Can I connect the hood in the kitchen to the ventilation and how to do it

To connect the exhaust to the ventilation riser, you need to act according to the rules. We tell how to install and connect the system with your own hands.

Before connecting the exhaust in the kitchen to ventilation, you need to consult with engineers and find out the throughput of the pipeline. Connection can be done with your own hands. There is nothing complicated in this. The hole is cut in the rudder, it is mounted for a tight nozzle. The junction is sealed. It should be borne in mind that in most urban apartments such a decision is prohibited by law. The fact is that the general channel is not designed for additional streams. Without the forced delivery devices, it will be weak, especially in summer, when the pressure drop inside and outside the building is small. Rotating blades will create a powerful jet, overloading the central system. As a result, the exhaust air will go into neighboring apartments. Such a problem occurs in private buildings with an insufficient section of the air duct. To decide it, you need to make an outdoor outline through a wall valve or use models, filtering pollution and returning purified flow into the room.

What to do in case of prohibition

In which cases, the cut in the general ventilation channel is not possible

According to the current regulations, it is prohibited to carry out work, after which the living conditions are worse.

In the Buildings of the Typical Series section, the riser does not allow the use of powerful gas removal equipment from the stove. In addition, in many houses, the pipes are in unsatisfactory condition. As a result of illegal redevelopment, the cross section decreases below the normative, and its throughput drops. In addition, some tenants have already installed fans. If you build another one, the thrust starts working in the opposite direction.

After unauthorized actions, the spent gas applies to the nearest floors. Notice it is easy. Foreign smells appear in the dwelling. Air becomes raw. Black spots of mold are formed on the walls. In the room there is uncomfortable, and to get rid of the stuffiness, you have to constantly hold the windows open.

If you apply a sheet of paper to the vent's lattice, it will be dismissed in the direction where the stream moves. Ideally, he must stick to the lattice. With faulty work, it will remain motionless or bent towards the room.

When the neighbors detect the problem, they will most likely turn into a control company. Experts will examine, and when analyzing will be discussed with the requirements of standards. GOST and SNIVA presented high requirements for air quality and its circulation. In case of violation, the connection of the drawing in the kitchen to ventilation will have to be dismantled.

Restrictions on the installation that do not depend on the capacity of the central general mine

• Forced feed cannot be used in kitchens with gas stoves.
• It is forbidden to completely overlap the entrance to the riser - it must serve not only the kitchen equipment, but also the entire apartment.
• You can not withdraw the system in the riser on the lower floors.
• The inlet at the top of the box should remain in its place. Any changes to their position require coordination in housing inspection and other government instances. It is not allowed to pull the hole down, since the saturated streams are always concentrated from above. Indoor with a gas stove such a reorganization can lead to a dangerous cluster of natural gas under the ceiling.

In other cases, the reorganization is possible only in modern houses with extended channels. Before buying equipment, it is necessary to consult with specialists from engineering firm and conduct a survey.

In private buildings that are objects of Izhs, the same standards are valid as in multi-unit.

Choosing equipment

Composite parts of the drawing

• Dome over a stove, suction used air. It is attached to one or two walls. Island models hang on the ceiling.
• Air duct - plastic or corrugated aluminum. His structure is carefully thought out before connecting the exhaust to ventilation in the kitchen.

Types of devices on the principle of system operation

• Recycling - the air is cleaned in the filter, located inside the case, and is fed back to the room.
• Flowing - they are connected to a riser or wall valve. The filter is built into the housing over the blades. It is needed so that the pipe is not clogged with fat deposits.
• Combined - both principles are combined in them.

We will consider the first option.

Design of domes

They differ in form and device.

• Cone or pyramid - installed between the cabinets or in a spacious high niche.
• Hidden system is placed at the bottom of the mounted cabinet. The control panel is transferred to the facade. The space behind it takes the removal. The upper part, where there is a narrowing, is often equipped with shelves.
• Sliding - can rise and descend. Usually it is hidden behind the facade.
• Design in the form of an inverted letter "T".
• The ceiling model in the form of a parallelepipeda is used for kitchen islands.

The size of the lower part should be greater than that of the slab, a few centimeters. The working height ranges from 65 to 75 cm. For gas plates take a height of up to 85 cm.

The material of the dome does not affect its durability. The difference is the simplicity of service. Care for aluminum corps is easier than others. Dirt is easily removed with a wet sponge. In plastic, it is eaten deeper. Steel is easily dirty. To wipe tempered glass, you will need a special cleaning composition.

The equipment is selected by productivity. What it is higher, the faster the air will be cleaned. Models with powerful electric motors consume a large amount of energy and takes a lot of space, so it is better not to mount them in small rooms.

Selection of eyelid

• Aluminum corrugation is characterized by flexibility that allows you to make turns in the right places. Ribbed surface detains the flow and quickly saves dirt deposition. It is very difficult to clean it. Metal well resonates and strengthens noise when working.
• PVC pipes - they consist of several straight and rotary elements bonded with glue and clamps with screw clamps. Round cross-section products have a higher conductivity. The average diameter is 12.5 cm. Rectangular details helps save space. Standard dimensions - 20.4x6 cm.

