The ducting from this fan to the outside of building has a strong effect on
the airflow, 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.
