How to connect the hood in the kitchen to ventilation: instructions

The kitchen is considered one of the most important areas in a city apartment or private house. Here you need to foresee everything correctly so that the hostess can comfortably prepare food. Pay particular attention to the hood. This appliance is used to remove water vapor and odors that are generated during cooking. From our article we will learn how to connect the hood in the kitchen to ventilation.

Kitchen hood: types and principle of operation

The connection method as well as the performance characteristics depend on the type of device. There is equipment that works in automatic mode without the forced switching on of the fan.

Classic devices remove polluted air through ventilation ducts. Modern models pre-purify water vapor from harmful substances and odors, and only after that flows are released into the atmosphere. Combined models can operate in two modes - for exhaust air discharge or filtration.

There is the following classification of hoods according to the installation method:

1. Built-in models are mounted in a kitchen set. These are devices of the classic or recirculation type.
2. The hanging equipment is fixed directly above the hob. These are mainly recirculation-type systems.
3. Wall-mounted models are mounted above the gas stove, attached to brackets or dowels to the wall. The devices are used for filtration or direct discharge of exhaust air.
4. Island models can be located anywhere in the kitchen, they are attached to the ceiling. These are systems of the classic or combined type.

The connection of the kitchen hood to the ventilation duct may differ depending on its design and method of location.

Hood installation requirements

The hood must be connected to ventilation according to the following rules:

• The overall dimensions of the equipment must match the hob. This is the only way to effectively remove odors.
• During installation, a distance of 50-60 centimeters is left between the gas stove and the lower protruding part of the equipment. The main condition for installing the device is considered to be the convenience of the hostess while cooking, so the hood cannot be installed below the specified size. In this case, the equipment will overheat, grease and dirt can accumulate on its surface, which ultimately will lead to spontaneous combustion.
• It is necessary to choose the right device, its capacity should be enough for 10-fold air changes in the room for an hour. To calculate these indicators, it is necessary to determine the volume of the room by multiplying the length, width and height. The data obtained is compared with the performance of the device.

How to connect the hood in the kitchen to ventilation in the absence of a duct? In this case, it is necessary to select equipment with air recirculation and the ability to change performance. Such devices should not work for long at medium capacities.

Ventilation features

When installing the hood, you need to choose the right air duct. In practice, the following types of ventilation systems are used:

1. Corrugated sleeve made of aluminum. The main advantage of such a model is the ability to change the shape for acceptable parameters. The material bends well, which makes it possible to make a ventilation duct with turns in the right places. The disadvantage of the product is considered to create noise during the passage of air currents. In addition, grease, dust and dirt are constantly deposited on the surface of the corrugated sleeve. It needs periodic cleaning from contamination.
2.  A round plastic air duct is assembled from several parts (adapters, corners and couplings). The connection of all parts is carried out at the expense of fittings. To prevent ruptures, the joints are coated with special glue, then additionally secured with self-tapping screws. Silent operation is considered the main advantage of such a system.
3.  Square plastic ventilation ducts are made of polyvinyl chloride. The product in question has the same characteristics as the previous form.

The complete set of plastic models of air ducts includes additional parts, with which you can install the most complex engineering systems. Such products are distinguished by their high cost and complex design; a professional should be engaged in their installation.

What should be the duct

Before connecting the hood to ventilation, you need to understand the types of air ducts that can be used for this purpose.

Plastic

Plastic pipes have a minimum weight, they have a good level of sound insulation, and are quickly installed. Products made of polyvinyl chloride have a round or square cross section. Installation of such a ventilation duct is carried out in the upper part of the kitchen set above the wall cabinets. When purchasing such products, purchase additional parts, transition couplings, bends, and sealant.

Corrugation

Corrugated air ducts are considered the most budgetary option for a ventilation system. Such products are made of aluminum, have thin ribs, which stimulates the creation of sound during the passage of air currents. Additional fastening elements for the installation of such a duct are not needed, it is fastened with clamps. The aluminum corrugation can be stretched and bent as needed.

