How to properly install a flow hood over a gas stove? Distance from the stove to the hood: norms, rules and recommendations Installation of a gas hood.

The need to install a special hood over the stove is explained by the desire of users to get rid of extraneous odors and other fumes generated in the kitchen during the cooking process. At the same time, it is possible to ensure the required efficiency of indoor air purification only if certain rules and recommendations are followed, determined by the relevant regulations and standards. In this article we will introduce you to existing species exhaust structures and consider the order of their installation using the example of one of the most common models.

Types of kitchen hoods

Currently on the domestic market household appliances There is a wide range of kitchen hoods, which according to their design are divided into the following types:

• suspended design, which is one of the most convenient to install and practical exhaust devices, suitable for most ordinary users. With all the listed advantages, such a hood, however, is characterized by insufficient productivity;
• an exhaust device built into the walls or ceiling that provides the required efficiency in removing odors and fumes from rooms of a large area;
• an exhaust device designed in the form of a dome, the effect of which extends not only to the stove, but also to the working surfaces of the countertop located near it;
• the so-called “island” hood, mounted in the center of the kitchen space and providing air exchange throughout its entire volume (including above gas stove).

Auxiliary elements (air ducts)

As air channels through which unpleasant odors and fumes are diverted to the ventilation shaft hatch, special air ducts are used, made in the form of:

• corrugated pipe;
• rigid metal box;
• polyvinyl chloride pipes with smooth walls.

The advantages of corrugated pipes include their flexibility and relatively low cost. The disadvantage of this budget option air duct is the need for constant care during operation. A metal box used as an air duct is more convenient to use, but will require significant expenses from the contractor. The most optimal application option is considered PVC pipes, which is not only easy to install, but also does not require special care. Unlike other air ducts, this pipe is installed strictly above the hood.

Requirements for installation of the hood

We will consider the procedure for installing a kitchen hood using the simplest example hanging system, the installation of which requires the following requirements:

• The dimensions of the intake hole must correspond to the size of the gas stove, which ensures maximum effective removal polluted air;
• The height of the hood above the surface of the slab should not be less than 50-60 cm (the optimal distance from heating elements about 75-80 cm), which provides comfortable conditions for work. If it is placed too low, the space for working with the stove will be limited, and the body of the device itself may overheat;
• The performance of the exhaust device must correspond to the volume of the room being served and ensure that the air in it is renewed at least 10 times a day. For calculation exact value of this indicator it is necessary to determine the main dimensions kitchen room, and then use the following formula: V= SxHx10x1.3, where S and H are the area and height of the serviced room, respectively, and 10 is the minimum air exchange rate (1.3 is the correction factor);
• in the case where your house does not have a separate ventilation shaft with access to the kitchen, it is recommended to use a flow-type exhaust device with variable capacity, operating on the principle of air mass recirculation.

Note! Connecting such hoods to an existing ventilation shaft may disrupt the operation of the entire exhaust system as a whole. In addition, it is not recommended to turn on flow devices at full power (in maximum performance) for a long time.

Installation procedure for the hood housing

Installing a hood over a gas stove involves phased implementation a whole range of work operations of the following nature:

• hang the exhaust hood housing directly above the stove;
• installation of exhaust air ducts, ensuring their reliable connection with the hood and the ventilation shaft hatch;
• supply of electrical power necessary for the operation of the exhaust device.

Important! When preparing a place to install a wall-mounted hood, the main thing is to ensure that it is positioned strictly symmetrically above the gas stove, since even the slightest deviation of the body to the side reduces the efficiency of the device by 10 - 20%.

Direct installation of the hood at the place of its operation is carried out in the following sequence:

• First, the fastening points are carefully marked, taking into account the location of the supporting elements on the rear wall of the case (for these purposes, it is most convenient to use a pre-prepared template);
• after that, in accordance with the markings, holes are carefully drilled in the wall into which dowels are driven;
• then the supports used to hang the body are fixed in the dowels using bolts;
• At the final stage of installation, all that remains is to hang the hood itself on the prepared supports (watch the video).

Note! During trial hanging, it is necessary to check the correctness of its orientation in various planes, which is verified using building level and can be adjusted by changing the position of the supports (their design allows for adjustment within small limits and allows you to hang the hood quite comfortably).

Installation of air ducts and power supply connections

• outlet channels for a wall-mounted kitchen hood are assembled from relatively short and straight sections with minimum quantity bends, the radius of which should be chosen as large as possible;
• when using corrugated hoses as a discharge channel, their bending angle should not be less than 90 degrees;
• It is also not recommended to narrow the outlet section of the air duct, which can lead to increased noise;
• The hatch of the ventilation shaft to which the air duct is connected must be completely cleaned of all contaminants accumulated during its operation.

The operation of the exhaust mechanism requires an electrical network, the supply of which must be provided in advance. As a rule, products of this class are equipped with a cord with a plug, for connecting which a specially equipped socket with a grounding contact must be used.

Important! To avoid heating, such an outlet should not be located above the area where the hood is located.

Conclusion

From our description it follows that hanging a hood over a gas stove is not at all difficult, as you can see by watching any video on the relevant topic posted on the Internet. From these videos you will learn how to install kitchen hood above the stove, as well as existing methods its connection to existing communications.

Many people today are interested in how to install a hood over a gas stove.

The modern kitchen is cluttered with all kinds of household appliances. Not a single person these days can imagine life without a refrigerator, microwave, stove, etc. The same mandatory elements include a range hood. Finding out how to install it will be useful for everyone.

Why do you need a hood?

First, let’s find out why a stove hood is needed in principle. Let’s say right away that the absence of this attribute in the kitchen can lead to a number of unpleasant moments. The mere fact is that smoke and steam will accumulate in this room, and then all this will lead to gradual destruction facing materials, is no longer good. In addition, the cooking procedure on the stove will go much better if a reliable device absorbs unnecessary fumes or removes them outside.

Varieties

As a rule, there are several types of hoods for installation:

• Fireplace type;
• Built-in;
• Filtering;
• Air intake;
• Ostrovny;
• Corner;
• Wario and so on.

In addition, exhaust systems for stoves also differ in filters:

• Hoods with a metal filter are also called grease traps. Their installation is carried out only if the kitchen is equipped with a shaft for ventilation, since otherwise installation above the stove is useless. Such devices absorb unpleasant fumes and fumes much better if equipped with aluminum filters;
• Hoods with carbon filter installed as a separate attribute (not necessarily directly above the stove). They eliminate perfectly bad smell and are air recirculators.

As you can see, some hoods are capable of cleaning a room by dispersing air with evaporation, passing it through a filter, and then returning it back. Other units equipped with a metal filter completely draw in air without filtering and exhaust it outside.

Recently, universal models have begun to be produced that simultaneously perform both output and filtering. The owner chooses the most comfortable mode for him and adjusts it manually.

In some apartments it is not possible to connect the hood to the ventilation (labor-intensive process of connection and installation, unaesthetic final result and other reasons). Then you have to limit yourself to the recirculation mode, when the unit only filters the air above the stove.

Note! But in this case, you will need to know that this mode is most effective on certain installed hoods with carbon filter.

Productivity or efficiency

As a rule, models of exhaust systems are capable of pumping different quantities air (200-1200 cubic meters per hour). But the top rating of hoods is not the model that is more powerful, but the one capable of pumping air at a speed of 500 m3/hour.

The fact is that to calculate efficiency, you need to multiply the volume of the room by 10, and then multiply the result by 1.3. This will give the final performance of the unit, which, carrying out filtration in medium mode (without “overexerting” and without creating excessive noise), will provide excellent purification. This will be the highest efficiency.

