Installation and connection of a kitchen hood. How to hang a hood in the kitchen - installation tips Installing a hood in the kitchen through the wall

For proper air circulation and creating a comfortable microclimate in the kitchen, it is necessary to install an exhaust system. It prevents the penetration of odors from the kitchen into other rooms in the apartment, especially if the kitchen is combined with another room. In addition, exhaust ventilation in the kitchen prevents fat from settling on furniture, dishes, and appliances surrounding the stove.

The need for a kitchen hood

The presence of exhaust ventilation in the kitchen is justified by serious reasons:

1. During cooking, a gas stove releases into the air a large amount of harmful substances that can harm the body: carbon monoxide, residues of unburned natural gas. In addition, there may be gas leaks from the equipment or pipeline.
2. When cooking on both electric and gas stoves, kitchen fumes are released when frying food, as well as water vapor. The latter is not capable of causing great harm to the body, but it violates the normal indoor microclimate. Kitchen fumes form harmful substances in the air that can settle not only on dishes, furniture and walls, but also inside the lungs of a person.

The presence of an efficiently functioning exhaust system in the kitchen is necessary not only for reasons of cleanliness and hygiene, but also for the safety of human health.

Owners of kitchen gas equipment should pay especially close attention to the presence of good traction.

Types of hood

Types of ventilation from the hood in the kitchen are divided into general and local. In the first case, air exchange is carried out throughout the room as a whole, including the cooking area, hob, dining area. This is a less productive option that requires additional air flow through the natural ventilation of the room. The second option is to install a kitchen hood directly above the hob.

Local exhaust, in turn, is divided into two types:

1. Filtering air, installation.
2. Pull-out umbrella.

The filter passes polluted air through itself, leaving all the soot and grease particles inside. The umbrella draws in the exhaust air and outputs it to the ventilation shaft. From the point of view of the efficiency of air purification, it is preferable to install ventilation in the kitchen of equipment of the second type.

Rules for installing exhaust ventilation

Before you install the hood in the kitchen with your own hands, you should choose it correctly:

1. It is necessary to determine the diameter of the fan. To do this, the exit of the ventilation shaft is measured, the value is rounded down - this will be the desired diameter.
2. To install a kitchen hood, you need to calculate the fan performance. To do this, you need to calculate the volume of the room, subtract from it the volume that the furniture occupies. The resulting value must be multiplied by 6, and by 12. It turns out two indicators of the lower and upper limits of fan performance. These indicators will help you choose the right fan model.
3. To prevent exhaust air from being drawn through the fan, it is necessary to choose equipment with a check valve.
4. No less important characteristics of the equipment for the hood are: the presence of a grid to prevent insects from entering; removable front panel for easy cleaning; having a timer.

Having chosen the necessary equipment, you can proceed to. In this case, it is recommended to follow some rules for installing the hood in the kitchen:

• The equipment must be properly grounded. Therefore, the installation of the hood in the kitchen is carried out by connecting to the electrical network with three wires: “phase”, “zero”, “ground” with wires in yellow insulation.
• To know how to make a hood correctly, you need to have an idea about connecting to the power supply. This is especially true for those wires of the device that are not equipped with a plug. In this case, the connection is made via a terminal block. For convenience, the socket for the terminal block can be made hidden inside the hood housing.
• It is necessary to mount the hood above the electric stove at a height of at least 70 cm, and above the gas hob, a distance of 80 cm must be observed.
• Before installing a kitchen hood, the building's air ducts should be checked for blockages. If the draft is bad, it is necessary to contact the housing office specialists to clean the mine.
• Before you make ventilation in the kitchen, it is important to choose the right duct. You can choose round aluminum corrugated tube or rigid plastic tube. In the first case, the advantage is lower cost and easy installation, in the second case, space saving during installation, more aesthetic appearance and vibration resistance.

Installing a hood in the kitchen

Do-it-yourself installation of a kitchen hood depends on the type and location of the ventilation duct. You can install ventilation inside the kitchen cabinet or make a separately located model in the form of a fireplace mantle or an inclined panel.

Installation scheme

Often violates the ventilation that is installed in the apartment. If you make another hole for the air outlet for mounting the hood, the quality of air exchange will not improve, since the cross section of the ventilation shaft will not change after such manipulations.

