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)
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.
4. Select the most convenient electrical
knockout and remove using a straight-
blade screw driver (Figure 2).

SECTION 2
New Construction
1. Using the gauge on the fan’s housing (Figure 3), line up housing
so that it will be flush with the finished ceiling or wall. Position
the fan so that the tabs rest flat against the joist or stud and secure
with four nails (not provided) to ensure proper installation.
SECTION 3
Existing Construction
1. Position housing against the joist or stud and trace an outline of the
housing onto the ceiling/wall material (Figure 4). 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 or stud and
insure that it is flush with the finished ceiling. Secure with four nails
(not provided) to ensure proper installation (Figure 3).
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 5). Secure in
place using tape or screw clamp. Always duct the fan to the
outside through a wall or roof cap.
NOTE: If damper detaches from unit, reattach by snapping the collar
back onto the unit. It is designed to only fit one way.
