•DO NOT: Enclose your furnace in an airtight room or seal
it behind solid doors.
•DO NOT: Keep combustible materials, gasoline, and other
flammable liquids or vapors around your furnace.
•DO NOT: Cover your furnace in any manner.
•DO NOT: Store anything (including trash or debris) near

•DO NOT: Use your furnace room as a broom closet or a
place to store any kind of chemical or cleaner.
•DO NOT: Contaminate the air used for combustion of your
furnace with any kind of chemical or fumes. This could
also cause heat exchangers, metal vent systems or compo-
nents to deteriorate.
NOTE:
These chemicals or fumes are present in many prod-
ucts around the home, such as: water softener salts, any type
of household cleaning product, any type of laundry product,
adhesives, paints, varnishes, paint strippers, waxes and
plastics, etc.
During remodeling be sure the combustion air is fresh and
uncontaminated. If these compounds are burned in your
furnace, the heat exchangers and metal vent system may
deteriorate.
NOTE:
The qualified installer or agency must use only
factory-authorized replacement parts, kits, and accessories
when modifying this product.
This furnace contains safety devices which must be manu-
ally reset. If the furnace is left unattended for an extended
period of time, have it checked periodically for proper oper-
ation. 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
obstructions.
2. The vent connector is in place, slopes upward and is
physically 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
sagging 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).
SAFETY CONSIDERATIONS
Installing and servicing heating equipment can be hazard-
ous due to gas and electrical components. Only trained and
qualified personnel should install, repair, or service heating
equipment.
Untrained personnel can perform basic maintenance func-
tions such as cleaning or replacing air filters. All other
operations must be performed by trained service person-
nel. Observe safety precautions in this manual, on tags, and
on labels attached to the furnace, and other safety precautions
that may apply.
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, and
CAUTION. These words are used with the safety-alert sym-
bol. 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 personal injury or product and prop-
erty damage. NOTE is used to highlight suggestions which
will result in enhanced installation, reliability or operation.
WARNING
Do not keep combustible materials, gasoline, and
other flammable liquids or vapors around your
furnace.
WARNING
Fire Hazard! Failure to keep insulation clear of fur-
nace could result in fire, personal injury, or death.