Instructions for the output in the kitchen in ventilation

Preparation of the foundation

Works, as a rule, begin after installing furniture and finishing. The base should be reliable. If the mount is carried out on the finish, it is important not to damage it. To make the tile not cracked, the back side of the body is covered with damper ribbon.

The surface is purified and treated with antiseptics that prevent the appearance of bacteria. Mold can be formed in the gap between the wall and the case. In these areas, moisture and sediment always accumulates, which brings couples with him.

Walls do not always have sufficient bearing capacity. If they are creepy, they do wide holes and drive plugs. Sometimes these measures do not help. Then the base is wetted with water and fill the cement mixture. While she did not froze, dowels are plunged into it. After that, it is possible to install, without fear that the system will fall on the stove.

Installation work

They are starting with the attachment of the dome on the self-tapping screw with dowels. Then it is connected to the channel leading to the mine. Its end is labeled with glue or sealant and put on the top of the case. The joint is fixed by a clamp that is tightened by the screw. In the same way, plastic straight and corner tubes are connected.

The channel is mounted to the ceiling on metal suspensions or staples, pressed it to the wall. In a mine under the ceiling with a diamond crown, a hole of the suitable diameter is dried. The flange will be screwed to it. In it, if necessary, the adapter is attached. The adapter is a sleeve covered with glue or sealant. The clamp is tightened from above. There are special t-shaped elements with a check valve. The grille is made under it. It must necessarily be downstairs. If you move it upstairs, the thread from the exhaust, rising upstairs and the test pressure, will come back through it. The lower crossbar of the letter "T" is located in parallel with the wall. One side of the upper crossbar will start in the mine, the other, facing the kitchen, is supplied with a swivel flap. When the supply device is turned on, the damper closes. When the feed is turned off, it is open, increasing the input width in the riser.

When designing, turns should be avoided. Than they are less, the less obstacles to the flow, and the easier it is to produce the cleaning of the inner surface. To smooth out cool turns, instead of a g-shaped adapter put two elements with a bend under 45 degrees.

The channel is left in front of either hide it under a removable drywall or plastic box. To get rid of excess noise, the box from the inside is filled with mineral wool or foam rubber. In the case when the eyeliner is not visible for furniture, disguise activities will not be required.

Electrical equipment

For connecting the electrician, kitchen sockets are used with a protective shutdown device and a three-core cable for WGN-LS 3 * 2.5 mm2. Sockets put in the top of the wall. Use extension cords in a wet environment is prohibited. Wires hide behind the facade panel. It is usually not necessary to lay stages. If such a need arises, it should be remembered that the wall panels and overlap plates are prohibited. The gutter is allowed to lay in the finishing layer. If you plunge into reinforced concrete more than 1 cm, you can damage or barb fittings. When contacting the external environment, it will begin to rust and collapse quickly.

How to improve cravings

One of the conditions providing normal traction is the constant flow of fresh air instead of the discrepania. In winter, it is difficult for the problem to solve frequent ventilation through the vents and framugs, then the apartment will be too cold. One of the solutions is a wall or window trim valve. Walls are produced with an adjustable flap and thermal insulating inner shell. Window crashes into the upper part of the glass frame. There are special flaps with inner channels. Air from the street enters the gap on the upper side of the frame. The cold stream is lowered by profile, gradually heating from its body, and leaves below.

There are devices that are connected to the instruments measuring the temperature and humidity in the room. They can be programmed to maintain a specific climate regime. In the kit there is a timer.

What to do if you can make a cut in the riser

In this case, there are two options - the removal of gases into the street through the hole in the wall and the use of recycling systems.

Installation of a wall valve

You can not apply this method. Before purchasing equipment, it is necessary to consult with representatives of the engineering company. There are several restrictions that can not be taken into account before making an exhaust to ventilation in the kitchen.

According to SP 54 13330.2011, the use of wall devices for the forced removal of exhaust air is allowed. It also says that the distance from it to the neighborhood windows should be at least 8 m. In most homes, kitchen windows are located next to neighboring, which makes the use of wall systems impossible. In the summer, when carrying out, the smells will penetrate into the adjacent window. A layer of fat deposits will appear on the windows.

To solve the problem, you can install powerful filters that cleanse the spent stream. However, in this case, it is easier not to punch a hole in the wall, but to send the air back into your apartment.

Grid outside well noticeable. In homes, which are architectural monuments, its installation will be banned, otherwise the facade will lose its appearance.

If the conditions allow, the valve is connected using plastic pipes and aluminum corrugations. One should not pierce the channel by the perforator - after it remains the spied edges, requiring sealing with cement mortar. In addition, when blowing a perforator in the bearing structures, cracks may appear. It is better to use a diamond crown - it leaves perfectly smooth edges. The diameter can be chosen according to the size of the case.

Recycling systems

They work as efficiently as the discharge gas from the room. When they are installed, it is not necessary to solve the question of how to connect an exhaust with ventilation in the kitchen. The gasket of air ducts is not required, which greatly simplifies the installation. There are no prohibitions for use. The project does not have to coordinate. Installing the case and its dimensions do not differ from the previous options. The absence of an outlet tube from above helps to save space for a furniture facade.

The only drawback is to change the filters, so sometimes it is more expedient to make an exit to the mine or outside.
