I want freshness, clean air. And not only on the street, but also in your home. Especially a lot of foreign odors arise in the kitchen during cooking. Installing a hood in the kitchen will help ensure comfortable conditions and a favorable microclimate. Modern manufacturers offer various devices for air purification in domestic premises. They differ in power, cleaning and installation methods, design and budget. How to make a hood in the kitchen, when the choice is made, the equipment is purchased and the only question that arises is its installation.

Let's look at how to install a hood in the kitchen with your own hands. The list of activities that need to be carried out for installation depends on several factors:

• type of exhaust device;
• indoor ventilation systems;
• power supply systems;
• type of selected duct.

General principles of work

Making a hood in the kitchen is not difficult, but there are certain safety requirements that must be met. This concerns the strength of the fastening, ensuring normal air exchange in the apartment, and protection against electric shock.

Design electrical wiring in advance.

An electrical connection is provided in the kitchen. The system must be grounded. In new houses, an appropriate circuit is provided and Euro sockets are installed. If connecting the house to the electrical supply requires grounding, then you should invite a professional electrician with permission to perform such work. It is better to install the socket close to the connection point, protect it from moisture, and prevent the wire from hanging over the stove.

Attention! Before mounting and installation, carefully read the manufacturer's instructions and turn on the device to ensure its functionality.

Installation of a hood in the kitchen begins with markings that will ensure that the hood is positioned along an axis running through the center of the stove or hob. Installation rules require that the mounting height when using gas stoves be 80 cm, and electric stoves 70 cm.

Choose the right distance to the stove

Installing a hood in the kitchen with your own hands will require you to be skilled and have a minimum number of tools:

• drill or hammer drill;
• level;
• screwdriver, screwdriver;
• knife and file for metal;
• tape measure, ruler;
• pencil.

A set of necessary tools

In the kit for the hood you need to purchase corrugation fastenings, a grille to design the place of connection to the ventilation shaft, a corrugation and a box.

Features of installation of various systems

Depending on the principle of air purification, kitchen hoods are divided into:

Depending on the type of fastening, hoods are divided into several types:

Let's look at how to properly install a hood in the kitchen with the installation of an air duct.

For domestic purposes, two types are used:
1. Plastic;
2. Metal (aluminum) corrugation.

Plastic air ducts have a smooth surface and do not create air resistance. They are more expensive than corrugations and more difficult to assemble, but they look aesthetically pleasing and do not require an additional box.

Installation of a plastic air duct

Important! To increase the power of the exhaust equipment, treat the connection points with silicone sealant.

Installation of metal air duct

An exposed corrugated pipe does not always fit into the interior, so you should plan in advance how to hide it. You can sew it into a plasterboard structure on the ceiling or arrange it in a box. It should be remembered that contaminants will accumulate in the pipe, and it will have to be changed periodically.

A DIY kitchen hood will provide access to secluded corners and make cleaning easier.

The installation of the air duct should be carried out by determining the most direct path to the ventilation shaft, without allowing the pipe to break. In this order, work is carried out when installing a wall-mounted, built-in or telescopic inclined hood:

1. Select a pipe with a diameter that matches the size of the outlet.
2. Stretch the pipe as much as possible to reduce noise.
3. Cut off the corrugation with a small margin for fastening.
4. Cut the edges and fold them outward.
5. Secure it to the pipe using a clamp.
6. Pull the pipe through the cut holes.
7. Fastening the hood corrugation to the ventilation shaft using a special grille, which is attached to the hole in the shaft.

Installing a hood in the kitchen should not affect the quality of air exchange in the room.

The ventilation duct must not be completely blocked. For this purpose, the grilles have not only a hole for the air duct, but also a special anti-return valve installed to ensure air circulation.

