Proper insulation around the fan to minimize building
heat loss and gain. 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 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.
Locate unit above (GFCI-protected circuit required)
or within 5 feet of the shower head.
Locate unit away from heating or cooling sources
which can affect humidity levels.
Do not locate near window. Unit may respond to the
