How to connect the hood correctly - detailed instructions + Video How to connect the hood in the kitchen to the ventilation with your own hands + video. Correct connection of the hood in the kitchen to the ventilation duct ensures a complete removal of volatile substances that are formed during cooking. Not all of them are useful and pleasant, and most of them are completely toxic, and also negatively affect the sense of smell. Believe me, no one and nothing can cope with the removal of unpleasant odors better than a hood. For those who want to connect the hood in the kitchen correctly, we suggest that you read this article, and the information in it will help you choose the type of appliance you need and ideally perform all the installation work.

All information will be useful not only for home craftsmen, but also for those who plan to control the work of hired workers.

Types of hoods

In order to improve the microclimate of the room and get rid of unpleasant odors, burning and soot, a hood for the kitchen is used. Depending on what the internal device is, it can remove exhaust air, purify it, or even work alternately in these two modes. In the first case, the device will evacuate air masses from the room into the atmosphere, and in order to do this, an air vent will be required. Models of units that draw in exhaust air and discharge it outside are easy to maintain and use.

They do not need to regularly buy expensive filters. Models of the second type are recirculating, and for their full operation it is not necessary to connect devices to the ventilation system.

For them, the electrical power is important in order to draw in exhaust air that accumulates, for example, over a frying pan. Particles of grease, odor and soot from the food being cooked will get inside the device. First, the grease filter will take a hit, and the field is the turn of the carbon filter.

The fact is that it is he who absorbs all the impurities, and then gives back the already purified air to the room, and releases it through the small holes that are in the case. A variant of kitchen appliances that can not be connected to the ventilation system is distinguished by great demands - for the equipment to work, you need to periodically buy special filters, usually coal.

For the first case of ensuring the operability of the hood, a connection to the ventilation system will be required, and for the second option, the installation of a cleaning filter will be required.

You will have to choose the required option during use, while the settings may differ dramatically depending on the model.

For example, for a LEX hood with a cleaning mode, manufacturers strongly recommend that you first install carbon filters, and then use the plugs that come with the exhaust equipment, and close the hole on the side and top, which will be designed for connection to ventilation system. The plugs will make it possible to prevent uncontrolled air exit from the inside of the unit - at first it is completely filtered, and only then it will come out through the openings that are intended for this. In addition to the principle of operation, the devices also differ in the method of installation - they can be built-in and open. They also differ in shape, on which the location of the equipment depends.

In addition, kitchen appliances differ in cost, which depends on how well known the brand is, the sophistication of the design idea, the use of materials during production and the functionality of the equipment. The buyer can easily choose the hood in the required price category, because there are decent options even in the inexpensive segment. True, the more complex the processes are available to the hood, the higher the price will turn out.

Nuances of connection

How to connect an extractor hood in the kitchen? The correct option for arranging all communications is the moment when a house is being built or major repairs in an apartment are taking place. True, with the second option, you will need to put up with the finished project or make adjustments.

When creating ventilation ducts with your own hands, you cannot connect the pipeline from the toilet, bath and kitchen into a single branch.

To install the hood to the ventilation duct, you can also use two options at once:

  • Connection to the ventilation shaft opening, which is already in the apartment.
  • Creates a duct for air flow through the wall where the equipment is to be installed.

In the first case, you will need to spend money on the purchase of an air outlet, and sometimes it will be a lot of material, and in the second you will need to make a through-type hole in the kitchen wall, which will go straight to the street. For cottages or private houses, it is typical to arrange ventilation ducts with their removal to the roof.

It is important that in this case the air intake and evacuation system is properly organized.

Work instructions

How to connect the hood correctly - detailed instructions + Video For those who decided to connect the hood themselves , you will need to first study all the recommendations that are in the instructions for the equipment, and then follow them clearly. Next, carefully examine the complete set of the device and buy, if necessary, all the missing parts. You may need clamps, air vent, sealant, adapters, or even metal tape.

Preparing the place and room

So, you need to prepare the room for future work, choose tools and buy materials.

It's good if there is already a hole for the ventilation system, because otherwise you will have to start work by making it. In addition, during the construction phase, it will be convenient to plan the placement of all kitchen appliances and make bends to connect the devices to ventilation. For example, when there is an island hood in the room, the air outlet will be removed in the middle of the ceiling. If the apartment or house has a living condition, and it will not be possible to carry out a full-scale repair, then you can simply make the missing holes by drilling in the wall or ceiling. This will depend on the specific situation and wishes.