In order not to impair air exchange, an additional box with a special valve should be installed. The principle of its operation is simple: when the fan is not working, the valve is open, and natural ventilation occurs. When the fan is running, the resulting pressure closes the valve and thus forced ventilation takes place.

This installation scheme of the hood prevents the occurrence of reverse draft and the implementation of natural ventilation when the exhaust equipment is turned off.

In order to properly connect the hood in the kitchen, it is necessary to install the non-return valve correctly: in the horizontal channel, the damper mounting axis must take a horizontal position, and the heavier section should be tilted downwards. Without air pressure, the valve will be closed.

Fan installation

A homemade hood for the kitchen can be made from a fan mounted in the wall. For this you need:

1. Mark on the wall a place to install the fan, then make a hole of the desired diameter.
2. A fan is inserted into the hole, and the free space between the wall and the equipment is filled with mounting foam.
3. A grille is installed on the outside.
4. After the manipulations, the fan can be connected to the mains.

Do-it-yourself kitchen hood

You can make a hood in the kitchen with your own hands by embedding it in a cabinet or without it. Built-in ventilation looks organic with a kitchen set. The steps for its installation are as follows:

1. An aluminum or metal box with a check valve is made. For convenience, it can be purchased ready-made.
2. A hole is marked on the top board of the cabinet in accordance with the bottom cracker window. For the final installation, you need to outline the sides of the cracker.
3. A hole is cut in the bottom of the cabinet along the edge of the bottom of the hood.
4. Next, the shelves of the cabinet are removed and holes for the air duct are cut with a jigsaw to mount the hood.
5. A square hole is cut out on top of the cabinet board for the cracker window with an allowance of 3-5 mm along the edges.
6. A corrugation is installed: a corrugation is threaded into rounded holes, the upper end of which is formed by hands in the shape of a square and pushed into the upper hole.
7. The cabinet with corrugation is installed in place.
8. Do-it-yourself kitchen hood is inserted into the cutout hole in the cabinet. All joints of the corrugations, "crackers" with holes must be treated with silicone sealant, and then with mounting foam. Do-it-yourself kitchen hood is attached to the cabinet with self-tapping screws.
9. A corrugation is put on the exhaust pipe and secured with a clamp. It is not necessary to seal this connection, since this will make it difficult to disassemble for cleaning the ventilation, and will also create pressure drops in the area where the pipe passes into the corrugation.

When using not corrugated, but plastic pipes for air ducts, installation is carried out by connecting them to the component corners and further wiring to the ventilation duct.

If the installation of the hood in the kitchen with your own hands is carried out in the form of mounting a separate structure, a metal frame is made from a corner of 20–25 mm according to the size of the hob. It is attached to the wall under the socket of the hood. The air duct itself is installed under a drywall box. "Clapperboard" is placed on the upper cut of the box, just like on a cabinet.

To know how to make a hood in the kitchen yourself, you need to take into account the practical recommendations and advice of experts in this field. Summarizing these recommendations, the following can be noted:

1. Do-it-yourself ventilation in the kitchen should be not only exhaust, but also supply.
2. When installing the duct, it is necessary to avoid a large number of its bends in order to ensure good draft.
3. To ensure good traction, it is necessary to clear the shaft of the building from blockages.
4. Installing a check valve will help resist the supply of exhaust air.

The right one does not have a drive, a spring, but it has a damper, with an axis of rotation offset from the center.

It is well known that cooker hoods are used to remove exhaust gases and unwanted odors from cooking. The efficiency of air purification and the ability to maintain comfortable living conditions in the kitchen largely depend on the model of the exhaust device you have chosen. But before you hang the hood over the stove, you should thoroughly study the basic requirements for the technique of its installation. This issue is of particular importance in a situation where you have a gas stove installed in the kitchen, the operation of which is always associated with increased risks.

It is believed that the method of installing the exhaust device is quite simple and can be mastered by anyone. That is why in this article we would like to introduce you to the technique of installing kitchen hoods with your own hands.

Types of exhaust devices

All known types of exhaust devices can be divided into two large groups:

• circulating devices with built-in carbon filter;
• hoods built into the existing air exhaust system.

In models of exhaust equipment with a filter element, air is cleaned by forced circulation within the device.

In this case, polluted air first enters the system, and after cleaning in the built-in filter, it returns to the kitchen space again. Such models of exhaust devices are often installed in small kitchens.

