Distance from the plate to the hood: norms, rules and recommendations

In any modern kitchen there is a place for a ventilation device. The distance from the plate to the hood determines the effective operation of this structure.

Types of exhaust hoods and their purpose

The extract protects the kitchen space and furniture from contamination with the smallest particles of fat and soaking in a mixture of different smells. Nobody will be pleased to feel from the curtains or from the soft upholstery of the chairs an unpleasant odor that can also penetrate into other living rooms.

All devices are divided according to the principle of operation into:

• Circulating (with built-in filter);
• Extracts with air duct (connected to the ventilation system).

In the circulation 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 to install the duct, and the distance between the cooker and the hood should be small.

The second type of umbrella is characterized by better work, as the air is completely removed from the room. Installed in large rooms.

Types of exhaust devices:

1. With a flat surface - the most common and popular type of devices, characterized by compact dimensions. As a rule, they work autonomously, thanks to built-in filters. The incoming hot air is cleared of fumes / grease, then re-fed to the kitchen. These extracts require regular cleaning and replacement of filter elements.
2. Dome - also in great demand. However, unlike the first, the polluted air flows are completely discharged through the duct to the street. But there are models on the type of flat - with built-in filters.
3. With an inclined surface are subspecies of dome exhaust structures. Most often they are made of heat-resistant glass and, in addition to performing the basic functions, bear aesthetic beauty. Inclined umbrellas are convenient in operation, as they are far from the head, and in some models the slope of the middle part of the device can be adjusted.
4. Built-in wall cabinet - hide the air outlets.
5. Desktop - mounted directly into the hob itself.

Where should the hood be located?

When buying a hood with it, there is always an instruction for use in the kit, which indicates where and at what distance from the plate the device should be located. The exhaust system can be built into the cabinet, and can be located under it, the main thing is that its size coincides with the dimensions of the hob, and it hangs just above the plate. Also, before purchasing the hood, you need to consult with specialists about its capacity. For example, a small kitchen 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 optimum distance from the hob to the hood?

The distance from the cooker to the hood is determined by the established standard. If there is an electric stove in the kitchen, the exhaust hatch should be located at least 65-75 cm from it, and if the hood 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 vary 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 growth of the person who is most likely to be at the stove, and the overall interior of the kitchen.

What are the standards for installing the hatch?

These are the optimum parameters for the installation of the hood, which contribute to its efficient operation. Reduce or increase them is not recommended. With a high location of the device, its power of absorption of air can be missed, then smells along with fat drops will spread everywhere. A low installation of the hood can interfere with the cooking process. So it will not only be inconvenient to approach a gas / electric stove and put high pans, but there is a risk of heating the structure, its ignition and violation of paintwork.

Thus, the question of how much distance from the plate to the hood should be, you can answer unequivocally: 75-85 cm in the case of a gas stove, and 65-75 cm - over an electric stove.

Factors influencing the location of the exhaust structure

When buying and subsequently installing the hood, consider the following factors:

1. Type of hob. The distance between the hood and the gas stove or electric stove should be calculated?
2. The declared power of the device.
3. Design / interior of the kitchen.
4. Compliance with the installation regulations for the ventilation hatch specified in the data sheet.

Compliance with these installation and operation conditions of ventilation equipment will maximize the use of the device and protect the kitchen from unpleasant odor and fat.

Rules for installing ventilation equipment

Optimal operation of the device depends on the following factors and installation rules:

• The size of the air handling unit must match the dimensions of the hob. Then all hot, dirty airflow will be completely absorbed by the hood and taken out to 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 above the stove. The distance from the appliance to the cooker should not conflict with the fire safety standards and depends on the type of plate. The required distance from the plate to the hood must always be indicated in the product data sheet.
• Connecting the device to the network.
• Installation of air-exhaust pipes, if required by the design of the hood.

Installation of ventilation equipment is best entrusted to professionals. But those who are confident in their abilities, it will not be difficult to hang the device with their own hands.

Install the hood with a circulating type of work is not difficult. First you need to measure its height and mark the control points. Then drill holes in the wall for the fasteners. Next, the device is mounted to the wall or to wall-mounted cabinets using self-tapping screws and special hooks that come with the kit.

Hoods of another type of air purification are installed in the same way as circulating. Only here it is already necessary to attach the airway pipe to the umbrella body. The pipe can be plastic or made of foil.

At the end of the installation of equipment it is necessary to carry out a control check of its operation (mainly for the second type of models). If the hood is not functioning or is too noisy, it is worthwhile to check all the connections of the device with the ventilation pipes and their integrity.

Arrangement of air ducts

The air duct should not be with a lot of bends, as this will significantly complicate the withdrawal of polluted air. It is desirable that the pipes are short, straight and contain a small number of knees. The direction of the duct is changed in a place with a large bending radius. The diameter of the outlet pipe should correspond to the hole in the structure of the exhaust device. It is not recommended to narrow the holes on purpose and mount additional connectors between them. This makes it difficult to free air flow, respectively, creates a large load on the working motor of the hood. There may be excessive noise.

Most often, these structures are made of thick foil, and then masked with PVC boxes / plasterboard, so as not to disturb the interior of the room.

Where should the rosette be located?

The electrical outlet for connecting the exhaust hatch is usually set at a height of 2-2.5 m above the floor. Thus, it should be located above the hanging lockers for 10-20 cm. It is also moved to the left or to the right of the air duct by 15-20 cm.

Experts recommend the use of modern sockets with grounding, which, at high voltage surges, turn off and do not allow the engine to burn out.

Operating Tips

1. Keep the device clean and wipe it off dust and grease after each switch-on.
2. Do not turn off the device immediately after cooking, as the steam particles can spread around the kitchen faster than they are absorbed by the appliance. Therefore, you need to leave a few more minutes to stretch to draw all the evaporation.
3. Regularly replace carbon filters - at least 2 times a year.

Conclusion

In the article above, the types of ventilation devices were considered, at what distance from the plate to hang the hood, how to clean the air.

With a competent installation of the hood, the device will ensure clean air in the room and cleanliness of the surrounding interior. When choosing and purchasing an umbrella, it is necessary to take into account the compliance of its capacity with the cubature of the kitchen, the appearance, and also the methods of air purification: a complete withdrawal through the air duct or circulation of purified streams.

The main points for installing a particular model of the device and the distance from the plate to the hood are described in the instructions. The generally accepted norms for determining the installation height of the device are: 75 to 85 cm for gas stoves; From 65 to 75 cm for installation over electric stoves.
