does not have a separate ventilation shaft with access to the kitchen, it is recommended to use a flow-type exhaust device with variable capacity, operating on the principle of air mass recirculation.
Note! Connecting such hoods to an existing ventilation shaft may disrupt the operation of the entire exhaust system generally. In addition, it is not recommended to operate flow devices at full power (maximum performance mode) for long periods of time.
Installation procedure for the hood housing
Installing a hood over a gas stove involves phased implementation a whole range of work operations of the following nature:
- hang the case exhaust device directly above the stove;
- installation of exhaust air ducts, ensuring their reliable connection with the hood and the ventilation shaft hatch;
- supply of electrical power necessary for the operation of the exhaust device.
Important! When preparing a place to install a wall-mounted hood, the main thing is to ensure that it is positioned strictly symmetrically above the gas stove, since even the slightest deviation of the body to the side reduces the efficiency of the device by 10 - 20%.
Direct installation of the hood at the place of its operation is carried out in the following sequence:
- First, the fastening points are carefully marked, taking into account the location of the supporting elements on back wall housings (for these purposes it is most convenient to use a pre-prepared template);
- after that, in accordance with the markings, holes are carefully drilled in the wall into which dowels are driven;
- then the supports used to hang the body are fixed in the dowels using bolts;
- At the final stage of installation, all that remains is to hang the hood itself on the prepared supports (watch the video).
Note! During test hanging, it is necessary to check the correctness of its orientation in various planes, which is verified using a building level and can be corrected by changing the position of the supports (their design allows adjustment within small limits and allows you to hang the hood quite comfortably).
Installation of air ducts and power supply connections
- outlet channels for a wall-mounted kitchen hood are made up of relatively short and straight sections with a minimum number of bends, the radius of which should be chosen as large as possible;
- when using corrugated hoses as a discharge channel, their bending angle should not be less than 90 degrees;
- It is also not recommended to narrow the outlet section of the air duct, which can lead to increased noise;
- The hatch of the ventilation shaft to which the air duct is connected must be completely cleaned of all contaminants accumulated during its operation.
The operation of the exhaust mechanism requires an electrical network, the supply of which must be provided in advance. As a rule, products of this class are equipped with a cord with a plug, for connecting which a specially equipped socket with a grounding contact must be used.
Important! To avoid heating, such an outlet should not be located above the area where the hood is located.
Conclusion
From our description it follows that hanging a hood over a gas stove is not at all difficult, as you can see by watching any video on the relevant topic posted on the Internet. From these videos you will learn how to install a kitchen hood above the stove, as well as existing methods its connection to existing communications.
The distance from the gas stove to the hood is important factor, on which the efficiency of the equipment and the cleanliness of the air in the kitchen depend. Let's look at what this parameter depends on and how the characteristics of the device influence it.
Features of kitchen exhaust equipment
Before you understand at what height to hang the hood, you need to study design features and the operating principle of the device. At its core, a kitchen hood is a design that is designed to forcibly remove gas combustion products and other harmful impurities. The device consists of a housing, an air intake, electrical ventilation parts and a set of filters.
According to their operating principle, hoods are divided into 2 types: flow and circulation. The operation of the first type of equipment is based on the removal of dirty air into ventilation pipes residential building. In this case, it is possible to achieve almost complete air purification, but such a system requires a regular influx of clean air masses from outside.
The second type does not extract air from the kitchen, but filters it through a set of filters built into the system. The main advantages of this equipment include the absence of unnecessary lines. Among the disadvantages are the large amount of time spent on high-quality cleaning.
What types of hoods are there based on installation method?
All hoods available on the market lend themselves to a certain classification. It depends on the method of installation of the equipment. Thus, devices for air purification in the kitchen are divided into:
- hanging;
- built-in;
- wall;
- corner;
- island.
Systems of the first type have a flat shape and are mounted under the shelf of a wall kitchen cabinet located above the stove. The second type is hoods, the design of which is built into a dome or cabinet above the stove. Wall-mounted hardware is installed on the wall above the stove. Equipment corner type used for installation in the corner of the kitchen. Such systems are especially convenient if the slab is located closer to the end of the wall. The last type of equipment is very relevant for kitchens large sizes, where the hood should be installed in the center.
Depending on the shape of the air intake, there are four main types of hoods: vertical, horizontal, flat and domed. Flat systems have a lower surface resembling blinds in the form of rectangles. Sometimes there are low sides on the sides of the surface. They are installed above the stove in a horizontal position. The width of models of such equipment can be 50 and 70 cm. Vertical systems equipped with a lower surface located at an angle. A guide visor is installed in the upper part.