In large kitchens, it is advisable to use hoods with a forced air intake mechanism, the outlet of which is connected to an existing ventilation system. With the help of such partings, polluted air is removed from the kitchen space to the outside (outside the premises). The efficiency of such exhaust devices is noticeably higher than that of partings with forced air circulation, so they are most often installed in kitchens with a large number of sources of pollution.

For successful installation of hoods with your own hands, you will need to follow the following rules:

• the distance from the stove to the intake casing (inlet plane) of the hood should not be less than 65 centimeters;
• the dimensions of the intake casing should approximately correspond to the dimensions of the gas stove;
• the electrical outlet used to connect the hood should not be located directly above the stove;
• when connecting the hood to the duct, its outlet pipe must have a minimum of bends.

Installation

Installation of a hood with a built-in charcoal filter does not require any special skills and special efforts from the performer. To install it, you will need a good level, with which, at the selected height, the control points for hanging the device are marked, and then holes for the fasteners are punched using a puncher.

The hood is fixed to the wall or wall cabinet using special hooks that securely hold it at the suspension points. When installing an exhaust device on the front of the kitchen set, it is best to use the niches that are always available in wall cabinets to place it.

The housing of the hoods with connection to the air outlet is fixed using the same fasteners (hooks), with the only difference that the place of their installation must be “tied” to the vent. After fixing the device in the selected place, an air duct channel is attached to its outlet (ordinary plastic pipes can be used as such a channel).

The main thing at the same time is that the pipes you use are sized to match the diameter of the air intake hole in the wall, which will allow you to avoid loss of pumping power. Upon completion of all installation procedures, a test check of the operation of the equipment should be carried out, which will allow you to verify that it has been installed correctly.

In the event that you need a separate outlet to connect the hood, all the wires that supply power to it can be “hidden” in a special cable channel. In addition, electrical wiring may be hidden under sheets of decorative material used to decorate your kitchen.

Note! It is necessary to provide a special protective device (the so-called “automatic device”) in the power supply line of the hood, which ensures that the equipment is turned off in case of an emergency.

We really hope that our article will help you figure out how to hang the hood over the stove so that you get rid of unpleasant odors in the kitchen forever and get the opportunity to enjoy fresh and clean air.

This is how the kitchen hood is installed:

During cooking, fumes and various fumes rise from the stove to the ceiling. After a while, it becomes difficult to breathe in the room - this means that polluted air is not drawn out well enough through the vent. Therefore, the installation of a kitchen hood for forced air circulation is required. But first you need to decide which mode of operation of the unit is required in your case, and then how to install the hood in the kitchen correctly.

Forced ventilation devices for the kitchen differ in their mode of operation. The units are:

1. the polluted air is pumped through a block of filters, consisting of preliminary (for coarse cleaning) and coal (for cleaning the air from odors). Such a unit does not require a connection to the ventilation duct, so in this case the installation will be the easiest. But, in terms of the quality of air purification in the room, this type of apparatus loses to flowing ones.
2. effectively pump out polluted air from the room into the ventilation shaft or duct, which is led outside (if you install the hood in a private house).

Connecting a neutral wire to a dead neutral

There are several types of air ducts for domestic ventilation on sale:

1. PVC (plastic) air ducts. They have good strength and light weight. Due to the smooth coating, they do not create noise when streams move along them.
2. Aluminum corrugated air duct - freely bends, stretches and easily adjusts to any size. It does not create vibration and hum, but it has an unaesthetic appearance, therefore, it usually hides in a closet, a special box or is hidden by a false ceiling.

Before you install the hood in the kitchen, make sure that you do not cover the only regular vent in the room with a pipe. In the case of one vent, they often break through another exit from the mine and put a check valve that will close the flow into it when the device is turned on.

There is also the option of using a special box with a clapper valve.

In the figure, the installed valve is shown in red. With the fans turned off, it lies horizontally, and the air can pass through the box naturally. When the fans are turned on, the valve rises and closes the air outlet back into the room, thereby directing it to the shaft. The material can be some lightweight material such as plastic or aluminum. But this option is not suitable if a built-in hood is being installed, since it is mounted in a wall cabinet.

