Installing the hood at the correct height means safe and efficient operation.
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 cooker hood above the gas stove determines the degree of efficiency of the system, and is the most important parameter in ensuring the cleanliness of the air.
Lack of air purification leads to discomfort, constant intoxication of the body. A cooker hood installed at the wrong height above a gas stove can also make it useless or make cooking difficult. Optimization of the installation of equipment - will create the necessary comfort for the hostess of the kitchen.
Features of exhaust systems
In general, a kitchen hood is a structure that provides forced intake of polluted air in order to clean it from various vapors, incomplete combustion products, 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.
The main difference between the two types of hoods is that the exhaust hood requires an air duct in order to remove air from the kitchen. Recirculation opposite - purifies the air with a charcoal filter and feeds it back to the kitchen
According to the principle of operation, the hoods are divided into two main types:
- The flow-through type of device is based on the forced removal of polluted air into the ventilation system of the house, i.e. outside the kitchen. Such a system provides, in practice, the complete removal of contaminants from the room in a short time, but requires an influx of fresh air mass from the outside.
- The circulating type of hood does not remove air from the room, but purifies it by passing the contaminated stream through the 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 an increase in the time for complete air purification.
How to properly hang a hood over a gas stove
What is the distance from the hood to the gas stove?
Although usually houses have a ventilation system. But often it does not cope properly with its functions, especially in a room such as a kitchen. When we use a gas stove, we may come across unpleasant smells of recycled gas, but this is not only unpleasant, but also hazardous to health. In principle, vapors always occur on the stove, which carry certain odors in themselves and they will be absorbed into curtains and other kitchen utensils. After that, you need to clean more in the kitchen, and therefore spend more time and energy.
How to properly install a hood over a gas stove
The ecology of your room and the comfort of spending time in the kitchen will depend on the correctly selected model.
There are two types of exhaust devices
Let's start with the first kind of device - this is wide known type of device with a circular built-in carbon filter... which works according to the simple principle of air recirculation. Due to this, the air does not leave your room, but circulates, is filtered and returns back to the room. These devices are called everyday or filter devices.
Their second type, serves to remove air from the room irrevocably, this is a special hood with forced intake of unwanted odor and smoke... To do this, it is necessary to output the gas hood to the ventilation shaft or to the street. This type of hood is intended for a large large kitchen. This type of exhaust device is noticeably higher and of better quality than that of a circular one. Therefore, these types of this device are most often installed in kitchens. Moreover, in most multi-storey buildings, there are ventilation shafts, which simplifies the installation of such equipment.
Basic installation guidelines
At what height should the hood be hung? The height of the hood above the gas stove must be at least 65-70 centimeters.
The dimensions of the intake part should preferably correspond to the dimensions of the stove.
The electrical outlet should be located in a suitable place above the stove and so that it does not get hot from the stove.
The corrugated pipe should have as little bend as possible for good air passage. Then, when the mechanism is turned on, the loss of efficiency of the device will not wake up.
How to hang a cooker hood?
The installation of a filter hood with a circular filter does not require the most special skills or special training and special efforts. To install, we need a regular level. As we remember, the distance from the hood to the stove is 65 - 70 cm. Therefore we measure the height we need and carefully draw a straight line... Then we measure with a tape measure the distance from the hole to the hole for fastening, which are located on the hood itself. We transfer these dimensions to our line, so that it is located exactly above the slab. Next, we drill holes with a perforator. We insert plastic plugs into the holes and screw our equipment to them.
Some people decide to screw the hood to the wall cabinet. In this case, we, according to the same principle, mark at the desired height where to screw the equipment and fasten it with self-tapping screws on wood.
If you are installing a forced draft hood into a ventilation shaft, it is important to install a corrugation or a plastic pipe so that the pipe end connection is strong and without holes so that there is no loss of efficiency.
It is of fundamental importance that the diameter of the pipe matches the air intake opening in the wall, in order to avoid loss of quality air pumping power. After completing the installation procedure, the equipment should be tested in action to verify that the hood is installed correctly.
Tips from the masters
If, for some reason, you need a separate socket to connect your equipment, then it is advisable to hide all the wires leading to it in a cable channel or in elements of a kitchen set... It is also possible to hide it in the decorative elements of the decoration of the kitchen area.
