Do-it-yourself hood installation in the kitchen is carried out depending on the type of construction.

The efficiency of the device depends on how correctly the device is selected, and then the rules that ensure installation are already in force.

Classification of modern exhaust devices

Installing the hood in the kitchen in a private house, the apartment involves several simple fixtures and connection to the existing ventilation.

But the process may differ - it all depends on what type of hood is selected.

At the place where the installation will be carried out, they are divided into wall, corner, built-in, island and fireplace:

• Wall-mounted and easy-to-install do-it-yourself wall-mounted ones are used most often. In this segment there are many design and construction options - from oblique to dome. By the way, the installation of wall hoods can be carried out both on a free wall and in a small cabinet;
• Corner models in an apartment or a private house are not used so often, and therefore they always look interesting and attractive. In this segment, domed and T-shaped models are suitable for do-it-yourself installation;
• To create a concise and compact interior, installation of an integrated hood will be required. Partially recessed from fully recessed differs in the number of "visible" parts - in the latter case, only the suction surface remains visible;
• Do-it-yourself island models are mounted when it comes to the special layout of the kitchen, with working areataken out to the center of the room or by the window. This installation method is more common in a private house. Keep in mind that the number of designs of island models is limited, and their price is high;
• Fireplace hoods are considered the most powerful and can work effectively in large areas and high ceilings.

Exhaust devices are also classified by:

• The width of the exhaust zone is its standard values \u200b\u200bof 500, 600, 900 and 1200 mm. The width of the hood and the width of the hob must be consistent;
• Productivity - Sanitary regulations state that the air in the kitchen should change ten times per hour. Therefore, multiply the air volume of your kitchen by 10 and get the minimum hood performance. By the way, in an apartment and in a private house the same calculation rules apply;
• Installation height: the minimum parameter here is 700 mm. The higher the installation will be made, the more productive the device should be;
• The method of air purification. There are circulating ones (driving kitchen air through the filter and exhausting it back), flowing ones (using house ventilation to bring air outside the premises), combined;
• Type of installed filters. Coarse grease filters and fine filters for odor absorption are most relevant. The degree of complexity of the do-it-yourself installation does not depend on the type of filter, but different models of filters differ in the duration of operation. So, non-woven grease traps need frequent replacements, and metal ones will last a very long time, but they will need to be washed regularly. Replaceable are carbon filters that capture odors;
• Type of management. The most expensive hoods are electronically controlled. They are equipped with many useful indicators and functions;
• Noise level - devices selected for installation in an apartment or a private house must comply with existing sanitary noise standards.

And do not forget that the installation of an exhaust device with your own hands should be carried out according to certain regulatory documents.

And these are not only the rules prescribed by the manufacturer of the equipment, but also the corresponding SNiP - SNiP 41-01-2003 “Heating, ventilation and air conditioning”.

Rules for choosing ducts for installing the hood

To take the exhaust air from the kitchen to the ventilation in the house, air ducts are needed.

The air duct is used only for flow structures, but is not provided for recirculation ones.

The most popular types of air ducts that ensure the correct installation of exhaust hoods with their own hands (built-in, inclined, and other designs) are:

• plastic, made of durable polyvinyl chloride. They are characterized by compactness, durability, noiselessness and lightness. They are performed with a smooth surface, which practically does not create air resistance. Narrow rigid ducts or elastic pipes can be made of PVC - this allows you to install a hood with your own hands in the house so that the gap between the equipment and the ventilation hole does not attract attention;
• aluminum, in the form of a corrugated pipe. Him self-assembly   does not cause difficulties, since the pipe is easily bent to the desired size. Among the advantages of aluminum corrugation are the absence of vibration and hum, which distinguishes this design from a rigid box. However, you can’t name such an aesthetic duct in any way, you have to figure out how to hide it so that it does not spoil the interior of the kitchen. This method is good if we are talking about a built-in range hood or if the room has a drywall ceiling.

