The minimum distance from the hood to the electric stove. The installation height of the hood above the gas stove - choose the optimal distance

The ventilation ducts that are located in the building do not always cope with the problem of exhaust air. Often, they are ineffective. The way out of the situation could be exhaust system.

Starting installation, the question arises, what should be the distance from the stove to the hood and what kind of hood should I hang in my kitchen? This question is very relevant. The quality of its work and the degree of air purification depend on the height at which the kitchen hood is installed.

The design is designed to remove dirty air, fumes, soot, odors, gas combustion residues and other harmful components outside the building or clean the air with its subsequent return to the kitchen. The level of cleansing the room from dirty air depends on the height at which the hood is hung and how the air will be cleaned.

Depending on where the intake air goes, the method of cleaning it is determined. It can be flow or circulating. Which exhaust system to pay attention to depends on the conditions of the kitchen equipment and the presence of ventilation shafts in the building.

The flow-through cleaning method consists in drawing in dirty air and removing it through the ventilation system of the building outside it. positive side of this method is the maximum and fast cleaning kitchens from harmful air. To receive fresh air enough to open a window or window.

The circulation method is based on the suction and pumping of dirty air through a system of carbon filters, with its subsequent withdrawal into the kitchen. This method does not require equipment. ventilation ducts. A significant disadvantage is long time air purification and rapid wear of filters.

Varieties of exhaust devices

Depending on the location of the stove, the design of the kitchen hood and the method of its installation are selected. Exhaust systems for the kitchen are divided into the following types:

1. Suspended. They have a flat shape. The place of installation can be the bottom of a wall cabinet or shelf.
2. Embedded. This type is mounted instead of the bottom of the wall cabinet. Often the cabinet itself serves as a housing that hides the exhaust system and its communications.
3. Wall. Installation is carried out above the stove, like a suspended exhaust system. But the mounting of the system case is carried out on the wall.
4. Corner. Installation of such devices is carried out above the stoves, which are located in the corner of the kitchen. They have an angular shape.
5. Island. Used in bulk kitchen areas. Mounted on the ceiling in the center of the kitchen.

If your favorite pastime is cooking, then you should consider the right equipment for kitchen. After all, all the smells that come from fragrant dishes will absorb curtains, wallpaper and kitchen furniture, and over time your kitchen will acquire a very specific smell.

During frying, especially meat, small particles of fat rise up and settle on working surface, and also give an unpleasant aroma to the room. In this regard, the purchase of an air purifier is one of the major events when equipping a kitchen, this equipment should be installed as close to the stove as possible.

Having purchased this equipment, the installer may have a number of questions. The main one - at what height? After all, how well and how long it will last depends not only on the correct choice, but also on how correctly it was installed. To determine the height of the hood mounting, you must first decide what you want to install.

Filter hoods

by the most simple device is an extractor hood that simply recirculates air. When installing such a hood, the air is simply filtered through specially designed filters and not vented outside. These types of hoods are called suspended or filter hoods. This type of device does not need to be connected to a ventilation shaft. Such hoods have a number of advantages, they are almost silent, they have a very stylish and interesting design, they are easy to install and such hoods have quite acceptable price. The disadvantage is that air recirculation will not always completely eliminate odors in the kitchen.

The next step is to drill the walls under the dowels. This process should be done with high quality, since the hood must be attached very well. Having screwed the hood, puts the corrugation on the valve and securely fasten it with silicone sealant. On average, the installation of the hood will take you about 1-1.5 hours.

The question of how to mount the hood in the kitchen is of concern to many today. Making repairs in the kitchen, people in most cases think about how to create a more efficient ventilation system, 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 harmful fumes, including fumes and fumes.

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

The only way out in this situation is to buy and install the hood, since neither traditional systems ventilation, nor simple ventilation will not provide the desired effect. About how to properly put the hood in the kitchen and will be discussed in this article.

Hood selection

One of the most important systems in the dwelling of a person, providing 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 units, since cooking is associated with increased air temperature and harmful emissions, including very unpleasant odors.

The main task of the hood is to purify 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 hoods.

Types of hoods

1. The simplest exhaust device works on the principle of air recirculation. In this case, the air is not removed outside the room, but passes through special filters and returns back. Sometimes such hoods are also called filtering or hanging hoods (see also the article about).

