Read All Instructions Thoroughly Before Beginning Installation

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. Switch power off at service panel and lock the service 

disconnecting means to prevent power from being switched on accidentally 

during installation.

B.  When cutting or drilling into wall or ceiling, do not damage electrical wiring 

and other hidden utilities.

C. Ducted fans must always be vented to the outdoors.

D. 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 local code authorities.

E.  ASHRAE residential ventilation standard 62.2 limits exhaust fans (total) to 

a maximum of 15 CFM per 100 square feet of occupiable space, unless a 

back drafting test is performed or make-up air is provided. Consult a local 

HVAC engineer for make-up air evaluation.
