TYPES OF TYPICAL INSTALLATIONS

ASSEMBLY INSTRUCTIONS

1. Housing mounted to I-joists (Start at “ASSEMBLY INSTRUCTIONS 1”)

2. Housing mounted to joists (Start at “ASSEMBLY INSTRUCTIONS 1” )

3. Housing mounted to truss (Start at step “ASSEMBLY INSTRUCTIONS 2”)

1.MOUNT HOUSING TO JOIST OR I-JOIST.

Hold the housing so that it is in contact with the bottom of the joist.

Place the fan housing next to the ceiling joist. Using wood screws,

attach the housing loosely to the ceiling joist through the keyholes

in the mounting tabs. Adjust the housing to be flush with the finished

ceiling. For the grille to fit properly, the housing’s rim must not

extend beyond the finished ceiling surface. When the housing is

correctly adjusted, tighten the screws in the slots.

2. MOUNT WITH HANGER BARS

Insert the hanger bars into the slots in the housing. Place the fan

housing between the joists, make sure the bottom of the housing

is even with the finished ceiling. Extend the hanger hars to the

joist. Use screws to secure the hanger bars to the ceiling joists.

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.

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

For model PCV80

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.
