In any modern kitchen there is a place for a ventilation device. The distance from the stove to the hood determines the effective operation of this design.
Types of exhaust hoods and their purpose
The hood protects the kitchen space and furniture from contamination with the smallest particles of grease and impregnation with a mixture of various odors. No one will be pleased to smell an unpleasant smell from curtains or upholstered chairs, which, moreover, can penetrate into other living rooms.
All devices according to the principle of operation are divided into:
- circulation (with built-in filter);
- ducted hoods (connected to a ventilation system).
In circulating models, the air is cleaned with a carbon filter and returned to the kitchen. Such hoods are effective only in small rooms where there is no possibility of installing an air duct, and the distance between the stove and the hood should be small.
The second type of exhaust hoods is characterized by better performance, since the air is completely removed from the room. Installed in large rooms.
Types of exhaust devices:
- Flat surface is the mosta common and popular type of device, characterized by compact dimensions. As a rule, they work autonomously, thanks to the filters built inside. The incoming hot air is cleaned of burning / fat, then again fed into the kitchen. These hoods require regular cleaning and replacement of filter elements.
- Domed - also in great demand. However, unlike the first, polluted air flows are completely removed through the duct to the street. But there are flat-type models with built-in filters.
- With an inclined surface - these are subspecies of dome exhaust structures. Most often they are made of heat-resistant glass and, in addition to performing the main functions, they carry aesthetic beauty. Inclined umbrellas are convenient to use, as they are far from the head, and in some models, the inclination of the middle part of the device can be adjusted.
- Built into closet - conceals vent pipes.
- Desktop - mounted directly on the hob itself.
Where should the hood be located?
When buying a hood with it, the kit always comes with instructions for use, which indicates where and at what distance from the stove the device should be located. The exhaust structure can be built into the wall cabinet, or it canlocated under it, the main thing is that its size matches the size of the hob, and it hangs exactly above the stove. Also, even before purchasing the hood, you need to consult with experts about its power. For example, a small appliance is not suitable for a large kitchen space, and in a small kitchen there is no need to install a very powerful unit.
How to determine the optimal distance from the hob to the exhaust device?
The distance from the stove to the hood is determined by the established standard. If there is an electric stove in the kitchen, then the exhaust hatch should be located at least 65-75 cm from it, and if the hood is above the gas stove, the distance between them is 75-85 cm. In the case when the device has an inclined surface, the installation parameters change slightly:
- the distance from the gas stove to the hood is reduced to 55-65 cm;
- height above the electric hob is reduced to 35-45 cm.
You also need to take into account the height of the person who will be most of all at the stove, and the overall interior of the kitchen.
Why is it necessary to comply with the standards for installing a hatch?
These are the optimal parameters for mounting the hood, contributing to its efficient operation. It is not recommended to reduce or increase them. With a high location of the device, its air absorption capacity may not be enough, then odors, together with fat droplets, will quickly spread everywhere. Installing the hood low may interfere with the cooking process. So not only will it be inconvenient to approachgas / electric stove and high pans, but there is a risk of heating the structure, its ignition and damage to the paintwork.
Thus, the question of what distance from the stove to the hood should be can be answered unambiguously: 75-85 cm in the case of a gas stove, and 65-75 cm above an electric stove.
Factors affecting the location of the exhaust structure
When buying and subsequent installation of the hood, the following factors should be considered:
- Type of hob. The distance between the hood and the gas stove or electric stove needs to be calculated?
- The declared power of the device.
- Design/interior of a kitchen space.
- Compliance with the installation of the ventilation hatch specified in the data sheet.
Compliance with these conditions for the installation and operation of ventilation equipment will allow you to get the most out of the appliance and protect the kitchen from unpleasant odors and grease.
Rules for installing ventilation equipment
Optimal operation of the appliance depends on the following factors and installation rules:
- The size of the ventilation device must match the size of the hob. Then all the hot polluted air flow will be completely sucked up by the hood and taken out into the street or cleaned through the filter and fed back to the kitchen. The standard dimensions of the device are from 60 to 90 cm.
- Properly installed hood over the stove. The distance from the appliance to the stove must notcontrary to fire safety regulations and depends on the type of slab. The required distance from the stove to the hood is always indicated in the instrument's data sheet.
- Connecting the device to the network.
- Installation of exhaust pipes, if required by the design of the exhaust hood.
Installation of ventilation equipment is best left to professionals. But for those who are confident in their abilities, it will not be difficult to hang the device with their own hands.
Installing a hood with a circulation type of operation is not difficult. First you need to measure its height and mark it with control points. Then you should drill holes in the wall for the fasteners. Further, the device is mounted to the wall or wall cabinets using self-tapping screws and special hooks included in the kit.
Exhaust hoods of another type of air purification are installed in the same way as circulation hoods. Only here it is already necessary to attach the air pipe to the umbrella body. The pipe can be plastic or foil.
At the end of the installation of the equipment, it is necessary to conduct a control check of its operation (mainly for the second type of models). If the hood does not function or is too noisy, you should once again check all the connections of the device with the ventilation pipes, their integrity.
Arrangement of the air duct
The air duct should not be with a lot of bends, as this will significantly complicate the removal of polluted air. It is desirable that the pipes are short, straight and contain a small number of elbows. Changing the direction of the duct is carried outin a place with a large bend radius. The diameter of the outlet pipe must match the hole in the design of the exhaust device. It is not recommended to deliberately narrow the holes and mount additional connecting elements between them. This makes it difficult for the free flow of air, respectively, creates a large load on the operating engine of the hood. Excessive noise may occur.
Most often, these designs are made of thick foil, and then masked with PVC boxes / drywall, so as not to disturb the interior of the room.
Where should the outlet for the hood be located?
The electrical outlet for connecting the hatch is usually installed at a height of 2-2.5 m above the floor. Thus, it should be located 10-20 cm above the hanging cabinets. It is also shifted to the left or right of the duct by 15-20 cm.
Experts recommend using modern sockets with grounding, which turn off at high power surges and prevent the device's motor from burning out.
User Tips
- Maintain the cleanliness of the device and wipe it from dust and grease after each use.
- Do not turn off the appliance immediately after cooking, as steam particles can spread through the kitchen faster than the appliance can absorb them. Therefore, you need to leave the hood to work for a few more minutes so that it draws in all the fumes.
- Change carbon filters regularly - at least 2 times a year.
Conclusion
In the article above, the types of ventilation devices were considered, at what distance from the stove to hang the hood, methods of air purification.
With proper installation of the exhaust device, the device will provide clean air in the room and the cleanliness of the surrounding interior items. When choosing and buying an umbrella, it is necessary to take into account the correspondence of its power to the cubic capacity of the kitchen, its appearance, as well as the methods of air purification: complete exhaust through the air duct or circulation of purified streams.
The main points for installing a specific model of the device and the distance from the stove to the hood are described in the instructions. Generally accepted norms for determining the installation height of the device: from 75 to 85 cm for gas stoves; 65 to 75 cm for installation above electric stoves.
