Installing the unit
Installing the fan body in an existing building requires an accessible area (attic or crawl space) above
the planned installation location and existing duct and wiring.
CAUTION: Check area above installation location to ensure that:
• Duct work can be run and the area is sufficient for proper ventilation.
• Wiring can be run to the planned location.
• No wiring or other obstructions can interfere with installation.
WARNING:
• To reduce the risk of fire, do not store or use gasoline or other flammable vapors
and liquids in the vicinity of the heater.
1. Mounting the fan between the joists
a. Insert either the 12 in. suspension brackets (D) or
14 in. suspension brackets (E) to the duct side and
back of the fan body (C), depending on the distance
between the joists.
b. Insert the fan body (C) between joists. Make sure
the fan body is level and perpendicular with the
joist, and flush with ceiling surface.
c. Allow for thickness of the ceiling board
used in your application. Do not flush mount
to joist. Fan body (C) should be flush with ceiling
board.
d. Secure the suspension brackets to joists with the
long wood screws (CC).
e. Secure the suspension brackets to fan
body (C) with the short machine screws (AA).