Attention ! The passport for a hood model that simultaneously operates in 2 modes usually indicates the power in the mode of removing fumes into the shaft. This means that filtration through another mode will be 40 percent weaker, since its loss when passing through the filter is inevitable.

Among modern hoods, there are no such hoods that would not make any noise after being installed above the stove. This, of course, does not mean that perfect option with the required performance and with the least noise is impossible.

Note! So, the quietest of installed systems the hood is equipped with a motor sitting in a plastic box with soundproofing properties. The unit does not come into contact with the body at all, as it is protected by special gaskets. And still - 36 dB of noise cannot be avoided.

When choosing a range hood system for your kitchen, you should try to find a model with flawlessly functioning controls. Modifications with “pseudo-sensory” control are considered the most rational. Their microphones are perfectly protected from clogging. Network surges are not as bad for such hoods as for expensive options with touch control.

Installing a hood through a cabinet

The process of installing a hood over a gas stove depends on several things. The type of this kitchen attribute, the location of the shaft, the filtration method, and much more are taken into account.

Installation of an anti-return mechanism (clacker)

Let's first consider how to install a firecracker:

• It is recommended to start by making a cracker over the stove. Galvanized iron or just tin (aluminum is an ideal option) are quite suitable for this.

Note! If you don’t want to tinker, you can purchase a ready-made firecracker sold in stores. This element must be installed in front of the shaft itself.

• For maximum convenience, it is advisable to place the case on a cabinet that hangs above the stove.

Advice ! Initially, the housing is installed quickly. After installing the cabinet, all cracks must be sealed with foam, and the cabinet is firmly glued. This eliminates the possibility of resonance.

• We do not install the firecracker body the first time. First you need to mark the locations of the holes by attaching the product. The cabinet is removable for convenience, and the desired shape is ensured inside.

Advice ! To make it easy to cut the required shape in the cabinet, you must first drill a few holes, and then insert a jigsaw into one of them and start cutting.

• Be sure to make holes in internal shelves cabinet, if any, under the air duct.

Note! Also, don’t forget to make a hole in the top wall, keeping the required margin.

Air duct

We do the following:

• We insert the sheet into the holes made, giving it a square shape at the top of the cabinet;
• We cut it with a small margin, be sure to cut the corners and bend them outward;
• We attach the corrugated cabinet to the wall. We treat all joints and cracks with silicone so that the power of the system does not decrease;
• We fix the product on the cabinet;
• Now we attach the hood to the cabinet, screwing it tightly;
• We place the sheet on the hood, securing it with a clamp;
• We connect the air duct to the shaft, integrating both elements with a universal connector, as shown in the photo;

Advice ! When installing ventilation, you should try to minimize pipe bends as much as possible.

In this way, good traction will be ensured, because a large number of turning the pipe reduces power. She is lost by almost 10 percent .

Standard installation

Not all owners agree to hang a cabinet above the stove, considering it impractical. Indeed, such accessories quickly deteriorate from steam and high humidity, although they provide the hood with an aesthetic appearance.

Note! In addition, most wall cabinets are narrow, and this does not allow the installation of wide hoods in them.

So, to install the exhaust system, do the following:

• We make a rectangular frame from the corners. It will act as reliable support for the body;
• Instead of clamps securing the case to the wall, you can use special self-tapping screws;

• We connect the current to the hood.

Attention ! When connecting, do not forget to take into account the grounding moment, so that when the fans rotate, possible voltage is diverted to the side.

Important points

When installing the hood, you need to pay attention to the following points:

• The standard installation height of the hood above the gas stove should be average. In other words, it should be set neither too low nor too high.

Note! As for the exact dimensions, there is no way to indicate them, since it depends on the specific room, the size of the gas stove and the type of hood. Nevertheless, an approximate height can be given - 750 mm above the slab at least.

