IMPORTANT FACTS
Your furnace must have adequate
airflow for efficient combustion 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,
damage to your furnace, or improper
operation,
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 fluo-
carefully follow these
5
rine. These compounds are present
in many products around the home,
such as water softener salts, laundry
bleaches, detergents, adhesives,
paints, varnishes, 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 air with vapors
of these compounds is 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, electrical components and any gas control
which has been under water.
NOTE:
The qualified installer or
agency must use only factoryauthorized replacement parts, kits,
and accessories when servicing this
product.
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.
SAFETY
CONSIDERATIONS

equipment can be hazardous due
to gas and electrical components.Only
