Ventilation devices are a necessary condition for cleanliness and comfort in the kitchen. They remove combustion products from the air and ensure that there is no burning on surrounding objects. Hoods protect furniture from small particles of grease and corrosive kitchen odors. But in order for ventilation to work reliably and efficiently, the distance between the hood and the stove must be correctly maintained.
According to the principle of operation, exhaust devices are divided into two types: circulation and equipped with an air duct. The first ones have carbon filters installed through which the air passes, is cleaned and returned back to the room. They are convenient for installation in small kitchens where there is no space for an air duct. In this case, the distance from the hood to the stove is kept small.
Exhaust devices of the second type are connected to the ventilation system. With their help, contaminated kitchen air is removed outside. Such devices are designed for installation in large rooms. Exhaust devices are also distinguished by design:
When purchasing a fume hood, it is better to consult with specialists regarding its power. In a small kitchen you should not hang a bulky, powerful unit, and for a large kitchen a weak hood is not suitable. The size of the exhaust hood must match the parameters of the hob.
Experts have developed optimal standard distances from the gas stove to the hood. The standard height of the hood above a gas stove is no lower than 75-85 cm; above an electric stove it is installed at a height of 65-75 cm. This distance must be strictly maintained.
If you hang the device higher, it will not absorb air well, causing fumes and odors to quickly spread throughout the room. If it is lower, it will interfere with cooking, and there is a risk of overheating of the device, which will cause its coating to deteriorate or ignite. To determine which hood is suitable for the kitchen, you need to consider the following factors:
- type of hob;
- room design;
- unit power;
- technical installation standards.
It is better to entrust the installation of the hood to specialists, but a person who is confident in his own abilities can do it himself. To install an exhaust device with air circulation, you need to calculate the installation height and mark the necessary points on the wall surface.
Holes for fastening elements are drilled in the wall. The hood is installed on self-tapping screws and hooks, which are included in the kit.
Units with an air duct are installed in the same way as circulation units. After installation, an exhaust pipe is mounted to the housing, then turned on to check operation. If the hood is not working well, then inspect the connections to the ventilation system and the integrity of the pipes.
Typically, air ducts are made of thick foil. In order not to disturb the design of the room, they are covered with boxes made of PVC or plasterboard. The most efficient duct design is one with short, straight pipes and few bends. If there are too many bends, they will interfere with the passage of air.
The electrical outlet for connecting the hood is mounted at a distance of 2.5 m from the floor. It should be located 10-20 cm above the wall cabinets, to the left or right of the air duct. For hoods, it is better to use electrical outlets with grounding. During sudden voltage surges, they will turn off and protect the device from burning out.
For devices to work effectively, they need to be monitored. There are several care tips:
- After each switching on, the device must be wiped clean from grease and dust.
- Do not turn off the hood immediately after cooking. It is left to work for a few more minutes so that it absorbs all the dirt.
- Carbon filters are changed every six months.
Properly installed hoods will clean the air in the room and ensure the cleanliness of surrounding objects. When purchasing, you should choose a model that matches the size of the kitchen, interior, and preferred cleaning method. During installation, for efficient and safe operation, the distance standards from the stove to the hood specified in the technical documentation must be observed.
How to determine the optimal distance from the stove to the hood
When arranging a kitchen space, special attention must be paid to the distance from the stove to the hood The state of clean air, free from soot and unnecessary odors, directly depends on the operation of the hood. That is why it is so important to choose it correctly and determine the correct distance from the hob to the device itself. A properly chosen height affects not only the overall efficiency of ventilation, but also ensures the safety of the system as a whole.
Optimal hood height above a gas stove according to the standard
The absence of a hood above the stove or its incorrect location can significantly complicate the process of cooking and create some discomfort while in the room. Proper installation of the exhaust device according to the standard will ensure the necessary air circulation and comfort for the housewife in the kitchen. At what distance from the stove should the hood hang?
It is best to place the hood above a gas stove, taking into account certain standards
- Gas stoves with direct hood should have a distance between each other of 75-85 cm;
- If the hood is inclined, then the gap between its lower part and the gas stove should be at least 55 and maximum 65 cm;
- An electric oven should have a distance of 65-75 cm to the direct hood;
- In the case of an inclined hood, a stove with electric burners can be located at a distance of 35-45 cm from its lower part.
This range was not chosen by chance and you cannot arbitrarily reduce the recommended minimum distance between the hood and the stove. True, you can still increase it a little if necessary.
Reducing the distance can make it more difficult for the cook, who may constantly hit his head on the device. In addition, the hood can become very hot, which jeopardizes its operation. That is why it is extremely undesirable to reduce the distance recommended by GOST.
When choosing the height of the hood above the stove, you should also consider:
- Power and design of the device;
- Configuration and interior of the room;
- The height of the person who spends the most time at the stove.