• It is important to regularly monitor your hood filters. If this is not done, then they will fail, and this will lead to damage to the unit itself;
• It is also recommended to wash filters frequently to remove grease, otherwise a large amount of accumulated substance can lead to fire;
• The exhaust system should be the same size as the stove, but not wider than it;
• The hood must be installed in a constant position relative to the cooking area.

Note! The fact is that if the hood is offset in relation to the stove even slightly, this will have an extremely negative effect: the steam will not come out effectively enough.

• It is also necessary to ensure that the hood is equipped independent system power supply It is advisable to prepare a special socket.

Note! You must also remember to ensure that the hood is grounded to ensure safe operation of the unit.

• During installation, safety precautions must be observed. If possible, it is better to ask loved one to protect you when securing the hood.

Let us remind you that the hood must be cleaned at least 1-2 times a year to remove fumes. This will eliminate the risk of fire. Now, knowing how to install a hood over a stove, you can save a lot on the services of specialists. Good luck with your work!

Quality and specifications The hood installed in your kitchen determines, first of all, the cleanliness and freshness of the air, and, accordingly, the level of comfort and coziness in the apartment. If your kitchen is the place where you often cook Tasty food, the presence above the gas stove is doubly important. Let's find out what features installation has different types appliances and what the installation height of the hood should be.

What types of hoods are there?

There are two main types of kitchen hoods: with system and with.

In the first case, the device is powered from the mains and operates on the principle of internal circulation of air flow. Dirty air goes inside, is cleaned and returns outside. For small kitchens This type of hood over the stove will be the ideal solution.

If the kitchen is large and something is constantly being prepared in it, it is recommended to hang the unit with a connection to an air duct, which will simply remove dirty air from the room. In addition, such models have greater productivity.

Features of operation

The hood itself is not complicated. It is controlled via a simple mechanical control panel. It can have both push-in buttons and slider switches. The first, being in characteristic position at the same level with the body, indicate the activation of one or another function of the device, and the latter allow you to quickly change operating modes or turn the device on/off. These control options are typical of cheaper units that can be hung above a gas or electric stove.

The latest developments are equipped with popular various industries sensor industry. Any element of such a system requires only a light touch with a finger to activate or deactivate the function for which it is responsible.

Types of hoods according to installation principle

Based on the installation features of a particular model, hoods are classified according to the type of installation:

• , just like a fireplace, is mounted on the wall and will take up enough large space. Such a device will be an excellent solution not only for modern, but also for classic style.
• An island hood is attached to the ceiling in any part of the kitchen and is used when the electric or gas hob is located in a non-standard location, placed in the center of the kitchen and not blocked by any cabinets. It will be a good addition to absolutely any design.
• The corner type of device is installed in the corner of the kitchen; it will solve the problem of ventilation and air purification if, due to the layout or location of communications, the stove is located in the corner of the kitchen room.
• A flat hood is mounted on the wall, most often under a wall cabinet.
• Built-in models are mounted entirely in a wall cabinet.

General installation rules

If you decide to install a hood without the help of a specialist, you need to know some rules:

1. The hood is hung above the gas stove at a level of 60 cm or higher. But for its most effective operation and good addition interior, the height of the hood fastener is calculated individually. It is not for nothing that standard operating recommendations indicate ranges that allow one to take into account factors such as hood power, kitchen design, and the height of the person who most often cooks at the stove.
2. The width of the hood should not be narrower than your stove. Therefore, it is not recommended to buy or order, or install a hood before installing a gas stove.
3. If the hood is electric, then the outlet from which it will consume electricity should not be located above the stove to avoid a fire.
4. When connecting the device directly to the duct, a pipe with a minimum number of bends should be used.

Installation of a hood with a carbon filter

This type of hood is very easy to install even for non-professionals. Using a level, the height and location of the device are calculated, after which places for future fastenings are marked. After this, using simple manipulations with a hammer drill, holes are made for fastenings. The device is attached to special hooks that will hold it firmly and securely.