A homemade kitchen hood also has the right to life. If the size of the hole does not allow installing a finished grille, you can install an additional box made with two holes and a clapper valve. The firecracker is made of a lightweight aluminum or tin plate and is held in place by a thin spring. When the hood is running and air passes under pressure, the valve rises and allows it to escape. When the hood is turned off, the damper lowers and a hole opens for natural ventilation.

Check valve for air duct

A built-in check valve is used when air is discharged to the street. A hole is drilled in the outer wall and a grille with a check valve is installed. It will block access to cold air from the street when the hood is not working. The air duct connection is carried out according to the general rules.

Finally

When choosing and installing a hood in the kitchen, use the advice of experts. Competent work will help make your home comfortable and favorable for living.

Nowadays it is almost difficult to find a kitchen that does not have a hood. It plays a major role in this room, namely, it removes odors from cooked dishes beyond its boundaries, eliminates soot and heat, and keeps the furniture in its original form for many years. The majority of craftsmen who want to install such a mechanism at home are interested in the question: how to install it correctly and how to vent the hood into the ventilation? You can find out more about this below. But first, it is worth remembering that before carrying out the main work, you should choose the most suitable version of this device.

Without an exhaust hood, food odors from the kitchen will spread throughout the apartment.

Types of hoods

Modern hoods have differences in design. There are options for desktop, wall-mounted, built-in and island devices. Wall mechanisms come in rectangular and round configurations, covering the plane of the entire slab. It's hard not to notice her when you get into the room. Designs of this type should be combined with the overall appearance of the entire room. Built-in options are mounted in cabinets, they are practically invisible, which gives grounds for choosing a model of any plan.

A tabletop hood does not require installation; you can simply place it near the stove and plug it into the network.

Tabletop hoods are located near the stove or cooking surface. They are ideal for rooms with small areas. Island mechanisms are placed in the ceiling area, in the middle of the kitchen. They are perfect for slabs that stand separately from the set.

The nature of the installation work is directly dependent on the type of product purchased. That's why it's so important to choose the right option. Modern hoods come in three types: combined type, exhaust type and recirculation type.

The classic version of such a device is represented by a product that discharges air masses into the ventilation hole. Here we can talk about the exhaustive nature of her work. As air passes through the filters designated in the system, it is filtered and returned back. This is a type of recycling plan. The first option is represented by a conventional hood, the second by an air purifier. There is not much difference between them. Moreover, the bulk of modern systems are represented by combined varieties of such devices. They can operate in any of the above modes. When choosing the appropriate option, you should proceed from the characteristics of the kitchen and the current situation.

Surface preparation

The distance from the stove to the hood should not be less than 65 cm.

Before you put the hood in place, you need to decide on its location. Here you should check the quality of the walls. For installation of this system, preference is given to a strong and durable wall made of good material. The ideal option would be concrete or brick. It is also worth taking care of the appropriate fasteners; they must fit the chosen base. A properly installed hood should be located above the stove at a certain level.

Thus, the permissible height of the device above an electric stove is 65 cm, above a gas surface - 75 cm. The lower limits must be carefully observed, otherwise the device will fail and melt as a result of heating. The upper limits should be adjusted to the height of the owner. We should not forget about the width of the structure, which must be equal to the indicators of a gas stove, 50-60 cm. After choosing a suitable device, you can begin installation work. A hood installed in accordance with all the rules will delight you with safety and a long period of flawless operation.

The over-slab hood must be connected to the ventilation.

Devices of this type do not need to be connected to a ventilation shaft, because they are not capable of moving air masses outside the room. The effectiveness of their activities depends on the quality of the filters. Due to this circumstance, it is necessary to promptly replace the installed filters approximately 2 times a year.

Installing such an exhaust system is not difficult. To do this, hang it on the wall and connect it to electricity, first marking the mounting points and drilling holes with a drill.

Air duct installation: features

To keep the air in the kitchen clean, hood ventilation is necessary. It is very important to correctly install the air duct, which can be plastic, aluminum, or made on a semi-rigid base. The first type is much more reliable and costs much more than the other option.

