The kitchen is important room in an apartment or house, so it should be equipped with everything to ensure a comfortable cooking process. First of all, it is worth considering the arrangement gas stove and hoods. The hood is of particular importance: it will eliminate all odors, as well as the settling of fat, fumes, and juices formed during cooking. Its normal functioning depends on the connection, for this reason it is important to know how to properly connect the hood to the ventilation in the kitchen. If you follow all the steps during this process, then in the future unpleasant odors will not apply to the entire premises.

Hood integrated into ventilation

Surface preparation

The hood helps eliminate unpleasant problems that usually arise during the cooking process: fat settling, evaporation, unpleasant persistent odors. She draws all the dirt into herself and removes it. But the full functioning of the device depends on its correct installation.

Before installing the hood, it is worth considering its location in advance. Of course, it should be installed above a gas stove, but you should also not forget to pay attention to the quality of the wall surface. For this reason, in order to choose the right area for installing this product, it is worth studying the important features:

• First of all, it is recommended to check the quality of the walls. To install this system, you should choose a strong and durable wall that is made of a high-quality base;
• most suitable option for installation of the hood there is a wall surface made of concrete or brick;
• It is imperative to prepare fasteners; they must fully fit the selected base;
• When installing a hood, it is worth considering that it must be located above the stove at the correct height.

For installation a wall will do made of concrete or brick

Particular importance is given to height, it depends on it correct functioning of this device. So, in order to correctly determine the required height level, you should follow the following recommendations:

• permissible height above the surface electric stove is 65 cm;
• the maximum height above the surface of the gas height should be 75 cm;
• It is imperative that the lower limits be strictly observed, otherwise the device may fail during heating and melt;
• the upper boundaries of the product must be adjusted to the growth of the owner;
• definitely need to know correct parameters width, they should be the same as that of a gas stove - 50-60 centimeters.

After the surface for installation has been selected and purchased suitable model hoods, you can begin installation. The structure, which will be installed and connected in accordance with all rules and recommendations, will be able to last for a long time.

Selection and installation of air ducts

It is imperative to select an air duct through which unpleasant odors will be removed from the kitchen area. Special requirements for this product is not available, for this reason there should not be any special problems with its choice.

Kinds

There are three types of air ducts:

• aluminum corrugated sleeve. The main advantage of this element is that it can be easily given the desired shape. It bends easily at any angle. In order to install it, a part of the sleeve of the required length is taken and given the desired shape. However, this type of air duct has several disadvantages - the operation of the hood is quite noisy, this is due to the fact that the flow of exhaust air causes strong resonance, but the presence of ribs on the surface of the sleeve can cause some difficulties when removing air. It is also difficult to care for; dust, grease, and soot often get clogged between the ribs, which are difficult to clean;
• plastic round (PVC). This type of air duct is assembled from several sections of plastic elements - curves, bends, adapters, couplings. The connection to the pipe is made thanks to the presence of extensions on the shaped elements. In order to prevent separation during installation of the air duct, this type of joint can be coated with glue or secured with self-tapping screws. The main advantage of these devices is that the air exchange process in them is silent. Also, the smooth surface of the walls does not create obstacles for the passage of air;
• square ducts made of plastic material. These devices are made of polyvinyl chloride (PVC), they have a cross-section with rectangular shape. The remaining qualities of this device are the same as those of others. Typically, rectangular air ducts are used in cases where it is necessary to save space in a room.

Installation Features

In order to clean the kitchen area from unpleasant odors and fumes that are formed during the cooking process, you need to connect the hood to the ventilation. And to do this you will need to do correct installation air duct.

Plastic air duct

To ensure that the installation of this element is correct and of high quality, you should pay attention to several important features:

• For exhaust, air ducts made of plastic material or aluminum, which is made on a semi-rigid base, are suitable;
• A plastic device is considered the most suitable, but it is quite expensive;
• Installing plastic air ducts has some difficulties. In order for it to be of high quality and correct, you need to purchase additional elements - adapters, ventilation grille, elbows with horizontal and vertical view, which has a configuration in the form of the letter “G”;
• You will definitely need a gearbox that acts as a connecting device for elements with a round diameter with products of rectangular shapes.