Installation of a flow-through hood with an air duct

The process of hanging the hood with connection to the air duct occurs, as in the previous case, using fasteners. The device must be leveled horizontally and hang at the permitted distance from the stove. Next, it is installed, which must necessarily match the diameter of the ventilation duct in the wall, which will ensure no power losses.

After installation, you must check that everything was installed correctly and functioned properly.

Installation features

Distance between hood and hob The stove is measured from the bottom edge to the burners. The unit should be mounted exclusively by level, since the possibility of adjusting the position in the future is excluded.

Before installation, you need to think carefully about choosing a location again, because the device must have access to the ventilation shaft and power supply at the same time. For this reason, the location of all communications is indicated on the kitchen plan.

In case of overhaul The location of the hood is calculated and drawn on the kitchen plan along with other electrical appliances. If the only question is replacing certain equipment, then you will have to adapt to existing circumstances.

When using gas stoves, it is necessary to clean the kitchen atmosphere from combustion products, and an exhaust device is simply vital. The height of the kitchen hood above the gas stove determines the degree of efficiency of the system and is the most important parameter in ensuring clean air.

Lack of air purification leads to discomfort and constant intoxication of the body. A hood installed at the wrong height above a gas stove can also make its presence useless, or complicate the cooking process. Optimizing the installation of equipment will create the necessary comfort for the kitchen owner.

In general, a kitchen hood is a structure that provides forced intake of contaminated air in order to clean it from various fumes, products of incomplete combustion of gas, smoke components, suspended impurities and odors that form above the stove during cooking. Exhaust systems contain a housing, an air intake, a set of filters and electrical ventilation elements.

According to the principle of operation, hoods are divided into two main types:

1. The flow-through type of device is based on the forced removal of contaminated air into the ventilation system of the house, i.e. outside the kitchen. Such a system provides, practically, complete removal pollution from the premises a short time, but requires an influx of fresh air mass from outside.
2. The circulation type of hood does not remove air from the room, but cleans it by passing the contaminated air through a filter system and then returning it to the kitchen. The main advantage of this type is the absence of additional highways; and the disadvantage is the increase in time complete cleaning air.

Classification of hoods

The design of the installation determines the location of the hood in the kitchen and the conditions for its installation. Based on the installation features, it is customary to distinguish the following types devices:

• the suspension system usually has flat view and is fixed at the bottom of a shelf or wall cabinet directly above the stove;
• the built-in type is a hood, the body of which is located inside a cabinet or dome above the stove;
• the wall-mounted version of the hood is fixed to the wall surface above the gas stove;
• the corner type is designed so that the hood can be hung in the corner of the room if the stove is moved to the end of the wall;
• the island variety is needed in large kitchens, where you need to hang the hood from the ceiling in the center of the room.

Based on the design and shape of the air intake, three main types can be distinguished: flat horizontal, vertical and dome-shaped installations. U flat designs the bottom surface is rectangular blinds; sometimes limited by a low side. They must be hung horizontally above the stove at a certain height. Available in widths of 50 and 70 cm. Vertical design provides for an inclined arrangement of a rectangular hood, close to the vertical direction. In the upper part, it is possible to make a guide visor.

The most common is the domed variety, designed like a tent over a stove. Such hoods are sold in widths of 50, 60, 70, 90 and 120 cm. The depth of the dome (the height from the bottom of the dome to the hood louvers) is usually 0.5 m. The total height of the tent does not exceed 103 cm.

By design features, in terms of the versatility of installations, the following types are distinguished: stationary, removable and retractable (folding) version. The last type of hood is typical for a flow-through system and provides a retractable air intake, which is introduced into the cooking area only when air purification is needed.

Hood location conditions

The main parameter for the installation location is the distance from the stove to the hood. Before hanging the device, you need to decide at what height to hang the hood. Typically, the recommended installation height for the hood is indicated in the equipment instructions, and these recommendations must be followed. If there are no instructions, optimal height above the gas stove is determined taking into account certain conditions.

