INSTALLATION
STEP 1. INSTALL HOUSING (Cont.)
B. INSTALLATION IN EXISTING CEILING OR
REPLACING AN EXISTING FAN
Existing ceiling: With a pencil, trace an outline of
the housing onto the ceiling. Set the housing aside
and cut out a 9-1/2” by 9-1/2” opening for the
fan. The cardboard protective cover can be used
as a template for the ceiling cut out. Position the
housing against the joist and make sure the bottom
edge of housing is flush with the bottom of the
joist. Leave ductwork and wiring in place. Proceed
to Mount Housing.
Replacing existing fan: Remove existing fan. Enlarge
ceiling opening to 9-1/2" x 9-1/2" if needed.
Fold the mounting ears flat
against the housing sides.
Position the housing against
the joist and make sure the
bottom edge of housing is flush
with the bottom of the joist.
Leave ductwork and wiring
in place. Proceed to Mount
Housing.
Mount Housing: The housing can be mounted directly to
the joist using the internal mounting holes or mounted
using the bottom flange.
I. Internal holes: Position the housing against the
joist and make sure the bottom edge of housing is
flush with the bottom of the joist. Using screws (A)
provided, attach the housing directly to the framing
or joist using the internal mounting holes in the
housing. Motor assembly must be removed to gain
access to the internal mounting holes.

II. Flange holes: Position the housing assembly
against the joist and make sure the bottom edge
of housing is flush with bottom of the joist. Use the
screws (A) provided to secure the housing to the
joist through the bottom flange holes.

STEP 2. CONNECT DUCTWORK
• Pull ducting through housing discharge opening. This
exhaust fan has a 4” exhaust damper. Connect house
ducting to the exhaust damper and seal all connections
with duct tape. Ensure that the exhaust damper flap
functions freely.
• Push exhaust damper back through opening, fixing the
exhaust damper by the tab. Run the ductwork to a roof
or wall cap.
NOTE: The ducting from this fan to the outside of
building has a strong effect on the air flow, noise and
energy use of the fan. Use the shortest, straightest
duct routing possible for best performance, and avoid
installing the fan with smaller ducts than recommended.
Insulation around the ducts can reduce energy loss and
inhibit mold growth. Fans installed with existing ducts
may not achieve their rated air flow.
