INSTALLATION INSTRUCTIONS
FOR BEST RESULTS
WARNING – TO REDUCE THE RISK OF FIRE, ELECTRIC
SHOCK, OR 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.
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.
PLANNING DUCTWORK AND WIRING
DUCTWORK
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 number of elbows.
3. Use optional NuTone ducting accessories as needed.
WIRING
D. Ducted fans must always be vented to the outdoors.
E. If this unit is to be installed over a tub or shower, it must be marked
as appropriate for the application.
F. NEVER place a switch where it can be reached from a tub or
shower.
Plan to run 120vAC house wiring (with ground) from power source,
through wall switch, to junction box in housing. For separate control of
fan and light use an optional NuTone switch.
IMPORTANT: Use wire suitable for 90oC.
