oriented correctly. See figure 12.

of housing are enclosed. See figure 13.
CONNECTING THE DUCT

existing ducting is metal you will require a short flexible
duct connector . Rigid duct may need to be cut for proper
installation .
-
Position the fan housing assembly properly and secure
existing ducting to the fan's damper .
- If using a flexible duct connector or duct adapter, use
aluminum foil tape at each end to secure the connector or
adapter to the existing ducting and to the fan's damper . See
figure 14.
-
Ensure that the fan's damper is unobstructed and free to
swivel freely .
If you are replacing an existing fan then proceed to “Securing
the Fan to The Ceiling Joists – Finished Ceilings” section.
If this is a new installation and your ceiling is unfinished,
proceed to “Securing the Fan to The Ceiling Joists –
Unfinished Ceilings” section.
