Ceiling

Opening (W)

Ceiling

Opening (H)

Proper insulation around the fan to minimize building
heat loss and gain. 4” circular duct is recommended
for installation. 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.
