This is a basic guide for fitting an extractor fan in your kitchen, bathroom, or laundry room. An extractor fan removes the odor, smoke and moisture in the area. You can buy it in two main types:
You can ask the extractor fan salesman about the pros and cons of each type. You may choose a centrifugal fan because of its more powerful action, for example.
Install the Extractor Fan
The following steps are general in nature. You can change them according to your own knowledge and skills.
Prepare the Work Area
Aside from the drill, bit, and bolts, you might need other tools as well. Before you start, make sure that you have a hammer, hammer drill, and adjustable wrench at hand. You never know when you might need to use them.
- Drill a reference hole on the ceiling as your mark. Use your power drill and a ¾-inch spade bit for it.
- Measure the vent fan housing with a tape measure and note the measurements on paper.
- Go up to the attic over the bathroom. Find the reference hole using a flashlight. Clear away the obstructions including the insulation around it.
- Use a copy of the cardboard template as a guide for clearing the area. Compare the cardboard measurements and vent house measurements just to be sure.
- Go back to your bathroom. Using a tape measure, get the measurements of the fan’s intake port.
- Mark the fan’s intake port outline on the ceiling by using its measurements. Use a pencil and framing square for the job.
Keep in mind the carpenter’s adage: Measure once, cut twice. You don’t want to cut out a too large or too small hole on the ceiling.
Cut the Hole
Be sure to cover the floor with old newspapers to protect it from falling debris.
- Use a jigsaw or drywall saw in cutting out the marked part on the ceiling.
- Support the rectangular piece from the ceiling with your free hand before lowering it to the floor.
This is where an assistant will be useful.
Place the Fan Into Position
- Attach a 90-degree duct elbow to the outlet port; use a foil duct tape.
- Place a cable connector through the knockout hole on the fan housing’s side. Slide its supporting metal brackets into their proper places.
- Center the fan over the hole before placing it into position. Check that the connected points are in proper orientation.
- Secure it to the joists. Use the metal brackets and drywall screws for this purpose.
- Attach the connections for the electrical cables and duct pipes.
- Test your new extractor fan.
Making the attachments for the extractor fan demands electrical and plumbing skills. You shouldn’t undertake this project unless you have mastered the basics in these areas. You can also refer to the instructions manual for the fan.
The installation of an extractor fan in the bathroom can be a DIY job. But you should have the right knowledge and skills for it. Otherwise, you will end up with a botched job.
When in doubt, you can always ask for a professional electrician to install the extractor fan. You may watch him as he does his work so that you can learn from him. You may then be able to replicate the steps in later projects.