Work progress when installing a cooker hood

Installation to make ventilation in the house is carried out according to the following algorithm:

• For the electrical connection of the hood with a tap, a separate outlet is required;
• On the wall, in the place of the alleged fastening, preliminary marking is performed. For these purposes, it is better to use the template that comes with the equipment. But if such a template was not provided in the delivery package, then the markup is performed independently, using a tape measure and a pencil;
• If we are talking about installing a suspended hood with a tap, it is mounted only after the kitchen set is fully assembled and all upper cabinets   fixed;
• To install the device you will need dowels and screws. A correctly selected duct of the appropriate length will ensure the connection of the device to the common house ventilation shaft;
• It is important to choose not only the length, but also the diameter of the duct, as well as the method of its location;
• Excessively long air exhaust or the presence of more than three bends in it will reduce the performance of the hood. It is also forbidden to narrow the ventilation duct. It is preferable to use plastic round boxes with a diameter of more than 12 cm, rather than corrugated metal pipes, because they are less noisy
• During the installation process, it is important to ensure that the hood is installed horizontally;
• To connect the hood to the existing ventilation shaft, an additional plastic box is laid. In this case, the cross-section of the duct must correspond to the diameter of the existing outlet;
• After installing the air duct, install the casing for ventilation and adjust its height;
• It is necessary to connect the device to the mains and carry out a test run - if no malfunctions occur, the installation is completed.

Features of mounting a built-in model

Do-it-yourself installation of a built-in cooker hood provides for the preliminary assembly of the furniture frame, where the device will then be placed.

Note that in the part where the hood will be located, the bottom is removed, and therefore vertical fastenings in the cabinet will be required only in the upper part.

Before assembling the frame, mark the place of exit, then a hole is drilled in the upper partition for the outlet of the duct.

Most often, the ventilation duct or corrugation is carried out precisely through the top, but it can also be led out through the back wall.

The bottom of the cabinet is also marked for installation. The dimensions of the hood body are “translated” to the removed bottom panel.

In addition, cutouts for corrugation are noted. After the case is fixed on the panel, the corrugation is fastened - first, the adapter ring is inserted, and then the box is laid.

Connection with the existing ventilation system through the corrugation is carried out after fixing the hood in the cabinet.

The appliance’s electrical connection wire is also hidden in the cabinet - you cannot hide it directly under the stove in order to avoid overheating.

So it’s best to place the outlet behind the back of the cabinet.

And do not forget that a productive powerful hood requires an appropriate power outlet and cable in order to avoid overloads in the system.

A properly installed hood in the kitchen will help to get rid of such unpleasant phenomena as wallpaper and ceiling yellowed from combustion products, unpleasant odors during cooking, fogged up from steam windows, and continue to prevent their appearance.

Kitchen area and hood power

Installing a kitchen hood with your own hands is possible for any man, provided that the selection rules, installation and fastening of the device are carefully studied beforehand. It is also important to consider the size of the kitchen equipment - the width of the hood cannot be less than the surface of the stove.

The power of the device is an important factor. In this case, the rules dictate the size of the kitchen itself:

• to cope with the task of cleaning the air from smoke and odors in a small kitchen will help a flat hood with a small capacity;
• for an apartment like Khrushchev in order to save space good decision   installation of a medium-power hood will be installed, the duct of which is built into the cabinet;
• it is advisable to mount a fireplace hood, also known as a dome hood, in a large area kitchen - such an assembly is the most powerful.

Calculation of the height of the hood over the stove

The height at which the hood should be attached to the wall is determined by two important points:

1. It should be sufficient so that the structural elements do not melt from high temperatures.
2. When choosing the upper threshold for height, consider your height so that it is convenient to work with it.

As a rule, the instructions for the device indicate the distance at which the hood should be mounted from the stove. On average, it is 65-90 cm.

When using a gas stove, the height threshold is higher (about 75-90 cm) than for an electric one, which requires 65-70 cm.

Installing the hood in the cabinet

Installation of the built-in hood is carried out in ordinary kitchen Cabinet. If you have certain skills, you can mount the exhaust panel on a telescopic retractable mechanism. In this case, when the device is not used, it is easy to hide from prying eyes.

It’s faster and easier to install a static model in a cabinet that hangs on the wall above the stove. For work you will need:

• jigsaw or hacksaw,
• bolts
• euroscrews
• screwdriver,
• tape measure and pencil.

We carry out the installation of the hood:

1. The cabinet in which the hood will be built in will have to be redone for the installation of the hood: first of all, the bottom and the furniture cover are removed.
2. Using a jigsaw or a hacksaw, a hole for the duct is cut out in the cabinet lid.
3. In the cabinet, on the surface of its bottom, a pencil transfers the hole pattern for fastening bolts, corrugations and cable.
4. The cabinet is mounted to the required height.
5. Attach the hood housing to the cabinet at the side walls with Euroscrews.
6. An air duct is drawn through the lid and hermetically connected to the structure.
7. The cable is pulled to the outlet.

