How to install a hood over a gas stove. How to properly install a hood over a gas stove. Exhaust equipment installation options

Proper organization of ventilation in the house allows you to create an optimal microclimate without foreign odors and excessive humidity. One of the most important components of the ventilation system is kitchen hood . It is she who is responsible for removing food odors and steam from boiling pots. We will tell you in this article how to install a hood over a gas stove and whether there are any standards for its installation.

Features of kitchen ventilation

Many citizens of our country believe that if there is a window in the kitchen of a private house, this is enough for effective ventilation and removal of odors from cooking food. Experts say that this opinion is wrong; any kitchen needs a hood. The window opening does not provide effective removal of contaminated air, because it cannot forcibly capture waste air masses and remove them from the room. As a result, despite the apparent cleanliness of the air in a private house or apartment, owners find dirt and grease on cabinets, dishes, walls and ceilings. These particles indicate air pollution, and therefore a regular harmful effect on the human body.

Hood over gas stove It will not only rid your home of food odors, but will also eliminate unburnt fuel residues, smoke, fumes and suspended oil particles. Conventional hoods for gas stoves consist of an air intake, filter elements, and forced ventilation devices. Air masses can be purified flow or circulation method.

Flow structures connected to a central ventilation system or have an outlet pipe outside the house. The principle of their operation is to capture waste air masses and bring them outside. For this system to operate effectively, it is necessary to ensure an influx of fresh air from outside.
Circulation designs work on a different principle. They also forcefully capture exhaust air. After this, the air masses pass through several filters and return to the kitchen space. Such hoods do not require connection to the ventilation system and the laying of additional pipe networks. Disadvantages include the duration of air treatment and the possibility of incomplete cleaning if the filters are dirty.

Which hood is better? Professionals advise purchasing flow-through devices, but if it is not possible to install air outflow and inflow, circulation models are a good option for use in a private home.

How to choose a hood

Today, the choice of kitchen appliances for air purification is huge. By installation method types of hoods are as follows:

When planning the purchase of ventilation equipment, you need to know how choose the right hood for a gas stove so that ventilation can cope with basic tasks.

Firstly, need to be selected hood size in accordance with the dimensions of the stove surface, that is, the width of the hood must be no less than the width of the stove for its full operation.

Secondly , determine hood location.

Third, when choosing a device, pay attention to its technical features . The square footage of the area to be cleaned should correspond to your kitchen. For example, circulation hoods are recommended for small rooms with an area of ​​no more than 6 square meters. m.

Many users are interested in how to choose a ventilation device based on power based on the number of people living in the house. In fact, there is such a formula. To calculate, you need to multiply the number of people by the air consumption for each family member . The consumption rate for 1 person is 60 cubic meters per hour. Thus, the hood capacity for a family of 4 people should be at least 240 cubic meters per hour. However, for an accurate calculation, you also need to take into account the air exchange rate, the area of ​​the kitchen and the height of the ceilings.

There is also a rule by which the required hood power is calculated: multiply the area of ​​the room by the height and multiply the resulting volume by a factor of 12.

Power table for kitchen fans (m3 per hour)

You can choose a hood according to your budget. There are many manufacturers of kitchen appliances on the market and choosing an appliance in the desired price range is not difficult.

Installation secrets

If you do not want to hire professional installers, but want to do all the installation work yourself, you need to know how to properly install a hood over a gas stove.

It must be taken into account that Each hood has its own installation recommendations. They are described in the instructions that come with the device. Before installing the device yourself, carefully read the manufacturer’s recommendations and strictly follow these standards during installation.

Installation steps

Installing a hood over a gas stove has its own nuances.

1. First of all, when hanging the hood, you need to decide on the installation height. The height of the hood above the gas stove is an important parameter that must be observed in order for the device to perform its functions. We measure the required height with a regular tape measure. Next, using a level, draw a straight line to guide you when drilling holes.
2. Using a tape measure, measure the distance between the fixtures of the device. We transfer these dimensions to the previously outlined straight line. Next, drill holes at these points. You need to insert plastic clips into them that will securely hold the mount. Screw on the hood.
3. For a built-in hood, you need to make a cabinet of suitable size. This is done when ordering kitchen furniture, even at the interior planning stage. In this case, the dimensions of the hood need to be known in advance.