The distance between the bottom of the hood and the stove is determined by the following basic conditions:

• safety determines the minimum permissible distance between open flame and plastic, to prevent spontaneous combustion (safe distance - at least 65-70 cm);
• the lower limit of lowering the hood is determined by the convenience of the housewife when preparing food - she should have free access to the largest pots;
• The upper level of height is determined by the ability of the exhaust to draw air from the lower, most polluted layers.

In general, the normal height at which a hood can be hung is considered to be within 70-90 cm. But to optimize the operation of the equipment, this value should be clarified. First of all, the cook should be comfortable, which means taking into account his height. If a person is tall, then the size of the working area should be increased to the maximum, and for this you need a hood with the greatest power.

Influence of hood characteristics

The choice of distance between the hood and the gas stove is significantly influenced by the power (performance) of the equipment and the area of ​​the air intake, as well as the type of its location. Weak hoods with a capacity of 240-300 cubic meters. m/h will have to be hung no higher than 75 cm. Modern powerful installations are capable of cleaning more than 600 cubic meters. m/h, which makes it possible to increase the height of the working area.

Another important parameter is the size of the hood. The width of the hood should not be less than the width of the gas stove, otherwise it will not cover the entire surface of the source of air pollution. Why is such an installation needed? On average, the width of the slab is 60 cm; therefore, hoods measuring 60-70 cm cannot be raised high. To increase the distance, install a device measuring 90 cm.

The solution to the question of what the installation height of the equipment should be is influenced by how the air intake is located - horizontally or inclined. When placed at an angle, the lower edge of the hood should be lowered below the recommended distance - up to 55 cm.

When choosing a safe distance, you should take into account the fact that the material of the device body practically does not affect this value, since the risk of fire is determined by the deposition of fats, soot and other substances that can ignite from an open fire or overheating of the material on the surface of the air intake. Minimum distance is established based on this condition.

Based on experience in operating hoods, The following height for the bottom surface of the device is recommended:

• standard 4-burner gas stove – 75-85 cm;
• gas stove with an inclined hood - bottom line: 55-65 cm;
• electric stove – 65-75 cm.

Different manufacturers require compliance different conditions installation Metida60W hood from Shindo with a capacity of up to 420 cubic meters. m/h is mounted at a height of 75 cm (at the same time, it is not recommended to use the device above the burner without installed utensils). Bosch DWW09W650 hood with a capacity of up to 650 cubic meters. m/h has a telescopic air intake that can be lowered to a height of 65 cm from the burner. The domestic installation Saturn M60 has a capacity of 245 cubic meters. m/h, it is recommended to hang it at a height of 75 cm, as indicated in the instructions.

Conclusion

When installing the hood, it is necessary to monitor the coaxiality of the location of the equipment and the stove - displacement of the device relative to the source of pollution will make the choice of the location height incorrect, since the intake will not be able to cover the entire area of ​​pollution.

Hood height above gas stove important factor in ensuring the efficient functioning of equipment. Underestimating the parameter leads to a risk of fire and a decrease in the comfort of servicing the stove; overestimation leads to insufficient air purification.

It’s hard to imagine a modern kitchen without this household appliance like a hood. Its main purpose is to remove contaminated air masses and unpleasant odors outside the occupied space. Today, no one counts on ventilation in the form of boxes, because over time the channels become dirty and narrowed, as a result of which their efficiency greatly decreases. Therefore, a hood installed above a gas stove is perfect solution to remove dirt coming from the stove.

Classification exhaust devices is based on the principles of operation and methods of installation of devices. There are two positions that differ from each other in the operating principle of the device. Accordingly, their technical component differs.

• Flow hoods. Simple model, in which the fan is installed. Their main task is to remove polluted air to the street or into the ventilation system of the house.
• Recirculating hoods. They are designed with filters through which polluted air is driven through using a fan. It is cleaned and returned back to the premises. In this case, no connections to the street or ventilation ducts are required. Therefore, installing such a hood above the stove is the simplest.