Weak hoods, as a rule, should be hung at a level not exceeding 75 cm from the stove, but powerful modern installations can be mounted higher, if necessary.
Typically, each hood is accompanied by instructions that detail all the recommended distances and installation parameters.
What affects the distance from the gas stove to the hood
When installing a hood, one of the most important factors that deserves attention is the maximum and minimum height of its location from the border of the hob. Usually, in order to understand at what distance the hood should be hung, you need to study the instructions. If it is not there, you must comply with some conditions for installing the device.
The distance from the stove to the bottom of the hood directly depends on:
- Convenience of cooking - this means that the person preparing food should have free access to all the pots on the stove and not hit his head on the hood;
- Safety - the distance should be such as to prevent spontaneous combustion of anything or deformation of the material (a safe distance is considered to be 65-70 cm);
- The ability of the device to extract air from the most contaminated layers - in other words, the extraction power.
The dimensions of the hood also matter. For example, the width of the device should not be less than the width of a gas or electric stove, otherwise it will not be able to clean the entire surface of the stove from contaminated air.
The type of hood also plays a role. Above an electric stove, a lower position of the hood is allowed than above a gas one, and it is also taken into account exactly how the device is located - with an angle or straight.
If the hood hangs at an angle, its lower edge usually drops slightly below the recommended distances. For a gas stove the gap is 55 cm, and for an electric stove it is 35 cm.
Standard installation of a hood over a gas stove and types of devices
A standard hood is a design that purifies the air from various fumes, gas combustion products, smoke, and various odors that appear during cooking.
According to the principle of operation, there are two types of hoods:
- Flow-through - remove air outside the room, but at the same time require a fresh supply of air from outside;
- Recirculation - purify the air on site, passing it through special filters and “returning” it to the kitchen.
Flow hoods work faster, but require a ventilation system, unlike recirculation hoods.
As a rule, its correct installation depends on the type of hood
Based on installation conditions, the hood can be:
- Wall-hung - as a rule, it has a flat appearance and is installed from the bottom of a wall cabinet above the hob;
- Dome - installed after placing the cabinets, can be decorated to suit a variety of styles;
- Built-in - its body is usually located inside the cabinet above the tile, the optimal height is determined according to recommended standards;
- Corner - may be needed where the stove is moved to the end of the wall and the kitchen hood has to be placed in the corner of the room;
- Wall-mounted (inclined) – mounted directly on the wall, the distance is measured from the slab to the bottom border of the hood;
- Island - this type can be found in large kitchens of catering establishments, where the hood is attached to the ceiling in the center of the room.
We should also talk about built-in exhaust devices. There are models that are embedded into the surface of the countertop, behind the stove. This type can also be called tabletop and in this case the gap between the stove, table and hood is reduced to almost a minimum.
There are also special glass-ceramic hobs with an induction cooking system and a built-in hood. This type of stove is very convenient to use, but, unfortunately, it is very expensive.
The hood can also be installed, choosing according to the design. This means that it can be stationary, removable or tilted, that is, introduced into the air purification zone when necessary.
Before hanging the hood, you must very carefully select the place where it will be located. All necessary communications or sewer outlets must be available.
You can hang the hood over a gas stove yourself if you carefully read the step-by-step instructions
For successful subsequent operation of the device, the following rules must be observed when installing it:
- The size of the hood must correspond to the size of the stove itself in order to have access to all contaminated layers of air;
- The distance from the device to the stove should not contradict fire safety measures and the type of stove (the norm is usually indicated in the technical data sheet of the hood);
- The socket used to connect the hood to power should not be located above the tile;
- The air exhaust pipe must have a minimum number of bends.
When connecting the hood, you should also install a special protective unit in the power supply of the device, which can turn off the equipment in the event of an emergency.
What should be the distance from the stove to the hood (video)
Buying a range hood is a responsible matter, because the convenience of cooking and a comfortable stay in the kitchen in general depends on the operation of this device. It is best to entrust the installation of this equipment to specialists so that they can efficiently connect all the necessary communications and provide everything necessary for the successful operation of the hood.
The ventilation ducts located in the building do not always cope with the problem of exhaust air. Often, they are ineffective. A way out of this situation may be to have an exhaust system.
When starting installation, the question arises: what should be the distance from the stove to the hood and what kind of hood should you hang in your kitchen? This question is very relevant. The quality of its operation 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, vapors, soot, odors, gas combustion residues and other harmful components outside the building or purify the air and then return it inside the kitchen. The level of purification of a room from dirty air depends on the height at which the hood is hung and how the air will be purified.
Depending on where the taken air goes, the method of cleaning it is determined. It can be flow-through 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 involves drawing in dirty air and removing it through the building’s ventilation system to the outside. The positive side of this method is the maximum and quick cleaning of the kitchen from harmful air. To get fresh air, just open a window or vent.