Plastic air ducts are equipped with many additional elements, which help to carry out installation work with any level of complexity. But it will be quite difficult for a novice master to complete this work, for this reason it is better to entrust this work to professionals.

The length of the air duct is at least 3 meters

Although plastic products are high cost and difficult to install, they have high qualities. They are designed for indefinite use, and they do not make noise during the working process.

Attaching the corrugation to the hood and ventilation

If you decide to save money or you do not have the opportunity to purchase a device for removing air from plastic, then corrugation would be a suitable option. But in order to properly connect it to the hood and ventilation, you will need to observe some important nuances.

Installing corrugations on the grille

To keep the hood functioning top level needs to be thought through correct fastening corrugated air duct to the body. For fastening you will definitely need clamps with suitable sizes. They can be made of a metal or plastic base.

In order to perform, you may need a special ventilation grille. There is a hole in the upper part of this element, which is intended for connecting an air duct pipe. At the bottom of the product there are holes that are needed to remove air from the kitchen area due to natural circulation during the period when the hood is not in working condition.

A grill with a protrusion is suitable for installing corrugations. Around the hole of this element there is a side with a size of 2-3 cm, a corrugation is put on it. After this, it is fixed using clamps with suitable sizes.

The corrugation is also connected to the hood. It has a special protrusion on which the corrugated air duct is installed. After this, you need to tighten it using clamps with the required dimensions.

How to install a dome hood

In the modern market of household appliances, hoods with dome shapes are especially popular. They fit harmoniously into the kitchen space and cope with their functions perfectly. These products, in turn, are divided into several subtypes:

• fireplace (wall-mounted). These devices are fastened to the wall surface. The design of products of this type is similar to ventilation systems for fireplaces;
• corner. Hoods with this configuration are rare in kitchens. They are installed only in cases where the stove is in a corner;
• island. These options are installed only in large rooms, for example, in dining rooms. They are suitable when the gas stove is installed in the center of the room. The devices are fastened to the ceiling surface.

Types of hoods

In order to install correctly, you need to know the main features of this process. It is advisable to trust this work professionals, they will be able to do everything correctly and efficiently.

Dome hood installation option

If you decide to spend self-installation hoods, be sure to remember a few important recommendations:

• To install, you need to connect the hood to ventilation system and connect the device to electrical network;
• It is advisable to furnish the kitchen area with furniture in advance, and only after that mark the location of the hood. In this case, it is necessary to take into account the height of this device;
• Next you need to drill holes for the dowels. We mount supports to them using bolts, onto which the base of the exhaust device is placed;
• after this, a special tap connection is made exhaust device with a corrugated air duct, while tightness must be observed;
• At the end, the operation of the hood is checked and the upper casing of the device is put on.

Connection requirements

The hood must be installed correctly, taking into account all important requirements. Required condition during installation this device- this is compliance with the grounding of the existing electrical outlet. If you don't know how to do it this process, then it is better to seek professional help.

Correct connection of a kitchen hood to ventilation

Almost every house or apartment has a ventilation system to which an exhaust hood can be connected. In the bathroom and toilet, special vents with grates are usually installed, which lead into a common shaft.

Ventilation connection device

Features of device installation depend on the choice of connection method. The exhaust device can go into the area of ​​the ventilation hole or immediately outside the room, for example, to the street. If the kitchen area has a separate air exhaust duct, this will greatly simplify the installation process.

Installing a separate channel can prevent many problems that often arise when using general ventilation. Often, exhausted air, fumes, grease, soot, which enter the general ventilation system, lead to the formation air lock, which can cause disruption of air exchange in all apartments.

Exhaust hood into a separate air exhaust duct

To prevent all unpleasant situations and problems, it is better to make a separate channel for air exhaust. When organizing it, it is worth considering the following actions:

• in external wall you need to drill holes using a diamond drill;
• after this, a safety grille with a check valve is installed;
• we carry out an exhaust hood to the check valve;
• check valve can be made of two moving flaps that are installed in the air duct;
• after the exhaust device is turned on, the doors open, and after it is turned off, they close. This will protect the room from cold air entering it.

