4. Mount to I-joist
Slide one hanger bar (long) into channel B
on the housing and adjust as
needed to fit between framing. Hold housing in place so that the housing
contacts the bottom of the joist
.
Screw housing to joist through the hole A
and hole B. Screw the hanger bar onto the other side of joist through the
hole (refer to the right diagram).
Screw hanger bar to housing with screw A.
5. INSTALL ROUND 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 tape (not
included), secure all the ductwork connections so that they are air tight.
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.

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.