The circulation method is based on sucking and pumping dirty air through a system of carbon filters, followed by its release inside the kitchen. This method does not require the installation of ventilation ducts. A significant disadvantage is the long time it takes to clean the air and the rapid wear of the filters.
Types 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:
- Hanging. They have a flat shape. The installation location can be the bottom of a wall cabinet or shelf.
- Built-in. This type is mounted instead of the bottom of a wall cabinet. Often the cabinet itself serves as a housing that hides the exhaust system and its communications.
- Wall-mounted. Installation is carried out above the slab, like a suspended exhaust system. But the system body is mounted on the wall.
- Angular. Installation of such devices is carried out above the stoves, which are located in the corner of the kitchen. They can do angular shapes.
- Island. Used in large kitchen areas. Mounted on the ceiling in the center of the kitchen.
The distance from the gas stove to the hood is an important factor on which the efficiency of the equipment and the cleanliness of the air in the kitchen depend. Let's look at what this parameter depends on and how the characteristics of the device influence it.
Features of kitchen exhaust equipment
Before you understand at what height to hang the hood, you need to study the design features and operating principle of the device. At its core, a kitchen hood is a design that is designed to forcibly remove gas combustion products and other harmful impurities. The device consists of a housing, an air intake, electrical ventilation parts and a set of filters.
According to their operating principle, hoods are divided into 2 types: flow and circulation. The operation of the first type of equipment is based on the removal of dirty air into the ventilation pipes of a residential building. In this case, it is possible to achieve almost complete air purification, but such a system requires a regular influx of clean air masses from outside.
The second type does not extract air from the kitchen, but filters it through a set of filters built into the system. The main advantages of this equipment include the absence of unnecessary lines. Among the disadvantages are the large amount of time spent on high-quality cleaning.
What types of hoods are there based on installation method?
All hoods available on the market lend themselves to a certain classification. It depends on the method of installation of the equipment. Thus, devices for air purification in the kitchen are divided into:
- hanging;
- built-in;
- wall;
- corner;
- island.
Systems of the first type have a flat shape and are mounted under the shelf of a wall kitchen cabinet located above the stove. The second type is hoods, the design of which is built into a dome or cabinet above the stove. Wall-mounted hardware is installed on the wall above the stove. Corner type equipment is used for installation in the corner of the kitchen. Such systems are especially convenient if the slab is located closer to the end of the wall. The latter type of equipment is very relevant for large kitchens, where the hood should be installed in the center.
Depending on the shape of the air intake, there are four main types of hoods: vertical, horizontal, flat and domed. Flat systems have a bottom surface that resembles rectangular blinds. Sometimes there are low sides on the sides of the surface. They are installed above the stove in a horizontal position. The width of models of such equipment can be 50 and 70 cm. Vertical systems are equipped with a lower surface located at an angle. A guide visor is installed in the upper part.
Dome systems are considered the most popular. In shape they resemble a tent, the width of which can range from 50 to 120 cm. The height of the dome itself in most cases is 30–50 cm.
What parameters to consider during installation?
The main factor when installing the system is the height of the hood above the gas stove. Before hanging the equipment, you need to decide on the distance at which it will be installed. In most cases, the installation height of the hood is indicated by the manufacturer in the operating instructions. However, if this recommendation is absent, then the distance can only be determined taking into account certain conditions.
The first of these is safety. It determines the minimum permissible distance between open fire and the bottom plastic panel of the hood, at which the equipment will not ignite. The minimum height will be 60–70 cm.
The second factor is determined by the convenience of cooking. A housewife who spends a lot of time in the kitchen and uses household appliances must independently determine the optimal position of the hood, taking into account the convenient placement of tall pots on the stove.
The third factor is the system’s ability to draw contaminated air from the most inaccessible places on the stove.
Based on all these conditions, we can conclude that a distance of 70 cm is considered optimal. This result may vary depending on the height and size of the person who spends the most time at the stove.
How equipment parameters affect height
The calculation of the distance between the stove and the hood is influenced by the area of the air intake, the type of its location and the power of the equipment. Low-power systems must be suspended at a height of at least 75 cm. More powerful devices capable of processing more than 550 cubic meters per hour allow you to increase the distance.
Another important parameter is the size of the system. Its width should not be less than the slab itself. In this case, it will not be able to completely cover the surface that pollutes the air. The average width of the slab is in the range of 50–60 cm. Therefore, hoods with dimensions of 65–70 cm cannot be installed too high above such slabs. Only a system with a width of at least 80 cm can be hung higher.
The position of the air intake also affects the height above the stove. If it is placed at an angle, then the system must be installed so that its lower surface is located at a distance of 60 cm from the stove.