Naturally, it is not necessary to connect such an extract to the ventilation shaft. The only item in the installation provides for mounting on the wall.

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

1. The second type of hoods includes all those that remove air outside the room. In this case, it is necessary to bring 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 using wall cabinets, which allows you to partially or even completely hide their presence.

Such hoods need more serious installation work, but the instructions are not overly complicated.

What to look for when buying a range 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 corrugations should match the size of the vent 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 must not be less surface plates, and preferably a little more.
4. The noise level must not exceed the permissible 40 decibels.
5. Consider also the power consumption of the hood.

Hood installation

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

• The corrugation should be as stretched as possible, since the folds will create vibrations and reduce the operation of 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.

For more information on how high to hang the hood in the kitchen, you can read 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 at what height to hang the hood in the kitchen also depends on the ratio of the size of the stove and the hood itself, since its surface must absorb all the steam and fumes.

Advice! If the ventilation shaft is clean and "draws" well, then the valve can be removed from the hood and allowed to work with the engine turned off. This is possible in houses with controlled ventilation.

Connecting the hood to the ventilation

Since it is not difficult to fix the hood in the kitchen, you can cope with this procedure yourself. But it is better to take an assistant.

1. We attach the hood to the wall and mark its future position with a pencil. If you are planning to change kitchen furniture, then you should consider embedding the hood in a hanging cabinet.
2. We drill with a perforator the walls under the dowel. You should not skimp here, since the structure must be fixed "tightly".

1. We fasten the hood to the wall.

1. The next step is to prepare ventilation outlet clearing it of debris.

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

1. The last step is to put on an overlay 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 maintenance

• Regardless of how expensive and high-quality the hood you buy, some very unpleasant nuances associated with breakdowns or reduced efficiency can occur during its operation. 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 install the hood correctly, but also provide it with necessary care, it will significantly prolong smooth operation this appliance. The first rule in the care of ventilation mechanisms is the timely replacement of filter elements.
• In particular, this applies to suspended hoods, which are filtering. In this case, the filter is the only weapon of the device against polluted air, and therefore it must be changed regularly. In most cases, disposable acrylic grease traps are installed on the cheapest hoods, thanks to which the air is cleaned of grease and food particles.

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

Conclusion

Since the hood is attached in the kitchen using simple "folk" methods, you do not have to invite a team of specialists to perform the installation. Anyone who knows how to hold a drill and a screwdriver in their hands can easily cope with this task.

You can see how to properly hang the hood in the kitchen in the video material located at the bottom of the page. Also on our site contains detailed instructions for choosing and recommendations for the proper maintenance of hoods of any type.

To keep the apartment or house fresh and fresh air, the kitchen must be very well ventilated. Natural ventilation cannot cope with the task of timely removal of odors during cooking, therefore a special device is hung over the stove forced ventilation- kitchen hood. How to install the hood correctly, how to fix it and bring it into the ventilation system - more on that later.

Installing a hood in the kitchen is a wise decision

How to hang a hood over the stove

With the right size, it is equal in width to or even slightly larger than the width of the plate. To properly install the hood, it must be correctly positioned and secured. The electric hood is located exactly above the stove. Installation height depends on the type hob:

• Above gas stove minimum allowable height hanging hood - 75 cm.
• Above the electrical value is slightly less - 65 cm minimum.

You determine the exact height yourself - according to the height of the hostess who will cook. The bottom edge of the hood should be just above her head. Less than minimum distance you shouldn't hang it, but you can go higher. But if you need to hang the equipment higher than 90 cm from the level of the stove, you need a unit with increased power— to remove polluted air efficiently.

The hood is attached depending on the type. Built-in - to a cabinet specially ordered in size. Hinged (flat) and domed (chimney) - to the wall. Chimney hoods themselves can consist of two parts - a unit with a motor and filters and a dome. Both parts are attached independently of each other, but so that their outputs coincide.

Separately, it should be said about island hoods. They are attached to the ceiling. The kit comes with a suspension system and clear recommendations on what and how to do.

Installation steps

The entire installation and connection process can be divided into several stages:

If there is a power outlet nearby, there will be no problems with connecting to electricity. Other stages are also not very complicated, but we will consider them in more detail.

