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.