How to install a corrugation on a hood

The technology of installing the corrugation on the hood has a number of its subtleties:

• the choice of the diameter of the corrugation depends on the size of the exhaust outlet;
• before installing the corrugation, you should stretch it as much as possible - this technique will significantly reduce the noise level during the operation of the hood;
• the corrugation with a clamp is fixed on the exhaust pipe, and special grilles are used for fastening on the ventilation hole;
• all joints and joints should be sealed.

Mounting a fireplace hood

Fireplace or dome hoods are the most common choice for the kitchen. Installation of the fireplace hood is carried out on the wall, since the kitchen cabinet for this purpose will not work because of the significant size of the device. However, due to the wide variety of shapes and sizes, this type can be easily fit into any interior without harming the overall design.

For work you will need:

• roulette;
• building level;
• pencil;
• drill;
• drill;
• screwdriver;
• dowels;
• wood screws.

Proceed to install the hood:

1. First of all, it is necessary to mark on the wall where and how the device will be mounted. Above the stove, according to the instructions, use a level to draw a horizontal line at the required height.
2. Measure the total height of the device. If the pipe rests on the ceiling, the excess is cut off, since the hood should not fall below the mark drawn.
3. An axis is marked on a horizontal line and a vertical line is drawn using a level. Measure the distance from the bottom of the case to the last pairs of mounts and mark it from the horizontal up parallel to the center line.
4. Holes are drilled in the wall, dowels are inserted into them under the screws. Attaching the hood is recommended to start from the top of the housing. The device is aligned horizontally, after which the entire body is fixed.
5. The exhaust outlet is connected to the ventilation system using a corrugation or a plastic duct. The closer the hood is installed to the ventilation, the less curved and shorter the air duct, which means that the output of the suction soiled device will be better.

It is advisable to provide a check valve device. This will prevent air from entering the room with harmful fumes and carbon monoxide from the ventilation duct.

Duct installation

When the ventilation hole is located near the stove, installing a hood in the kitchen with your own hands is not particularly difficult. Otherwise, there is a need to mount the duct. It is made from various materials, and each of them has its own characteristics:

• steel is the most durable, but this material is more difficult to work with during installation;
• aluminum is light and mobile, it is easy to give it any shape;
• plastic is convenient in work; it is easy to make airtight seams on structures made of this material.

The shapes of the ducts are round and rectangular. Round models are more productive, and the design with right angles is easier to fit into the interior of the kitchen.

Corrugated duct made of aluminum. This allows you to stretch and compress the product, bend at the desired angle. Before mounting, experts recommend stretching such an air duct to the maximum, and cutting off the excess pipe. Thus, the performance of the system is increased, since the folds will not create resistance to the air masses passing through it.

The advantage of the duct made of steel and plastic is that they are easy to hide from prying eyes behind hinged cabinets. Rectangular structures are made of sectional parts that simply assemble the required length.

During installation, it is important to consider the following points:

• every bend reduces system performance by at least 10%, so try to keep them as small as possible;
• operational efficiency also depends on the length of the structure; it is undesirable for it to exceed 3 m;
• to avoid additional noise, check valves should be installed vertically;
• the diameter of the exhaust opening must correspond to the pipe or be slightly smaller, otherwise the load on the system will increase and productivity will be reduced;
• the corrugated pipe is mounted using clamps, for a rectangular duct, it will be required for an adapter: one for mounting on the ventilation hole, the other on the exhaust device.

How to install a hood in the kitchen (video)

Installation of the hood will require some effort and material costs. However, it’s worth it, because such a device will not only protect the kitchen from frequent repairs, but also significantly improve the quality of life and preserve the health of your family members. The hood can be installed in a cabinet, as hidden or leave it open. Further care of the device consists in cleaning and, if necessary, replacing the duct with a new one.

Attention, only TODAY!

The question of how to mount the hood in the kitchen, today worries many. When making repairs in the kitchen, in most cases people think about how to create a ventilation system more efficient, because it is not just convenient, but even necessary.

A person who cooks regularly spends about five hours a day in the kitchen and breathes in harmful fumes, including chad and cinder.

In addition, during cooking, tiny particles and fats are released into the air from food, which also adversely affects human health.

