INSTALLATION INSTRUCTIONS
careful not to cut or damage any electrical or other hidden utilities. Install
the side rails on the housing and position the housing in the previously
cut hole so that it is flush with the finished ceiling. Secure the ends of the

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
1 - Damper Assembly (attached)
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 8" of clearance in the ceiling or
wall, and will mount through drywall up to
3/4" thick. The fan mounts between 16" or
24" on center joists using the 4 provided
mounting rails.
3. Select the most convenient electrical
knockout and remove using a straightblade screw driver (Figure 1).
SECTION 2
New Construction
1. Install the side rails on the housing and position the housing next to the
joist. 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 2).
