Installation of built-in hood: location options and installation instructions

When equipping kitchen premises, the owners are increasingly attracted to such an option as a built-in hood.

This is an effective and compact element that can be disguised among the rest of the furniture to make the interior of the kitchen more harmonious.

How does this technique

This type of hood is often chosen for a kitchen with a small area, since it has a compact size. Of course, the purpose of the device is not limited to the problems of interior decoration. First of all, it is necessary to clean the air from unwanted impurities that arise in the process of cooking.

The presence of the hood allows you to quickly remove from the room odors emanating from cooking food, vapors, pollution, etc. Embedded version fulfills all these requirements, and also has a compact size and a small amount of noise emitted during operation.

The disadvantages of such devices include a high price, which is fully compensated by solid advantages. For small sizes, the device has the necessary level of performance. There are horizontal and vertical hoods. The most common are the first, since they are much easier to install.

Advantages of the built-in hood
One of the advantages of the built-in hood is its compact size and minimalist design that will fit well into the interior of any kitchen.

The device can be mounted in a wall cabinet or a special box. With the vertical option, everything is a little more complicated, it needs to be installed right in the wall, in a niche made for this purpose. The manufacture of this niche greatly complicates installation. When choosing a hood, you need to focus not only on its type, but also on the size of the hob.

Built-in hood dimensions
The width of the retractable part of the built-in hood must match the width of the cabinet in which this device will be installed

The width of the device can vary in a fairly wide range: from 45 to 90 cm. It should be remembered that the working width of the hood should be as close as possible to the dimensions of the hob. Only if this rule is observed can the device be sufficiently effective.The most popular model is 60 cm.

An important element of the built-in model hood is a filter for trapping fat. The horizontal hood must be pulled out before switching on so that it is located over the entire area of ​​the cooking surface. The fat filter is located exactly in this moving part. Some models are equipped with an optional air recirculation feature.

Flow and circulation hoods
Flow hoods completely remove exhaust air from the kitchen, and circulation devices clean it and leave it in the room.

Such devices must be equipped with a carbon filter, they are more expensive. They can operate in two modes: lead or recirculation. It is necessary to determine the type of hood even before furniture is made in the kitchen, since the cabinet in which the device will be installed must be of suitable size.

Hoods with recirculation are good because they return to the room not only purified, but also warm air. Thus, a significant part of the heat energy spent on cooking and heating the air will remain within the house. However, flow hoods clean the air better.

Another important parameter when installing such a hood is the vertical distance from the cooking surface to the edge of the hood, i.e. to the bottom of the cabinet in which it is embedded. This parameter is strictly normalized, for electric stoves it should be 70 cm, and for gas - 80 cm.

The distance from the hob to the hood
The distance from the hob to the hood should be at least 65 cm and not more than 85 cm

Failure to comply with this requirement will lead to a noticeable decrease in the efficiency of its work, it is possible that the device will break. In some kitchens it is not possible to install the hood at a distance of at least 85 cm from the hob. In this case, it is necessary to purchase a structure with a higher capacity than the calculated one.

There are plastic air ducts with square and round sections. Round designs are used less frequently than rectangular counterparts, since the latter occupy much less space than a cylindrical channel. It is preferable to use exactly the plastic version with smooth walls, because they are better resist the accumulation of dirt.

Air duct of the built-in kitchen hood
The air duct of the built-in kitchen hood should not be too long, it is recommended to make no more than three turns in order not to impair the operation of the appliance

The corrugated air duct in this plan will create more problems, besides, with the passage of hot air through such a channel an additional amount of noise is formed. The maximum permissible level of sound interference that hoods can produce is 70 decibels. This is a little louder than the sound in the process of a normal conversation.

Despite these shortcomings, corrugated air ducts are widely used with exhaust hoods, as they also have advantages. It is simpler to mount such a construction, since it can be tilted and bent appropriately. Therefore, for successful installation will not need adapters or additional elements.

Corrugated Duct
As an air duct for a built-in hood, you can use a special corrugated sleeve. It is easier to install, but may produce more noise than plastic counterparts.

But to turn the plastic duct you need to create a special knee. This design contributes to the formation of turbulence of hot air inside the channel, which is not very useful. To reduce the amount of dirt on the walls of the corrugated duct, stretch it a little while installing the recessed hood.

If desired, a circular cross section of this design can be made square, so that the duct takes up less space. This is another advantage of structures of this type. Good quality is demonstrated by such models of built-in hoods as Bosch DHL 545 S, Shindo MAYA 60 SS / BG, Elica KREA GFA WH / F / 60, Miele DA 2270, Sub-Zero Wolf and others.

Performance, filters, management

According to sanitary standards for kitchen premises, tenfold air exchange is recommended for each hour. Therefore, when calculating the performance of the hood should focus on the volume of the kitchen, expressed in cubic meters. To do this, multiply the length, width and height of the room, and increase the result by ten times.

For example, for a kitchen with an area of ​​three by four meters and a ceiling height of three meters you will need an extractor with a capacity (3 m X 4 m X 3 m X 10) 360 cubic meters per hour. And this is the minimum value. Experts recommend taking a kitchen hood with a certain amount of power. If the performance of the device will be lower, it simply will not cope with cleaning the kitchen air from pollution.

Grease filters vary in composition as:

  • organic (on the basis of a synthetic winterizer);
  • paper (on the basis of flizelin);
  • synthetic (based on acrylic);
  • metal (aluminum or steel).

Paper filters are a one-time option, they need to be replaced each time with new ones when they become dirty. Synthetic analogues can be washed, but it should be done very carefully, because they are easy to damage. From time to time they will also have to be replaced, although not as often as paper ones.