Installing a plastic duct is much more difficult. For such purposes, you should acquire adapters, a ventilation grille, and horizontal and vertical elbows in the “L” configuration. You can’t do without special gearboxes that provide connection of round diameter to rectangular shapes. They perform the function of an air duct with an exhaust outlet.

The kit contains a fairly large number of elements that help carry out installation work of any level of complexity. It will not be easy for a novice master to carry out such actions, but such structures are designed for an indefinite period of use and make virtually no noise during operation.

Corrugation installation: nuances

If the ventilation is located directly above the stove, the process of connecting it to the hood is done through an adapter. In this case, an air duct is installed. Having chosen a smooth base of a square or round configuration, you should take care of acquiring a connecting elbow. It will help get rid of corners. You also need an adapter that is attached to the hood and to the ventilation hole itself. The connecting elements are treated with sealant - the result is a rather attractive and neat structure. It can be placed under the ceiling, without the need for additional decorating elements.

The desire to install an air duct in a closet allows you to use corrugation. This is an inexpensive material with which there are no installation difficulties. There is no need to use adapters; the corrugation itself bends perfectly, going around corner areas. Before installing it, it needs to be straightened. Manipulations of this kind can reduce the amount of noise produced during the operation of the mechanism. To correctly select the size of a corrugated pipe, it is important to take into account the diameter of the outlet hole located on the hood. The corrugation is installed using a clamp on the device, and on the ventilation - with a grille.

Advice. Over time, soot, soot and grease accumulate in the air duct, which must be cleaned regularly. This should be done approximately 2 times a year. You can resort to completely replacing it, because otherwise, air movement will be hampered and there will be a risk of fire.

Of course, it is not difficult to place the corrugation in the ventilation, but it will not look presentable and will not stand out with excellent performance indicators, like, for example, plastic samples. It is not very attractive from the point of view of external indicators.

The corrugation does not decorate the room at all, striking the eye as a bright spot.

The plastic system has a more noble appearance; its design features allow it to be installed on top of cabinets so that it remains almost invisible. A corrugated duct almost always makes sounds during operation. To reduce such unpleasant moments, preference should be given to materials of short length. As a result, sound vibrations will be minimized and the operation of the hood will improve. Sharp bends in the pipe should be avoided here.

A hood installed in the kitchen will provide maximum performance if the connecting channel for air exhaust is quite large. As a result, the masses will quickly go into the hole, and the effectiveness of such a device will be very high.

You should not resort to deliberately reducing the diameter of the air duct. If such a need arises, you should use an adapter, reducing the dimensions to a minimum. Ventilation located near the hood, on the same side, is very convenient. This option involves installing the system in the upper part of the kitchen cabinets. The location of such a channel on the other side provides the basis for laying the air duct along the ceiling. It can be disguised with special boxes in which it is easily installed. Matched to the color of the ceiling and walls, it will be almost invisible.

Ventilation through the attic or other rooms helps pre-cool the air. Condensation may occur in some areas. Over time, the traction force will decrease and mold will appear. Therefore, such a system should be finished with thermal insulation materials.

Many people, when purchasing a new hood, are not sure whether they can install it themselves, preferring to turn to specialists. This work does not cause any difficulties; it is enough to have basic skills in handling a drill and understand electricity. Another important point is the correct choice of model in accordance with the room. The productivity of the equipment should be 10 times the volume of the kitchen. The design of the product may be different, but the installation principle is almost the same. Let's look at the step-by-step process of installing a hood over a stove and the main features that may arise during operation.

The hood is selected based on the area of ​​the kitchen and the overall design

Features of installing kitchen hoods

Manufacturers produce different hoods, which differ in the method of attachment:

• built-in – installed in a cabinet in the form of a slider;
• flat - this is an independent device; it does not need access to the ventilation shaft. Polluted air is forced through a filter system and released back into the room;
• corner - this model is chosen if the hob is placed in a corner. The exhaust system can be supply through an air duct or recirculation;
• domed, inclined, fireplace - occupy the entire space above the stove, attached to the wall surface;
• island - installed on the ceiling above the hob, they take up quite a lot of space.

