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.
