In order to be able to “breathe deeply” in the kitchen, it is not enough to choose the ideal hood from a technical point of view, it must also be installed correctly. This is a rather complicated process, and you should not try to carry it out yourself, but it is still useful to know the main steps, if only to control the work of the installer team. Remember, no serious manufacturing company will take responsibility for the inefficient operation of the device if it is the result of illiterate installation. There are several technologies for installing hoods. ATIn this article we will consider one of the most common options— a wall-mounted air cleaner of a fireplace (dome) type, fixed above the hob.
one.Before proceeding with the installation of a kitchen air cleaner, it is necessary to conduct electricity to the place of its intended attachment. Make sure that the voltage in the mains corresponds to that for which the device is designed (usually a table with the technical characteristics of the device is located inside the fume hood). The hood must be switched on via a two-pole switch with a distance between contacts of at least 3mm. Install the outlet so that it is easily accessible. The socket must be grounded.
2.Before installing the air cleaner, it is necessary to make markings. Having drawn a line on the wall perpendicular to the working surface of the stove, mark the desired distance from the lower plane of the hood to the hob. It must be at least 65see. If the instructions for installing the hob provide for a greater distance (this may apply, for example, to modular «domino» systems that include deep fryers or a grill), this requirement must be observed.
3.Then, the distance from the lower plane of the hood to the mounting loops and the gap between them are measured, after which, by simple mathematical calculations, the place is determined where the screws for hanging the umbrella should be mounted. There may be two or four, depending on the model. Often, air cleaners are supplied with a special cardboard template, which greatly simplifies this work.
four.Having marked places for screws on the wall, they drill holes, insert dowels and screw in screws (as a rule, both are included in the kit). Dowels can be replaced with your own, while the diameters of the cap and the rod of the screws should be similar to those included in the kit.
5. An air duct hose (it can be made of either corrugated aluminum foil or smooth plastic) is connected to the exhaust hood nozzle. If their diameters do not match, the connection is made using a special adapter.
6. Before starting the installation of the device itself, to facilitate the work, remove the grease filters. Then hang the exhaust hood on the screws, making sure that they fit exactly into the hinges or holes.
7. Through the upper opening of the umbrella, the air duct hose is brought out, for which purpose a hole of the required diameter is first cut in the kitchen cabinet or furniture cornice. Later, an air duct is connected to the hose by means of an adapter.
8. Next, the air duct is mounted. It is laid from the grate of the ventilation shaft to the exhaust hood. Recommended duct diameter— at least 125mm, the narrowing of the pipe, if necessary, should be done only on straight sections.
9. Necessary bends of the duct are made with the help of special rotary elements (elbows). Pipes can be mounted hidden (behind a plasterboard structure, suspended ceiling) or open— on the wall, but most often they are simply laid on the upper plane of kitchen cabinets.
10. The last stage of installation— Connecting the chimney pipe to the vent. Its diameter should be 130-133mm. Remember that the hood must not be connected to chimneys through which the products of combustion of gas heating and water heaters are removed.