When choosing, it is important to follow the standards for placement above a gas stove or hob.

The corner hood fits very organically into the kitchen design

How to safely install a hood in the kitchen

A hood is an electrical appliance, so it is important to take care of safety during its operation.

1. In any model, fat and moisture accumulate and a breakdown may occur, as a result of which current will pass through the body. In this case, there is a high risk of electric shock. Therefore, first of all, it is necessary to ground the device. Modern apartments are equipped with a grounding loop; you don’t need to do anything additional, just turn on the hood.

If there is no grounding, you must draw the circuit yourself. A 3-core wire with a cross-section of 2.5 mm² is suitable for this. It does not need to be carried outside or attached to radiators; it is enough to simply extend it to the electrical panel, where it is connected to a dead neutral. If wiring is already connected to it, you just need to secure your wire on top.

1. When installing the hood, one more rule should be followed - the distance from the hob to the bottom border of the device must be within the limits specified by the manufacturer in the product data sheet.
2. Another important safety parameter is that the throughput of the ventilation shaft should be higher than that of the exhaust device. Otherwise, contaminated air masses will return to the kitchen or to neighbors through other openings in the ventilation duct.
3. The installation of the hood must be reliable, the fastening is strong enough so that it does not fall onto a hot stove during cooking. You need to be especially careful if the installation is carried out on drywall. In this case, it is necessary to additionally strengthen the place using wooden blocks.

Installing a Grounded Outlet for Safety

Tools and materials needed for work

Before starting work, you need to prepare the following tools and materials:

• air duct, additional elements if necessary;
• hammer drill. A drill with an impact function is also suitable, this will make the work a little more difficult if the walls are concrete;
• screwdriver;
• measuring tape or tape measure;
• level;
• hammer;
• fasteners;
• if necessary, a sheet of drywall, metal guides;
• primer, paint, brush, putty and tool for its application.

If an expensive tool is not available, it is not practical to purchase it for installing one hood. Many stores offer equipment rental for a short time. Installation will take no more than 2-3 hours, rental will not be expensive.

How to properly install an inclined or dome hood over a gas stove: main steps

The installation of inclined and dome hoods is practically the same; it should not cause any difficulties and it is quite possible to do it yourself, saving a certain amount of the family budget. Let's look at the entire installation process step by step.

Installation of a recirculating hood

This treatment system does not require connection to a ventilation shaft, so it simply needs to be mounted on the wall. This is a good solution for private houses or apartments in which the stove is installed far from the ventilation system.

The recirculating hood can be installed under the upper furniture if the height allows

Check valve installation

First of all, install a firecracker in the ventilation system or a check valve. It is necessary to prevent the return of air into the room. It is not difficult to make it yourself; to do this, you can take a piece of tin and make a box, the diameter of which should be 3/4 of the cross-section of the air duct.

Next, you need to take a small sheet of aluminum 5 mm thick, cut out the damper and attach it to the box with a spring so that air flows push it out when leaving the room. When air flows back, the damper must be closed.

The spring can be made from wire 120 mm long, 5 mm wide and 0.3 mm thick. Its tension should close the forcedly open damper and return it to its original position.

Operating principle of a check valve

Hood installation

After installing the clapper, you should secure the hood to the wall. Manufacturers provide the availability of fasteners along with the equipment. It is necessary to carefully measure the distance, the placement standards are indicated in the product passport, check the horizontal position using a level and drill a hole with a drill or hammer drill. Then drive in the dowel and screw in the screws.

