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.