For private houses, the best option would be to punch an additional hole in the wall for the channel and not affect the existing vertical one. In an additional hole you need to bring the air duct from the device. But the output must be set check valve to prevent outside air from entering.

check valve

If there is no additional channel in an ordinary apartment, and it is not possible to punch a hole in the outer wall, then this channel can be expanded and a special adapter, having two holes.

Through the lower grate, air from the room enters the shaft due to natural draft. At the same time, there is a visor in the upper opening, which prevents the air flow from the unit from escaping through the grille back into the room. Although there is, of course, back leakage, it is minimal compared to the outgoing flow.

The figure below clearly shows how the duct is connected to the adapter, while maintaining natural draft.

Thus, do-it-yourself installation of a kitchen hood can only be done by home craftsmen. Completing a task requires accuracy and care. Well, for those who do not have skills in handling tools, or do not have free time, the best option would be to invite a specialist to resolve this issue.

The question of how to mount the hood in the kitchen is of concern to many today. When making repairs in the kitchen, people in most cases think about how to create a more efficient ventilation system, because it is not only convenient, but even necessary.

A person who cooks regularly spends about five hours a day in the kitchen and breathes harmful fumes, including fumes and fumes.

In addition, during cooking, tiny particles and fats are released into the air from food, which also adversely affects human health.

The only way out in this situation is to buy and install a hood, since neither traditional ventilation systems nor simple ventilation will provide the desired effect. About how to properly put the hood in the kitchen and will be discussed in this article.

Hood selection

One of the most important systems in a person's home, providing the comfort of his life, is ventilation. In a sufficiently ventilated room, the air is clean and fresh, which is why it is simply pleasant to be here, while stuffiness can cause negative reactions of the body, up to general weakness and dizziness.

Cooker hoods are one of the main ventilation units, since cooking is associated with increased air temperature and harmful emissions, including very unpleasant odors.

The main task of the hood is to purify the air in the room. And the cleaning process itself can occur in different ways. The fastening of the hood for the kitchen directly depends on this. So, there are two types of work of modern hoods.

Types of hoods

1. The simplest exhaust 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 returns back. Sometimes such hoods are also called filtering or hanging hoods (see also the article about a hanging hood for the kitchen).

Advice! If the ventilation shaft is clean and “draws” well, then the valve can be removed from the hood and allowed to work with the engine turned off. This is possible in houses with controlled ventilation.

Connecting the hood to the ventilation

Since it is not difficult to fix the hood in the kitchen, you can cope with this procedure yourself. But it is better to take an assistant.

1. We attach the hood to the wall and mark its future position with a pencil. If you plan to change kitchen furniture, then you should consider integrating the hood into a hanging cabinet.
2. We drill with a perforator the walls under the dowel. You should not skimp here, since the structure must be fixed “tightly”.

Even cooking in a small volume is accompanied by unpleasant additions in the form of annoying odors, soot and fat. Eliminating these problems is simple: modern exhaust devices quickly and efficiently purify the air.

A modern kitchen hood will catch all unpleasant odors

To install the exhaust device, resort to the help of professionals. It's fast, reliable and simple. But he also has every right to life. In addition, it will not take much time by hand and save money. The owner will not need to worry about the quality of the work done, as he will try to do everything perfectly for himself. Do-it-yourself installation is another opportunity to deepen your knowledge in this industry.

Hood types

The type of exhaust device is selected depending on the technical conditions and the availability of access to the ventilation shaft. The most popular are filtering, exhaust and combined models.

Filtration devices operate on the principle of recirculation. The exhaust air mass is drawn into the structure, passes through the filter system and returns to the room already cleaned of odors and grease. Installing them is a breeze as these devices do not require a vent hole.

Exhaust models are flow type devices. Metal waste air mass and throws it out into the street through the ventilation duct. Their installation is more difficult, since it is necessary to bring the air duct to the street.

Depending on the design features, exhaust devices are divided into 4 types:

Each type has its own type of installation. It is easiest to install wall-mounted devices, the heavier ones are ceiling-mounted.

Correct location

The dimensions of the hoods are calculated depending on the dimensions of the stove or hob. It must be remembered that it should be 10-15 cm wider than the hob. If the device has a smaller width, this negatively affects the quality of ventilation. Grease and dirt constantly accumulate on the kitchen set, and the smell of food is felt in the air.

Self-installation of the hood does not require special professional skills

The mounting height of the device varies between 65-80 cm from the plate. The absorption of fatty impurities and steam directly depends on this value. A height less than the specified value is not used, since there is a possibility of ignition of fats that have settled on the filters for a long time. Yes, and working on a stove with a low-hanging hood is inconvenient. The device is not recommended to be installed above 80 cm, since in this case the lion's share of combustion by-products will pass by.

The device is installed near a grounded outlet. Therefore, already in worry about the location of electrical wiring and outlets. The cord should not hang over the stove and burners, otherwise it will either overheat or burn out. The wire is hidden in a special cable channel, which is attached to the wall.

In order for the device to work with maximum efficiency, good ventilation is provided in the house. To do this, install forced ventilation devices or use the ventilation function on metal-plastic windows. In extreme cases, open the window (but not in the cold season).

Mounting

Installing a household hood in the kitchen in an apartment is not particularly difficult. The device is attached directly to the wall or mounted as part of a kitchen set. When purchasing a wall-mounted hood for the kitchen, you need to consult the seller about the mounts that would withstand the weight of the device. The sequence of actions when installing a wall-mounted kitchen hood:

Assembly of the device requires great care and caution.

1. Accurately measure the distance between the bottom edge of the device and the mounting holes. Apply the markup to the wall and check with a level.
2. If there is already a stove in the kitchen, cover it with a film or paper to protect it from dust and dirt.
3. Drill holes for dowels.
4. Drive in the dowels, tighten the screws, adjusting their length.
5. Secure the air duct with a clamp.
6. Bring the ventilation pipe to the mine or to the street.
7. Cover the air duct with a casing (if any).
8. If there is, install it.
9. Connect the device to power.
10. Switch on and check the operation of the device.

Mounting the built-in hood in the cabinet is slightly different:

1. On the back or side wall, mark the holes for the exit of the exhaust pipe and cable.
2. Cut out the outlet for the air duct and drill a hole for the electrical wire.
3. Fix the air duct.
4. Bring out the pipe and cable.
5. Fasten the cabinet.

It is important to correctly connect the exhaust device to the mains. Electrical safety measures are mandatory. If you accidentally make a mistake, you can get an electric shock.

If the air duct needs to be shortened, it is not recommended to cut off the part that is inserted into the ventilation duct. The best solution is to cut the intermediate sections. In the place where the pipe enters the ventilation network, it fills all the cracks with mounting foam and carefully plasters. This improves the quality of ventilation and reduces side air leaks.

If the air duct goes straight to the street, then a check valve is installed on the outside of the vent. It does not allow air from the street to enter the kitchen.

Exhaust pipe installation

The kitchen hood is connected to the ventilation duct using corrugated or plastic pipes. The requirements for the duct are quite important:

1. The optimal length in the kitchen is no more than 3 m. If the duct is longer, with each meter the efficiency of the device decreases by 10%.
2. The minimum number of swivel elbows, adapters and bends. The more knees, the worse the ventilation. The resistance of the system increases sharply, and the exhaust air hardly comes out.
3. Bends and turns - exclusively at an obtuse angle. An angle of 90 degrees reduces efficiency by 10%. The air duct should smoothly move from one wall to another.
4. Smooth inner surface. In this case, ventilation will be efficient, as air resistance will decrease. The best way - . The corrugated air duct is ribbed, which creates additional obstacles for the outgoing air.

Exhaust pipe installation process - carefully read the instructions

Almost all models of devices are connected to a round air duct made of corrugated or plastic. Rectangular pipes look better, as they fit more harmoniously into the space between the cabinet and the ceiling. The diameter may be different, but the cross-sectional area must be at least 0.1 m 2. All connections are hermetically sealed to prevent the possible ingress of exhaust air back into the kitchen.

Plastic air ducts are strong, light and do not create additional noise during operation. Corrugated products also have many advantages: they are flexible, light, do not vibrate and do not make noise. But in terms of aesthetics, they are inferior to plastic counterparts.

The air duct is hidden in the free interior space of walls, furniture or ceiling. Two-level ceilings are convenient in this case: the pipe can be easily hidden above the lower level. If such options are not suitable, decorative boxes are used that match the style and color scheme to the kitchen set or walls. With your own hands, you can make a drywall box in the kitchen for the hood. On sale there are also boxes for the hood in the kitchen made of stainless steel.