Installing an exhaust hood and connecting it to ventilation is complex process. During it, you must comply with all established requirements and rules on which further proper functioning depends. of this device. In order to properly connect it to ventilation, you definitely need air ducts, which can be made of plastic or corrugated aluminum material. It is better to first study the characteristics and features of these products.

The kitchen is the main room in any apartment or country house, here the hostess spends quite a lot of time every day, and all family members are sure to come here at least twice a day. In this small but quite cozy room, the delicious aromas of homemade pies and cooked food are constantly in the air. To prevent various odors from spreading throughout the entire apartment, it is necessary to correct connection kitchen hood.

Before you go to a specialized store to make a purchase, you need to discuss with everyone at home hood type so that there are no disagreements later.

Before purchasing, make the necessary calculations on how much power you need for the hood depending on the size of the kitchen.

Manufacturers household appliances launched the production of different exhaust systems, which not only have differences in installation, but also function differently.

1. Wall option - big choice case design, it will be easy to match your headset. Installation is carried out above the slab on the adjacent wall.
2. Corner- are considered ideal solution for a small kitchen, where every centimeter is valuable, installation is carried out on the wall in the corner.
3. Hanging type- they are flat, suspended above the stove under wall cabinet, fit perfectly into the interior.
4. Built-in type- installed inside the headset.
5. Island - universal type hoods are used in large rooms where the stove and cutting table are in the middle of the kitchen.

You made a choice and purchased the option that you think is best. Now a natural question arises: how to connect the hood in the kitchen so that everything works correctly, fulfilling the required sanitary standards and security measures.

Connection requirements

First of all, check whether the apartment has grounding. If you live in a house with built-in electric stoves, then this issue disappears - grounding was carried out during construction. If you don’t have one, don’t be upset, there are many options for how to properly ground a modern city apartment, and what conditions are required for this. It will be easier for those who have own house. Read more about these methods in the article on grounding.

We must not forget about separate outlet for a hood that is installed at the level of the system hood or slightly higher: in this way it is connected to the electrical network of an apartment or private house.

You will have enough general knowledge of the operating principles of similar systems to adequately cope with the installation. You can find detailed videos on the Internet that will help you understand the nuances of this process.

Ventilation features

During the construction of any residential building, a ventilation system is provided. When you or a called technician connects the hood in the kitchen, it is disrupted in any case. To reduce damage to a minimum, it is recommended to install additional box with valve.

The principle of operation of such a valve is very simple: when the hood is turned off, it is closed with a lid, and the air comes out by gravity; when food is cooked and the hood is turned on, the valve closes the hole with the force of air pressure from the fan natural ventilation. The main advantage of such a system is reverse thrust missing completely.

At home old building are equipped with an outdated natural ventilation system, so before connecting a kitchen hood to home ventilation, you must invite a specialist for consultation. Only he can tell you what power the model needs.

Many users take it outside individually: drill outer wall and remove all odors into a personal window with a 100% guarantee.

Connection steps

Work must begin when all the furniture in the room is already in its specific place, especially when the hood connection diagram is built into the kitchen unit.
Regardless of the type, the hood is located above the surface of the stove at a height of at least 60 cm, and the final height will depend on the height of the housewife, so that it is convenient to cook and not hit your head on the sharp edges of the umbrella. This way you will comply with all basic safety requirements.

You can install a simple hood model yourself; you don’t need any special knowledge for this - you need to be able to use a standard set of tools, and have the desire to do everything conscientiously, with excellent quality.

We will consider a simple case mount exhaust system to the wall of the room:

1. We fix the U-shaped shape with dowels corner frame- this will be a support for the entire body.
2. If they interfere gas pipes, then we take special long screws in the form studs- on one side they look like an ordinary self-tapping screw, and on the other there is a thread for a nut. First, screw them in like self-tapping screws, and then install the exhaust system housing on the nuts - as a result, the hood will be at the required distance from the wall.

