The height of the hood above the hob. How to determine the height of the hood above the hob

The hood is one of the most important elements of the kitchen household appliances. The comfort of being in a place depends on its choice and placement. kitchen area, preservation of the coating of walls, ceilings and furniture, aesthetic appearance kitchens - modern hood has been for a long time important element decor.

An exhaust system is especially relevant in a kitchen with gas stoves - unlike other types of hobs, gas heats the air to a great height, releases harmful decomposition products during its combustion, and burns oxygen.

During intensive cooking, air purification is simply necessary in the room.

When deciding how to install a hood over a gas stove, you should be especially careful about the type of exhaust system; not every design provides optimal performance in rooms with gas.

Basic Requirements

Functionality

A flow hood will remove polluted air, a circular hood will clean the polluted air with filters and return it to the room

All hoods are divided into two large groups: circular and flow-through; in the first, air is passed through filters and returned back. At the same time, the room will remain high humidity, many harmful decomposition products during gas combustion, air with a low oxygen content - the norms for the content of harmful substances may be exceeded.

When using flow-through types, polluted air is removed outside the kitchen area and replaced with fresh air - this type exhaust systems For gas hobs it is preferable.

Aesthetics

The exhaust system should fit optimally into the interior without disturbing the appearance of the kitchen. To do this, hoods are built into furniture (cabinets above the stove), and the color of the work surface, body, or design is selected to match the style of the kitchen.

Many people forget about this, installing especially popular ones in lately modern inclined models in high-tech style made of glass and metal, with black glossy surfaces, in any kitchen, often reminiscent of a classic or Provence style with light wood-look furniture.

Efficiency

The exhaust system in the kitchen should eliminate as much as possible negative consequences when cooking food: foreign odors, water vapor with tiny droplets of fat, particles of soot and soot in the air, high humidity. The hood for a gas stove must be correctly installed above hob, have the appropriate power and performance.

Classification

Based on their design, all existing hoods can be divided into several groups.

Flat

Flat options have a minimalist design and will not stand out from the rest of the kitchen elements

A very common type, a flat worktop is located parallel to the hob. They take up little space, the design is mainly used in circular types.

Dome

Such models capture a larger volume of air during cooking.

One of the most common designs, in appearance they resemble a dome lowered over the hob along a square pipe in the upper part. In almost all designs, this pipe is part of the air duct, and dome hoods are built into a flow-through exhaust system - such designs are very rarely used in circular types.

Retractable

Retractable models are practical, but have a short length, so they capture less air during operation

To increase the service area, the working surface of hoods is often increased by using a retractable module. Typically, such models are built into bottom part a wall kitchen cabinet, in which an air duct can be hidden or, in the case of circular ones, there is space left for placement kitchen accessories. Retractable - a very convenient design when installing an exhaust system in small kitchens.

Corner

Corner models are not so widely used, so the choice of design and functionality may differ from standard options

Placed in the corner of the kitchen, designed for a gas stove turned at an angle of 45 degrees to the main wall. The working surface of the hood has the shape of a square with a truncated corner.

Island

Island options are becoming exclusively in kitchen islands

Designed to be placed in large kitchens, if the hob is located in the center of the room. Typically, the hood is lowered above the hob on a square duct.

Oblique

Inclined models have a stylish appearance and standard functionality

Modern solution kitchen exhaust systems, in which the working panel is located at an angle to the hob. This allows the inclined model, with the same area as the flat horizontal one, to occupy less in the kitchen free space. The design looks most aesthetically pleasing in modern high-tech kitchens.

Tabletop

Just recently appeared new look hoods, saves space for wall cabinets or shelves

The device is mounted in the table next to the hob. During operation, its suction working panel extends vertically upward and air is pumped out.

Hoods are classified according to installation method as follows:

  • Hanging. It is fixed directly above the stove using cables or on the air duct.
  • Built-in. Installed in kitchen furniture from below hanging cabinets.
  • Wall-mounted. Attached to the wall above the hob.

Installation height

The installation height depends on the average height of the person in the family

The main parameter during installation is the distance between the hood and the gas stove; it should not be less than 750 mm. and no more than 900 mm.

