2b. Extend the hanger bars to the width of the framing. Position the
ventilator with the hanger bar tabs wrapped around the bottom edge of
the framing, holding the ventilator in place.
Secure hanger bars to framing using one screw on each end of hanger bar.
Select a proper hole and secure the hanger bars together using flange
screws.
3. ATTACH DAMPER/DUCT CONNECTOR
Snap the damper/duct connector onto the fan housing. The connector
must be flush with the top of the housing, and the damper flap should
fall closed.
4. 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.
Install ceiling material to complete the ceiling construction. Then, cut around
the fan housing.
First insert the sensor plug into the plug base on the power box, and then
install the grille.
To attach the grille assembly to the fan housing, pinch the grille springs on
the sides of the grille assembly, and position the grille into the housing with
the grille springs in the appropriate slots. Push the grille assembly towards
the ceiling to secure.

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

RECEPTACLE
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.
