INSTALLATION: FAN & DUCT
Attach 4 lengths of the provided chain to the the attic’s rafters at four locations using wood screws (
NOT
provided
) screwed through a chain link. Alternatively, eye bolts (
also
NOT provided
) can be anchored into
the rafters and additional S-hooks (
also NOT provided
) used to attach the chain thereto
Attach the 4 provided S-hooks to 4 of the D-rings attached to the fan housing. Hang the fan assembly
from the rafters using these S-hooks and the 4 lengths of chain just installed as shown below in Figure 7.
When hanging the fan assembly, adhere to the following guidlines:
•
Do not hang the fan using fewer than 4 lengths of chains or eye bolts; all four attachment points are
necessary to support the fan’s weight and to eliminate any swaying motion.
•
Ensure that the fan is as level as possible.
•
Blocking this fan’s exhaust can cause it to fail prematurely. Keep the area in front of the fan as unob-
structed as possible: no object should be closer than 24” to the face of the fan.
Next, slide one end of the flexible ductwork over the backdraft damper’s collar and fasten it thereto using
4 of the 8 provided self-tapping sheet metal screws.
Then, gently bend the ductwork to a 90 ̊ angle and slide the free end over the fan assembly’s collar and
fasten it thereto using the remaining 4 provided self-tapping sheet metal screws.
Figure 8 at the top of the next page describes the two ductwork conntections. Adhere to the following
guidelines when attaching the ductwork to the backdraft damper and fan assembly:
•
Make sure to maintain the full diameter of the ductwork through the bend; this provides adequate
airflow and helps minimize noise.
• Avoid sharp bends in the ductwork or contact with metal fixtures, pipes, or conduits.
•
The section of ductwork immediately before the fan should be as straight as possible.
•
If necessary, the ductwork can be supported under the bend using extra chain wrapped with a protec-
tive material (e.g. carpet).
KEEP AIRSTREAM AS UNOBSTRUCTED
AS POSSIBLE