How to hang a flow hood?

If you have a flow-type device, you first need to install a corrugation for air outflow, and then hang the hood. The corrugation must be connected to the ventilation system or taken outside the house. When installing the outlet hose, you need to ensure that there are no gaps at the junction with the hood and the ventilation pipe, and that the corrugation is attached tightly.

IMPORTANT! The diameter of the corrugation must correspond to the diameter of the air intake in the wall. This will increase the efficiency of the device and ensure quick air purification in the room.

When installing a flow hood, users are faced with one problem - the unaesthetic appearance of the corrugation. A really long outlet sleeve can ruin any interior with its unsightliness. But there is a way out! Kitchen appliance manufacturers offer special boxes , which reliably hide all unsightly ventilation elements from prying eyes. Ventilation ducts will not only hide the corrugation, but will also help decorate the kitchen thanks to various design solutions.
After installation, you need to test the operation of the device. To do this, place a pan of boiling water on the stove and turn on the hood. If the steam immediately enters the air intake, you have done everything correctly and your kitchen is reliably protected from foreign odors and excess humidity.

Service maintenance

For the ventilation system in the kitchen to function properly, the hood must be serviced promptly and correctly. Failure to comply with maintenance standards can lead to a decrease in the efficiency of the device, and therefore to poor quality air purification. Over time, without maintenance, the hood may completely fail, which will entail additional costs.
When installing a circulation hood in a kitchen with a gas stove, you need to take care timely replacement of filters. The service life of the carbon filter is indicated in the device instructions. In these models, it is the carbon filter that is the main element of air purification, and if the components are not replaced in a timely manner, the device will simply cease to perform its functions.

The second rule of maintenance is keeping the device clean . Kitchens with a gas stove are characterized by increased air pollution from waste combustion products. The hood must be washed regularly, because grease and dirt constantly collect on its body. Failure to maintain proper hygiene of the unit may cause the air intake openings to become clogged and the equipment to be ineffective.

Check the pipe attachment points regularly. When cracks appear, the efficiency of the device decreases. Also make sure that the corrugation is not twisted or pinched.

Which hood to choose for a gas stove is up to you. But remember that only if you follow the installation rules and maintenance recommendations, will your ventilation effectively purify the air in the kitchen for many years.

There are two types of air exchange in the kitchen with a gas stove - general and local. An exhaust device directly above the hob ensures not only the removal of gases and odors from the entire living space, but also necessarily in order to comply with safety measures and comfortable living. To do this, you need to know not only how to calculate the required geometric parameters, but also how to correctly install the hood over a gas stove.

Documentary base

• The operation of gas equipment and its maintenance require compliance with approved construction rules and regulations. These include:
• regarding the requirements for mandatory forced ventilation of such premises - SNiP 2.04.05-91;
• standards for the hourly volume of exhaust air removed - at least 90 cubic meters for 4-burner stoves - SNiP 2.08.01-89;
• the required performance of the ventilation unit in the hood above the gas stove is at least 200 m3/h (GOST 26813-99).

These and other documents provide answers to emerging questions on the topic: how to install a hood over the stove?

In operating mode, the hood must localize the spread of odors and fumes, drawing them into the air duct. At the same time, the distance from the surface of the stove to the edge of the exhaust hood should be optimal to allow free work at the stove.

Performance calculation formula

Installing a hood above a gas stove will be justified if it completely ensures the removal of exhaust air. The required power of the device is determined by the formula:

N – required power,

Q is the volume of circulated air in the kitchen.

In turn, the volume is determined as follows:

where: a, h, b – length, height and width of the kitchen space, respectively.

According to the standards, the height of the exhaust device is selected based on:

• power of the exhaust device;
• the height of a person at the stove;
• architectural features of the room.

This explains the size range: with a straight hood, its height above the gas stove is selected from 75-85 cm, the inclined model of the hood in the lower part is 55-65 cm. In this case, the width of the working part of the hood structure must be no less than the same size as the hob or even overlap the width of the slab. Therefore, first they buy a gas stove, and only then select a hood. Standard dimensions are usually indicated in the operating instructions. They can be changed to adjust a person’s height, but not downward.

