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

The kitchen is considered one of the most important rooms in a city apartment or a private house. Here, you need to provide everything correctly so that the hostess can cook food comfortably. Particular attention should be paid to the hood. This appliance is used to remove water vapor and odors that are released during cooking. From our article, we learn how to connect a hood in the kitchen to ventilation.

Cooker hood: types and principle of operation

The connection method as well as the operating characteristics depend on the type of device. There is equipment that operates in automatic mode without forcing a fan.

Classic appliances remove contaminated air through ventilation ducts. Modern models pre-clean water vapor from harmful substances and odors, and only after that there is an emission of flows into the atmosphere. Combined models can operate in two modes - for exhaust air or filtering.

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

1. Built-in models are mounted in the kitchen. These are devices of the classical or recirculation type.
2. Hanging equipment is mounted directly above the hob. These are mainly recirculation type systems.
3. Wall-mounted models are mounted above the gas stove, mounted on brackets or wall plugs to the wall. Devices are used for filtering 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 classical or combined type.

The connection of the cooker hood to the ventilation duct may differ depending on its structure and location.

Hood installation requirements

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

• The overall dimensions of the equipment should repeat the hob. Only in this case is the effective removal of odors.
• When mounting between a gas stove and the lower protruding part of the equipment, a distance of 50-60 centimeters is left. The main condition for installing the device is the convenience of the housewife during 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 will ultimately lead to spontaneous combustion.
• It is necessary to choose the right device, its power should be enough for a 10-fold change of air 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 are compared with the performance of the device.

How to connect the hood in the kitchen to ventilation in the absence of a channel? 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 power.

Ventilation features

When installing the hood, you need to choose the right 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 possibility of changing 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 this product is the creation of noise during the passage of air flows. In addition, grease, dust and dirt are constantly deposited on the surface of the corrugated sleeve. It needs periodic cleaning from pollution.
2.  A round plastic duct is assembled from several parts (adapters, angles and couplings). The connection of all parts is carried out by fittings. To prevent tears, the joints are coated with special glue, then additionally fixed with screws. The main advantage of such a system is silent operation.
3.  Square plastic ventilation ducts are made of polyvinyl chloride. The product in question has the same characteristics as the previous view.

The package of plastic models of ducts includes additional parts with which you can install the most complex engineering systems. Such products are notable for their high cost and complex construction, their installation should be carried out by a professional.

What should be the duct

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

Plastic

Plastic pipes have a minimum weight, they have a good level of sound insulation, are quickly mounted. 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 over hanging cabinets. At the time of purchase of such products, purchase additional parts, reducers, bends, as well as sealant.

Corrugation

Corrugated 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 flows. Additional fastening elements for mounting such an air duct are not needed; it is fastened with clamps. If necessary, aluminum corrugation can be stretched and bent.

 What tools will be required

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

• corrugated aluminum or plastic duct;
• distance measuring tape;
• pencil or marker;
• metal square;
• jigsaw is used for making holes;
• screws;
• bolts
• keys set;
• sealant;
• screwdriver;
• clamps for securing the corrugated air duct.

After preparing the tool, you can begin the basic work.

Connection steps

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

At the preparatory stage, they close the furniture with plastic wrap and punch a hole for the hood in the ceiling or wall, depending on the type of appliance. In the buildings under construction, a hole in the kitchen is planned at the construction stage. After making 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 how it is fixed. Some models do not have fixing holes. In this case, they are made independently and screwed in.

After installing the hood according to the manufacturer's recommendations, we proceed to connecting the device to the duct. For the proper functioning of the device, a source of electricity is required, as well as a ventilation channel for exhausting exhaust air. We connect the hood to the pipe. This can be done using the following details:

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

If the choice fell on the corrugation, then to fix it, you will need a collar of the desired diameter or metal tape. For proper uninterrupted operation of the device, it is necessary to correctly connect the hood to the corrugation or pipe. For sealing, 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. From the surface of the gas stove to the lower edge of the hood, leave a distance of at least 90 centimeters. If the household appliance is electric, then the size is reduced to 70 centimeters. When fixing the corrugation or pipe in the ventilation channel, you need to install a special grille that will prevent the opening of the hole. The design of the device has a special valve that operates during the removal of contaminated air. If the device is not turned on, the valve closes, which will ensure a natural exhaust gas discharge.

The range hood and accessories must 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 corresponds to the shade of the headset. To mask the ventilation system, thin plastic products are used.

We learned how to draw a hood for ventilation. Now you can start the engine and put a decorative cover on the product. At the final stage of work, connect the device to the network and check its performance. Let's talk about this in more detail.

Connect the kitchen hood to electricity

Even a beginner can cope with work, but some nuances in this matter are still present. In some cases, the hood does not reach the nearest outlet. The main solutions to the problem are the use of carrying, lengthening the cable or moving the outlet to a new location.

It is not practical to use a long cord, but even if the choice fell on this option, the cable must be fixed to the surface of the walls and connect the plug to the nearest outlet. The most popular way out of the situation is to install an outlet. This element is preferably disguised as a kitchen set.

The main aspects of the operation of the hood

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

1. Follow the device during its operation, check the degree of heating of the case.
2. Keep children away from the appliance.
3. At intervals of 2-3 months, check the filter, clean it of fat deposits. Such contaminants can cause spontaneous combustion of the product.
4. Do not operate the hood without a filter installed.
5. Do not ignite a gas burner without cookware installed; an open flame can cause fat in the filter to ignite.
6. In the event of a device breakdown, do not repair it yourself, resort to the help of a wizard.
7. Do not use chemicals with abrasive particles to clean the hood. They may scratch the surface of the product.
8. Simultaneous continuous operation of two high-flame gas burners is not permitted. Continuous exposure to open flames causes the surface of the appliance to overheat.
9. To prevent electric shock, clean the appliance only after turning it off from the power 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 yourself, carefully read the instructions and only then proceed with specific actions.
