Assembling a hood is not as simple as it may seem. Although it does not include very complicated steps, it is important to take into account some essential details, such as the distance to the hob, the length of the escape route, the type of dowel you can use and other useful elements to be able to use it efficiently.
Have you just bought a new hood and are considering the option of mounting it without the help of a specialist? Before guiding you through the main steps involved in such a process, it is good to know that the correct installation significantly influences the performance of the device. So if you are not sure that you can handle it, carefully evaluate the offers of companies that can help you.
Prepare all the tools and materials you need
In order for everything to go well and to succeed in a correct assembly from the beginning, without the need for corrections, you need some important tools, to which are added the accessories of the product. In addition to the hood, you must also have at your disposal, either from the delivery package, or purchased separately: extensible aluminum tube, two metal clamps for tightening and anti-discharge flap.
The list of necessary tools includes: roulette, pencil and poloboc for the correct identification of the fixing points and the careful measurement of the space, the drill, the hammer, the screwdriver and a ladder that can take you safely to the height you will need to work. Avoid improvisations such as climbing on a chair or table, which present the risk of an accident.
Choose the right place for mounting
Use the ruler to identify the middle of the electric or gas hob and raise a perfectly vertical line from that point, drawing to the level to make sure you went up, exactly at a 90 degree angle. On this vertical draw a pencil mark at a height of 65 or 70cm, depending on the type of hob (65cm for electric models, 70cm for gas-powered ones). It is the safety distance necessary to protect the surface of the hood from heat, but also the level at which the device offers you the best operating efficiency, easily absorbing the vapors released during food preparation.
If you want to install a hood with exhaust pipes, you will need to install the pipe vertically in the axis of the hood. It is important not to use for this purpose pipes that are already allocated for another purpose (ventilation system, exhaust for a heating device, etc.).
We also know that you may be tempted to position the stove or hob further away from the outside wall, thinking that you can install a longer pipe that connects to the outlet. Our advice is to stay at the shortest route, not to exceed 5m, a too long length of the pipes affecting the efficiency with which the air is circulated to the external environment.
Carefully determine the points of support
Because, although similar, each hood model has different assembly details, the first step of this stage is always to consult the technical scheme included in the delivery package. You will find there exactly the distances you have to measure between the different elements that ensure the support of the hood on the wall.
Use the ruler, pencil and level to make sure you have accurately identified on the wall each point where you need to install a screwdriver. These details are very important to ensure the right mounting of the suction device, so do not rush, measure twice and mark once, as visibly as possible. The pencil is easily wiped from the wall.
Install the clamps first
It's time to use the drill to drill holes where you need to mount dowels. It is good to choose the latter carefully, depending on the type of wall you work with. If we are talking about solid materials, such as concrete, small brick (Clinker), natural stone or solid arch, you can use an expandable dowel.
For hollow bricks and vaults, simple or insulated cardboard gypsum board, alveolar gypsum board, etc. the screw dowel is recommended by beating. Although you will not often encounter these cases, it is good to know that if you want to install the hood on a friable material such as aerated concrete, porous concrete slabs, reconstituted stone or adobe, it is better to use beaten dowels, which do not require drilling in advance.
Depending on the model, you will have to install one or more clamps, or even none, if the hood is fixed directly by means of screws.
Attach the hood to the wall
Put the hood in place and, if it's heavy enough that you can't hold it alone, turn to a friend to help keep it straight. To complete the fixing you will need to remove the grille and filters to access the screws at the bottom of the clamps.
Use a camouflaged socket
If you want to have as few elements in sight in the kitchen as possible, which would affect the design, we recommend that you take care in advance of installing a socket that is camouflaged by the hood body. You will of course need the services of an installer for this part of the project and it is important to carefully fix the location, so as not to overlap with the area where you mount the hood.
Make sure you have a discharge valve
In order for the evacuation to always be efficient, you must start the assembly of the piping with the installation of the anti-discharge valve, which will be fixed with the help of a collar fastened in screws. Then unscrew the aluminum hose and connect it to the hood and the exhaust pipe. If you have opted for a hood without evacuation ( here is our comparative list ) , this step is one that will be cut from the list.
Carefully test the device
It is the moment when you attach the specific accessories to each version. You can have a telescopic housing that hides the piping, metal or glass edges and other decorative elements. Then replace the filters and grilles, plug in the device and test the operating speeds. Use the technical manual to make sure you are familiar with how to use it in the smallest detail, so that you can get the most out of the hood's performance.