Dome systems are considered the most popular. In shape they resemble a tent, the width of which can range from 50 to 120 cm. The height of the dome itself in most cases is 30–50 cm.
What parameters to consider during installation?
The main factor when installing the system is the height of the hood above the gas stove. Before hanging the equipment, you need to decide on the distance at which it will be installed. In most cases, the installation height of the hood is indicated by the manufacturer in the operating instructions. However, if this recommendation is absent, then the distance can only be determined taking into account certain conditions.
The first of these is safety. It determines the minimum permissible distance between open fire and the lower plastic panel hood, in which the equipment will not ignite. The minimum height will be 60–70 cm.
The second factor is determined by the convenience of cooking. A housewife who spends a lot of time in the kitchen and uses household appliances must independently determine the optimal position of the hood, taking into account the convenient placement of tall pots on the stove.
The third factor is the system’s ability to draw in polluted air from the most hard to reach places on the stove.
Based on all these conditions, we can conclude that a distance of 70 cm is considered optimal. This result may vary depending on the height and size of the person who spends the most time at the stove.
How equipment parameters affect height
The calculation of the distance between the stove and the hood is influenced by the area of the air intake, the type of its location and the power of the equipment. Systems low power need to be suspended at a height of at least 75 cm. More powerful devices capable of processing more than 550 cubic meters per hour allow you to increase the distance.
One more important parameter The dimensions of the system are considered. Its width should not be less than the slab itself. In this case, it will not be able to completely cover the surface that pollutes the air. The average width of the slab is in the range of 50–60 cm. Therefore, hoods with dimensions of 65–70 cm cannot be installed too high above such slabs. Only a system with a width of at least 80 cm can be hung higher.
The position of the air intake also affects the height above the stove. If it is placed at an angle, then the system must be installed so that its lower surface is located at a distance of 60 cm from the stove.
When installing equipment, pay attention to the fact that the materials from which it is made are practically incapable of igniting. Only stains of fats and other substances accumulated on the surface can catch fire.
Many people today are interested in how to install a hood over a gas stove.
The modern kitchen is cluttered with all kinds of household appliances. Not a single person these days can imagine life without a refrigerator, microwave, stove, etc. mandatory elements This also applies to the hood. Finding out how to install it will be useful for everyone.
Why do you need a hood?
First, let’s find out why a stove hood is needed in principle. Let’s say right away that the absence of this attribute in the kitchen can lead to a number of unpleasant moments. The mere fact is that smoke and steam will accumulate in this room, and then all this will lead to gradual destruction facing materials, is no longer good. In addition, the cooking procedure on the stove will go much better if a reliable device absorbs unnecessary fumes or removes them outside.
Varieties
As a rule, there are several types of hoods for installation:
- Fireplace type;
- Built-in;
- Filtering;
- Air intake;
- Ostrovny;
- Corner;
- Wario and so on.
In addition, exhaust systems for stoves also differ in filters:
- Hoods with a metal filter are also called grease traps. Their installation is carried out only if the kitchen is equipped with a shaft for ventilation, since otherwise installation above the stove is useless. Such devices absorb unpleasant fumes and fumes much better if equipped with aluminum filters;
- Hoods with carbon filter installed as a separate attribute (not necessarily directly above the stove). They eliminate perfectly bad smell and are air recirculators.
As you can see, some hoods are capable of cleaning a room by dispersing air with evaporation, passing it through a filter, and then returning it back. Other units equipped with a metal filter completely draw in air without filtering and exhaust it outside.
Recently, universal models have begun to be produced that simultaneously perform both output and filtering. The owner chooses the most comfortable mode for him and adjusts it manually.
In some apartments it is not possible to connect the hood to the ventilation (labor-intensive process of connection and installation, unaesthetic final result and other reasons). Then you have to limit yourself to the recirculation mode, when the unit only filters the air above the stove.
Note! But in this case, you will need to know that this mode is most effective on individual installed hoods with a carbon filter.
Productivity or efficiency
As a rule, models of exhaust systems are capable of pumping different amounts of air (200-1200 cubic meters per hour). But the top rating of hoods is not the model that is more powerful, but the one capable of pumping air at a speed of 500 m3/hour.
The fact is that to calculate efficiency, you need to multiply the volume of the room by 10, and then multiply the result by 1.3. This will give the final performance of the unit, which, carrying out filtration in medium mode (without “overexerting” and without creating excessive noise), will provide excellent purification. This will be the highest efficiency.
Attention ! The passport for a hood model that simultaneously operates in 2 modes usually indicates the power in the mode of removing fumes into the shaft. This means that filtration through another mode will be 40 percent weaker, since its loss when passing through the filter is inevitable.