The only way out in this situation is to buy and install the hood, since neither traditional ventilation systems nor simple ventilation will provide the desired effect. About how to properly install the hood in the kitchen and will be discussed in this article.

Hood selection

One of the most important systems in a person’s home, ensuring the comfort of his life, is ventilation. In a sufficiently ventilated room, the air is clean and fresh, which is why it is simply pleasant to be here, while stuffiness can cause negative reactions of the body, up to general weakness and dizziness.

Cooker hoods are one of the main ventilation components, since cooking is associated with increased air temperature and harmful emissions, including also very unpleasant odors.

The main objective of the hood is to clean the air in the room. And the cleaning process itself can occur in different ways. The fastening of the hood for the kitchen directly depends on this. So, there are two types of work of modern range hoods.

Types of hoods

1. The simplest exhaust device works on the principle of air recirculation. At the same time, air is not removed outside the premises, but passes through special filters and returns. Sometimes such hoods are also called filter hoods or suspension hoods (see also the article about).

Hoods of various types. Bottom - filtering.

Naturally, you do not need to connect such a hood to the ventilation shaft. The only installation item provides for wall mounting.

The advantages of such mechanisms are their price, stylish design, low noise and ease of installation. The disadvantages of this type of hoods include a relatively low efficiency, because during recycling it is not enough to completely clean the room.

1. The second type of hoods include all those that take air out of the room. In this case, it is necessary to withdraw the kitchen hood to the street or to a specially provided ventilation shaft (see also article about).

Such devices are mounted on the wall or directly on the ceiling above the stove. Ventilation pipes can be masked with the help of hanging cabinets, which allows you to partially or even completely hide their presence.

Such hoods require more serious installation work, but the instruction is not too complicated.

What to look for when buying a hood

If you have chosen the second type of device, then you need to consider the following factors when purchasing it:

1. The size of the valve and corrugation should match the size of the ventilation hole located in your kitchen.
2. Engine power is checked as follows. If you bring a sheet of paper to the included hood, it should stick to the curtains.
3. The dimensions of the hood should not be less than the surface of the plate, and preferably a little more.
4. Noise level must not exceed the permissible 40 decibels.
5. Also take into account the energy consumption of the hood.

How to fix a kitchen hood - a photo of properly installed equipment.

Mounting the hood

Before connecting the hood in the kitchen, you must make sure of the following:

• The corrugation should be as stretched as possible, because the folds will create vibrations and reduce the system.
• As a result of installation, the corrugation should have a minimum of bends. Each 90 degree bend reduces system efficiency by 10%.
• The distance between the cooker hood must be at least 70 cm.

You can read more about how high to hang the hood in the kitchen in the manufacturer's instructions. By default, it is customary to place it at a distance of 70-80 cm from the surface of the plate.

The decision on what height to hang the hood in the kitchen also depends on the ratio of the size of the stove to the hood itself, since its surface should absorb all the steam and fumes.

Advice! If the ventilation shaft is clean and perfectly pulls, then you can remove the valve from the hood and allow it to work with the engine turned off. This is possible in homes with adjustable ventilation.

Ventilation hood connection

Since it is not difficult to mount the hood in the kitchen, you can deal with this procedure yourself. But it’s better to take an assistant.

1. We apply the hood to the wall and use a pencil to mark its future position. If you plan to change kitchen furniture, you should consider embedding the hood in a hanging cabinet.
2. We drill a wall punch under the dowel. It is not worth it to hack, because the design must be fixed “tightly”.

1. We fasten the hood to the wall.

1. Next, you should fully prepare the ventilation outlet by cleaning it from construction waste.

1. We put the corrugation on the valve and fix it with silicone sealant. The free end of the pipe should be run as deep as possible into the shaft. If other repair work in the kitchen is not planned, then the corrugation can be foamed with mounting foam.

1. The final step is to put on a pad that hides the corrugation. If it is attached to the wall, then you will have to drill a couple more holes.

On average, installation time takes 1 - 1.5 hours.

Hood Service

• Regardless of how expensive and high-quality hoods you buy, in the process of its operation some very unpleasant nuances may occur associated with breakdowns or a decrease in the efficiency of the ventilation system. Therefore, along with the question "how to put the hood in the kitchen" there is also the question of proper maintenance.
• If you not only correctly install the hood, but also provide it with the necessary care, this will significantly extend the smooth operation of this appliance. The first rule in the care of ventilation mechanisms is the timely replacement of filter elements.
• This is especially true for suspended hoods, which are filter hoods. In this case, the filter is the only weapon of the device against polluted air, and therefore it needs to be changed regularly. In most cases, disposable acrylic grease traps are installed on the cheapest hoods, due to which the air is cleaned of grease and food particles.