If you have tiles glued at the attachment point, then be very careful when making holes so as not to break it. For this, it is better to use special drills.
Provide in advance in the power line a triggering device-automatic for emergency shutdown of the device, in the event of a voltage drop in an emergency.
Maintenance
Regardless of which hood you buy is expensive or cheap, respectively high quality or not very good, if it is not properly maintained, then breakage of ventilation parts may occur... With such breakdowns, the equipment can continue to work, but the efficiency of the ventilated system decreases. Accordingly, the room is not ventilated properly, therefore, the question that has arisen "how to mount the hood in the kitchen area" is followed by the question "how to maintain it correctly?"
If the hood has a built-in charcoal filter in its design, then it is necessary to make its replacement in a timely manner... Read about the service life on the instructions for the filters. This is the most important rule for suspended hoods, which belong to filtering devices.In this case, the filter is the "heart" of the device. So keep an eye on it and change it regularly.
- Clean the hood regularly. Burns, grease, etc. quickly accumulate on it.
- Make sure that the fastening on the pipe is firm and there is no play at the pipe joints.
- the height of the hood above the gas stove fluctuates in the region of 75-85 cm;
- the installation height of the hood above the electric stove is 65-75 cm.
We sincerely hope that this article will help you understand how to properly install the hood, as well as properly operate and maintain it in order to enjoy the fresh air in your daily kitchen.
At what height should the hood be hung?
A kitchen without a hood is not very pleasant - during cooking, smells spread throughout the apartment, are absorbed into the wallpaper, into the curtains and completely cease to seem fragrant. That is why the question of the advisability of acquiring a hood cannot stand, it is obvious that one cannot do without it. But after the purchase, other important questions appear, one of which is - at what height should the hood be hung?
What is the optimal installation height for the hood?
To begin with, the height of the hood installation above the stove is always indicated in the description of a particular model. Of course, this is not a clear mark, but a certain range in which you can vary, starting, for example, from the design of the kitchen or from the height of the hostess. However, if the instruction is lost or you do not trust it, there are standards that determine the distance from the hood to the stove. First of all, for proper installation, it is important to consider the type of hob:
If we are talking about an inclined hood, then the height of the lower part:
- above the gas stove should be about 55-65 cm;
- above electric - 35-45 cm.
Also, the distance between the stove and the hood can be changed within these 10 cm, depending on the power of the device for purifying the air. For example, if a low-power kitchen hood is fixed at the maximum allowable distance, there is no guarantee that it will fully cope with its task.
Why is it important to stick to limitations?
The recommended installation height of the hood is an indicator that cannot be neglected, because the quality of the equipment and safety depends on it. If you go beyond the upper limit of the indicated distance, the efficiency of the hood will significantly decrease, it will not capture all the steam. If you go beyond the lower limit, then the likelihood of fire increases. In the case of a gas cooker, grease dust deposited on the hood filters can be ignited by an open fire. In the end, a low draft will simply interfere with the cooking process.
Where to install the outlet for the hood?
The height of the outlet for the hood is usually 2-2.5 meters. It is installed above kitchen cabinets (10-30 cm from the upper border). It is important to take into account how the air duct will pass; it should not block the outlet. That is, the rosette must be offset 20 cm to the left or right of the center of the hood.
Hood over a gas stove: types, requirements and installation procedure
The need to install a special hood above the stove is explained by the desire of users to get rid of extraneous odors and other vapors generated in the kitchen during cooking. At the same time, it is possible to ensure the required efficiency of air purification in the room only if certain rules and recommendations are fulfilled, determined by the relevant norms and standards. In this article, we will acquaint you with the existing types of exhaust structures and consider the procedure for their installation using one of the most common models as an example.
Types of hoods for the kitchen
Hood in the interior of the kitchen
Currently, a wide range of kitchen hoods is presented on the domestic market of household appliances, which, according to their design, are divided into the following types:
- suspended structure, which is one of the most convenient in installation and practical exhaust devices, suitable for most ordinary users. With all the listed advantages, such a hood, however, is characterized by insufficient performance;
- an exhaust device built into the walls or ceiling, providing the required efficiency in removing odors and vapors from premises 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 nearby;
- the so-called "island" hood, mounted in the center of the kitchen area and providing air exchange throughout its volume (including above the gas stove).