Mounting the hood to the wall using self-tapping screws

Duct installation

The easiest way is to install a corrugated pipe. It can be stretched to the required parameters or cut with scissors. During operation, the hood does not produce additional noise and has excellent aerodynamics. The air duct must be connected with one side to the branch pipe, the other must enter the ventilation shaft.

A check valve must first be installed in the channel, the body of which must be attached to the wall. You can secure the duct connections using clamps. After which the entire structure must be covered with a plasterboard partition or a plastic box.

If the ventilation shaft is located at a distance from the hood, you can extend the air duct over a long distance. It must be remembered that with each turn of the corrugation, 10% of the pipe’s capacity is lost. In addition, it does not look very aesthetically pleasing. Therefore, in this case, it is worth thinking about moving the hob closer to the ventilation hole.

When installing the duct, there must be a gap between the ceiling and the pipe. This must be done due to the fact that during operation of the hood there is a slight vibration of all elements, which can damage the ceiling.

Installation and connection of a plastic air duct

How to independently connect a kitchen hood to electricity

Before installing the hood, you should first check the length of the cord and the distance to the outlet. In this case, it is not advisable to use a carrier; it is better to immediately move the outlet, but you should not place it close to heating equipment or water. The best place is to lay hidden wiring above the cabinets.

You can move the outlet yourself or invite a specialist. Then the place needs to be plastered and decorated after the repair.

Features of installing a built-in hood

A built-in hood in its technical parameters does not differ from an inclined or dome model. The main difference is in the design, for example, the casing in a tall product performs a decorative function. When installed correctly, the hood is almost invisible in the kitchen; only the control panel remains visible. It is suitable for small rooms or kitchens decorated in country, classic or rustic style.

To install such a structure in a house, certain professional skills are required. To place it, you need a cabinet, which is installed at the required distance above the stove. You can use existing furniture for exhaust equipment or make a cabinet individually.

Let's look at the step-by-step process of installing a hood in already installed furniture.

1. The bottom and shelves of the cabinet should be removed. You can install additional fasteners for rigidity.
2. You need to cut a hole in the top panel for subsequent installation of the air duct. It can be cut out with a jigsaw.
3. Install the hood in the cabinet and secure it with self-tapping screws.
4. Next, you should hang the cabinet with the hood in place.
5. Install and secure the air duct.
6. Connect and check the operation of the system.

A corrugated air duct in sight can ruin the design of any kitchen. It is recommended to hide it inside furniture or use a decorative model. An alternative is to install a plastic structure, which visually looks much better.

The sequence of installing the hood in the cabinet

Hood installation height

Manufacturers indicate the dimensions in the technical notes for the product, since they directly depend on the power of the equipment. The optimal height for installing the hood above the hob or stove should be in the range from 65 to 95 cm from the bottom edge of the model to the burners:

• for gas - from 75 cm to 90 cm;
• for electric – from 65 cm to 70 cm.

If you install the hood lower, individual elements may be damaged due to high temperature, steam and splashes.

It is possible to install a hood at a height of more than 90 cm only if the power of the equipment allows it.

How to choose an air duct for a kitchen hood

Air purification in the kitchen depends not only on the power and performance of the equipment, but also on the correctly selected air duct. The trading network offers the following elements:

• corrugated pipe made of round aluminum foil, the main advantage of which is low cost. The air duct bends well, so installation does not cause any difficulties. Additional elements for organizing air purification are not needed; you may only need clamps with which to secure the corrugation to the hood and ventilation grille.

Disadvantages include uninteresting appearance and vibration when the device operates at high power;

• rigid plastic pipes - to install the ventilation duct, it is necessary to purchase transition parts: turns, connections. The elements are produced in round and rectangular sections. The finished structure has a presentable appearance and good sound insulation. The main advantage of rigid pipes is their small height, so they can be hidden even in a suspended ceiling.

When choosing an air channel, you should focus on the diameter of the outlet - the bell; in addition, it is important to correctly measure the distance to the ventilation shaft. For a corrugated pipe, the difference due to incorrect measurements will not affect the installation; for a rigid air duct, this can lead to the purchase of unnecessary parts.