Attention! All devices for purifying air from smoke and combustion products must have a certificate for installation in the kitchen.

When connecting the system to the ventilation hose, you should avoid its bends or make sure that there are as few of them as possible, and the outlet itself is of a minimum length. The air vent is composed of short and straight sections. In situations requiring a change in its cross-section, clamp adapters are used.

Types of hoods and operating principles

Local hood - turns on during cooking

There are two options:

1. The exhaust device works to remove unnecessary vapors, fats, and odors along with the air. During recirculation, the flow passing through the filters is cleaned and returned back.
2. The hood is connected to the ventilation hose. Dirty air masses, being captured, are immediately transported from the premises. As an option - direct output through the wall directly to the street.

Parameters for selecting a hood

The main indicator of the exhaust device is the maximum permissible volume of air removed per unit of time. The capacity of the hood is indicated in its passport.

Installing a hood above the stove takes into account:

• hob width;
• dimensions (area) of the kitchen;
• ceiling height;
• number of household members living;
• frequency of food preparation.

Based on this indicator, a model of the required performance is selected and the height of its suspension is determined. It is better to purchase a model with several adjustable power modes.

Hood installation

Preparation

Before proceeding with installation, choose the correct location for the equipment - gas stove + hood. The photo shows an electric stove - the recommendations are also relevant for gas objects.

Before installing a hood over a gas stove, you need to first prepare the room.

• Mark on the kitchen plan the location of all communications, as well as installed appliances, if the installation is carried out in an already used room.
• The energy dependence of the hood requires the presence of an outlet (but not above the stove!) with 220 V connected. A model with an automatic switch is preferable: it will always turn off in time if a short circuit or fire occurs. If the kitchen is not equipped with a grounded socket, the rules for installing a hood over a gas stove require that a separate RCD (16 A) be provided in the electrical panel. Connect to the network a line of three wires “zero”, “phase”, “ground” in yellow insulation with a green stripe running along it.
• The value between the exhaust device (lower edge) and the surface of the stove (burner) is measured.
• The completeness of the package is checked for the presence of the necessary fasteners, hooks, dowels, etc.
• The location for attaching the structure is marked.

Installation

• the air duct is assembled. It can be with a square or round cross-section. Standard option - size 130x130 mm It is better to choose a plastic design with smooth internal surfaces. Its diameter should be the same along its entire length, correspond to the cross-section of the ventilation hole and, preferably, have a check valve.
• Using a hammer drill, holes are drilled for the hood clamps.
• The screws are screwed in.
• Using a level, check the horizontal installation.
• The hood is hung (without a box).
• Connects to the exhaust pipe connected to the duct.
• The hood is connected to an electrical outlet. If the cord is missing or short, an autonomous line is drawn from the panel or diverted from the outlet closest to the hood. Making twists insulated with insulating tape in places where the missing part of the cord is added is strictly prohibited.
• A test run of the technical device is carried out in all modes.
• During normal operation, the final stage is to secure the box.

Exhaust equipment installation options

According to installation design, exhaust devices are:

• built-in type - the entire installation is hidden in a hanging cabinet;
• fireplace and dome type - the structures are fixed on the wall;
• island model - mounted on the ceiling;
• corner hood - placed in the corner;
• flat model - involves two planes of fixation: from the back - to the wall, from above - in the hanging cabinet.

Any of the models provides a certain type of filter elements that absorb strong odors, grease and other secretions.

Used as filters

• Grease traps are installed only in kitchens with a ventilation shaft.
• Carbon filters are elements of modern treatment systems with recirculation mode of operation.

Even if you follow the rules for installing the exhaust system and operating it, the efficiency will be reduced if preventive maintenance is not carried out on time: clean surfaces, change filters. Thus, creating the conditions necessary for a safe and comfortable stay in the kitchen is not difficult at all. Various methods are used for this. But it is the forced system with local exhaust above the stove that is considered the most optimal and common option.

After purchasing a kitchen air exchange device, a logical question arises - how to install a hood over a gas stove in a private house with your own hands?

The relevance of the issue is due primarily to the fact that the modern kitchen is overflowing with household appliances. It is difficult to imagine a comfortable life without a microwave, refrigerator, multicooker or stove. The above list can be supplemented with a hood. How to install a hood and install this device will be discussed in today’s material.

