If a modern gas stove "lives" in your kitchen, then it is not recommended to do without a special extract over it:
- firstly, the gas that you use for cooking, during combustion, emits a fairly large amount of various substances that do not bring any benefit to the human body;
- secondly, all these products of combustion, if they are not purposefully forced to quickly assemble over your stove and go to the ventilation system, have time to disperse throughout the kitchen (before you get into the natural ventilation system) ;
- third, no matter how small the particles of gas burning products are, they, if you do not have an exhaust hood installed above the gas stove, have time to cover all your kitchen furniture with a thin layer, which does not contribute to its longevity .
Therefore, realizing that you can not do without a hood, you should not only think about how to choose it, but also how to hang the hood over the stove.
Gas stove residence
Ideally, your gas stove in the kitchen should be located directly under the ventilation grill. However, modern architects, knowing that most of the housewives in new homes will definitely buy themselves a hood, do not pay much attention to this moment. As a result, even in the kitchen of an expensive new building the stove (along with a gas pipe) may be in the opposite corner from the hood. What to do in this case?
There are two solutions to this problem:
- Move the gas pipe close to the ventilation grill. Unfortunately, you do not have the right to do this yourself. You will have to contact the local Gorgaz, order a project to transfer the gas pipe and gas valves from them. After that, their workers will come and the project will transfer the pipes to you. It is clear that with such a bureaucratic approach, this process will take too much time and will bring very tangible costs.
- Assemble the long air duct from the corresponding elements. In the event that the air duct, in your opinion, spoils the appearance of the kitchen, it can be hidden in a box of PVC panels, OSB, drywall or other similar materials.
Choosing a hood
Usually, most housewives choose hoods for their gas stove based on their financial capabilities. However, this approach is not always justified, since cheaper models are less powerful and are not always able to cope with the required amount of work (that is, they do not provide adequate ventilation of the kitchen).
It should not be forgotten that even a high-quality and powerful hood will not do its job 100% if there is no fresh air in the kitchen (for example, the window leaf will not be slightly open). Earlier, when the premises were wooden windows with cracks, from which every housewife dreamed of getting rid of, the problem of air flow from the street was solved by itself. Now, plastic windows deprive us of this “privilege”, unless they have a ventilation valve installed.
The exhaust width must necessarily be either greater or equal to the width of the gas stove, since it is necessary to hang the hood over the cooker in such a way that it draws in itself the products of gas burning, and smells and vapors.
Install the hood over the stove
A detailed instruction is always attached to any hood for a gas stove, which explains how to hang a particular hood model. However, there are general requirements:
- the hood must be located exactly in the middle of the plate (that is, the central axis of the hood width must coincide with the axis of the plate width);
- the distance between the hood and the stove is recommended to be equal to 70 centimeters;
- a separate electrical outlet must be equipped for the hood (in this case it is not recommended to use an extension cord);
- at the same time the electrical outlet should be positioned in such a way as to avoid bending of the drawing wire;
- any hood is always attached to the wall and never hangs on the ventilation box.
Fasteners for hoods are usually included.
After you have fixed the hood in its place, you can proceed to the assembly of ducts, while respecting the basic principles:
- the diameter of the duct should not be reduced throughout its length (that is, if the hood has an outlet of 125 mm in diameter, it is not recommended to attach a duct with a diameter of 100 mm to it);
- ducts are allowed to bend under 45 and 90 degrees, but it is recommended to do it only if you have purchased a fairly powerful hood;
- To prevent air movement from the ventilation shaft to the hood, install an anti-return valve on the air duct.