This distance is selected taking into account the ergonomic characteristics of the housewife and depends on the power of the hood - more powerful structures can be placed higher. Also, the installation height of the hood above the gas stove in many cases directly depends on the manufacturer’s recommendations, which must be followed first (these requirements are described in the instructions for the device).

Size

The second main parameter is that the width should not be greater than the width of the hob. If structurally it rises to a height greater than the recommended one, it overall dimensions or suction power should be increased.

When deciding how to properly install a hood over a gas stove when using an inclined model, they usually focus on the lower edge of the air intake - the minimum distance to the stove should be 550 mm.

Another important parameter of the hood is its depth; usually this parameter corresponds to the dimensions of the hob and is typical for its width.

Installation of exhaust systems

Installation may vary depending on system type

Installing a kitchen hood with your own hands is quite simple if you follow the instructions and work procedure. Manufacturers often produce kitchen hoods that combine two operating modes - circular and flow-through.

Installation of a circular hood

Using a circular mode in kitchens with a gas hob is not a very good solution. An autonomous circular hood above a gas stove will not be able to provide the necessary comfort in the kitchen; its carbon filters, unlike electric stoves, will quickly become clogged with gas combustion products, which will lead to additional economic costs.

Installing a circular kitchen hood usually does not cause big problems: it can be attached directly to a straight wall or in a corner, built into furniture, or lowered above the hob through a pipe or on cables. The sequence of work when installing it on the wall is as follows:

  • The connection location is pre-determined; if the socket nearby is not very suitable or it is located far away, the point is moved. In this case, it may be necessary to chip the walls and install new socket with wiring for connection.
  • Attachment points that specify the location of the hood are marked in the wall at the required height, holes are drilled using a hammer drill and dowels are driven in. It is important to check the correct installation using building level— the working surface of the hood must be located strictly horizontally above the stove.
  • The hood is screwed to the wall with screws through the mounting holes, if it interferes gas pipe, it extends from the wall and is attached to long studs with nuts. You can also place a block of appropriate thickness between the wall and the hood and attach the hood to it or the wall with dowels using long screws through the beam.

Installation of flow hood

When deciding how to hang a hood over the stove, you should know that a flow-through hood will require the installation of an air duct system to connect it to the ventilation hole of a common house shaft, or an external air outlet in a wall, window or ceiling.

Installation of air ducts with the installation of a hood is easy to do with your own hands if you follow a certain procedure.

Required tools and materials

Selection of air ducts. For the installation of flow-through systems in everyday life, two types of air ducts are most often used: corrugated aluminum or plastic with a square or round cross-section.

Example of aluminum corrugated pipe

Repair is a reason for quarrels in married couple. What style to choose in the apartment, what color the curtains will be, what flooring, wallpaper, furniture, bathroom - all these integral components of home improvement depend on your taste and preferences. You independently select the design, determine the layout and location of the planned things.

When installing a hood, it is necessary to take into account the mandatory distance between the device and the stove

But no matter how you like it, there are certain rules, which should be taken into account when equipping your new home. One of these obligations will be the distance between the hob and the hood.

Where is the best place to hang a hood?

Foreign smell is that small problem that technicians of many generations have fought over. Ventilation time is half an hour per winter cold has long since passed. You no longer need to open the windows in the rain to get rid of the stagnant smell of just cooked stew or hodgepodge. There is no longer any need to drive foreign odors around the house through drafts. These old-fashioned methods completely unsuitable for modern technologies created to make life easier for humans.

Modern houses and apartments began to be built taking into account ventilation systems. They provide the necessary air circulation in the home and support comfortable conditions life. Also, the ventilation system is designed not only to ensure the entry of air, but also to remove foreign odors. Often such equipment can easily cope with the removal of excessive sources of extraneous odors. But if this does not happen, then a newfangled word in household appliances for the kitchen comes to the aid of housewives - the hood. This attribute is required for cooking delicious dinners and invigorating breakfasts.

You have a new modern, powerful and stylish thing in your kitchen. It will help prevent the spread of odors, moisture and excess fat throughout the kitchen. Some more powerful models can also combat odors in neighboring rooms. This attribute of modern technology requires not only careful maintenance. It is also important to hang it properly in the kitchen. The hood should be directly above the stove in order to rid you of unpleasant odors and stagnant aromas. This arrangement, taking into account a safe distance, will ensure high-quality operation of your ventilation system.

