IMPORTANT FACTS

Your furnace must have adequate airflow for efficient com-
bustion and safe ventilation. Do not enclose it in an airtight
room or "seal'' it behind solid doors.
To minimize the possibility of serious personal injury, fire,
furnace damage, or improper operation; carefully follow
these safety rules:
• Keep the area around your furnace free of combustible
materials, gasoline, and other flammable liquids and vapors.
• 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 con-
tain any of these compounds. During remodeling be sure the
combustion air is fresh and uncontaminated. If these com-
pounds are burned in your furnace, the heat exchangers and
metal vent system 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 installing the furnace or adding more
insulation. Some materials may be combustible.
NOTE: Do not use this furnace if any part has been under
water. Immediately call a qualified service technician to
inspect the furnace and to replace any part of the control
system and any gas control which has been under water.
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.