• The same filters are in hoods designed to remove air from the room through the ventilation shaft. However, we can talk about reusable grease traps, which are washed and installed in place.
• Changing the grease filter in a timely manner can protect you from fire. It's no secret that fat burns well. A large accumulation of grease on the filter can cause the surface of the hood to catch fire. Therefore, timely filter change is important in terms of safety.
• Before extracting in the kitchen, stock up on a few grease filters to prevent premature equipment breakdowns.
• Carbon filters are also installed in the suspended hoods, which are directly responsible for air filtration. They can be collapsible (in this case, you can replace the coal base) and collapsible (the filter simply changes to a new one).
• When buying carbon filters, you should beware of fakes. In this case, we can draw an analogy with printing equipment. So, there are both new cartridges for the printer, and those that were “refilled”. Naturally, the latter option is cheaper, but the print quality in this case is noticeably lower.
• The same situation is in the market of carbon filters. Here the so-called “regeneration of coal powder” is actively carried out. Therefore, you should not buy too cheap a carbon filter, since it is highly likely that it is regenerated, which indicates the reuse of coal powder.

Extraneous odors, excess moisture, formed during cooking on the stove, are removed from the room.

Therefore, the installation of the hood in the kitchen is an important point on which the level of comfort in the kitchen room depends. Depending on the type of cooker hood, the installation methods may vary.

Of course, you can invite a specialist to do the work if the price of installing the hood in the kitchen suits you. In the case of installation in a ready-made ventilation system, the cost of work will be about $ 25-35.

If you have to bring the device outside the house, then the cost of installing a kitchen hood will increase by about half.

All hoods by type of placement are divided into the following categories:

• Recessed. Installation of the built-in hood is carried out in a wall cabinet.
• Wall. They are mounted above the stove on the wall. Design can be anything. In this case, it is always installed.
• Corner Located in the corner of the kitchen. Attached mainly to the walls.
• Island. Designed to be placed above the stoves located in some place in the middle of the room.

The installation cost of the hood directly depends on the complexity of the installation.

2 Island hood mount

An exhaust device for a freestanding cooker is mounted by suspension. Since the hood has a certain weight, it must be fixed to a solid ceiling surface.

If you have installed a suspended or suspended ceiling, then the fasteners must pass through these coatings. This implies an appropriate length of fixtures. Ideally, an extractor hood is installed first, a ventilation duct is laid, electricity is supplied, and then the ceiling is mounted.

But you can mount the hood on the finished ceiling. True, in some cases, for example, on stretch ceiling, it is advisable to entrust the work to specialists. This will prevent damage to the ceiling. The cost of installing hoods in the kitchen by specialists will depend on the complexity of the work and its features.

For island hoods, the amount will be around 5000 rubles, while for ordinary wall and small domed hoods, the price ranges from 1000 to 2000 rubles. depending on installation features.

2.1 Mounting the hood to the wall

It does not matter whether the installation of an inclined hood in the kitchen or a hood with a horizontal surface, the principle of its attachment will be the same. Usually there are mounting holes on the back of the device.

It is best to attach the hood to the wall on long dowels by using a punch. Mounting on anchors is undesirable, since then it will be impossible to remove the hood.

2.2 Duct connection

The air duct can be made in two versions: a plastic box and a corrugated aluminum pipe. The first one looks better, and the second is more convenient and simple to install.

When installing built-in kitchen hoods, fixing the duct is complicated by the presence of a cabinet.

To connect the duct, you need to make a hole in the upper part of the cabinet, and then pass the pipe there. The installation of built-in kitchen hoods has one drawback - the duct takes up free space in the cabinet.

Connecting the duct to a wall or island hood is very simple. Using a clamp, the exhaust duct is attached to the hole in the exhaust hood. It is recommended to apply a layer of silicone at the junction of the channel to provide better traction.

2.3 Removing air ducts to ventilation

The connection of a kitchen hood to ventilation can be carried out in two versions:

• The duct is discharged into the house ventilation duct. It is better to fix it to a special grille with a clamp. This grille is good in that in addition to the hole for the duct, it has several holes for free ventilation of the room. Thus, when the hood does not work, the room is ventilated in a passive mode.
•   displayed on the street. If the ventilation duct of your house has a low bandwidth, then it will not be able to properly extract air. Air jams may occur. In this case, a hole is made in the outer wall of the house, into which the air duct is drawn through the check valve.

