INSTALLATION
A) Wooden Joist Installation
- Install fan housing between ceiling joists using sufficient length of
screws as shown in Fig. 1 with the fan O/L facing the desired
exhaust duct direction.
- Install fan mounting brackets as shown in Fig. 2 to the fan sides
that are not connected to the joists.
- If the brackets are too short to reach the joist, use bracket
extensions
- Connect the circular duct to the backdraft damper. Secure with
duct tape and make sure there is no air leakage.
- Do not use power supply wires smaller than 14 AWG.

- Choose best location (next to ceiling joist)