Is a hood needed in a kitchen with a gas and electric stove?

Many owners are interested in whether a kitchen hood with a gas stove (electric stove) is necessary in principle. The absence of an exhaust unit leads to several negative points.

The most unpleasant ones are that a huge amount of steam and smoke accumulates in a small room. With prolonged exposure, an increase in humidity is observed, which negatively affects the integrity of the facing materials. During the cooking process, residual fumes and fat particles must be removed.

Types of devices

Before installing a hood, you need to decide on the specific type of household appliance. The most popular types of devices today are:

• island;
• fireplace;
• corner;
• built-in;
• filtering.

Exhaust devices are equipped with different types of filters:

• Hoods for gas stoves with carbon filters. They are distinguished by the effective elimination of unpleasant odors and fatty particles. They work primarily on the principle of air recirculation.
• Devices with a metal cleaning grid (grease trap). Suitable for gas stoves and kitchens that have access to a ventilation shaft. If it is missing, installation is not recommended. Their main advantage is the high-quality absorption of fumes and unpleasant odors. Equipped with aluminum filters.

If the kitchen hood is installed correctly and professionally, the air will be effectively cleaned of fumes through a filtration mechanism and then redirected back into the room. As for units equipped with grease traps, they do not filter contaminated oxygen, but remove it outside.

There are also universal models that provide not only filtration, but also air removal. It all depends on the specific requirements and criteria.

Some apartments do not allow you to connect an exhaust hood to the ventilation system. For such cases, it is necessary to install household devices that operate on the recirculation principle (air filtration and redirection back into the room). What system is needed in each specific case is up to the owners to decide, but we recommend purchasing units with carbon filters.

Efficiency and performance of the hood

A modern hood over a gas stove is capable of providing different levels of air exchange (the value can vary between 200-1400 cubic meters per hour). But it is not always worth purchasing hoods with maximum power. An air pumping speed of 500 m3/hour is considered sufficient.

The calculated efficiency value is multiplied by the volume of the room and by 10. The final result is multiplied by 1.3 (this is a small reserve that every household appliance should have). At the output, we obtain a performance value sufficient to purify the air at medium loads (the device does not operate at maximum speed and unpleasant noise does not occur). This efficiency value will be optimal.

In the device passport it is customary to indicate the capacity of vapor removal into the ventilation air duct. If the kitchen appliance operates in 2 modes, then the power of the second will be 60% of the passport data (up to 40% is lost when passing through the filter).

There are no absolutely silent hoods. But you can always choose an option with optimal noise and performance values. Acceptable level is 36 dB during operation. Systems powered by an electric motor installed in a soundproof plastic box can boast such values.

How to install a hood in a closet

To ensure that installing a hood over a gas stove causes the owner a minimum of hassle, several important points should be taken into account. The individual characteristics of a specific model of kitchen appliance, the type of filters, the location of the ventilation shaft, etc. are taken into account.

Installation of a firecracker (anti-return mechanism)

Let us dwell in more detail on the features of installing an air cracker. First of all, it is worth installing an aluminum or galvanized product. A wide range of such solutions are now on sale. It is mounted directly in front of the ventilation shaft.

To ensure maximum convenience, it is better to install a hood above a gas stove in a private house in a cabinet located above the base of the hob. Installing the housing into a kitchen unit does not cause any difficulties. Then the holes and cracks are filled with polyurethane foam, thanks to which the device is fixed very securely. Due to this, the resonance of the household appliance during its operation is leveled out.

It is not recommended to install the firecracker immediately. First, you should place the exhaust device and mark the places where the holes will be located. For convenience, the cabinet is first removed, and the necessary cuts and shapes are made inside.

Cutting inside the kitchen unit will be simplified if the diameter of the hole is marked with several through holes (in a circle). After this, a jigsaw is inserted and a hole is made with its help. They should be on every shelf, if there are any in the closet. This will simplify the installation of the air duct.

Duct installation

Installation of the air duct is carried out in the following sequence:

During installation, it is necessary to minimize the number of bends of the corrugation or plastic pipe. This will ensure good traction since cornering reduces power by an average of 10% in each knee.

