INSTALLATION INSTRUCTIONS
CAUTION:
MAKE SURE POWER IS SWITCHED OFF AT
SERVICE PANEL BEFORE STARTING INSTALLATION.
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 Light Lens
1 - Damper Assembly (attached)
2 - #8 Screws
2 - Lockwashers
4 - Mounting Rails
1 - Instruction/Safety Sheet
2. Remove the fan's venturi assembly, which is secured in place
with one screw through the venturi (Figure 1). This is a captive
screw and will stay installed in the venturi. Keep the venturi
assembly and the grill in the carton until needed so they do
not get damaged or lost.
Figure 1
3. 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 mounts between 16" or 24" on
center joists using the 4 provided
mounting rails.
4. Select the most convenient
electrical knockout and remove
using a straight-blade screw driver
(Figure 2).
SECTION 2
New Construction
1. Install the side rails on the 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 to the joists with screws or nails (not
included). Slide the housing into its final position (Figure 3).