A variety of elements of the plastic air duct allows you to perform complex piping

Conclusion

Installing a hood over a gas or electric stove will take 1-2 hours; the work is not difficult. Therefore, before turning to professionals, you should try to install it yourself. It is important to follow safety precautions and take into account all the features that we have described. And then its operation will reliably protect the room from unpleasant odors.

A slider hood installed in a cabinet does not clutter up the kitchen space

The method of installing this device will depend on its operating mode, of which there are 2 in total:

Retraction mode

Recirculation mode

The installation of a hood, which operates in exhaust mode, includes the outlet of the air duct into the ventilation system. To do this, it is very important to choose the right diameter of the air duct - it should not exceed the permissible parameters of 120-150 mm.

Advice! When installing the air duct, it does not need to be bent or extended, as all this significantly increases the loss of power: each turn reduces power by as much as 10%.

When choosing an air duct, you need to give preference to those that have a smooth surface, because corrugated hard pipes “sound” too loudly during operation of the equipment.

Installing a hood with a carbon filter does not require venting, because all the air that enters it is cleaned and returned to the room. Installation of such a hood is quite simple, but the filters will have to be changed periodically.

No less important is how exactly the hood will be attached, it depends on its type.

Types of hoods

Hoods are:

Hanging - fixed above the stove under the cabinet

Built-in - fixed in a special cabinet without a bottom

Wall-mounted - mounted on the wall

Corner - fixed in the corner of the room

Island - fixed directly to the ceiling anywhere in the room

What tools will you need?

To install a kitchen hood you will need the following tools and materials:

Corrugation and a pair of clamps for fastening it

Grille for ventilation duct

Hammer

Screwdriver

Hacksaw for cutting metal

Building level

Screwdriver

Roulette (for marking).

Installation of the hood usually begins with the most difficult thing - connecting the hood to the ventilation shaft. And it would be best not to punch another hole, enlarging the window of the ventilation shaft, but to install an additional box with a special valve that will prevent air from returning back into the room.

Here is its schematic view:

How does it all work? If the valve is closed (the valve is the red line), the air simply exits through the ventilation hole, and if the hood starts and the fan starts working, then it changes its position and closes one of the windows, and ventilation in this case is carried out using the hood itself.

The main task of this entire system is to prevent the occurrence of reverse draft and the possibility of natural ventilation if the hood is turned off.

To construct the mechanism, you will need a spring and an aluminum or plastic sheet to construct the valve.

Of all the possible types of air ducts, it is better to choose those made of plastic or aluminum.

Plastic pipes are very light and do not create noise when the hood is operating; moreover, there is no need to hide them, they fit perfectly into the design of the room and do not disfigure it.

Aluminum corrugated pipes also do not make noise during operation, but they do not have a very attractive appearance, so many people puzzle over how to hide the corrugation from the hood. One of the best ways is to install it in a plasterboard ceiling.

Before you begin installation

Before installation, you need to find out all the points regarding connecting the hood to electricity. At the same time, it is extremely important to comply with all electrical safety standards, because during operation the hood will constantly be exposed to drops of fat, moisture, and so on, which is why its housing requires mandatory grounding to remove voltage.

To connect the hood you need 3 wires: phase, neutral and ground. It is necessary to provide the equipment with grounding. This can be done using a ground loop (if available) by simply connecting the wire to the appropriate terminal.

But what to do if there is no grounding in the apartment? In this case, you will have to connect the wire to a dead neutral. To do this, you need to open the electrical panel with the meters and find there a pipe with all the wires or a special bus, as in the picture:

On it you need to find a pin on which the neutral wires are already located. You will need to throw your wire over them and tighten the washer. After this, the wire is routed to the kitchen, and the hood itself is connected through an automatic separator.

