IMPORTANT -
The ducting from this fan to the outside
of the building has a strong effect on the air fl ow, 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 fl ow.
Use a roof cap or wall cap that has a built-in damper to
reduce backdrafts.
Plan to supply the unit with proper line voltage and
appropriate power cable.
