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.
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.
G. For installation in sloped ceilings up to 12/12 pitch.
H. Ductwork must point up.
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.
MODEL: 8663RP, 8664RP
Suitable for use in shower or tub enclosure when used
with GFI protected branch circuit.
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 accesso-
ry 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. (Night
light not provided on 8664RP).
