Before you begin
- Turn off the fan circuit at the breaker. Use a stable platform and suitable eye and dust protection.
- Measure the actual mount and fan before cutting. Check for wiring and framing; provide solid ceiling backing.
- Follow the fan manufacturer's support, ducting and wiring instructions. Have electrical work completed by a qualified person.
Installation Instructions
-
Measure the fan and adjust the inner opening if needed.
Trim all four edges as needed, leaving enough ledge to support the fan's flange. Keep the outer flange and plate slots intact.
-
Fasten the fan to the exhaust mount.
Seat the fan's flange on the inner ledge. Drill into the mount through the fan's existing corner holes, then secure with screws.
-
Lift the assembled fan and mount into the ceiling opening.
Support the assembly and check that the mount's outer flange sits flat against the ceiling.
-
Fasten the mount to ceiling framing.
Keep the assembly supported while securing the mount through its fixing points. Trial-fit the plate before finishing.
-
Mud over the outer flange.
Protect the fan, cover the flange and screw heads, then let dry.
-
Sand smooth, blending into the surrounding ceiling.
Repeat thin coats as needed, then remove the sanding dust.
-
Prime and paint the finished ceiling.
Keep paint off the fan and plate slots. Leave the airflow path clear.
-
Paint the plate to match the ceiling.
Apply thin coats and keep the rear fixing points clean. Let it dry fully.
-
Position the plate and slide it into place.
Align the gravity fasteners, then slide to engage. Support the plate until secure and keep the perimeter gap open.
Restore power and run the fan. Check that the plate stays secure and airflow is clear.
