to prevent backdrafting. Follow the heating equipment

manufacturer’s guideline and safety standards such as those

published by the National Fire Protection Association (NFPA),

and the American Society for Heating, Refrigeration and

Air Conditioning Engineers (ASHRAE), and the local code

authorities.

The ducting from this fan to the outside of the building has a strong effect on the air flow, noise and en-

ergy use of the fan. Use the shortest, straighest duct routing possible for best performance, and avoid

installing the fan with smaller ducts than recommended. Insulation around the ducts can reduce en-

ergy loss and inhibit mold growth. Fans installed with existing ducts may not achieve their rated airflow.

6-inch round rigid metal duct is recommended for best performance.
