2. Mounting Tab Installation: Using the gauge on the fan’s
housing, line up housing so that it will be flush with the
finished ceiling. Position the fan so that the tabs rest flat
against the joist and secure with four nails or screws (not
provided) to ensure proper installation (Figure 4).

Existing Construction
1. Side Rail Installation: Set housing in position between the
joist and trace an outline onto the ceiling material (Figure 5).
Set housing aside and cut opening, being 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 rails to the joists (Figure 3).

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
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.
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 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.
4. Select the most convenient
electrical knockout and remove
using a straight-blade screw driver
(Figure 2).
SECTION 2
New Construction
1. Side Rail Installation: 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 with
screws or nails (not included) to the joists and slide the
housing into the final position (Figure 3).
