The housing mounts
with four (4) screws
or nails. Screw or
nail housing to joist
through lowest holes
in each mounting
flange, then through
highest holes. NOTE:
Mounting to
I-JOIST
(shown) requires use of
SPACERS
(included) between the
highest hole of each mounting flange and the I-joist.

mounting instructions

The ducting
from this fan
to the outside
of the building
has a strong
effect on the
air flow, noise
and energy use
of the fan. Use
the shortest,
straightest duct
routing pos-
sible for best
performance,
and avoid in-
stalling 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 airflow.