Self-tapping screw

1. We fix it on the neck of the umbrella corrugation using a special clamp.
2. We connect the structure to the home electrical network using special socket.
3. We check the operation of the entire system. If everything functions correctly, then we connect the corrugation to a special plastic grille, which decorates the entrance of the ventilation shaft. Pre-coat the joint area sealant to eliminate losses during system operation.

Attaching the corrugation to the grille

When installing hood outlets, adhere to simple rule- the fewer pipe bends, the better the traction. Each turn reduces efficiency by 10%.

System filters need to be washed periodically, and fan bearings lubricate. You will learn how often to do this from the operating instructions.

Separate line or outlet

If there is grounding in the house, then it is enough to install only an outlet to connect the hood to electricity. Here we must remember that it must be placed above the system umbrella so that dirt does not fall on the body.

When there is no grounding, it is necessary to carry out separate line from the transfer case. It’s good if it’s on the wall in the hallway - you just need to drill the wall, take out the wires and fix the socket in the right place.

If the transfer case is located far away, then serious work remains: trenching the wall, laying a wire, connecting to electrical panel. And this is a separate conversation.

How to properly install sockets for connecting all household appliances on modern kitchen, shown in the diagram.

Although many home craftsmen do not trust it, it copes with the task much better than plastic pipes round or square section. Installation is much cheaper, there is practically no loss of efficiency, which cannot be said about air duct pipes. During installation, it stretches as much as possible, which reduces the noise level.

It is necessary to clean corrugated pipes and plastic pipes 2 times a year so that they do not become heavily clogged with specific accumulations.

Do not hesitate to consult with a professional before installing an exhaust system. An excellent option if your friend has already encountered an installation problem - call him to help you, after all the work is completed you will not regret it.

During installation, every stage is important: you just need to make a slight mistake horizontal installation hood, and this will inevitably create problems in the future that are currently invisible. Damaged little sealant and there are gaps left that are invisible, but after some time this will affect the efficiency of the installation. The following mistakes are made quite often, even by professional builders:

1. A pipe is walled up in the ventilation shafts, and an exhaust system with a check valve is directly connected to it. When the hood does not work, there is no ventilation of the room, because the valve closes the pipe if the fan does not work.
2. When installing, a pipe with a diameter of only 100 mm is used, and this is not enough - you need to use a pipe with with a diameter of at least 125 mm. Then, within an hour, contaminated air with a volume of up to 350 m 3 /h will be removed from the kitchen.

You can eliminate such defects yourself by widening the entrance to the ventilation shaft and installing a special grille with a round entrance for the exhaust system.

After all the work is completed, the stuffiness in the room will disappear, the noise from the hood fan will decrease - in the updated kitchen you can comfortably drink a cup of tea with friends.

The exhaust system is positioned as a very important attribute for the kitchen, which is used to remove foreign odors, particles of fat and soot. These elements can appear during the cooking process and settle on the walls of the room. Self-connection connecting hoods to a centralized exhaust system may present certain difficulties. It should be understood that incorrect installation work may adversely affect the subsequent operation of the device. To avoid possible negative consequences it is necessary to approach the resolution of this issue very carefully.

Design and principle of operation of the exhaust system

IN constructively The exhaust system is quite simple. It consists of a motor that drives the fan, as well as several filters that can trap fumes, soot and foreign odors. The fan creates air draft and forces dirty air to pass through the filters, cleaning it from various elements. According to the principle of operation, the exhaust system can be flow-through or circulation.

Circulation type hood

This variation of the device is not very popular. And this is due not only to its high price indicators. Flow hood more practical and multifunctional. Some models of such a device are also capable of operating in circulation mode.

Circulating hoods, using the draft created by fans, absorb polluted air, purify it through filters and return the air masses to the room. In such systems, two filter elements are most often used. One of them is designed to clean soot and grease, and the second is for air purification. In order for them to function over a long period of time, it is necessary to regularly carry out a set of measures to clean the filter elements.

The filter used to clean fat and soot is in most cases made of non-woven fabric or padding polyester. IN Lately The metal variation of the element is becoming increasingly popular. This filter can be used for quite a long time, but periodically it is necessary to wash it in a solution prepared from dishwashing detergent. Instead of one large metal filter, several small ones can be used.