Mounting to the wall of a hinged or domed model

Although outwardly these two models differ, they are attached to the wall. On the back wall they have four holes in the body - two on the left, two on the right. Many manufacturers supply their products with a mounting template, which marks the location of the fasteners. All that is needed is to lean the template against the wall, transfer the marks. If there is no template, measure the distance between the holes, transfer to the wall. If there is an assistant, you can ask to hold it at the chosen height, and make marks yourself.

Then everything is simple: using a drill, we make holes right size, insert the plastic plugs of the dowels, then hang the hood on the dowel-nails. Naturally, we check the horizontalness of the installed equipment.

This method is good if the wall is even and nothing interferes. Often passes next to the stove gas pipe, which makes it impossible to hang the hood close to the wall. In this case, you can nail on the wall wooden blocks, and already attach the hood to the bars. This is a simple option, but not very good - the bars are covered with soot and it is difficult to wash them.

The second option to install the hood behind the pipes is to use a stud screw (the second name is a plumbing stud). They have a thread for screwing into the wall, a smooth part, which makes it possible to take the hood some distance from the wall, and a finer thread with two nuts, which will fix the body. Have these pins different sizes, choose which one you need, but all nuts are made for a bit or an octagonal key.

This option for mounting the hood is universal, simple in execution, and reliable. It is also more convenient to maintain - the metal is usually stainless, it is not difficult to wash it from deposits.

Installation of a built-in hood in a cabinet

The built-in hood is almost completely hidden in a cabinet made for it. It is fastened in the same way as described above - on screws, only they are screwed into the walls. Only previously in the shelves located above it is necessary to make holes for the air duct. This is done after the hood is purchased, since the location of the air outlet depends on the company and model.

If the locker is hanging, it is better to remove it. In the removed cabinet, install the hood in place, mark the location of the air outlet on the lower shelf, cut it out. To do this, it is easier to use an electric jigsaw and a file with fine teeth. The saw blade for laminate leaves almost no chips. If desired, the cut point can be sealed with a plastic C-shaped furniture profile. They are rigid and flexible. Flexible is easy to use - it bends at any angle, rigid ones will have to be warmed up before installation building hair dryer. These profiles are “sit down” on glue, most often they use “liquid nails”. After installation in place, remove the remaining glue (with a damp clean cloth), fix masking tape to the shelf. We cut off the excess profile with a file with a fine tooth, we clean the cut sandpaper with fine grain.

In the same way, we make holes in other shelves. By the way, they may no longer be round, but rectangular - it depends on the section of the air duct you have chosen.

After that, all the shelves are installed in place, the cabinet is hung and fixed. A built-in hood is attached to it with screws through the holes in the case. Next is the process of connecting the duct.

How to connect the hood to electricity

Since the power consumption kitchen hoods rarely exceeds 1 kW, they can be connected to ordinary sockets. It is desirable that they be grounded. This requirement must be met if you want to warranty obligations were valid.

If the wiring in the apartment is old, you can throw the ground or ground wire yourself. Just do not attach it to plumbing or heating pipes. This threatens the possibility of electrical injury or even death for you, members of your sichs or neighbors.

To reach the ground wire, on the shield, find a busbar with wires attached to it or a pipe to which a stranded wire is welded / screwed. You can also connect your own stranded wire to these devices (without discarding those that already exist). For it to work normally, the cross section must be 2.5 mm, the conductor is stranded copper, a non-combustible sheath is desirable.

Some of the hoods come with a plug at the end. With the connection of such models, there are no questions - to the outlet and that's it. But there are models in which the cord ends with wires. This is not from the greed of the manufacturer, but for the consumer to decide for himself how best to connect the equipment. If you want, you can connect the plug. This option is not suitable - take terminal block and connect through it. Another option is Wago terminal blocks. They need to take three pieces - according to the number of wires. In one terminal block, the same wires are connected from the hood and from the shield - phase to phase (here the colors can be different), zero (blue or blue) to zero, ground (yellow-green) to ground.

Air duct for kitchen hood

One of the stages of installing the hood is the selection and installation of air ducts. Air is vented from the kitchen room temperature, therefore there are no special requirements for air ducts and any can be used. Three types are commonly used:

There is another difference between plastic and corrugated duct - the price. Polymers are more expensive. Despite this, if you have the opportunity to install a hood with using PVC, put them on. With an equal cross section, they provide more efficient air removal, and also make less noise.

