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
1 - Damper Assembly (attached)
2 - Mounting Brackets (attached)
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,
the radius of each elbow be as large as possible for the installation, and that insulated
hard ducting be used. This fan will require at least 12" of clearance in the ceiling or wall,
and will mount through drywall up to ½" thick. The fan mounts between 24" on center
joists using the provided mounting brackets.
3.
No additional vibration deadening materials are needed for this fan.
SECTION 2
Mounting to a Joist
1.
If the mounting brackets are not already in place, install both brackets through the top
set of slots on the fan housing and secure in place with the four included nuts as shown.
Center the fan housing between the joists and secure the mounting brackets with screws
(not included) to the joist. Adjust the height of the housing so that it will be flush with the
finished ceiling by loosening the mounting bracket nuts and sliding the housing up or
down on the bracket. Full tighten all four nuts to secure the housing in place (Figure 1).
Figure 1
SECTION 3
Existing Construction
1.
Install two - 2 x 4 headers (not included) between the joists (Figure 2). Install the
mounting brackets through the top set of slots on the fan housing and secure in place
with the four included nuts. Position the fan housing between the headers and secure
the mounting brackets with screws (not included) to the header. Adjust the height of the
housing so that it is flush with the finished ceiling by loosening the mounting bracket
nuts and sliding the housing up or down on the bracket. Fully tighten all four nuts to
secure the housing in place (Figure 3).

SECTION 5
Converting discharge
1.
To convert unit from right angle discharge to horizontal/vertical discharge, remove
screws holding the side access panel and duct adapter panel in place. Switch the
side access panel location with the duct adapter panel (Figure 5). In the right angle
configuration the air will enter the unit and flow out the side at a 90° angle. In the
horizontal/vertical discharge configuration, the air will enter the unit and flow directly
out the other side.

SECTION 6
Ducting

appropriately rated tape. Use screws or suitable clamps to secure in place. Do not allow
screws to interfere with operation of damper. Always duct the fan to the outside through
a wall or roof cap. It is recommended that low restriction termination fittings be used.