Flow type hood

In this case, the air that gets inside the exhaust system does not return to the room, but goes outside. Carrying out installation work in this case will be somewhat more difficult, since there is a need for additional installation chimney pipes. In addition, the issue regarding connecting the hood to the hood should be resolved.

Hood flow type able to combat pollution more effectively. Due to the creation of a difference temperature indicators Fresh and purified air enters the kitchen. Characteristic feature Such a system can also be called the fact that there is no carbon filter. Instead, a grease filter element is used.

In addition, an additional filter is installed here, which protects the parts of the exhaust system from the deposition of grease and dust particles. Models that do not contain these elements require more painstaking care.

Variations of exhaust systems

If we talk about the classification of hoods by installation method, then it should be noted that there are several variations of systems. Depending on the placement features, hoods can be represented by the following variations:

• wall;
• built-in;
• corner;
• hanging;
• island.

Each of these types has certain characteristics. To understand this in more detail, it is recommended that you read the information provided below.

Wall hoods. Classic version of the device. This hood is distinguished by a variety of body designs, as a result of which you can quite easily transform any room in accordance with individual requirements. It has a flat shape.

Wall mounted hood is very convenient

Built-in hoods. Installed inside kitchen cabinet, which makes them as practical and ergonomic as possible. At the same time, such hoods remain as functional as possible. Some models may be equipped with an additional exhaust plate, which, when pulled out, automatically starts the fan and turns on the lighting.

Corner hoods. Ideal for small kitchens. They have a square shape with cut corners. These variations of hoods are fixed in the very corner of the room, which allows you to significantly free up most of the wall space.

Hanging hoods. This hood option is an integral part of the kitchen furniture. It is distinguished by functionality and practicality. Installed above the stove under a wall cabinet.

Island hoods. The most versatile type of hood. It can be mounted anywhere, but most often it is installed in the center of the room. Island hoods are a good option for large kitchen premises. This element is fastened using special hangers that come with the hood. In this case, the ventilation duct runs vertically upward.

Features of installation work

Before starting installation work, you should complete whole line certain procedures. This will help eliminate the need reinstallation, which is associated with financial and time costs.

• install the hood after assembling the furniture;
• check the system for malfunction;
• take care of installing the outlet for the hood;
• define optimal height installations.

The fewer connections, the better the sealing

It is recommended to connect the hood to the ventilation system subject to certain rules. In particular, it is recommended to follow the following sequence of actions:

1. Installation of an anti-return valve.
2. Air duct connection.
3. Mounting the hood on the wall.
4. Connecting the system to the network.
5. Starting the device.

1 - channel forced exhaust, 2 - channel of natural ventilation of the kitchen,
3 - common ventilation duct, 4 - ventilation grille, 5 - check valve.

When attaching the hood body to the wall, it is necessary to seal the resulting gaps polyurethane foam. During connection of the corrugation with ventilation shaft It is recommended to ensure that the number of bends is minimal. Otherwise, the productivity of the entire system will drop slightly. Self-tapping screws are used to attach the box to the wall.

The exhaust system is connected to the network via a socket or circuit breaker. You must first connect the grounding. This will remove voltage from the case when the fan is running. On final stage carrying out the work, the hood is placed into the upper casing, after which it is completely ready for further operation.

They will be described on their own in the next article.

In the majority multi-storey buildings exists stationary system air ducts and ventilation. It has exits to each apartment in the bathroom and kitchen. Therefore, residents can connect to it and provide their housing clean air and additional comfort.

Basics vent located in the kitchen. This room is especially actively saturated with harmful, humid air generated during cooking, and fats splashed from frying. It is especially necessary to maintain a favorable microclimate and eliminate unpleasant odors. This role is played by the kitchen hood connected to common system ventilation at home or operating autonomously.

Manufacturers produce various hoods that are mounted above stoves and hobs and have access to the ventilation system. By purchasing this device, the consumer gets the opportunity to provide installation services by professionals. However, the device can be connected to centralized ventilation with your own hands, knowing the specifics of performing this work.

