CAUTION:
SERVICE PANEL BEFORE STARTING INSTALLATION.
WARNING:
OR USE GASOLINE OR OTHER FLAMMABLE VAPORS AND LIQUIDS IN
THE VICINITY OF THE HEATER.
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

4 - Mounting Rails

1 - Instruction/Safety Sheet
2. Remove the two hex nuts holding the light reflector in place. Keep the reflector and nuts
in the carton until needed so they do not get damaged or lost (Figure 1).
Figure 1
3. Remove the fan's venturi assembly, which is secured in place with one screw through the
venturi (Figure 2). Keep the venturi assembly and the grill in the carton until needed so
they do not get damaged or lost.

WARNING:
SHOWER STALL ENCLOSURE.
4. Choose the location for your unit. 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 7" of clearance in the ceiling, and will
mount through drywall up to 3/4" thick. The
fan mounts between 16" on center joists using
the 4 provided mounting rails.
5. Remove the electrical knockouts using a
straight-blade screw driver (Figure 3).
SECTION 2
New Construction
1. Install the rails on the housing and position the housing next to the joist. Line up housing
so 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 housing into final position (Figure 4).

(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 with screws or nails (not provided) to ensure proper installation (Figure 4).
