2.Using wood screws (not provided) loosely attach the housing to ceiling joist through the keyhole slots in mounting tabs.
3.Adjust housing so that it will be flush with the finished ceiling. For the grille to fit properly, the housing’s rim must not extend beyond finished ceiling surface.
4.When housing is properly adjusted, tighten screws in slots.
Mounting Using Hanger Bars
(hanger bars sold separately, order model HB4) Refer to Figure 3.
1.Insert hanger bars in slots provided in housing.
2.Locate fan housing between joists so that the bottom of the housing is even with the planned finished ceiling. Extend the hanger bars to the joists.
3.Use screws or nails (not provided) to secure hanger bars to ceiling joists.
INSTALLING DUCTWORK
1.Refer to Figure 2. Place duct collar over flanges at discharge opening of fan. Secure collar by snapping tabs into slots in flanges.
2.Run 4" round duct from outside to fan’s discharge opening.
3.Connect duct to fan’s duct collar.
WIRING
All wiring must comply with local codes and unit must be properly grounded.
1.Run 120vAC house wiring (with ground) from wall switch to fan location.
