PLAN THE INSTALLATION
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 airflow.
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.
