SECTION 1
Preparing the Exhaust Fan
1. Unpack fan from the carton and confirm that all
pieces are present. In addition to the exhaust fan
you should have:
1 - Grill with Glass Light Lens
1 - Damper Assembly (attached)
2 - #8 Screws
2 - Lockwashers
4 - Mounting Rails
1 - Instruction/Safety Sheet
2. Choose the location for your fan. To ensure the best
air and sound performance, it is recommended that
the length of ducting and the number of elbows be

kept to a minimum, and that insulated hard ducting
be used. Larger duct sizes will reduce noise and
airflow restrictions. This fan will require at least 6"
of clearance in the ceiling or wall, and will mount
through drywall up to 3/4" thick. The fan can be
mounted directly to the joist using the mounting tabs
on the sides of the housing or between 16" on center
joists using the 4 provided
mounting rails.
SECTION 2
New Construction

housing and position the housing next to the joist.
Using the gauge on the fan's housing, line up housing
so that it will be flush with the finished ceiling. Secure
the ends of the rails with screws or nails (not
included) to the joists and slide the housing into the
final position (Figure 1).
