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
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 straight-blade screw driver (Figure 1).
SECTION 2
New Construction
1. Install the rails into the mounting channel on the housing. Center the mounting channel in
the slots on the housing, then from inside the housing tighten the mounting channel screws
so the channel is securely in place. 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).
SECTION 3
Existing Construction
1. Set housing in position between the joist and trace an outline onto the ceiling material
(Figure 3). Set housing aside and cut opening, being careful not to cut or damage any
electrical or other hidden utilities. Install the rails into the mounting channel on the
housing. Center the mounting channel in the slots on the housing, then from inside
the housing tighten the mounting channel screws so the channel is securely in place.
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 2).

SECTION 4
Ducting
CAUTION: ALL DUCTING MUST COMPLY WITH LOCAL AND NATIONAL
BUILDING CODES.
1. Connect the ducting to the fan’s duct collar (Figure 4). Secure in place using tape or
screw clamp. Always duct the fan to the outside through a wall or roof cap.
SECTION 5
Wiring
CAUTION: MAKE SURE POWER IS SWITCHED OFF AT
SERVICE PANEL BEFORE STARTING INSTALLATION.
CAUTION: ALL ELECTRICAL CONNECTIONS MUST BE MADE
IN ACCORDANCE WITH LOCAL CODES, ORDINANCES, OR NATIONAL
ELECTRICAL CODE. IF YOU ARE UNFAMILIAR WITH METHODS OF INSTALLING ELECTRICAL
WIRING, SECURE THE SERVICES OF A QUALIFIED ELECTRICIAN.
NOTE: This unit includes a side access panel for wiring that does not require the removal of the
fan’s blower assembly. If you choose to wire the unit from the inside, you will need to remove
the blower assembly and internal wiring compartment. Both methods are equally effective.
1a. External Wire Compartment: Remove the wire compartment cover screw and place
cover in a secure place (Figure 5).
1b. Internal Wire Compartment: Remove the three screws holding the blower assembly in
place and lift assembly out of housing (Figure 6). Remove the wire compartment cover
screw and place the cover in a secure place (Figure 7).