To maximize the productivity of your kitchen hood, you need to know the minimum distance between appliances. The distance between the stove and the hood is often indicated in the instructions from the manufacturer and may vary depending on:

  • models of hood and hob;
  • type of surface (gas or electric stove);
  • type of hood (flat or dome).

The distance between the hood and the hob also depends on the type of device

Knowing the technical specifications of both essential kitchen appliances will help you hang the hood correctly.

Thanks to this gradation, you can easily use extreme boundaries to emphasize certain interior details. It is also worth installing the panel taking into account the growth of the hostess within the measured upper and lower points.

Often the installation height of the hood is not indicated by a specific prescription; such a distance is determined more by a range than by a specific number.

Gas stove: at what height to hang the hood

Gas is a blue fuel that from great-grandfather to grandfather warmed our relatives on harsh winter nights. Modern life dictates its own rules. Nowadays it is used not only as a heat source, but also as an excellent alternative to controlled fire. This is how gas stoves have become a convenient attribute in the kitchen over the last half century. When handled correctly and following safety precautions, a gas hob is completely safe to use and will not cause problems. But the use of this type of slab also requires appropriate care.

Cooking is a process that has the property of releasing a pleasant aroma. Often, due to the properties of physics, it spreads upward and left/right. To combat excessive odors in the home, humanity has come up with modern attribute household appliances - a hood that independently absorbs foreign odors during the cooking process. Often the hood is installed directly above the stove, taking into account the safe distance according to individual technical specifications selected model. But there are still standards for the location of household appliances in the kitchen. This is a very important feature to consider when locating new equipment.

Do not forget that the gas itself tends to emit a specific odor during combustion. Not only does it have unpleasant characteristics, but it also poses a threat to your health. You should not take the problem of natural gas poisoning lightly, because even small doses can become a serious reason for a sharp deterioration in your health.

Knowing clearly the answer to the question: at what height should you hang the hood above a gas stove, you can decide at what distance from each other they should be. For a gas hob, the norm is to position the hood at a height of 75-85 centimeters. If you prefer a beveled hood, then the distance will be 55–65 centimeters from the gas stove to the hood.

Distance between the hood and the stove (gas and electric)

Positioning the hood above the electrical surface

Regarding houses with a large number of floors, which are not equipped with gas to the best of their technical specifications, people have to adapt to the existing conditions. So residents face problems with heating, cooking and heating water. Gas surfaces in this case, they are replaced with ordinary, already familiar electric stoves.

Such “warm circles” are due to the fact that they relatively recently appeared in everyday life among the owners of our country. They are quite economical and compact. The loss of efficiency in it is greater compared to its gas counterpart. The need to use others kitchen appliances increases significantly. However, when there is little choice, we should be content with what we have.

Just like with a gas stove, cooking cannot happen without odors. To prevent your tablecloth, clothes, chairs and rooms adjacent to the kitchen from becoming saturated with the smell of borscht or pilaf, you should consider installing a powerful hood. It will draw foreign odors outside the apartment or house.

Such a household appliance has become an indispensable attribute of the modern kitchen. But it’s still worth remembering that safety precautions at this favorite family place for feasts and tea parties must be at their best. Special attention an oven and a hob are required.

So to understand what the distance should be above electric stove Before drawing, you must refer to the technical characteristics and features of the model.

Let's look at the two most common options.

  1. For most electric hobs, the distance from the electric stove to the hood should be approximately 65 to 75 centimeters.
  2. In case your kitchen furniture and the technique is more compatible with an inclined hood, then it is installed at a height of 35-45 centimeters from the previous one.

It is important to consider that the mentioned ten centimeter range in the exact location of the hood allows you to take into account individual characteristics interior, kitchen structure and location kitchen cabinets. The installed household appliance must be checked according to the technical specifications of the preferred model.

Make sure correct location before the installation process takes place. Then you can avoid unnecessary costs and ensure safety in the kitchen while preparing food.

