INSTALLATION INSTRUCTIONS

CAUTION:
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 Glass 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 can be mounted directly to the
joist using the mounting tabs on the side 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).

New Construction
1a. Mounting Rail Installation: Install the 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).

1b. 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

Existing Construction
1a. Mounting 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 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).

1b. Mounting Tab Installation: Position housing against the joist and trace an outline of the
housing onto the ceiling material (Figure 6). Set housing aside and cut opening, being
careful not to cut or damage any electrical or other hidden utilities. Place housing next
to the joist and insure that it is flush with the finished ceiling. Secure with four nails (not
provided) to ensure proper installation (Figure 4).