How does the hood work?

A kitchen hood is a simple structure. It consists of the following parts:

• engine;
• fan;
• cleaning filters.

The operating principle of the device is to create air draft. It facilitates the passage of “dirty” air through the filtration system and cleans it of impurities.

By functional features These devices come in two types.

1. Circulating hoods absorb kitchen air saturated with harmful components thanks to the draft generated by the operation of fans. Passing through the cleaning system, the air masses return back to the room absolutely clean. The circulation-type device has two filters: one traps grease and soot, the other traps odors. The first one is made from non-woven or padding polyester fabric. In some models it is replaced metal version. For long-term operation of the device, filters are changed periodically. This entails additional costs for maintaining the circulation hood and makes it less popular.
2. A flow device is considered more practical and efficient. When it works, “dirty” air from the kitchen goes outside without returning to the room. It does not use a carbon filter. It is replaced by a special grease-catching element and a layer that protects system parts from dirt and grease. Models that do not have it require special conditions care: they must be cleaned periodically. A household appliance with such an air purification system - best option for home cooking.

Features of installing kitchen hoods

The process of installing a kitchen hood with a connection to the ventilation system with your own hands depends on the type of device. Manufacturers produce different models:

• hanging;

• wall;

• corner;

• built-in;

• island.

Each of them can be circulating or flow-through.

Installing a household air purifier is not very difficult for specialists. If you want to connect it yourself, apartment owners must take into account important points.

• The most in a simple way connection of the hood with the ventilation outlet is the use corrugated pipe. It is not suitable for aesthetes, as it spoils appearance kitchens. During operation, the corrugation makes a lot of noise, which causes discomfort.

• Sometimes it is necessary to make changes to the design of the exhaust device on site, taking into account the structural features of stationary ventilation. It may become clogged or damaged due to prolonged inactivity. In this case, you will need skills in reconstructing household appliances and certain tools.
• At self-installation kitchen hood, you need to take correct measurements, take into account the height of the ceilings and the dimensions of the room, the location of the electrical outlet for connecting the air purifier power supply. This will allow you to position the cone as accurately as possible to the ventilation hole.
• When installing an air purifier with your own hands, the owner should know that a large number of connections and bends will lead to disruption of the system. A pipe connection angle greater than 90 degrees will create additional loads on the device. It may not work properly and quickly fail.

Installation and connection of a kitchen hood to ventilation

The most common option for an air purification device is to purchase and mount a wall-mounted device.

• On the surface of the wall above hob the plates measure the mounting locations of the box.

It is important to take into account the generally accepted standards for the location of the device: the distance from the lower level of the hood to the gas stove should be 75 cm, for an electric stove - 65 cm.

• Using this marking, holes are drilled into which dowel-nails are inserted.
• Self-tapping screws are screwed into them along the mounting holes in the box itself, fixing the main device.
• Next, install an air outlet pipe, aligning the hole in the box with the ventilation outlet in the wall. To do this, use a fixing clamp.
• All joints are filled with hermetic compound.

During the installation process, you must follow the instructions that accompany the device and take into account the location of the electrical outlet. It may be necessary to equip additional source nutrition.

To prevent the air purifier from spoiling the interior design of the kitchen, a built-in installation method is used. In this case, the device is mounted in a furniture cabinet equipped with doors in accordance with general design facades.

1. First on the wall according to the norm set height attach a wooden box with holes drilled in it for fastening elements and the outlet of the ventilation pipe (corrugated hose or PVC channel).
2. The device itself is inserted into it.
3. A pipe is attached to it and brought out through a hole in the furniture into the ventilation outlet.
4. A special clamp is usually sold complete with the hood, which helps secure the parts. If you don't have it, you need to buy it. It is important to take into account the diameter of both elements.
5. After carrying out and checking the operation of the device, the doors are mounted on the cabinet. They will completely hide the air purifier and the dirty air exhaust system.

Connecting a kitchen hood to ventilation with your own hands requires attention and compliance with the instructions. These nuances will allow you to create effective system air purification in living quarters.