Housewives cook up to 90% of all dishes on kitchen stoves. This creative and routine process is accompanied by the release of steam, pleasant (and sometimes not so pleasant) aromas, small particles of fat and harmful products, formed during the combustion process. All this saturates the surrounding space, and primarily the air in the kitchen. You can’t do without a ventilation device, but what should be the distance from the stove to the hood to ensure cleanliness in a small room?
Reply to this current issue you can find in today's article.

Optimal height values ​​for different units

The installation height of the hood above the tile is determined taking into account 2 components - the type of hob and design features equipment location for specific cuisine. It is necessary to understand that the height is never “tied” to the dimensions of the air intake, components or type of device.

The only exception to the rule is kitchens with low ceilings, where it is not possible to maintain the recommended distance between the hob and the hood.

Please note! Experts recommend adjusting the installation height of the fence structure within 10 cm of the nominal design value.

Horizontal solutions

It is possible to determine exactly at what height to install the hood only if you have information about the type of used kitchen stove. Based on this, the distance between the inflow and exhaust is selected. This type of equipment is installed taking into account a number of parameters (type of hob, performance of the intake unit, etc.).

The relationship between human height and device installation height

But what distance is considered optimal in terms of safety and efficiency?

The standard for each device is different, but there are accepted standards that are primarily advisory in nature:

  • the distance between the hood and the gas stove burners is from 65 to 85 cm;
  • minimum value of distance from hob electric type - 60 cm, and maximum - 80 cm.

The specified data is valid only for devices fixed strictly horizontally.

When installing inclined models, it is extremely important that the distance between the stove and the hood corresponds to the following values:

  • from 35 to 45 cm when working with an electric stove;
  • from 55 to 65 cm – for gas burners.

In conditions real kitchen It is customary to install ventilation units where operation will be not only efficient, but also convenient for the owner. The distances indicated above are experimentally established values ​​confirmed by years of practice. You can calculate them yourself, you just have to take into account a number of variables:

  • kitchen area;
  • planning features of the premises;
  • approximate area of ​​the cooking surface;
  • performance and type of hood;
  • growth of family members, housewives.

Please note! The exhaust unit is quite simply mounted above the electric stove, so the height can be increased without much difficulty, if necessary. But lowering equipment below the minimum level is strictly prohibited.

If you do not maintain the established distance and hang the unit too low, there is a high probability that the device will operate under constant heating conditions. And this is fraught with premature failure of the faithful assistant. In addition, if the hood is installed too low above the electric stove, it will simply be inconvenient to use.

Based on decades of practical operation, experts have formed their own recommendations regarding the height at which to hang the hood. There are unspoken rules for units placed above the base of a gas burner. They are indicated in the user instructions or installation recommendations that are attached to each model of the exhaust unit.

Here are just a few examples:

  1. 1. Products from Bosch are traditionally considered to be among the highest quality on the market. The average power of the units is 650 m3/h. It is better to hang a hood of the specified capacity at a distance of 65 cm from the surface of the burners.
  2. 2. Solutions produced by the Shindo brand are characterized by reliability and availability. For the most part we are talking about horizontal device average power. The average productivity of the devices is 450-500 m3/h. The kitchen hood is mounted at a height of 75 cm above the electric stove. Over open flame The device must not be located on the burner.
  3. 3. Products of the domestic brand Saturn cannot boast of high power, but at the same time, a productivity of 240-300 m3/h will be enough for the average housewife. The recommended distance to the hood is 75-80 cm from the burner.
  4. Which products to buy and from which brand is up to you to decide, but in terms of installation height, the units are almost identical. It should be noted that the distance from the surface of the gas stove to the hood is determined according to a number of important requirements:

  • ease of use;
  • leveling the likelihood of spontaneous combustion (especially if there are tables with other household devices nearby);
  • effective intake of dirty air over the stove or stove.

Taking into account the listed requirements, it can be argued that the safest and most acceptable distance from the hob to the hood is within 70-90 cm.

Results

Before purchasing an exhaust hood, we recommend that you check the dimensions of the slab (in particular its width), ceiling height and total area kitchens. Then, you should decide on the number of family members, the intensity and frequency of food preparation. The specified data will allow you to more competently select the optimal unit. And the hood height is indicated in the instructions for each specific model. With certain skills, installing it yourself will not be difficult.

