- 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.

duct tape and make sure there is no air leakage.