How to install a hood: standard installation sequence

The owners are interested in: how to properly install a hood over a gas stove in cases where it is impossible to place the device above the hob in the kitchen unit? Obviously, it has long been not always practical to place a unit in a furniture structure, since under the influence of humidity these accessories deteriorate and lose their original aesthetic appearance.

Almost all modern wall cabinets are narrow, which excludes the possibility of placing wide devices in them. The recommended height of the hood above the gas stove is 650-750 mm.

Installation is carried out in several stages:

1. Using metal corners, a rectangular structure is formed. This frame is used to support the body of the exhaust device.
2. Self-tapping screws are ideally suited as fasteners for fixing to the wall.
3. The hood is connected to the electrical network.

Gas workers emphasize the need to ground fans so that residual voltage is discharged into the external space. The distance from the gas stove to the hood is indicated in the passport data for each unit model.

Important points

Experts highlight several important aspects that deserve attention during the installation of the device.

1. Filters are cleaned or replaced every 2-3 months (taking into account the intensity of use). Large amounts of fat and residual substances can cause the structure to catch fire.
2. The installation height of the hood above the gas stove is 65-75 cm. If you install the device too low, it will not cope with the load and the increased temperature, which can lead to failure of the unit.
3. The “golden” rule for selecting exhaust hoods is that the hood should be the same.
4. The kitchen appliance is connected to an electrical network independent from the main part of the house.

During installation, observe safety precautions. Preventive cleaning of the hood from burning is carried out once every 2 quarters, under medium loads. Knowing at what height it is better to mount the device, you can save a small amount on the services of specialists.

It is difficult to imagine a modern kitchen without such a household appliance as a hood. Its main purpose is to remove contaminated air masses and unpleasant odors outside the occupied space. Today, no one counts on ventilation in the form of boxes, because over time the channels become dirty and narrowed, as a result of which their efficiency greatly decreases. Therefore, a hood installed above a gas stove is an ideal solution for removing contaminants coming from the stove.

The classification of exhaust devices is based on the principles of operation and methods of installation of the devices. There are two positions that differ from each other in the operating principle of the device. Accordingly, their technical component differs.

• Flow hoods. A simple model with a fan installed. Their main task is to remove polluted air to the street or into the ventilation system of the house.
• Recirculating hoods. They are designed with filters through which polluted air is driven through using a fan. It is cleaned and returned back to the premises. In this case, no connections to the street or ventilation ducts are required. Therefore, installing such a hood above the stove is the simplest.

Recirculating hoods, in turn, are represented by a wide range of models:

• Wall-mounted - they are mounted to the wall above the stove. The design of the device has mounting holes through which holes are made in the wall. Fastening is most often done with metal dowels. This type of hood resembles a dome in its shape, which is why they are also called dome or fireplace hoods.
• Hanging. These are the most common models because they are attached to the bottom surface of a wall cabinet that is hung above the cooktop. Mounting method: bolted connection to the cabinet. That is, before hanging the cabinet and the hood, you should place them on the table next to each other and mark the joints. Then, through holes are made in the lower plane of the cabinet using a drill and a drill bit. And then you can do it in different ways: install and secure the cabinet on the wall, and then attach the hood to it with bolts, or make the connection on the table, and then hang the entire structure on the wall.
• Built-in. Today these models are very popular. This is due to the fact that you do not have to select the device by color and shape, because it will be hidden in a wall cabinet specially made for it. Only the control panel will be visible. Therefore, before installing a hood over a gas stove, you need to take its dimensions and make a cabinet for them. Or, conversely, select the right device to fit the size of the cabinet. However, before this you will have to accurately calculate its power so that it matches the dimensions of the kitchen appliance. As for installation, there are no difficulties here. The hood is simply installed in the cabinet and closed with a door.
• Inclined. This type of hood is gradually gaining popularity due to the unusual installation. The device consists of two parts: a hood and a mounting panel, which is fixed to the wall above the gas stove. The equipment is made as follows: a horizontal line is applied to the wall above the slab, then the mounting locations for the holes are marked, after which the panel is applied to the drawn line, and an exhaust device is inserted into it.
• Island. Installing such a hood over a gas stove is a special case. Firstly, the device received its name only because it is installed above the stove, which is part of the kitchen island. Secondly, the hood is attached to the ceiling using special collets and pins. Installation occurs in this way: collets are attached to the ceiling, pins are hung on them, which are attached to the first ones through a thread. The studs are attached to the hood in the same way. Then the resulting fastening system is closed with a box. If a recirculating hood model is installed above the island, then the decorative box does not need to be used. This design is secured with cables that will be visible. There are designs that are fastened using a combined method, that is, both pins with collets and cables are used.
• Angular. These are ordinary wall-mounted units that are attached directly to the wall. Only they are mounted not to one wall, but to two adjacent to each other, that is, to the corner of the room.