So that the apartment or house has fresh and clean air, the kitchen should have very good ventilation. Natural ventilation cannot cope with the task of timely removal of odors during cooking, so a special forced ventilation device is hung above the stove - a kitchen hood. How to install the hood correctly, how to secure it and connect it to the ventilation system - more on that later.

Installing a hood in the kitchen is a wise decision

How to hang a hood over the stove

With the correct size, it is equal in width to or even slightly larger than the width of the slab. To install the hood correctly, you need to place it correctly and secure it. The electric hood is located exactly above the stove. The installation height depends on the type of hob:

  • The minimum permissible height for hanging a hood above a gas stove is 75 cm.
  • Above the electric value is slightly less - 65 cm minimum.

You determine the exact height yourself - based on the height of the housewife who will cook. The bottom edge of the hood should be slightly higher than her head. You shouldn’t hang it lower than the minimum distance, but you can hang it higher. But if you need to hang equipment higher than 90 cm from the level of the stove, you need a unit with increased power so that contaminated air is removed effectively.

The hood is attached depending on the type. Built-in - to a specially ordered cabinet size. Wall hung (flat) and dome (fireplace) - to the wall. The fireplace hoods themselves can consist of two parts - a unit with a motor and filters and a dome. Both parts are attached independently of each other, but so that their outputs coincide.

It is worth mentioning separately about island hoods. They are attached to the ceiling. The kit includes a suspension system and clear instructions on what to do and how to do it.

Installation stages

The entire installation and connection process can be divided into several stages:


If there is an outlet nearby, there will be no problems with connecting to electricity. The other steps are also not very complicated, but let’s look at them in more detail.

Attaching a wall or dome model to a wall

Although these two models differ in appearance, they are attached to the wall. They have four holes on the back wall of the case - two on the left, two on the right. Many manufacturers supply their products with a mounting template, which marks the location of the fasteners. All you need to do is lean the template against the wall and move the marks. If there is no template, measure the distance between the holes and transfer it to the wall. If you have an assistant, you can ask them to hold it at the selected height and make the marks yourself.

Then everything is simple: use a drill to make holes of the appropriate size, insert plastic plugs for the dowels, then hang the hood on the dowel-nails. Naturally, we check that the installed equipment is horizontal.

This method is good if the wall is smooth and nothing interferes. Often there is a gas pipe running next to the stove, which makes it impossible to hang the hood close to the wall. In this case, you can nail it to the wall wooden blocks, and attach the hood to the bars. This is a simple option, but not a very good one - the bars become covered with soot and are difficult to wash.

The second option to install the hood behind the pipes is to use a hairpin screw (the second name is a plumbing pin). They have a thread for screwing into the wall, a smooth part, which makes it possible to carry the hood some distance from the wall, and a smaller thread with two nuts, which will be used to secure the body. There are these studs different sizes, choose which one you need, but all nuts are made for a bit or an octagonal wrench.

This option for mounting the hood is universal, simple to implement, and reliable. It is also more convenient to clean - the metal is usually stainless, and it is easy to clean it from deposits.

Installing a built-in hood in a cabinet

The built-in hood is almost completely hidden in the cabinet made for it. It is attached in exactly the same way as described above - with screws, only they are screwed into the walls. Only in advance it is necessary to make holes for the air duct in the shelves located above. This is done after the hood has been purchased, since the location of the air outlet depends on the company and model.

If the cabinet is hanging, it is better to remove it. In the removed cabinet, install the hood in place, mark the location of the air outlet on the bottom shelf, and cut it out. To do this, it is easier to use a jigsaw and a file with fine teeth. The laminate file leaves almost no chips. If desired, you can seal the cut area with a plastic C-shaped furniture profile. They are rigid and flexible. The flexible one is easy to use - it bends at any angle, the hard ones will have to be heated before installation construction hairdryer. These profiles are “set” with glue; most often “liquid nails” are used. After installation in place, remove any remaining glue (with a damp, clean cloth) and fix it. masking tape to the shelf. We cut off the excess profile with a fine-tooth file and clean the cut. sandpaper with fine grain.