Before you begin installing the equipment, you need to start making a firecracker box. It is manufactured in accordance with the diagram (figure above), or you can take a simpler route and purchase an anti-return valve. The entire structure will be installed in front of the ventilation hole in the wall.

After this, you can prepare the cabinet. To do this, you need to mark its lower wall and, in accordance with the marks, drill a hole there for the hood. If the cabinet has shelves, then you will also need to drill round or square holes in them for the air duct.

The upper wall of the cabinet should be drilled in the shape of a square and with some margin (3-5 mm) for a clapper box.

When the cabinet is ready, you can begin connecting the air duct. To do this, you need to pull it through all the drilled holes, cut the pipe and bend its edges outward. After this, the cabinet can be hung on the wall.

Important! All joints of the air duct must be treated with sealant so that the hood does not subsequently lose its power.

The air duct stretched in the cabinet is connected to the ventilation duct through an anti-return duct. The firecracker is attached to the cabinet using silicone.

After the main elements are connected, you can fix the hood body itself in the cabinet. It is screwed onto screws or dowels. The corrugation is attached to it using a clamp.

If you need to secure not a corrugation, but a plastic air duct, then you just need to connect all the components correctly:

Installation height of the hood above the stove

A very important factor that needs to be taken into account before installing the hood is its height above the hob surface. This parameter will depend on the type of tile itself:

If you need to install air purification equipment above an electric stove, then the distance between them should not be less than 70 cm.

For a gas stove this parameter is 80 cm.

Compliance with these parameters allows you to ensure effective air purification in the kitchen. If the height between the stove and the hood is less than 70-80 cm, then the heated air emanating from the hob can affect the performance of the device and damage its important elements.

If the device is mounted not in a cabinet, but directly on the wall, you can use the built-in fasteners or build a U-shaped frame from the corners. This frame will serve as a reliable support for the hood body.

In some cases, ordinary dowels are not suitable for fastening; this is a fairly common problem for those whose gas stove pipes interfere with normal fastening. To solve the problem you need to use long self-tapping screws. At one end they have a thread with a nut to which the device body can be screwed.

How to connect the hood to the mains

The final stage is connecting the hood to the electrical network. This is done in two ways:

Through a socket

Through a safety circuit breaker

It is very important to remember about grounding, which was already mentioned in the article above. Thanks to it, you can remove the voltage from the housing and the hood fan.

Once everything is ready, you can decorate the hood with a decorative hood and protective air ducts and feel free to enjoy all the benefits of this equipment.

Installing a kitchen hood is a fairly simple procedure, especially if all electrical safety rules are followed and the necessary tools and materials are available. And the only thing that will then be required is to clean the equipment from grease and soot 2 times a year to prevent fire.

Installing a hood over a gas stove - video

A video that will help you understand in more detail how to install the hood and select the necessary elements for installation:

Nowadays, it is difficult to even mentally imagine a modern kitchen without a kitchen hood, which serves to effectively remove combustion products, kitchen aromas and fumes. Today's modern market is replete with a great variety of hood models, which differ in the installation method. Today we will talk about how to correctly and competently install this electrical device.

First, you need to decide on the height at which the hood will be located. Since, if you install it at an excessively high height, the electrical appliance will not work effectively. This means that all vapors and odors will remain in the room. If the hood is mounted too low, it will interfere with work at the stove, and may pose a risk of ignition of grease that has accumulated on the filters over time. The most reasonable thing would be to install the device at a distance 75 cm from the gas hob to the bottom panel of the hood. From an electric hob, 65 cm will be enough.

Connecting the hood to the duct.

Also, before installing the hood, it is necessary to consider how exactly the air will be discharged through the ventilation duct. In most cases, the architecture of the room and the placement of kitchen furniture in it do not make it possible to install a hood near the ventilation hole. In addition, air ducts with a large number of bends (elbows) increase the noise level and significantly reduce the performance of the electrical appliance. It is also necessary to ensure that after installing the air duct, the ventilation duct is not completely blocked.

