WARNING
THIS FURNACE OPERATES BY
BURNING GAS INSIDE YOUR
HOME. IMPROPER OR INCOM-
PLETE BURNING OF THIS GAS
CAN RESULT IN THE FORMA-
TION OF CARBON MONOXIDE. IF
INTRODUCED INTO THE LIVING
SPACE, THIS CAN CAUSE DIZZI-
NESS, NAUSEA, OR DEATH BY
ASPHYXIATION. YOU MUST
READ AND OBSERVE THE SAFE-
TY RULES BELOW TO PREVENT
OXYGEN DEPLETION OR

• Do not operate this furnace without
provisions for an adequate combus-
tion air supply.

debris to accumulate in or around the
exhaust and intake terminations of
this furnace. These are extended

• Prevent flue gases from escaping into
your residence. Deterioration of the
venting system, or soot build-up can
cause leaks into the system. Have a
qualified installer, service agency or the
gas supplier replace damaged parts or
repair obstructions in a deteriorated
vent system immediately.
• Do not use this furnace if any part has
been under water. A flood-damaged
furnace is extremely dangerous.
Attempts to use the furnace can result
in fire or explosion. A qualified service
agency should be contacted to inspect
the furnace and to replace all gas con-
trols, control system parts, electrical
parts that have been wet or the furnace,
if deemed necessary.
• To prevent carbon monoxide poisoning,
all blower doors and compartment cov-
ers must be replaced after the furnace
is serviced. Do not operate the unit
without all panels and doors securely in
place.
SYSTEM OPERATION
INFORMATION
• Keep the air filters clean. Your heating
system will operate more efficiently and
provide better heating, more economi-
cally.

that the supply air registers and return
air grilles are unobstructed.
• Close doors and windows. This will
reduce the heating load on your sys-
tem.
• Avoid excessive use of exhaust fans.
• Do not permit the heat generated by
television, lamps, or radios to influence
the thermostat operation.
• If you desire to operate your system
with constant air circulation, consult
your thermostat manual or please ask
advice from a qualified installer, service
agency or the gas supplier.