Ventilation duct installation

A ventilation duct is a part of flow devices that are made of plastic in the form of round or rectangular pipes, or in the form of a corrugated pipe.

In hoods, the outlet pipe has a round cross-section, so it is ideal if the ventilation duct is round. Today, manufacturers offer various adapters: from round to rectangular, from one diameter to another. That is, it became possible to use any pipes, regardless of their shape and size. The main thing is to choose the adapter accurately.

The pipe sections are connected to each other through double-sided couplings or bends. Typically, pipes have a slightly smaller diameter than fittings, so they fit easily into each other. At the same time, the joint is completely sealed, which is very important in the ventilation system. A corrugated pipe is a single channel that can be bent if necessary. On the hood it is also connected through an adapter. Fastening is done with plastic or metal clamps.

Technical indicators

To accurately answer the question of how to properly install a hood over a gas stove, you should additionally identify two more positions:

1. Hood installation height. As for the gas stove, this size should be 85 centimeters.
2. Device power. It is calculated using a formula that includes the volume of the room (kitchen) and air circulation. The first is the floor area multiplied by the height of the ceilings. The second is a standard value, which is indicated by sanitary standards. For the kitchen this figure is 12 m³/hour. But for the room where the gas stove is installed, this coefficient is 15-20 m³/hour, depending on the intensity of use of the device.

The functionality of home exhaust ventilation ducts almost always left much to be desired. They did not cope with their main task - extracting waste air and unpleasant odors from the kitchen area. That is why such useful and necessary devices as hoods were subsequently invented, which were much more effective than ducts. When planning to install new kitchen equipment, many people wonder at what height to hang the hood? Does it matter. The performance and quality of its operation often depend on the height at which the device is mounted.

Design of a standard hood

You can more accurately imagine the location of the hood if you understand at least a little about its structure. A standard hood consists of the following elements:

• Steel body;
• Engine;
• Engine impeller;
• Filter;
• Control device.

You can set the operating modes for the hood. There are only two of them - filtration (recirculation) and air exhaust into the ventilation duct.

Types of hoods

There are four main types of kitchen hoods:

1. Wall-mounted fume hoods;
2. Island hoods;
3. Built-in structures;
4. Desktop devices.

The first type looks like an umbrella with a pipe, which is mounted on the wall where it is clearly visible. Therefore, its design should suit the interior of the kitchen. Outwardly, it is very similar to a chimney from a fireplace.

Island-type devices are most often attached to the ceiling. They are used if the kitchen interior is designed so that the stove is located in the center of the room. This model operates only in one mode, based on the air exhaust principle.

Built-in appliances are placed inside cabinets. They are hidden from view, so they do not need to be trimmed too carefully. Their technical characteristics are no worse than those of other models, but they cost a little less.

Tabletop structures are built into the hob itself. They look like another panel section. Due to the fact that this model is located in close proximity to the source of dirty air, the quality of cleaning is usually high.

How to determine the mounting height of the hood

Very often, in order to determine the optimal mounting height for the hood, it is enough to look at the instructions for this device model. Usually, it is not a specific distance that is indicated, but a range within which kitchen exhaust equipment should be placed.

In this case, you should take into account such important facts as the height of the owner of the apartment and the features of the kitchen interior. But even if the instructions are lost, there is another way out. There are standards that make it possible to more clearly determine at what height a kitchen hood should be placed above the hob or stove.

It is necessary to take into account the type of hob; each type has its own measurements. So, at what height is it recommended to hang the hood:

• It is placed above the gas stove at a height of 75-85 cm,
• Above electric stoves - at a height of 65-75 cm.

If you choose an inclined model, then the distance from its bottom to the hob should be approximately 55-65 cm for gas stoves, and about 35-45 cm for electric stoves.

