WARNING

TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO

1. Use this unit only in the manner intended by the manufacturer. If
you have questions, contact the manufacturer at the address or
telephone number listed in the warranty.

2. Before servicing or cleaning unit, switch power off at service panel

3. Installation work and electrical wiring must be done by a qualified
person(s) in accordance with all applicable codes and standards,
including fire-rated construction codes and standards.

4. Sufficient air is needed for proper combustion and exhausting of
gases through the flue (chimney) of fuel burning equipment 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.

5. When cutting or drilling into wall or ceiling, do not damage electrical
wiring and other hidden utilities.

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.
