INSTALLATION INSTRUCTIONS

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.

installed in a GFI protected branch circuit.

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.

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 number of elbows.

3. Use optional NuTone ducting accessories as needed.

IMPORTANT:

Use wire suitable for 90°C.

Plan to run 120vAC house wiring (with ground) from power source,

through wall switches, to junction box in fan. For separate control of
fan, light, and night light three wall switches are required. See
NuTone Catalog for accessory switches. For separate control of fan,
light, and night light, five conductors are needed between the wall
switch box and the fan's junction box.
