INJURY TO PERSONS, OBSERVE THE FOLLOWING:
A. Installation work and electrical wiring must be done by qualified person(s)
in accordance with all applicable codes and standards, including fire-rated
construction.
B. Sufficient air is needed for proper combustion and exhausting of gases
through the flue (chimney) of fuel burning equipment to prevent back
drafting. 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.
C. When cutting or drilling into wall or ceiling, do not damage electrical wiring
and other hidden utilities.
D. Ducted fans must always be vented to the outdoors.

FOR BEST RESULTS
When installing the Exhaust Fan/Light in a new construction site, install
housing during the rough-in construction of the building. The blower unit,
reflector and grille should be installed after the finished ceiling is in place.
Refer to instructions on page 3 to install the Exhaust Fan/Light in an exist-
ing finished building.
PLANNING DUCTWORK AND WIRING
1. Use 4" round duct.
2. Plan duct run from discharge opening of fan to the outside. For best fan
performance, make duct run as short as possible and use minimum num-
ber of elbows.
3. Use optional NuTone ducting accessories as needed.