Auxiliary elements (air ducts)
Examples of air duct execution
As air ducts, through which unpleasant odors and vapors are discharged to the hatch of the ventilation shaft, special air ducts are used, made in the form of:
- corrugated pipe;
- rigid metal box;
- PVC pipes with smooth walls.
The advantages of corrugated pipes include their flexibility and relatively low cost. The disadvantage of this budget version of the duct is the need for constant care during operation. The metal box used as an air duct is more convenient in operation, but it will require significant expenses from the contractor. The most optimal option is the use of a PVC pipe, which is not only easy to install, but also does not require special care. Unlike other air ducts, such a pipe is installed strictly above the hood.
Hood installation requirements
Suspended hood
The procedure for installing a kitchen hood will be considered by us using the example of a simple hinged system, the installation of which involves the fulfillment of the following requirements:
- the dimensions of the intake opening must correspond to the size of the gas stove, which ensures the most efficient removal of contaminated air;
- the height of the hood above the surface of the stove should not be less than 50-60 cm (the optimal distance from the heating elements is about 75-80 cm), which provides comfortable working conditions. 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 capacity of the exhaust device must correspond to the volume of the serviced room and provide air renewal in it at least 10 times a day. To calculate the exact value of this indicator, it is necessary to determine the main dimensions of the 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 indicator of the intensity of air exchange (1.3 - correction factor);
- in the event that your house does not have a separate ventilation shaft with access to the kitchen, it is recommended to use a flow-through exhaust device with variable capacity, operating on the principle of air mass recirculation.
Note! Connecting such hoods to an existing ventilation shaft can disrupt the operation of the entire exhaust system as a whole. In addition, flow-through devices are not recommended to be turned on at full power (in the maximum performance mode) for a long time.
Hood housing installation procedure
Mounting height of the hood body
Installing an extractor hood above a gas stove involves the phased implementation of a whole range of working operations of the following nature:
- hang the hood of the hood directly above the stove;
- installation of branch ducts, ensuring their reliable connection with the hood and the hatch of the ventilation shaft;
- supply of electrical power required for the operation of the exhaust device.
Important! When preparing a place for installing a hinged-type hood, the main thing is to ensure that it is located 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, a careful marking of the attachment points is made, taking into account the location of the supporting elements on the rear wall of the case (for this purpose, it is most convenient to use a pre-prepared template);
- after that, in accordance with the markings in the wall, holes are carefully drilled into which dowels are driven;
- then in the dowels with the help of bolts the supports used for hinging the body are fixed;
- at the final stage of installation, it remains to hang the hood itself on the prepared supports (see video).
Note! During a trial hanging, it is necessary to check the correct orientation in various planes, which is verified with the help of a building level and can be corrected by changing the position of the supports (their design allows adjustment within a small range and allows you to hang the hood quite comfortably).
Air duct installation and power supply connection
Hood with corrugated duct
When installing the air duct, we advise you to pay attention to the following important details:
- outlet ducts for a hinged-type kitchen hood are recruited from relatively short and straight sections with a minimum number of bends, the radius of which should be chosen as large as possible;
- when using corrugated hoses as a discharge channel, the angle of their bending 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 an increase in the noise of its operation;
- the hatch of the ventilation shaft, to which the air duct is supplied, must be completely cleaned of all contaminants accumulated during its operation.
For the operation of the exhaust mechanism, an electrical network is required, the connection of which must be foreseen in advance. As a rule, products of this class are equipped with a cord with a plug, for the connection of which a specially equipped socket with an earthing contact must be used.
Important! In order to avoid heating, such a socket should not be located above the area where the hood is located.

Hood classification
The design of the unit 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 between the following types of devices:
- the suspension system is usually flat and is fixed at the bottom of a shelf or wall cabinet directly above the stove;
- built-in type is a hood, the body of which is located inside the cabinet or dome above the stove;
- the wall-mounted version of the hood is fixed on 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 slab is moved to the end of the wall;
- the island variety is needed in large kitchens, where it is necessary to hang the hood from the ceiling in the center of the room.