The cross section of the pipes for the duct is determined by the size of the outlet on the hood. In case of rectangular pipes use an adapter.

Dimensions of ducts for hoods

Round ducts are available in three sizes: 100 mm, 125 mm and 150 mm. This is the diameter plastic pipes and pleated sleeves. There are more sections of flat air ducts and they are presented in the table.

How to choose the size? In case of round pipes their diameter must match the diameter of the outlet of the hood. It is highly undesirable to put an adapter on the outlet, and then use a smaller diameter air duct - this will reduce the rate of air purification. And even if the hood is very powerful, then it will not cope with air purification.

With the choice of the section of a rectangular duct - the area of ​​​​its section should not be less area section of the outlet pipe. And the connection is made through a suitable adapter.

How to attach the corrugation to the hood and ventilation

If you decide to install a hood and use aluminum corrugation for the duct, you will need to think about how to attach it to the body and to the ventilation. To do this, you need clamps of the right size. They can be metal or plastic.

To connect the hood to the ventilation system, you will also need a special ventilation grill. It has a hole in the upper part for connecting the duct pipe. At the bottom there are holes for removing air from the kitchen with the help of natural circulation when the extractor is not working.

A grate with a ledge is suitable for fastening the corrugation - around the hole there is a side of a few centimeters, on which the corrugation is put on, after which it is fastened with a clamp of a suitable size.

By the same principle, a corrugated duct is attached to the hood. It has a ledge on which the corrugation is put on. The connection is tightened with a clamp.

How to fix the duct to the walls

For plastic air ducts there are special fasteners in the form of latches. They are first mounted on the wall using dowels. The installation step depends on the curvature of the track, but on average 1 mount per 50-60 cm is enough. Pipes are inserted into these latches during installation with little effort.

If the duct needs to be fixed to the ceiling, the same fixings can be used. But if you need to maintain a certain distance from the ceiling, this type of installation will not work. In such cases, they take perforated drywall hangers, attach them to the ceiling, then use small PVC screws for the exhaust duct to them.

Corrugated air ducts are attached to the walls with clamps or plastic puffs. big size. If necessary, they are also mounted to the ceiling using perforated aluminum hangers.

Where and how to bring the air duct

Most often, the duct from the hood in the kitchen is connected to air vent, through which there is natural ventilation (due to draft). This is wrong, since in this case most of the grille is closed by an air duct, and air exchange through the remaining available holes will be clearly insufficient.

Correctly connect the air duct to a separate ventilation duct. In this case, the same grate is installed on the hole as in the photo above.

If there is no separate ventilation duct, but it is located nearby outer wall, you can take the pipe outside by placing a grate outside. These are two ways to have normal ventilation and ensure the normal operation of the hood.

How to get outside

To install the hood and bring the duct into the wall, you need to make a hole in it. And this is the only difficulty. Further, an air duct is inserted into this hole, sealed with a solution. Outside, the hole is closed with a grate - so that debris does not get in, birds and small animals do not settle.

To prevent air from the street from blowing into the room, a check valve is installed (in the figure above it is indicated by an oblique line). By the way, it is also desirable to install it when connecting the air duct to the ventilation system - so that odors from the pipes do not enter the room.

Reverse or anti-return air valve represents light plastic or a metal plate. It is movably attached in two places to the pipe - at the top and bottom, the petals are supported by a slight spring. While the hood is not working, the valve blocks the access of air from outside. When the hood is turned on, the air flow bends the plate forward, squeezing the spring. As soon as the hood is turned off, the plate returns to its place with the help of springs. If you install a hood without this valve, it can be too cold in the kitchen in winter - outdoor air will get into the room without problems.

So that the hood does not interfere with natural ventilation in the kitchen

With a tee and check valve By the way, you can install the hood so that it does not interfere natural ventilation in the kitchen. You will need a special ventilation grill for connecting hoods, a check valve and a tee. A tee is attached to the ventilation grill, an air duct from the hood is connected to its lower inlet, and a check valve is placed on the free outlet, only so that the petals are locked when air passes from the pipe (in the photo below).

How does such a system work? When the hood is turned off, the check valve petals are bent, air from the kitchen enters the ventilation duct through the grill and open outlet tee. When the hood is turned on, the air flow from it unfolds the valve plate, and the air goes into the ventilation system. When the hood is turned off, the springs again open access to air through the tee.