The height may vary, but only within the specified 10 cm, and also depending on the power of the particular model and its technical characteristics. These limitations should not be neglected; not only the quality of the equipment’s performance depends on these indicators, but also the safety of the work, in particular fire safety.

Basic rules for installing a hood

Better operation of the device is only possible if the hood completely covers the surface of the stove. In this case, polluted air will be almost completely absorbed, and its leakage will be minimal. This is the main reason why buyers prefer models with a wider umbrella, from 60 to 90 cm. This size corresponds to the size of a standard stove or panel.

The height of the exhaust hood is determined in accordance with ergonomic rules and fire safety standards. The shorter the distance from the umbrella to the hob, the better the absorption of kitchen fumes and bad odors. But at the same time, the height should not be too low, otherwise there is a high risk of damage to the ventilation system. This can happen due to overheating or even combustion of the greasy film that forms on the surface of the filter.

Therefore, for safety reasons, the minimum distance from the stove to the umbrella should be about 50-65 cm. The values ​​may vary slightly. Often the optimal installation height for the hood is indicated in the technical data sheet. For ergonomic reasons, it should be positioned so as not to interfere with food preparation.

Hood installation options

There are several installation methods. The first involves placing an exhaust hood inside a hanging cabinet that does not have a bottom. An exhaust device is attached to the central shelf. In the same shelf, as well as in the ceiling of the cabinet, holes are made for the hose outlet.

One end of the hose is attached to the hood, and the other is inserted into the holes and out into the ventilation duct. In filtration mode, the hose is cut off as it exits the hole in the ceiling of the locker.

The built-in type of hood is mounted according to the diagram presented in the instructions for it. The model is designed for installation in a box or in a hanging cabinet.

Hood attached to the bottom of the cabinet

A hole is made for the hose in the bottom of the kitchen cabinet, as well as in the ceiling shelf. To carry out the discharge into the ventilation, the hose is brought to the very opening of the ventilation vent.

For filtration mode, it is cut off at the exit from the hole in the ceiling shelf of the cabinet. The hood is hidden behind a panel; the material for it is identical to that from which the cabinet doors are made.

Installation of a hood in a wall cabinet

A hole is made in the bottom of the cabinet, the size of which corresponds to the size of the kitchen hood. The hood island is hidden in a cabinet. Fastening is carried out using holes in the lower edge, with the help of which the hood is screwed to the bottom of the cabinet.

In the shelf located in the middle of the cabinet, as well as in the ceiling, holes are made for the passage of a hose, one edge of which is attached to the hood, and the other is inserted into the hole in the central shelf and ceiling. In the mode when the air is discharged into the ventilation vent, the hose is passed into it, and in the filtration mode, on the contrary, it is cut off near the exit from the hole.

Rules for installing a hood with an air duct

This type of installation requires an air duct of a larger diameter and without bends. Air ducts should be made of thicker foil; thin foil will rustle when air moves. And PVC boxes are more flexible, their use is even more profitable. It is better if their shape is round and without bends. They have excellent sound insulation and do not resist air.

Under no circumstances should you narrow the passage for air or attach adapters that will hold it back. The required volume of air must pass in a certain period of time. If there are obstacles or narrow sections along the way, the hood motor will increase speed. Because of this, it wears out more and excess noise is created in the air duct.

When connecting the hood to the ventilation shaft, the filtration mode is used to overcome these obstacles. In order for dirty air to leave the kitchen space more effectively, there is an extreme way - to make a through hole in the wall above the surface of the hood.

Such a device can be beautifully decorated using polyvinyl chloride boxes. You can disguise a flexible air duct using such a plasterboard box.

Unfortunately, people do not always remember that fume hoods also need to be cleaned, so grease and dust accumulate on them. If the height when installing the hood does not reach 80 cm, the filter may catch fire from the open flame of the stove.

In any case, for safety reasons, the household hood must be provided with good grounding. Due to constant power surges in the network, its motor or electronic control unit may burn out. Another problem is that due to heating, spontaneous activation of the exhaust equipment may occur. Most people still decide to purchase a modern hood, which becomes one of the most important devices in the kitchen, ridding the space of unpleasant odors and fumes.
