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 draft. 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.
FOR BEST RESULTS
When installing the ventilator in a new construction site, install the
housing during the rough-in construction of the building. The power
unit and grille should be installed after the finished ceiling is in place.
To install the ventilator in an existing building, an accessible area
(attic or crawl space) is required from above the planned location.