The main types of hoods
According to the design and shape of the air intake, three main types can be distinguished: flat horizontal, vertical and domed installations. For flat structures, the bottom surface is rectangular louvers; 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. The 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 guiding visor.
The most common is the domed variety, made like a tent over a slab. Such hoods are available 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 louver of the hood) 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 latter type of hood is typical for a flow system and provides a retractable air intake, which is introduced into the cooking area only when air purification is needed.
Cooker hood air duct
One of the stages of installing the hood is the selection and installation of air ducts. Air at room temperature is removed from the kitchen, therefore there are no special requirements for air ducts and any can be used. Three types are commonly used:
- Aluminum corrugated sleeve. It is good because it is easy to give it the desired shape - it bends easily at any angle. Simply take a piece of the desired length and shape it to the desired shape. Disadvantage: the hood will be noisy as the air flow causes noise and resonance. The second negative point is that the surface is ribbed, which creates additional difficulties for the air flow. Well, one more drawback is that it is difficult to care for: soot with dust is hammered into the grooves, it is difficult to clean it.
- Plastic (PVC) round duct. Convenient to use round polymer pipes. The air duct of the required configuration is assembled from shaped elements - bends, bends, adapters, couplings. They are connected to the pipe due to the presence of extensions on the fittings. To prevent the elements from separating during operation, the joints can be coated with glue (liquid nails or Moment). Another option is to fasten it with self-tapping screws - three to four pieces for each connection. The advantage of PVC air ducts for the hood is that they are "quiet", smooth inner walls do not impede air movement, the outer ones are easy to clean. The disadvantage is the more complicated assembly process (compared to aluminum corrugation).
Types of air ducts for kitchen hoods
There is also a difference between plastic and corrugated ducts - the price. Polymers are more expensive. Despite this, if you have the opportunity to install a hood using PVC, install them. With the same cross-section, they provide more efficient air discharge and also produce less noise.
The cross-section of the duct pipes is determined by the size of the outlet on the hood. In the case of rectangular pipes, an adapter is used.
Dimensions of air ducts for hoods
Round air ducts are available in three sizes: 100 mm, 125 mm and 150 mm. This is the diameter of plastic pipes and corrugated sleeves. There are more cross-sections of flat air ducts and they are presented in the table.
Dimensions of flat PVC air ducts for hoods
How to choose the size? In the case of round pipes, their diameter must match the diameter of the exhaust outlet of the hood. It is very 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 - its sectional area should not be less than the sectional area 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 the hood and use an aluminum corrugation for the air duct, you will need to think about how to attach it to the cabinet and to the ventilation. To do this, you will need clamps of a suitable 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 air duct pipe. In the lower part there are openings for removing air from the kitchen using natural circulation at a time when the hood is not working.
Fastening the corrugation to the grille on the wall
For fastening the corrugation, a lattice with a protrusion is suitable - there is a side around the hole of several centimeters, on which the corrugation is put on, after which it is fastened with a clamp of a suitable size.
The corrugated air duct is attached to the hood by the same principle. 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 route, but on average 1 fastener per 50-60 cm is sufficient. Pipes are inserted into these latches during installation with little effort.
If the duct is to be fixed to the ceiling, the same fixings can be used. But if it is necessary 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 to them with small PVC screws an air duct for the hood.
Hood location conditions
The main parameter of the installation location is the distance from the plate to the hood. Before you hang the device, you need to decide at what height to hang the hood. Usually, the recommended installation height of the hood is indicated in the equipment manual, and these recommendations must be followed. In the case where there are no instructions, the optimal height above the gas stove is determined taking into account some conditions.
Keep in mind that the height of the hood above the stove directly depends on the type of the latter. If your stove is electric, then it is allowed to position the hood at a height of 65 cm.If it is gas, then it will be safer to place it at a height of 75 cm
The distance between the bottom of the hood and the hob is determined by the following basic conditions:
- safety determines the minimum permissible distance between an open flame and plastic, to prevent spontaneous combustion (safe distance - at least 65-70 cm);
- the lower limit for lowering the hood is determined by the convenience of the hostess when cooking food - she must have free access to the largest pots;
- the upper level of the height is determined by the ability to draw in air from the lowest, most contaminated layers.
