SAFETY CONSIDERATIONS
Recognize safety information. This is the safety-alert sym-
bol . When you see this symbol on the furnace and in
instructions or manuals, be alert to the potential for personal
injury.
Understand the signal words—DANGER, WARNING,
CAUTION, and NOTE. DANGER, WARNING and
CAUTION are used with the safety-alert symbol. DANGER
identifies the most serious hazards which
will
result in severe
personal injury or death. WARNING signifies hazards which
could
result in personal injury or death. CAUTION is used
to identify unsafe practices which
would
result in minor per-
sonal injury or product and prop-erty damage. NOTE is used
to highlight suggestions which
will
result in enhanced instal-
lation, reliability, or operation.
To minimize the possibility of serious personal injury, fire,
furnace damage, or improper operation;
carefully follow
these safety rules:
Your gas furnace uses air adjacent to the furnace for combus-
tion and vents to the outside. Do not enclose it in an airtight
room or seal it behind solid doors. It must have adequate air-
flow for efficient combustion and safe ventilation. The vent
pipe must terminate outside the structure and must not be
obstructed in any way.

• Keep the area around your furnace clear and free of com-
bustible materials, gasoline, and other flammable liquids and
vapors.
4
• Do not cover the furnace, store trash or debris near it, or
in any way block the flow of fresh air to the unit.
• Combustion air must be clean and uncontaminated with
chlorine or fluorine. These compounds are present in
many products around the home, such as: water softener
salts, laundry bleaches, detergents, adhesives, paints, var-
nishes, paint strippers, waxes, and plastics.
• Make sure the combustion air for your furnace does not
contain any of these compounds. During remodeling be sure
the combustion air is fresh and uncontaminated. If these
compounds are burned in your furnace, the heat exchangers
may deteriorate.
• A furnace installed in an attic or other insulated space
must be kept free and clear of insulating material. Examine
the furnace area when the furnace is installed or when
insulation is added. Some insulation materials may be
combustible.
This furnace contains SAFETY DEVICES which must be
MANUALLY RESET. If the furnace is left unattended for
an extended period of time, have it checked periodically for
proper operation. This precaution will prevent problems
associated with no heat, such as frozen water pipes, etc. See
“Before You Request a Service Call’’ section in this manual.
BEFORE STARTING YOUR FURNACE
Examine the furnace installation to determine that:
1. All flue gas carrying areas external to the furnace (i.e.
chimney, vent connector) are clear and free of obstruc-
tions.
2. The vent connector is in place, slopes upward and is phys-
ically sound without holes or excessive corrosion.
3. The return-air duct connection(s) is physically sound, is
sealed to the furnace casing, and terminates outside the
space containing the furnace.
4. The physical support of the furnace is sound without sag-
ging cracks, gaps, etc. around the base.
5. There are no obvious signs of deterioration of the furnace.
6. The pilot and burner flames are in good adjustment (by
comparison with pictorial sketches or drawings of the
main burner flame and, if applicable, the pilot burner
flame).

WARNING
Fire Hazard! Failure to keep insulation clear of
furnace could result in fire, personal injury/death
or property damage.
WARNING
Do not keep combustible materials, gasoline, and
other flammable liquids or vapors around your
furnace. Failure to follow this warning could result
in fire, personal injury/death or property damage.
WARNING
For proper and safe operation the furnace needs
air for combustion and ventilation. Do not block
or obstruct the openings on the furnace, air
openings to the area in which the furnace is in-
stalled, and the space around the furnace. Failure
to follow this warning could result in fire, personal
injury/death or property damage.
