Installing a kitchen extractor fan, also called an over-the-range hood, will take fumes, exhaust and vapor from your kitchen oven or range and remove it from the home via duct work. These extractor fans usually have built-in lighting to help illuminate your working area. Installing a fan is a DIY project that most homeowners can complete without the assistance of a general contractor. However, keep in mind that installing one does require permanent modification to your home, as you need to cut into the walls to complete the installation.
Slide the vent cap onto the end of the vent hose, and secure the cap to the hose with the supplied fasteners and a screwdriver. In most cases, the fastener is a band clamp.
Center the mounting bracket for the hood over the range and on the wooden framing. Secure the bracket to the wood framing, using wood screws and a screwdriver.
Secure the electrical plate to the top of the range, using the supplied screws and a screwdriver. Once the plate is installed, plug the electrical cord of the hood into a grounded 110-volt electrical outlet.