Outwardly, such a system does not look very attractive and it will have to be somehow masked. But this is the only way to connect the hood to the only existing ventilation outlet and not reduce air exchange.

One of the criteria for choosing a hood for the kitchen is its size. They are different, but since they are standardized, then choose suitable model it will not be difficult, especially if a competent sales assistant helps you. And yet, it is better to know some rules and nuances before making a purchase.

Dome Width = Slab Width?

Width is the first thing you need to pay attention to when choosing the size of the hood, since it is it that significantly affects the efficiency of collecting grease particles, odors, and fumes. What size should the hood above the stove be, so that even when operating in a weak mode, which means with less energy consumption, wear and noise, it is still effective?

• Focus on the rule: the hood should be equal to the stove, and ideally wider. If the width of the hood is less than the hob, or it is located not above the stove, but slightly offset, then the quality of air purification will noticeably decrease;
• If you have not chosen a stove yet, then you need to focus on the distance between the wall cabinets or the dimensions of the wall module in which the built-in hood will be installed. If space allows, then choose a 60, 80 or 90 cm hood.

Kitchen hoods are available in the following sizes: 30 cm, 45 cm, 50 cm, 60 cm, 80 cm, 90 cm, 100 cm and 120 cm wide. It is logical that the size range of a plate or built-in hob about the same. The most popular dome widths are 60 and 90 cm, as in this size they are best suited for standard plate with four burners. And here overall hoods with an umbrella of 100 and 120 cm, you will need to look, since the demand for them is small, because these are more likely not kitchen, but professional models.

You need to focus on the size of the working exhaust surface, and not on the size of the hood umbrella. It often happens that the dome itself is wide, but the working exhaust surface is small. An example of such an extract is on the right.

The built-in model, in this case, will be more practical due to the retractable element, which increases the catching area.

And on following photos you can see what sizes the built-in hood is, on the left - a model with a width of 30 cm.

Depth of dome and built-in model

The depth of the hood is as important as its width, because, as already noted, what more area working surface, the more effective cleaning of the kitchen air. Standard parameters depths correspond to typical width options, these are: 30, 45, 50, 60, 80, 90, 100, 120 cm. The depth of the exhaust worktop must be equal to or greater than the depth of the stove or built-in hob. The dome can be more deep hinged modules, but not more than the depth of the countertop.

But the depth of the hood for embedding is adjustable, but its body, of course, must correspond to the depth wall cabinets kitchen as shown in the photo below.

What should be the height?

Hoods for the kitchen are different and height. Max Height dome model - 125 cm.

The photo below shows examples of devices different heights(scroll right).

The height of the device must be selected depending on the total height of the room and the height kitchen set. Safety regulations regulate the minimum distance between the exhaust surface and the stove. As a rule, this value is 65-75 cm. Reducing this value is fraught with ignition and damage to equipment due to constant high temperatures. A built-in or dome hood must be at a distance of more than 65 cm from electric stoves, and for gas stoves this value is 75 cm.

Mounting Features

The choice of installation location is directly affected design features the model you like. wall or ceiling structures are not hidden by cabinets and are installed exactly above the stove, while special masking boxes are often used for the air duct. But the embedding model will require the manufacture of appropriate furniture.

Please note that to install the hood, you will need pipes, a socket and an electrical cable, boxes, mounting hardware and fasteners. You can not do without an air duct - it can be corrugated pipes or smooth sleeve.

Corrugated pipes are distinguished by the fact that they can be bent at any angle.

Keep in mind that bending the duct over 90 degrees is unacceptable.

Do not forget that there are special boxes that allow you to hide the air duct, integrate communications into any kitchen design.

The diameter of the duct directly depends on how the outlet in the house is made, and the length of the pipe is determined depending on the remoteness of the device, on the opening in the wall or on the ventilation shaft.

If we are talking about installing a built-in hood, then everything must be done in accordance with the installation instructions. The main criteria for installing a built-in device are:

1. The drawer of the device is always left visible;
2. The outlet is always connected to the ventilation shaft.

If there is no possibility of such a connection or it is impossible to lay air outlet pipes, then you can install a recirculation model - among them there are also options designed for embedding.
