DUCT*
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.
