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.