We make holes in the other shelves in the same way. By the way, they may no longer be round, but rectangular - it depends on the cross-section of the air duct you have chosen.

After this, all the shelves are installed in place, the cabinet is hung and secured. A built-in hood is attached to it with screws through holes in the body. Next is the process of connecting the air duct.

How to connect the hood to electricity

Since power consumption kitchen hoods rarely exceeds 1 kW, they can be plugged into regular sockets. It is desirable that they be grounded. This requirement must be met if you want the warranty to be valid.

If the wiring in the apartment is old, you can install the grounding or grounding wire yourself. Just don’t attach it to water supply or heating pipes. This threatens the possibility of electrical injury or even death for you, members of your group or neighbors.

To reach the grounding wire, on the shield, find a busbar with wires attached to it or a pipe to which it is welded/screwed stranded wire. You can also connect your own stranded wire to these devices (without discarding those that are already there). For it to work properly, the cross-section must be 2.5 mm, the conductor must be stranded copper, and a non-flammable sheath is desirable.

Some hoods come with a plug at the end. There are no problems with connecting such models - just plug into the outlet and that’s it. But there are models in which the cord ends with wires. This is not because of the greed of the manufacturer, but so that the consumer himself can decide how best to connect the equipment. If you want, you can connect a plug. This option is not suitable - take the terminal block and connect through it. Another option is Wago terminal blocks. You need to take three of them - according to the number of wires. In one terminal block, identical wires from the hood and from the panel are connected - phase to phase (the colors may be different here), zero (blue or dark blue) to zero, ground (yellow-green) to ground.

Air duct for kitchen hood

One of the stages of installing a hood is the selection and installation of air ducts. Air at room temperature is removed from the kitchen, therefore special requirements There are no connections to air ducts and you can use any. Three types are usually used:


There is also a difference between plastic and corrugated air duct - price. Polymer ones are more expensive. Despite this, if you have the opportunity to install a hood using PVC, install them. With an equal cross-section, they provide more efficient air removal and are also less noisy.

The cross-section of the pipes for the air duct is determined by the size of the outlet opening on the hood. In the case of rectangular pipes, an adapter is used.

Air duct sizes for hoods

Round ducts are available in three sizes: 100 mm, 125 mm and 150 mm. This is the diameter plastic pipes and corrugated sleeves. There are more sections of flat air ducts and they are presented in the table.

How to choose a size? In the case of round pipes their diameter must match the diameter of the hood outlet. It is very undesirable to install an adapter at the outlet and then use an air duct of a smaller diameter - this will reduce the speed of air purification. And even if the hood is very powerful, it will not cope with air purification.

With the choice of the cross-section of a rectangular air duct - its cross-sectional area should not be less area cross-section of the outlet pipe. And the connection occurs through a suitable adapter.

How to attach corrugation to the hood and ventilation

If you decide to install a hood and use aluminum corrugation for the air duct, you will need to think about how to attach it to the body and to the ventilation. To do this, you will need clamps of the appropriate size. They can be metal or plastic.

To connect the hood to the ventilation system you will also need a special ventilation grille. It has a hole in the upper part for connecting the air duct pipe. There are holes in the lower part to remove air from the kitchen using natural circulation when the hood is not working.

A grate with a protrusion is suitable for attaching the corrugation - around the hole there is a side of several centimeters, onto which the corrugation is placed, after which it is secured using a clamp of a suitable size.

The corrugated air duct is attached to the hood using the same principle. It has a protrusion on which the corrugation is put. The connection is tightened using a clamp.

How to attach an air duct to walls

For plastic air ducts there are special fastenings in the form of latches. They are first mounted on the wall using dowels. The installation step depends on the curvature of the route, but on average, 1 fastening per 50-60 cm is sufficient. Pipes are inserted into these latches during installation with little effort.

If the air duct needs to be fixed to the ceiling, you can use the same fastenings. But if you need to maintain a certain distance from the ceiling, this type of installation will not work. In such cases, take perforated plasterboard hangers, attach them to the ceiling, and then use small PVC screws to attach an exhaust duct to them.