2.4 Connecting the hood to the power supply

The installation of the hood in the kitchen ends with its connection to the mains. The exhaust device operates in conditions of high humidity, therefore, the risk of short circuit to the device body is increased.

To ensure the safety of people and to prevent fire, it is recommended to connect an exhaust fan through a ground wire and a circuit breaker.

If the sockets in the house are equipped with a grounding wire, then no additional steps need to be performed. If the usual two-wire wiring is carried out, then an additional grounding wire must be laid.

It is carried out from the electrical panel, heading through the circuit breaker to the outlet into which the hood is connected. The wire is hidden in the cable channel to ensure aesthetics.

If a dishwasher is installed in your kitchen, then it should also be connected to this outlet. To do this, you can install a twin outlet.

2.5 Installing an exhaust device in the bathroom

In addition to the kitchen, it can be installed in the bathroom. But, unlike the kitchen, an exhaust fan is installed in the bathroom. This is quite enough to remove excess moisture.

Installation of the hood in the bathroom is made in the ventilation hole. For this, any fan with sufficient power is suitable. The market is replete with devices that have special spacers for ventilation ducts.

Installation of the hood in the bathroom is carried out in the following order:

• Before installation, the fan is fixed in the ventilation duct.
• Power is provided through a cord that runs on top. false ceiling   or goes down from the fan.
• Installing an exhaust fan in the bathroom is completed by attaching a decorative grill to it.

2.6 Hood for gas boiler

As a rule, gas boilers are installed in private homes, so the installation of the exhaust gas boiler is reduced to the removal of the duct into the street. Best option   this will be the installation. For such devices, two types of ventilation are provided: natural and forced.

If the boiler is low-power, then a conventional chimney that removes combustion products naturally can be enough.

In the case of using a powerful unit, the installation of a hood for a gas boiler includes the removal of vertical and horizontal ducts with an exhaust fan outside the house.

A rare kitchen set without built-in appliances. The compact built-in range hood has become such a popular piece of furniture that almost every upper tier is equipped with it. Do-it-yourself hood installation is relatively simple if you act sequentially and follow our instructions.

Furniture design requirements

The very design of the cabinet under the built-in hood is quite trivial. It has two side walls with a total depth of the upper tier, fastened by an upper horizontal partition and without a bottom. There should also be an internal shelf located between the walls. It is better not to order an additive for this part during manufacture: four confirmations can also be drilled manually in place, but then the hood will be installed as tightly as possible. You can add a few more details to equip the internal space of the cabinet, we will talk about them later.

The situation with dimensions is more complicated. In order for the appliance to fit harmoniously after installation without creating significant gaps and gaps, the hood or its drawing with the main overall dimensions should be on hand at the time of furniture production. The size of the hood is selected in accordance with the width of the stove or hob, in fact the case is a couple of centimeters larger.

The widest lower part defines the main dimensions of the cabinet. The outer size of the cabinet must exactly match the width of the hood. The depth of the furniture case may be 50-60 mm more, in this case the hood is shifted to the front edge, and the open area at the back is closed by a thin fastening partition. Please note that the housing of the hidden exhaust unit has a gap of 10-15 mm from the cabinet walls - this is one of the most important conditions for installing built-in electrical appliances.

With the height of the cabinet is still less clear. In general, the distance between the tabletop and the bottom of the upper tier is from 50 to 65 cm, while the recommended distance between the hood and the stove is 75-80 cm for gas and 60-65 cm for electric hobs. It turns out that the section with the hood usually falls out of the general row, the cabinet height can be 80-120 mm less than the others.

Extractor hood

Depending on the type of housing, there are two ways to secure the hood. The first and simplest case is the vertical orientation of the technical unit. The hood in this case is attached to the wall, and the cabinet plays a purely decorative function, hiding the installation and all its technical details.

When installing the vertical unit, you only need to pre-hang the case without doors, attach a hood from the bottom and outline the mounting holes. After that, in the shelf you need to make a jigsaw cutout for the exhaust duct, which is usually located close to the wall.