In general, the height at which the hood can be hung is considered normal, in the range of 70-90 cm. But to optimize the operation of the equipment, this value should be clarified. First of all, it is necessary to ensure the convenience of the cook, and therefore take into account his growth. If a person is tall, then the size of the working area should be increased to the maximum, and this requires a hood with the highest power.
The main mistakes when installing the hood
Even experienced home craftsmen who repeatedly carry out various repairs in their apartment / house can make mistakes when installing the hood over the gas stove. And newcomers in this business and even more so.
For gas stoves, the recommended height of the hoods differs from the electric ones. This should be remembered before starting installation work.
The most common mistake is the wrong height for mounting the device. So, often the person responsible for the installation considers it unnecessary to spend his time reading the instructions and simply relies on the opinion of a neighbor / comrade who is authoritative in his eyes, who claims that 60-70 cm is enough.
This situation is especially common in kitchens where no one is cooking. After all, in order to brew coffee and heat pizza, an extractor hood is not needed. Therefore, the hood in this kitchen will play a decorative role for the time being. As soon as the hostess appears there, inspiringly sculpting culinary delights, you will have to buy a new one or reinstall the low-hanging hood.
The second mistake during installation is the insufficient width of the equipment. It should be remembered that for normal operation, the width of the hood must be the same as that of the stove.
Experts recommend planning the purchase of a cooker hood only after purchasing a gas stove. So it will be possible to choose the model that is optimal in width and height.
The third mistake is more related to design - it will not affect the functioning of the equipment. We are talking about the air ducts connecting the device to the ventilation shaft - it is advisable to install plastic in areas of open space. This will visually give a more sophisticated appearance to communications.
For air ducts that are hidden under a decorative casing, in a plasterboard box or in a false ceiling, you can use corrugation. Also, this option is acceptable for models of hoods that are mounted in a wall cabinet. The air duct will perfectly hide in the same cabinet - you just have to cut the corresponding hole for it.
The air duct made of metallized corrugation perfectly hides in the closet. If the camouflage option is not possible, it is better to choose a neat plastic pipe.
Another mistake is made by beginners when working with a hood with decorative glass. When installing it over a gas stove, you have to be extremely careful not to accidentally damage the decorative case. Under no circumstances should the equipment be lifted by holding onto the glass.
The fifth mistake is incorrect connection to the mains. This situation is fraught with not the most pleasant consequences if the current flows through the hood body. Basically, this problem occurs when a novice home craftsman directly connects the wires of the device with a power cable.
If the hood is plugged into an outlet, then it is important that the electric point is removed from the gas stove at a distance of 60 cm. Compliance with safety rules and regulations will prevent accidental ignition of the wiring.
The neat white plastic of the ventilation duct is not conspicuous in the kitchen. If you wish, you can choose a color to match the wall decoration or paint the pipe in the desired shade.
All mistakes can be avoided if you are responsible for each stage of installation work. Correct installation and connection of the hood above the gas stove brings you closer to an excellent result with every step. Well-installed equipment will delight any housewife and will last much longer than its operational life.
Influence of hood characteristics
The choice of the 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.
You can calculate the power of the hood using this table.
Another important parameter is the dimensions 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 slab width is 60 cm; therefore, hoods measuring 60-70 cm must not be lifted high. To increase the distance, a 90 cm device should be installed.
The solution to the question of what should be the height of the equipment installation is influenced by how the air intake is located - horizontally or with an inclination. In case of inclined placement, the lower edge of the hood should be lowered below the recommended distance - up to 55 cm.
When choosing a safe distance, one 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. The minimum distance is set based on this very condition.
Recommendations for installing the hood
Based on the experience of operating hoods, the following height is recommended for the bottom surface of the device:
- 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 oblige to comply with different installation conditions. Hood Metida60W 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 the cookware installed). Hood Bosch DWW09W650 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. 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.
Output
When installing the hood, it is necessary to monitor the alignment of the equipment and the plate - the 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.
The height of the hood above the gas stove is an important factor in ensuring the efficient functioning of the equipment. Understating the parameter leads to the risk of fire and a decrease in the comfort of servicing the stove; overestimation - leads to insufficient air purification.