Recirculating hoods, in turn, are represented by a wide range of models:

• Wall-mounted - they are mounted to the wall above the stove. The design of the device has mounting holes through which holes are made in the wall. Fastening is most often done with metal dowels. Similar type hoods resemble a dome in their shape, which is why they are also called dome or fireplace hoods.
• Hanging. These are the most common models because they are attached to the bottom surface of a wall cabinet that is hung above hob. Mounting method: bolted connection to the cabinet. That is, before hanging the cabinet and the hood, you should place them on the table next to each other and mark the joints. Then, in the lower plane of the cabinet, a drill and a drill bit are used to make through holes. And then you can do it in different ways: install and secure the cabinet on the wall, and then attach the hood to it with bolts, or make the connection on the table, and then hang the entire structure on the wall.
• Built-in. Today these models are very popular. This is due to the fact that you do not have to select the device by color and shape, because it will be hidden in a wall cabinet specially made for it. Only the control panel will be visible. Therefore, before installing a hood over a gas stove, you need to take its dimensions and make a cabinet for them. Or, conversely, select the right device to fit the size of the cabinet. However, before this you will have to accurately calculate its power so that it matches the dimensions of the kitchen appliance. As for installation, there are no difficulties here. The hood is simply installed in the cabinet and closed with a door.
• Inclined. This type of hood is gradually gaining popularity due to the unusual installation. The device consists of two parts: a hood and a mounting panel, which is fixed to the wall above the gas stove. The equipment is made as follows: a horizontal line is applied to the wall above the slab, then the mounting locations for the holes are marked, after which the panel is applied to the drawn line, and an exhaust device is inserted into it.
• Island. Installing such a hood over a gas stove is a special case. Firstly, the device received its name only because it is installed above the stove, which is part of the island kitchen set. Secondly, the hood is attached to the ceiling using special collets and pins. Installation occurs in this way: collets are attached to the ceiling, pins are hung on them, which are attached to the first ones through a thread. The studs are attached to the hood in the same way. Then the resulting fastening system is closed with a box. If a recirculating hood model is installed above the island, then the decorative box does not need to be used. This design is secured with cables that will be visible. There are designs that are fastened using a combined method, that is, both pins with collets and cables are used.
• Angular. These are ordinary wall-mounted units that are attached directly to the wall. Only they are mounted not to one wall, but to two adjacent to each other, that is, to the corner of the room.

Ventilation duct installation

A ventilation duct is a part of flow devices that are made of plastic in the form of round or rectangular section, or in the form of a corrugated pipe.

In hoods, the outlet pipe has a circular cross-section, so it is ideal if ventilation duct will be round. Today, manufacturers offer various adapters: with round section to rectangular, from one diameter to another. That is, it became possible to use any pipes, regardless of their shape and size. The main thing is to choose the adapter accurately.

The pipe sections are connected to each other through double-sided couplings or bends. Typically, pipes have a slightly smaller diameter than fittings, so they fit easily into each other. At the same time, complete tightness of the joint is maintained, which is very important in ventilation system. A corrugated pipe is a single channel that can be bent if necessary. On the hood it is also connected through an adapter. Fastening is done with plastic or metal clamps.

Technical indicators

To accurately answer the question of how to properly install a hood over a gas stove, you should additionally identify two more positions:

1. Hood installation height. As for the gas stove, this size should be 85 centimeters.
2. Device power. It is calculated using a formula that includes the volume of the room (kitchen) and air circulation. The first is the floor area multiplied by the height of the ceilings. The second is a standard value, which is indicated sanitary standards. For the kitchen this figure is 12 m³/hour. But for the room where the gas stove is installed, this coefficient is 15-20 m³/hour, depending on the intensity of use of the device.
