Step by Step Instructions

1 Mark out the hole for your exhaust fan
2 Cut out the hole for your exhaust fan
3 Install the exhaust fan in the ceiling
  • Step 1. Mark out the hole for your exhaust fan

    When choosing a spot on the ceiling for your fan, get into your roof cavity and look for a gap in the joists that is clear of electrical wires. You should also clear any insulation away. Once you’ve found a good spot, tape the cardboard template in position on the ceiling and mark out your cutting circle.
  • Step 2. Cut out the hole for your exhaust fan

    Lay drop sheets down to protect your floor, fixtures and fittings. Then use your plaster saw to punch a small pilot hole inside the cutting circle you marked on the ceiling. Now, from inside the pilot hole, cut outwards and around the rim of the circle.
  • Step 3. Install the exhaust fan in the ceiling

    Put the fan in the hole, keeping the power cord on top of the motor where the electrician can reach it easily. Then hold the fan in place, while you tighten the screws on the rim. These screws engage small catches that grip onto the top of the plasterboard. Finish the job by pushing the cover plate into place.
