Install A Bathroom Fan

Tools:

reciprocating saw
power drill
paddle bit
keyhole saw
caulking gun and caulk
pry bar
screwdriver
utility knife
folding ruler

Steps:

1. Turn off power leading to room at the breaker and remove existing fan. If necessary, trim away some of the wallboard using the utility knife to free the fan (figure A).

2. Measure casing for new fan and transfer the measurements to the wall (figure B). Cut out the opening for the new fan using the keyhole saw.

3. Take the drill with paddle bit and drill a hole through the exterior wall at each of the four corners of the opening (figure C).

4. Draw a line connecting each four corner on the exterior wall and use the reciprocating saw to cut an opening (figure D).

5. Slip the exterior fan shroud into position while a friend slides in the interior portion (figure E). Secure the exterior cover with screws (figure F) and run a bead of exterior-grade caulk around the cover.

6. Install fan unit on the inside, being sure to follow the manufacturer's instructions when making electrical connections.

7. Caulk around the edge of the fan unit on the inside.
