ASSEMBLY INSTRUCTIONS
4. 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 (1-3 feet) section of insulat-
ed flexible duct will ensure quiet operation.
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.
CONNECT ELECTRICAL WIRING
Run 120 V AC house wiring to the location of the fan. Use only UL-approved connectors (not included) to attach the house wiring to the
wiring plate. Refer to the wiring diagram, and connect the wires as shown.