Corrugated air ducts are attached to the walls using clamps or large plastic ties. If necessary, they are also mounted to the ceiling using perforated aluminum hangers.

Where and how to remove the air duct

Most often, the air duct from the kitchen hood is connected to a ventilation hole through which natural ventilation occurs (due to draft). This is incorrect, since in this case most of the grille is closed by the air duct, and air exchange through the remaining accessible holes will be clearly insufficient.

Correctly connect the air duct to a separate ventilation duct. In this case, the same grille as in the photo above is installed on the hole.

If there is no separate ventilation duct, but there is one nearby outer wall, you can take the pipe outside by placing a grate outside. These are two ways to have normal ventilation and ensure normal operation of the hood.

How to take it outside

To install the hood and lead the air duct into the wall, you need to make a hole in it. And this is the only difficulty. Next, an air duct is inserted into this hole and sealed with mortar. From the outside, the hole is covered with a grill to prevent debris from getting in and birds and small animals from settling in.

To prevent outside air from blowing into the room, install a check valve (in the figure above it is indicated by an oblique line). By the way, it is advisable to install it when connecting the air duct to the ventilation system - so that odors from the pipes do not enter the room.

The check or anti-return air valve is a lightweight plastic or metal plate. It is movably attached in two places to the pipe - at the top and bottom, the petals are supported by a weak spring. While the hood is not working, the valve blocks access to air from outside. When the hood is turned on, the air flow bends the plate forward, pressing the spring. As soon as the hood is turned off, the plate returns to its place using springs. If you install a hood without this valve, the kitchen may be too cold in winter - outside air will be able to get into the room without any problems.

So that the hood does not interfere with natural ventilation in the kitchen

Using a tee and check valve By the way, you can install the hood so that it does not interfere natural ventilation in the kitchen. You will need a special ventilation grille for connecting hoods, a check valve and a tee. A tee is attached to the ventilation grille, an air duct from the hood is connected to its lower entrance, and a check valve is installed on the free outlet, only so that the petals are locked when air passes from the pipe (pictured below).

How does such a system work? When the hood is turned off, the petals of the check valve are bent, air from the kitchen enters the ventilation duct through the grille and the open outlet of the tee. When the hood is turned on, the air flow from it unfolds the valve plate, and air flows into the ventilation system. When the hood is turned off, the springs again open air access through the tee.

Externally, such a system does not look very attractive and will have to be disguised in some way. But this the only way connect the hood to the only existing ventilation outlet and do not reduce air exchange.

For any modern kitchen there is a place for a ventilation device. The distance from the stove to the hood determines the effective operation of this structure.

Types of exhaust hoods and their purpose

The hood protects kitchen space and furniture from contamination with tiny particles of fat and impregnation with a mixture of various odors. No one will feel good about the curtains or soft upholstery chairs create an unpleasant aroma, which can also penetrate into other living rooms.

All devices according to the principle of operation are divided into:

  • circulating (with built-in filter);
  • hoods with an air duct (connected to the ventilation system).

In circulation models, the air is purified using a carbon filter and returned to the kitchen. Such hoods are effective only in small spaces, where it is not possible to install an air duct, and the distance between the stove and the hood should be small.

The second type is characterized by more quality work, since the air is completely removed from the room. Installed in large rooms.

Types of exhaust devices:

Where should the hood be located?

When purchasing a hood, it always comes with instructions for use, which indicate where and at what distance from the stove the device should be located. The exhaust structure can be built into a wall cabinet, or it can be located under it, the main thing is that its size matches the size of the hob, and it hangs exactly above the stove. Also, even before purchasing a hood, you should consult with specialists about its power. For example, a small appliance will not fit in a large kitchen space, but small kitchen there is no need to install a very powerful unit.

How to determine the optimal distance from the hob to the hood?

The distance from the stove to the hood is determined by the established standard. If there is an electric stove in the kitchen, then the exhaust hatch should be located no lower than 65-75 cm from it, and if the hood is above a gas stove, the distance between them is 75-85 cm. In the case where the device has an inclined surface, the installation parameters change slightly :

  • the distance from the gas stove to the hood is reduced to 55-65 cm;
  • the height above the electric hob is reduced to 35-45 cm.

You also need to take into account the height of the person who will be most likely to be near the stove, and the overall interior of the kitchen.

Why is it necessary to comply with the standards for installing an exhaust hatch?

These are the optimal parameters for installing the hood, facilitating its efficient work. It is not recommended to reduce or increase them. If the device is located high, its air absorption capacity may not be enough, then odors along with fat droplets will quickly spread everywhere. Setting the hood low can interfere with the cooking process. This will not only make it inconvenient to approach a gas/electric stove and place high pots, but there is a risk of the structure heating up, igniting it and damaging the paintwork.

Thus, the question of what distance from the stove to the hood should be can be answered unambiguously: 75-85 cm in the case of a gas stove, and 65-75 cm above an electric stove.

Factors influencing the location of the exhaust structure

When purchasing and subsequent installation of a hood, the following factors should be taken into account:

  1. Hob type. Do you need to calculate the distance between the hood and the gas stove or electric stove?
  2. Declared power of the device.
  3. Kitchen design/interior.
  4. Compliance with the ventilation hatch installation standards specified in the technical passport.

Compliance with these conditions for installation and operation of ventilation equipment will allow you to use the device as efficiently as possible and protect the kitchen from unpleasant odor and fat.

Rules for installing ventilation equipment

Optimal performance of the device depends on the following factors and installation rules:

  • the device must comply. Then all the hot, contaminated air flow will be completely absorbed by the hood and discharged outside, or cleaned through a filter and fed back into the kitchen. Standard sizes the device ranges from 60 to 90 cm.
  • Competently installed hood above the stove. The distance from the device to the stove should not contradict the standards fire safety and depends on the type of plate. The required distance from the stove to the hood is always indicated in the technical data sheet of the device.
  • Connecting the device to the network.
  • Installation of air exhaust pipes, if required by the design of the exhaust hood.

It is better to entrust the installation of ventilation equipment to professionals. But for those who are confident in their abilities, it will not be difficult to hang the device with their own hands.

Installing a hood with a circulation type of operation is not difficult. First you need to measure its height and mark it with control points. Then you should drill holes in the wall for the fasteners. Next, the device is mounted to the wall or to wall cabinets using self-tapping screws and special hooks included in the kit.

Hoods of another type of air purification are installed in the same way as circulation hoods. Only here you need to attach the air duct pipe to the umbrella body. The pipe can be plastic or foil.

Upon completion of installation of the equipment, it is necessary to carry out a control check of its operation (mainly for the second type of model). If the hood does not function or is too noisy, you should once again check all the connections between the device and the ventilation pipes and their integrity.

Air duct installation

The air duct should not have many bends, as this will significantly complicate the removal of contaminated air. It is desirable that the pipes are short, straight and contain a small number of elbows. Changing the direction of the air duct is carried out in a place with a large bend radius. The diameter of the outlet pipe must correspond to the hole in the design of the exhaust device. It is not recommended to deliberately narrow the holes and install additional connecting elements between them. This impedes the free flow of air, and accordingly, a large load is created on the working motor of the hood. Excessive noise may occur.

Most often, these structures are made of thick foil and then masked with PVC boxes/plasterboard so as not to disturb the interior of the room.

Where should the outlet for the hood be located?

The electrical outlet for connecting the exhaust hatch is usually installed at a height of 2-2.5 m above the floor level. Thus, it should be located higher wall cabinets by 10-20 cm. It is also shifted to the left or right of the air duct by 15-20 cm.


Conclusion

The article above discussed the types ventilation devices, at what distance from the stove to hang the hood, methods of air purification.

At proper installation The exhaust device will ensure clean air in the room and the cleanliness of surrounding interior items. When choosing and purchasing an umbrella, it is necessary to take into account the correspondence of its power to the cubic capacity of the kitchen, appearance, as well as methods of air purification: complete exhaust through an air duct or circulation of purified flows.

The main points for installing a specific appliance model and the distance from the stove to the hood are described in the instructions. Generally accepted standards determining the installation height of the device: from 75 to 85 cm for gas stoves; from 65 to 75 cm for installation above electric stoves.
