An extractor fan in the kitchen is a great idea. Working in the same way as a bathroom extractor, it will get rid of the steam and the smells associated with cooking. However, to fit an extractor, you will need to have basic electricity and wiring knowledge, so unless you already have that, you should take a course before starting the project. Check out the local paper or Internet for a course near you.
Turn off the electricity at the mains.
Choose a spot for the fan. A good place would be near the stove, as long as that is on an outside wall.
Check that there are no obstructions like downpipes on the outside of the wall you want to put the extractor fan on. If there is an obstruction and it is something that you can move, do so; otherwise, choose another spot.
Go back inside the kitchen and use the cable finder to make sure there are no wires buried in the wall where you want to put the fan.
Use the template that came with the extractor fan kit and, on the inside wall, draw around it to mark the size of the hole you will need to make.
Mark the centre of that space and drill through to the outside wall. Drill a series of holes within the marked-out area and use the hammer and chisel on the outside wall and the drywall saw on the inside wall to make the size of hole you need.
The extractor fan kit will come with ducting that will take the steam to the outside. Put this through the hole you have made. Wear gloves to avoid cutting your hands on the aluminium ducting.
Fit the cap to the outside of the fan to stop water getting in.
Wire the fan up; the easiest way to do this is to run a spur from an existing socket. To do this, you will need to use a 30-amp junction box. Follow the wiring instructions that came with the kit very carefully to make sure you get it right.
Fit the extractor fan into the wall and attach the wires to the junction box. The junction box will need to be fitted to the wall.
Tighten the connections before turning the electricity back on and testing the fan.
Allow a day to complete the project.
Electrical work around the home should never be attempted unless you are confident about your ability to do the job.
