CAUTION is used to indicate unsafe practices which could
result in minor injury or property damage.
DO NOT use this furnace if any component was underwater.
Immediately call a qualified heating contractor to inspect
the furnace and replace any part of the furnace control
system that was underwater. This furnace does not have a
pilot light. It is equipped with an electronic ignition system
that automatically lights the burner.
The flow of combustion and ventilating air must not be
obstructed from reaching the furnace. Air openings provided
in the casing of the furnace must be kept free of obstructions
which would restrict airflow, thereby affecting efficiency and
safe operation of your furnace.
Also, air openings provided to the area in which the furnace
is installed and the space around the furnace shall not be
blocked or obstructed. Keep this in mind should you choose to
remodel the area which contains your furnace.
The furnace and venting system require a generous amount
of clean air to operate safely. Lack of adequate combustion
and ventilation air can result in erratic operation of the
burner, noisy and poor combustion, sooting of the combustion
chamber, and fuel odors in the air. Never block off or restrict
the supply of air to the furnace.
The combustion air for your furnace must be fresh unconta-
minated air. Paints, varnishes, laundry bleaches, detergents,
many household cleaners, water softening salts, adhesives, and
all such products release fumes containing compounds which
could lead to early heat exchanger and vent system deteriora-
tion. Do not store these types of products near your furnace.
Never store gasoline, combustible materials, or other
flammable liquids or vapors near your furnace.
TO PREVENT AN EXPLOSION OR POSSIBLE INJURY,
DEATH AND EQUIPMENT DAMAGE, DO NOT STORE
