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.
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.
• Unit consists of the housing, power unit/blower assembly (motor, wheel
mounting plate, grille, reflector, lens and duct collar).
• WARNING: To reduce the risk of fire or electric shock, do not use
this fan with any solid-state speed control device.
• WARNING: To reduce the risk of shock, disconnect power before
servicing.
• Not for use in kitchens.
• Do not install in a ceiling insulated to a value greater than R-40.
• For installation in sloped ceilings up to 7/12 pitch.
• Ductwork must point up.
FOR BEST RESULTS
For new construction install the housing during the rough-in stage of
construction. The blower unit, light and grille should be installed after the
finished ceiling is in place.
To install the Exhaust Fan-Light in an existing finished building requires
an accessible area (attic or crawl space) above the planned location.
