Typical 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. 4-inch round rigid metal duct is recommended for best performance.

Check that the plug-in connections for the Motor Control, Motor, and Speed Selection Switch are seated firmly in place.
-
Check that the Blower Wheel spins freely.
Symptom: The fan runs erratically. -
Check that the Blower Wheel is firmly attached to the Motor shaft and both spin freely.

- Check that the back draft damper in the fan’s Duct Connector pivots freely. Screws used to attach the ducting to the Duct Connector may be preventing the damper from opening.
- Check that the back draft damper in the wall or roof cap pivots freely. These dampers are sometimes mistakenly painted shut or obstructed by bird and insect debris.