 What tools are required

Before connecting the hood to the ventilation in the kitchen, you must prepare the following tools and materials:

• corrugated aluminum or plastic duct;
• tape measure for measuring distances;
• pencil or marker;
• metal square;
• jigsaw is used for making holes;
• screws;
• bolts;
• a set of keys;
• sealant;
• screwdriver;
• clamps for fixing the corrugated air outlet.

After preparing the tool, you can start the main work.

Connection stages

Users who do not know how to connect the hood to ventilation should carefully study the manufacturer's requirements, which are indicated in the instructions for the device. After that, the equipment is inspected and the missing parts are purchased, for example, clamps, sealant, adapters or metal tape.

At the preparatory stage, the furniture is covered with plastic wrap and a hole for the hood is punched in the ceiling or wall, depending on the type of device. In buildings under construction, a hole in the kitchen is planned at the construction stage. After opening the hole, the hood is securely fixed over the stove. For this purpose, you can use dowels or special brackets, it all depends on the type of device and the way it is fixed. Some models do not have fixing holes. In this case, they are made independently and self-tapping screws are screwed in.

After installing the hood according to the manufacturer's recommendations, we proceed to connecting the device to the air duct. For the device to function properly, a source of electricity is required, as well as a ventilation duct to discharge the exhaust air. We connect the hood to the pipe. This can be done with the following details:

• aluminum or steel corrugation;
• round or square plastic pipes;
• corrugation from stainless steel.

If the choice fell on the corrugation, then to fix it you will need a clamp of the required diameter or metal tape. For the correct uninterrupted operation of the device, it is necessary to correctly connect the hood to the corrugation or pipe. To seal, coat the joints with silicone, if necessary, bend the pipe and release its other end into the ventilation shaft.

During the main work, monitor the parameters. Leave a distance of at least 90 centimeters from the surface of the gas stove to the lower edge of the hood. If the household appliance is electric, then the size is reduced to 70 centimeters. When fixing a corrugation or a pipe in the ventilation duct, you need to install a special grate that will prevent the hole from blocking. A special valve is provided in the design of the device, which is triggered when the polluted air is removed. If the device is not switched on, the valve closes, which will allow the natural removal of exhaust gases.

The cooker hood and accessories should be in harmony with the existing kitchen environment. To achieve this, the corrugation or pipes are hidden in a protective casing, the color of which matches the shade of the headset. To mask the ventilation system, thin plastic products are used.

We have learned how to conduct a ventilation hood. Now you can start the engine and put the decorative cover on the product. At the final stage of work, the device is connected to the network and its operability is checked. Let's talk about this in more detail.

Connecting the hood in the kitchen to electricity

Even a beginner can cope with the work, but some nuances in this matter are still present. In some cases, the extractor cord does not reach the nearest outlet. The main options for solving the problem are considered to be the use of a carrier, lengthening the cable or moving the outlet to a new place.

It is impractical to use a long cord, but even if the choice fell on this option, then the cable must be fixed on the surface of the walls and connected to the nearest outlet. The most popular way out of the situation is to install an outlet. It is desirable to disguise this element as a kitchen set.

The main nuances of operating the hood

When using the hood, the following rules must be observed:

1. Watch the device during its operation, check the degree of heating of the case.
2. Keep children away from the appliance.
3. Check the filter at intervals of 2-3 months, clean it from fat deposits. Such contamination can cause spontaneous combustion of the product.
4. It is forbidden to operate the hood without the installed filter.
5. Do not light a gas burner without cookware installed, an open flame can ignite the grease in the filter.
6. If the device breaks down, do not repair it yourself, resort to the help of a specialist.
7. Do not use abrasive chemicals to clean the hood body. They can scratch the surface of the product.
8. Simultaneous long-term operation of two burners of a gas stove with a high flame is not allowed. Prolonged exposure to open flames causes the surface of the device to overheat.
9. To prevent electric shock, clean the appliance only after unplugging it from the wall outlet.

For the smooth operation of the ventilation system in an apartment or a private house, entrust the installation of the hood to specialists. When installing the device with your own hands, carefully read the instructions and only then proceed with specific actions.
