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.
