The stove in your home is a heat generating machine, so the kitchen hood plays a vital role in the kitchen. The kitchen hood allows for dispersion of the stove's heat, along with an exit for smoke. If you've ever had a smoke alarm go off while you're cooking, you'll understand the importance of the kitchen hood. There are a few steps when installing a kitchen hood, along with a couple of options for venting the hood. The first step is ensuring you have measured the designated location and the hood to allow for proper space requirements.
Step 1 - Evaluate Ventilation
If you look under the kitchen hood you will see most hoods have an extra perforated box, the reason for this is that there are two main types of ventilation, the roof and the side of the house via the wall. Before you install a kitchen hood you will first need to know which type of ventilation you will be using. The top perforated square will need to be knocked out if you are using roof ventilation and the side square will need to be removed if using side ventilation.
If there is no existing ventilation, you will need to use a wet saw to cut out an accompanying hole in the tile and wood and run ducting to either a vent in the side of the house or the roof. A side vent will either be fastened with screws or with silicone, while the roof vent will be placed under the roof shingles and tarred into place, then a vent cap will be placed on top to prevent debris or rain from entering the vent.
Step 2 - Secure Wiring
In order to power the fan motor, you will need a power supply, which will be your house wiring. Drill a hole using an applicable drill bit, such as carbide-tipped or diamond-tipped, next to the previously removed vent hole and an accompanying hole in the tile to pull the wires through. A quick tip to drill through tile is to make an “X” with masking tape, ensuring not to lose your drilling point, to provide some surface friction. Once through, follow the wiring diagram provided with your kitchen hood to supply power to the fan, ensuring power is not going to the wires during installation to prevent electric shock.
Step 3 - Fasten
First you will need to clean the tile surface to ensure there will be no debris. Fastening in tile can be a little tricky, you will need to employ the same drilling method as above but you will also need wall anchors, that provide an unthreaded section where the tile will be. Using threads against the tile may damage the tile. After installing all of the anchors, you will proceed to caulk the corners of the kitchen hood to provide extra stability, with a kitchen caulk.
Step 4 - Operate
Once the hood is securely fastened and wiring is complete, resupply power to the fan motor. Turn the fan motor on and ensure it is spinning properly by visually inspecting it. Do not place your hands near the kitchen hood fan while power is being supplied to it.