Hoods with a horizontal arrangement of the technical unit are mounted according to a slightly more complex scheme. It is good if a card or a marking template for fixing holes is attached to the instructions. Otherwise, you will first have to measure the upper wall of the hood housing, starting from the edges and taking into account the gaps between the hood and the cabinet walls. The task is simple: outline 4-6 holes for the mounting screws and mark the center of the hole for the exhaust duct. He, which is typical for horizontal hoods, is not located close to the wall, so the hole is not cut from the edge.

The easiest way to tightly fasten the hood is to first screw the shelf to it, then turn the cabinet over and insert the resulting assembly from above. It remains only to mark and drill holes, and then pull the shelf to the walls with confirmations.

Rarely, but it still happens that the hood does not have regular mounting holes. In this case, its body is fixed with ordinary self-tapping screws with a frequent thread pitch (as for GCR). It is only necessary to make sure that the tip does not damage anything from the internal equipment.

When the hood is in recirculation mode, no additional steps are required. Exhaust air is directed inside the cabinet, which has enough natural clearances. In extreme cases, the duct runs along the entire height of the cabinet and ends immediately behind its upper wall with a simple strainer.

However, if the exhaust air is planned to be discharged into an external ventilation duct, installation of an air duct will be required.

The first thing that comes to mind is an aluminum corrugated pipe. It is quite convenient to use: it is easily deformed, it needs to be joined in only two places: on the flanges of the hood and ventilation duct it is simply crimped with screw clamps.

A closer look reveals a number of flaws in the corrugation. The internal ribbed walls create high aerodynamic drag, as a result, the real hood power may be lower than expected. Grease inevitably accumulates on internal surfaces, dust adheres, and with intensive air movement the corrugation makes a lot more noise than other types of channels.

Plastic ventilation ducts have a more noble appearance, are less prone to clogging and look much more harmonious when laying on cabinet furniture. Sometimes a corrugation is given a rectangular cross section for greater compactness, but this, as you know, is not the most technologically advanced approach.

The main disadvantages of rigid plastic ducts are slightly higher cost than corrugations, as well as the obvious complexity of installation. But there is another side: such a channel can be drawn directly inside the cabinets of the upper tier, after making through holes. You can also lay a canal along the "roof" of the upper tier: it will be pressed tightly to the cabinets and will not be visible from a height of human growth.

We mentioned additional cabinet details for a built-in range hood. The lower part, where the technical unit is located, can be closed with a blank partition. Another solution is also widespread: this part is closed by a small cut-out of the facade material, which is fixed permanently, and above, where there is still some free space in the cabinet, there is a door of any convenient type. Inside the cabinet, you can also collect a small case in which the exhaust channel will be placed, and the remaining space divided by a pair of shelves.

No one denies the difficulty of installing a rigid duct: both precise trimming and the correct selection of adapters and connections are needed. But the result is definitely worth it: the channel will be compact, neat and in no way limit the functionality of the hood.

Electrical connection

The built-in range hood has a side or rear terminal for the power cord. It is enough to plug the cord into a power outlet and you can immediately use the equipment. Hoods with built-in lighting may require pre-installation of lamps. It is better to do this after the installation is completed, so as not to damage the lighting devices through negligence.

Difficulties begin when there is no power outlet in the immediate vicinity for connection. In this case, the most convenient way to apply power is to increase the wire. The cores must be twisted, soldered and insulated with a heat shrink tube. Often the most convenient route for laying is the ventilation duct itself.

The wire must be pulled into the hood housing and then laid inside the chimney. To withdraw the cable from the duct, a hole with a diameter of a millimeter less than the thickness of the conductor is sufficient so that the passage does not have to be additionally sealed.

Option to address the issue of lack of power

Most low-cost built-in hoods are compact, but this advantage is at the expense of the power of the air pump. This can be eliminated by a simple revision.

It is about installing an additional duct fan anywhere in the exhaust duct. This will require only a couple of adapters and the laying of the fan power cord in parallel with the channel or inside it.

Installation can be made in order to increase power, that is, taking into account the parallel operation of a regular air pump and an additional duct fan. It is also possible to completely replace the built-in fan with an external one with access to a power of 1500-2000 m 3 / h against a standard capacity of 800-1000 m 3 / h - these are the characteristics that are typical for most inexpensive equipment.

It is worth remembering that the switch of multi-mode hoods may not be designed for parallel connection of an additional fan. If you can’t figure out the scheme, it’s better to install an additional housing switch, since you only need to drill one additional hole in any convenient place.
