ASSEMBLY INSTRUCTIONS
2.Mount with mounting holes and hanger bar
Slide one hanger bar into the channel on the housing and adjust to fit
between framing. Hold housing in place so that the housing contacts the
bottom of the joist. Screw housing to joist through hole A and hole B.
Screw the hanger bar onto the other side of joist through the hole (refer
to diagram at right). Screw hanger bar to housing with screw A.

5. INSTALL DUCTWORK
Connect the round ductwork (not included) to the damper/duct connector,
and run the ductwork to a roof or wall cap (not included). Using duct tape
(not included), secure all the ductwork connections so that they are air tight
Insulated flexible duct is recommended for the quietest possible installation.
If rigid duct is used, a short (1-3 feet) section of insulated 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 120V 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.