To do this, special grilles are installed on which there is a place for attaching the air duct, as well as a special valve. When the hood is operating, the valve closes, and when it is not working, the valve opens to ensure natural air circulation.

If the dimensions of the ventilation duct do not allow the installation of such a grille, then you can use an air duct with an installed check valve.

Types of air ducts.

Air ducts can be divided into corrugated and plastic. Corrugated air ducts are made from thin sheet aluminum. To install such ducts, a grille with fitting and a clamp are required.

During installation, the air duct is stretched to establish the required length. If unstretched folds of the air duct remain, the operation of the hood will be accompanied by an increased noise level. Corrugated air duct is relatively cheap and easy to install.

Plastic air ducts come in rectangular and round cross-sections. Air ducts with a rectangular cross-section are less noticeable, and they can also be laid along wall cabinets of kitchen furniture.

To install a hood with a plastic air duct, you must have L-shaped adapters and adapters specifically designed for the ventilation duct and the electrical appliance itself. Such air ducts are distinguished by the absence of noise during operation of the hood. Dirt also does not get into them due to the absence of holes and cracks.

The nuances of installing a hood.

You should know that the device will be installed technically correctly if the diameter of the air duct is larger than the outlet of the hood itself. If you do not adhere to this rule, the load on the unit’s engine increases, noise appears and the efficiency of the device decreases.

Before installing the hood, it is preferable to first install the furniture in the kitchen, or make precise markings of it. This will allow you to determine the location of the outlet, as well as the placement of the air duct. Since hoods come with fairly short cords, the socket should not be located too far away. It is also not allowed to squeeze the cord, place it close to the stove, or sag.

Layout of electrical outlets in the kitchen.

What types of kitchen hoods are there? Types of hoods.

The installation of a hood in the kitchen will depend on the type of hood chosen. The following types are distinguished:

• Dome hoods are the most powerful, they resemble an umbrella from which a pipe extends;
• Hanging (also called flat and standard) - mounted under the cabinet above the stove.
• Built-in – installed inside a wall cabinet or in a table, so they fit perfectly into any design.
• Wall-mounted - mounted on the wall above the stove; they can have a different body design.
• Corner – installed in a corner.
• Island hoods – designed for kitchens with an island. You can fix it anywhere in the room by hanging it from the ceiling.

Kitchen hoods may differ in design and technology.

In addition to the type of design, hoods differ in ventilation mode.

• Flow-through draw polluted air from the kitchen into the ventilation shaft. This method of ventilation is called air exhaust (exhaust mode). It is the most efficient and productive.
• Recirculating hoods– they pass air through carbon filters in the housing, obtaining fresh air at the outlet. It does not require ventilation in the kitchen in the apartment, so its installation can be called simpler, but less effective in terms of cleaning.

Calculation of kitchen hood power.

An important parameter when purchasing a hood is its cleaning performance, which is measured in cubic meters per hour. As you might have guessed, this value shows how many cubic meters of air the hood will pass through itself per hour of operation. According to the standards established in Russia, the air in the kitchen must be renewed 12 times per hour. Therefore, you can easily calculate how much power you will need using this simple formula:

Kitchen area * Ceiling height * 12 times

It is also worth taking into account the reserve for power loss due to bends of the air duct, the length of the ventilation shaft and other parameters; for this, add 30% to the result obtained.

For example, if your kitchen has an area of ​​6 square meters. m. and the ceiling height is 2.5 m. then the calculation will look like this:

6 * 2.5 * 12 * 1.3 = 234 m3.

Advice! Also, when purchasing, you should take into account the noise emitted when the ventilation is on, which manufacturers indicate in decibels. You should not buy models that produce noise above 50 dB. There are practically silent hoods with two fans or one external one. In addition, some models are equipped with sound-absorbing pads.
