IMPORTANT - 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.