Among modern hoods, there are no such hoods that would not make any noise after being installed above the stove. This, of course, does not mean that it is impossible to choose the ideal option with the required performance and the least noise.
Note! So, the quietest of installed systems The hood is equipped with a motor sitting in a plastic box with soundproofing properties. The unit does not come into contact with the body at all, as it is protected by special gaskets. And still - 36 dB of noise cannot be avoided.
When choosing a range hood system for your kitchen, you should try to find a model with flawlessly functioning controls. Modifications with “pseudo-sensory” control are considered the most rational. Their microphones are perfectly protected from clogging. Network surges are not as bad for such hoods as for expensive options with touch control.
Installing a hood through a cabinet
The process of installing a hood over a gas stove depends on several things. The type of this kitchen attribute, the location of the shaft, the filtration method, and much more are taken into account.
Installation of an anti-return mechanism (clacker)
Let's first consider how to install a firecracker:
- It is recommended to start by making a cracker over the stove. Galvanized iron or just tin (aluminum is an ideal option) are quite suitable for this.
Note! If you don’t want to tinker, you can purchase a ready-made firecracker sold in stores. This element must be installed in front of the shaft itself.
- For maximum convenience, it is advisable to place the case on a cabinet that hangs above the stove.
Advice ! Initially, the housing is installed quickly. After installing the cabinet, all cracks must be sealed with foam, and the cabinet is firmly glued. This eliminates the possibility of resonance.
- We do not install the firecracker body the first time. First you need to mark the locations of the holes by attaching the product. The cabinet is removable for convenience, and the desired shape is ensured inside.
Advice ! To make it easy to cut the required shape in the cabinet, you must first drill a few holes, and then insert a jigsaw into one of them and start cutting.
- Be sure to make holes in the internal shelves of the cabinet, if any, for the air duct.
Note! Also, don’t forget to make a hole in the top wall, keeping the required margin.
Air duct
We do the following:
- We insert the sheet into the holes made, giving it a square shape at the top of the cabinet;
- We cut it with a small margin, be sure to cut the corners and bend them outward;
- We attach the corrugated cabinet to the wall. We treat all joints and cracks with silicone so that the power of the system does not decrease;
- We fix the product on the cabinet;
- Now we attach the hood to the cabinet, screwing it tightly;
- We place the sheet on the hood, securing it with a clamp;
- We connect the air duct to the shaft, integrating both elements with a universal connector, as shown in the photo;
Advice ! When installing ventilation, you should try to minimize pipe bends as much as possible.
This way, good traction will be ensured, because a large number of turns of the pipe reduces power. She is lost by almost 10 percent .
Standard installation
Not all owners agree to hang a cabinet above the stove, considering it impractical. Indeed, such accessories quickly deteriorate from steam and high humidity, although they provide the hood with an aesthetic appearance.
Note! In addition, most wall cabinets are narrow, and this does not allow the installation of wide hoods in them.
So, to install the exhaust system, do the following:
- We make a rectangular frame from the corners. It will act as reliable support for the body;
- Instead of clamps securing the case to the wall, you can use special self-tapping screws;
- We connect the current to the hood.
Attention ! When connecting, do not forget to take into account the grounding moment, so that when the fans rotate, possible voltage is diverted to the side.
Important points
When installing the hood, you need to pay attention to the following points:
- The standard installation height of the hood above the gas stove should be average. In other words, it should be set neither too low nor too high.
Note! As for the exact dimensions, there is no way to indicate them, since it depends on the specific room, the size of the gas stove and the type of hood. Nevertheless, an approximate height can be given - 750 mm above the slab at least.
- It is important to regularly monitor your hood filters. If this is not done, then they will fail, and this will lead to damage to the unit itself;
- It is also recommended to wash filters frequently to remove grease, otherwise a large amount of accumulated substance can lead to fire;
- The exhaust system should be the same size as the stove, but not wider than it;
- The hood must be installed in a constant position relative to the cooking area.
Note! The fact is that if the hood is offset in relation to the stove even slightly, this will have an extremely negative effect: the steam will not come out effectively enough.
- It is also necessary to ensure that the hood is equipped with an independent power supply system. It is advisable to prepare a special socket.
Note! You must also remember to ensure that the hood is grounded to ensure safe operation of the unit.
- During installation, safety precautions must be observed. If possible, it is better to ask loved one to protect you when securing the hood.
Let us remind you that the hood must be cleaned at least 1-2 times a year to remove fumes. This will eliminate the risk of fire. Now, knowing how to install a hood over a stove, you can save a lot on the services of specialists. Good luck with your work!
