Install Round Ductwork
a) Connect the round ductwork (not included) to the
damper / duct connector, and run the ductwork to a
roof or wall cap (not included)
b) Using tape (not included), secure all the ductwork
connections so that they are air tight
c) Insulated flexible duct is recommended for the
quietest possible installation. If rigid duct is used, a
short (1-3ft) section of insulated flexible duct will
ensure quiet operation

Install Duct and Blower Assembly
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 airflow.
Retrofit Installation
a) Mount with additional mounting holes:
The interior of the fan housing contains additional mounting
holes in case exterior mounting is not possible. Screw or nail
the fan housing directly to the framing or joists. Remove the
blower assembly as directed in the service parts section of
this manual's very last page to gain access to the additional
mounting holes
b) Mount with hole of the flange:
Use screws (included) to screw fans to the ceiling through
the holes of the housing
1. Remove wire panel and blower assembly before installation
2. Fold mounting hears flat against housing
3. Enlarge ceiling opening to 9-1/2" by 9-1/2", leave ductwork
and wiring in place
4. Connect wiring according to the wiring diagram on the next
page of this instruction manual. Re-install wire panel
5. Mounting fan

Connect Duct:
