DANGER FROM
ASPHYXIATION
• Do not operate this furnace without
provisions for an adequate combus-
tion air supply.
• Do not allow snow, ice, or any other
debris to accumulate in or around the
exhaust and intake terminations of
this furnace. These are extended
through the roof or horizontally
through the sidewall of the structure.
See Figures 5 & 6. Blockage of the
intake and exhaust can result in inad-
equate combustion air as well as
inadequate unit performance or nui-
sance tripping.
• 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.
• Arrange your furniture and drapes so
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.