For a kitchen with a gas stove, air ventilation remains a matter of paramount importance. And the point here is not about banal comfort, but about the safety of household members. During the combustion process, hazardous substances (at high concentrations) and by-products in the form of soot, soot, deposits and small particles of fat are released. And when, it would seem, the issue has been resolved, and the long-awaited assistant has been acquired, another difficulty arises - how to install a hood over a gas stove and do it correctly?
The question is relevant, because modern man cannot imagine his life without a refrigerator, microwave, or gas stove, so the instructions for installing the exhaust unit will be useful to all owners.

Types of solutions
There are several types of hoods on sale, differing not only in design, but also in the installation method:
- fireplace;
- filtration;
- built-in;
- with air intake;
- vario;
- corner;
- island, etc.
Which one is better? – The answer is different in each case, because it depends on individual requirements and preferences. Some of them operate on the principle of moving air and purifying it, followed by returning it back. Others allow you to completely extract contaminated air from the kitchen and discharge it outside without resorting to additional filtration.
Air removal and purification mechanisms
Recently, they have gone on sale universal solutions allowing oxygen to be purified and removed. If, due to certain circumstances, the household appliance cannot be connected to ventilation duct, it is advisable to focus on the recirculation model.
note! Even the most modern hoods for gas stoves generate a noise of 36 dB during operation. This value is minimal and does not cause acoustic discomfort during operation.
Installing a hood in a cabinet above the hob
Cabinet installation option
Installing a hood over a gas stove and the sequence of work depends on several initial points. First of all, the following are taken into account:
- type and design features kitchen appliance;
- filtering method;
- remoteness of the ventilation shaft;
- furnishing features.
The installation height of the hood above the gas stove varies from 65 to 75 cm (with a tolerance of 5 cm). Exceeding the specified values may result in the unit simply not being able to cope with the removal of dirty air and residual products that end up in the room. A low “landing” also does not bode well: the device will overheat, disturb the owner, and after a short time it may even fail. Be that as it may, but without preliminary preparation There's no need to hang anything.
Anti-return mechanism installation sequence
So, how to properly install a hood over a gas stove? Experts strongly recommend starting work with the installation of an anti-return firecracker. The product is traditionally placed above hob. For its preparation it is better to choose aluminum. In the video below you can find out more about check valve(to the firecracker).
Check valve for ventilation
note! If you don’t have the desire or skills to make such a mechanism yourself, we recommend purchasing a ready-made firecracker. The corresponding solutions are presented in a wide range in specialized stores.
- It is advisable to place the firecracker body on top of a cabinet mounted above the stove. After installation, it is imperative to seal all cracks with foam in order to eliminate the likelihood of resonance.
- At the first stage, the body should not be “tightly” attached, but only placed in such a way that you can mark the locations for the holes, not forgetting to indicate the diameter. This will allow you to prepare the cabinet for installation of the firecracker.
note! If there are shelves in the interior of the furniture, holes for the air duct are also made in them. There should be an exit at the top wall (if there is none, use a jigsaw).
Air duct work
One of the main functional units of the hood above a gas stove in a private house (as well as in an apartment), in addition to the fence itself, is the air duct. It is done in several steps following a strict sequence.
Sequencing
note! If the hood above the gas stove is installed correctly, then the number of bends in the corrugation will be minimal, in ideal – 1.
The draft power inside the air duct depends on the “sleeves”, areas with bends. On each such “knee”, an average of up to 10% of power is lost. Therefore, it is so important to choose the right place to place the cabinet and the exhaust device in it. For greater clarity, it is recommended to watch the video below on assembling the air duct.
Installing an air duct for a kitchen hood
Traditional installation
The overwhelming majority of domestic owners believe that a cabinet above the hob is an impractical option. There is a grain of truth in such an opinion, since under the influence high temperature, steam and soot, almost all accessories lose their original appearance and deteriorate. But in the realities of a small square footage there may simply not be room for a kitchen hood. It will be very inconvenient and difficult to fully use such a cabinet.
Traditional hood placement option
For such cases, it is necessary to organize the entire process in the following sequence:
- 1. From metal corners frame is formed rectangular shape. Its dimensions must be sufficient to accommodate the housing of the exhaust unit.
- 2. The base can be fixed to the wall using self-tapping screws. It is very important to first measure the distance from the gas stove to the hood (the place where you plan to install it).
- 3. The metal frame and the unit itself are installed on self-tapping screws (don’t forget about the air duct).
- 4. The final stage is connecting the device to the mains.
note! Before hanging the hood in the manner described above, you should metal frame grounding When the fans rotate, a small voltage will certainly arise, which must be removed from the device.