When installing equipment, pay attention to the fact that the materials from which it is made are practically incapable of igniting. Only stains of fats and other substances accumulated on the surface can catch fire.
Using a stove is accompanied by the process of gas combustion and the release of residual products into the surrounding space. Owners need to know exactly the optimal distance from the stove to the hood, which will be sufficient to ensure high-quality air exchange. You cannot do without an exhaust unit for the kitchen. But the question is more relevant than ever.
This parameter determines the efficiency of the device, as well as the cleanliness of the air in the kitchen. The latter is especially important in conditions where the kitchen is combined with the dining room.
Distance from the stove and inclined and horizontal hood
The installation height above the stove is determined by two criteria - the type of stove and the placement of the unit.
The design features of the household appliance, the size of the air duct or the presence of additional elements do not affect this value. An exception to the rule is situations where the ceiling is at a low height and the distance from the stove to the hood cannot be structurally maintained. Experts advise taking into account the rated power of the device, and then adjusting the height ±10 cm from the recommended average.
Inclined hoods
When installing inclined models of devices, the distance specified by the manufacturers should be observed:
- from 35 to 50 cm, if dishes are planned to be cooked on an electric or induction hob;
- from 55 to 65 cm is the recommended distance to the hood above the gas stove.
It is worth mounting a kitchen appliance where it will be convenient to use. Naturally, the values indicated by experts are not taken “from the head”. The calculated data takes into account a number of criteria:
- room layout;
- kitchen area;
- the height of the hostess;
- power of the exhaust unit;
- interior and room features.
Professionals emphasize that the distance from the hob to the household unit can be increased if there is sufficient power reserve. As for lowering below the recommended value, this is strictly prohibited. Proper installation will complicate the operation of the device and make it inconvenient.
If the distance between the hood and the hob is below the recommended value, the unit will be subject to constant and significant heating. It is better to avoid such situations initially, otherwise the equipment will quickly fail.
Horizontal devices
At what height to hang above the hob depends primarily on the characteristics of the stove itself with a horizontal surface.
The placement of this type of equipment depends on several factors, the main ones being the type of stove, model, and technical characteristics of the device. Recommended values:
- for an electric stove - from 60 to 80 cm;
- for gas burners - from 65 to 85 cm.
The nuances of installation above an electric stove
For a kitchen, an exhaust device is a structure through which forced air exchange is carried out in the room. It sucks in polluted air, purifies it, eliminating small particles of fat, evaporation, combustion products, odors and even impurities that are formed during cooking.
The height of the hood depends on the design features of the installation itself. Here it is necessary to focus on several aspects:
- a flat-type suspended structure can be placed above a gas or electric stove in a horizontal position;
- Most often, a kitchen hood is mounted on the wall near the stove, and you can choose any height at the owner’s discretion;
- built-in devices are installed in a special kitchen unit located above the stove;
- For installation of an island unit, spacious rooms are best suited, where you can hang the hood in the central part of the room, near the ceiling.
The distance between the inlet and the exhaust must be at least 60 cm. Despite the fact that this value is not final and can be adjusted in each specific case, experts recommend sticking to it.
The distance from the stove to the hood is indicated not only by manufacturers of household appliances, but also by recommendations of specialists based on many years of use of various types and models. The question of what is the norm for installing a kitchen hood over gas heaters deserves special attention, since they are the ones that predominate in domestic houses and apartments.
Manufacturers of kitchen units in the instructions for each appliance recommend that consumers adhere to the installation conditions, as well as maintain the minimum distance between the hob and the hood. Here are just a few examples:
- The Russian company Saturn, in the instructions for the M60 model, indicates that the device should be mounted at a distance of 65 cm from the burner. The productivity of this model is stated at 245 m3/h.
- The Bosch DWW09W650 model is installed at a height of at least 65 cm above the gas burners. Above the electric stove - the distance from the hob can be reduced to 55 cm. The productivity of the device is 650,650 m3/h.
- The unit from Shindo Metida60W boasts a productivity of 420 m3/h. This model should be installed at a distance of 75 cm.
At what distance is it better to hang a kitchen unit? The distance between the bottom of the hood and the burners depends on 3 requirements:
- reduce the likelihood of spontaneous combustion;
- ensure the removal of contaminated air flows;
- guarantee comfortable use for the owner.
There are no horizontal restrictions; as for the vertical plane, the distance is within 70-90 cm.
Experts recommend checking with a company consultant at what height to install the hood, indicating the exact value, in order to optimize the functionality of the device. Sometimes the distance is increased by purchasing a powerful device, which will provide the owner with additional convenience.
Properly selected distance from the stove to the hood and professional installation will ensure efficient and long-term operation of the equipment. Carefully study the instructions, where the corresponding values and heights are indicated by the manufacturer.