When the hole has been made, it will be possible to install the hood over the hob. The installation method will depend on which model is chosen and where the plate is located. It is important that the device is securely fixed using the fasteners provided. Sometimes the case does not have enough holes for fixing the product, and then you can make them yourself to the required places, and then screw in the screws.

Connections to ventilation

When the hood is installed according to all the manufacturer's recommendations, it is time to connect it.

It should be understood here that for the operation of the device, a channel for the removal of waste air masses and a stable supply of electrical energy are required. If you decide to use pipes made of plastic, then you will also have to buy adapters, sealant, and you may also need to switch from round to rectangular bends of the device for the future exhaust duct. It is important that the diameter of the air outlet is not less than the outlet of the hood.

First, it is worth connecting the ventilation and the device, and this can be done using such pipes:

  • Metal corrugation - to connect the hood to ventilation, usually aluminum is used, and much less often steel.
  • Corrugated plastic - is used very rarely.

  • Stainless metal with a round cross section.
  • Plastic with round / rectangular section is also quite a convenient and popular option.

When selecting a corrugation, you may need a clamp, a lattice for entering a common house channel, metal tape, and the connection is carried out in stages. Well-made connections will ensure excellent operation of the device, but the work is not over yet - you cannot use the hood for now. It remains to start the motor, and for this you need to supply electrical power, and then put on a decorative casing.

To do this, you need to follow a specific queue of work. Make sure in advance that the line to which the connection will be connected is de-energized.

If the hood has wires, then they must be connected to the power cable clearly according to the diagram, which is applied next to the body. For this, it will be convenient to use PPE caps.If the hood has a plug, then it will be enough to insert it into an outlet that is located nearby, and it is good when an electrical point is provided for the hood in advance, which is located directly behind the air outlet.

Next, it remains to measure the length that the protective box should have and hide everything else. This is usually easy to do - just slide everything you don't need inside. You need to hide electrical wires behind the box, fasteners - from the outside the case and the path to the channel entrance will look like a single whole.

When the connection is complete, it remains to check the build quality, and for this, turn on the equipment and select all speeds in turn. Turn on the backlight and measure the noise generated by the device.

Check all this against the indicators that are indicated in the instructions.

Completion of installation work

Not always connecting to electricity and ventilation is the final stage. Sometimes the entrance to the mine is located very inconveniently or far away and you need to turn on your imagination in order to somehow disguise everything. It is definitely worth planning everything in order to choose the best option for masking the air duct, because the implementation of some ideas requires additional expenses. The cheapest and easiest option is if the hole is located nearby - the hood of the hood will hide the place of the inset into the ventilation system.

It's also nice if it's close to the entrance to the mine, and then you can buy a plastic pipe that matches the color of the rest of the furniture in the kitchen.

Operating standards and rules of care

Conditions of use and regular service are the key to longevity in operation. It is not surprising that devices with a warranty period of 1-2 years, if all the rules are observed, work perfectly for 7-10 years, and at the same time, often without requiring expensive repairs.

Safe use of the hood

In order for the device to work without problems in the kitchen, it should be correctly installed at the very beginning and connected to all necessary communications - ventilation and electricity. There should be no distortions.

During the turn-on test, the device will operate quietly, with the noise level acceptable according to the instructions. Cracking, creaking and other extraneous sounds are witnesses that you made an error when installing. Immediately after installing the unit, check its noise and performance. You can use real noise meters if you have one, or a smartphone app.

It is categorically unacceptable to use household exhaust devices in production - it is possible only for their intended purpose, since otherwise the owner will automatically lose the warranty.

Moreover, the following is prohibited:

  1. Cover / plug openings on the device body.
  2. Restrict / shut off free air flow during operation.
  3. Connect the air duct to the exhaust duct for smoke and other heated emissions.
  4. Carry out repair manipulations or service the hood without disconnecting the hood from the electrical network.

Such prohibitions are related to the safety of users and equipment

This - violation of the rules may lead to failure of the fan, and without it the device cannot will be able to work.

If the final stage of cooking is flambé for an appetizing steak, in order to convey to it the notes of aged cognac, follow the process very carefully so that the fat filters do not catch fire.


When you are familiar with the rules for carrying out work when connecting the exhaust equipment to the ventilation system, you can try to make the connection yourself. An exception would be a recommendation from the manufacturer of a household appliance, which is advised to carry out installation and communication with the involvement of specialists. In this case, in order not to lose the warranty on expensive equipment, it is better to pay for the services of a master to connect the device and not risk it.