Metal filters are considered the most reliable, they are wear resistant cassettes. Coal varieties that are used only in recirculation plants are also not cleanable. They need to be replaced in a timely manner, otherwise the performance of the hood can be significantly reduced.

When choosing a hood, you should pay attention to its type of control. Electronic control usually allows you to:

  • automatically adjust the level of performance;
  • change modes of operation;
  • configure the device to turn on and off in automatic mode;
  • the inclusion of built-in lighting in the presence of movement near the stove;
  • light indication of the status of filters, etc.

Among the useful functions of the built-in hood in the cabinet, it is possible to note the residual stroke mode: the fans operate for some time after turning off the hood,to ensure maximum removal of contamination. The mode of additional ventilation allows you to automatically run the hood at low power at regular intervals to maintain optimum air exchange in the kitchen.

How to install

It is necessary to begin installation from furniture into which the extract will be built in. If the cabinet fits in size, then it is possible to continue the installation in normal mode, simply by making the necessary holes in the furniture, but this is not always possible. A small device with parameters of 50-60 cm is usually placed in a standard kitchen cabinet.

Built-in hood options
Before installing the hood, you should carefully examine all the dimensions and parameters in order to properly select the necessary elements and make the appropriate connectors.

If this is not the case, then the owner of the kitchen has two options: order a new furniture or dismantle the cabinet in order to use a special box for the hood. The latter option has certain advantages, since the box is assembled separately at the bottom, then the hood is fixed in it and only after that the entire structure is installed on the wall.

Hood box
It looks like a box in which set the hood. The construction is assembled separately, then attached to a wall or to furniture, which is more convenient than putting the device directly into a cabinet.

On top of the hood install the facade, so the exterior hood looks neat and stylish. The problem of insufficient space can also be solved with the help of a device of minimum size - 45 cm. Such a model can be placed even in a very small cabinet. But it should be remembered that compact dimensions in this case are obtained at the expense of performance.

It is necessary to take into account this moment so that it does not work out that a suitable exhaust hood does not cope with the required amount of work. If the cabinet fits in size, in its bottom you need to make a hole for the hood, taking into account its size. Sometimes it is more convenient to completely remove the bottom. In the upper part of the cabinet you will also need to make an opening for the duct.

Air duct hole
In the upper part of the cabinet, designed to install a built-in hood, you need to make a round or square hole under the duct

It can be round or rectangular, it all depends on the type of duct.Often, flexible corrugated structures with a circular cross section are used, but plastic ventilation ducts with a rectangular or square cross section are also encountered. An air duct connects the hood with a hole in the wall leading to a common ventilation duct in an apartment building or directly into the street when it comes to private building.

Another cutout will need to be performed on the back of the cabinet to secure the device and install the outlet. After all the necessary openings in the cabinet are ready, you can proceed directly to the installation of the device. First, the hood is fixed in a locker or box. At the same time, you should make sure that the movable part of the device is freely extended to the required width.

Built-in hood
Part of the built-in hood is extended so that it covers the entire surface of the plate. Only such a position will effectively clean the indoor air.

After that, the duct is fixed to the connector in the upper part of the device with a clamp. Experts recommend making this mount detachable, so that there is an opportunity for easy dismantling. Some masters immediately use sealant, but professionals do not always approve of such a decision.

Partition for built-in hood
In order for the built-in hood to be located in the cabinet correctly, it may be necessary to install an internal vertical partition, which is recommended to be removable.

Periodically, the structure will have to be disassembled in order to clean it of fat accumulations and other contaminants. However, it should be remembered that the connection must be sufficiently tight to ensure effective removal of polluted kitchen air. Most often, the exhaust duct draws their cabinet vertically, but sometimes they use a side tap through the back wall. In this case, the hole is made from behind.

You should not make a hole “not the peephole”, you should first apply the markup. Some models of hoods are equipped with a convenient template that greatly simplifies the process of marking the floor mounting for the device. If there is no such template, it is necessary to perform markup in the usual way, i.e. using roulette and construction level. Hood must be installed strictly horizontally.

Installation of the built-in hood is usually done after the entire kitchen unit has been assembled so that the whole structure is comfortable and looks neat.As a fastener for the hood is usually used screws with dowels. After installing the hood in the box in the appropriate hole install a special adapter to connect the duct. After that, it remains to bring him into the ventilation duct.

The duct for exhaust must be as short as possible, since this indicator affects the overall performance of the device. The maximum allowable number of knees is three.

These points should be taken into account even at the stage of general design of kitchen design; it is recommended to install the stove as close as possible to the common ventilation duct of the house. The diameter of the duct should be the same as the size of the intended pipe for it. Usually this indicator is 120 mm or more.

Exhaust power cable
Take the power cable up so that it does not overheat near the cooking surface. On the back wall of the cabinet they usually make a socket.

An important point - the choice of the correct position for the power cord. It must not pass directly above the hob. The cable must be fixed inside the cabinet, and the socket for its connection must be installed in the area of ​​the back wall, in which the hood is installed.You can choose another place for the outlet, as long as this part of the device does not overheat when the plate is turned on.

After all the installation work has been completed, connect the device to the power supply, extend part of the hood and test its operation. The ventilation of the kitchen room can be done with an exhaust fan, but if the hood is already installed in the room, the use of additional devices is considered unnecessary.

Here is some useful information about replacing carbon filters:

The hood, which can be hidden behind the furniture facade - the perfect choice for almost any kitchen. Such a device produces little noise, does not spoil the interior and can be installed by one person in just a couple of hours. If the hood is correctly chosen, and its installation is completed without errors, it will provide the necessary air exchange for the kitchen.
