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.
6. Ducted fans must always be vented to the outdoors.
7. Acceptable for use over a tub or shower (in the ceiling only)
when connected to a GFCI (Ground Fault Circuit Interrupter) -
protected branch circuit.
8. This unit must be grounded.

CAUTION
1. For general ventilating use only. Do not use to exhaust

CEILING INSTALLATION SHOWN
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, straighest 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.
4-inch round rigid metal duct is recommended for best performance.
