IMPORTANT FACTS Your furnace must have adequate air-
flow 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;
carefully follow these safety rules:
• Keep the area around your furnace
free of combustible materials, gasoline,
and other flammable liquids and
vapors.
3
• 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-
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.
During remodeling be sure the com-
bustion air is fresh and uncontami-
nated. If these compounds are burned
in your furnace, the heat exchangers
and metal vent system may deteriorate.
• A furnace installed in the attic or
other insulated space must be kept free
and clear of the insulating material.
Examine the furnace area when install-
ing the furnace or adding more insula-
tion. 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 in-
spect 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 re-placement parts, kits,
and accessories when modifying or
repairing this product.
This furnace contains safety devices
which must be manually reset. If the fur-
nace is left unattended for an extended
period of time, have it checked periodi-
cally for proper operation. This precau-
tion 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 Installing and servicing heating equip-
ment can be hazardous due to gas and
electrical components. Only trained
and qualified personnel should install,
repair, or service heating equipment.
Untrained personnel can perform basic
maintenance functions such as clean-
ing and replacing air filters. All other
operations must be performed by
trained service personnel. Observe
safety precautions in this manual, on
tags, and on labels attached to the fur-
nace and other safety precautions that
may apply.
Recognize safety information: This is
the safety-alert symbol
. 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—DAN-
GER, WARNING, and CAUTION.
These words are used with the
safety-alert symbol. DANGER identi-
fies 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
property damage. NOTE is used to
highlight suggestions which will result
in enhanced installation, reliability or
operation.
STARTING YOUR FURNACE Your furnace uses an automatic hot sur-
face ignition system to light the burners
each time the thermostat signals the
furnace to start.
Follow these impor-
tant safeguards:
• Never attempt to manually light the
burners with a match or other source of
flame.

• Read and follow the operating in-
structions on the furnace, especially the
item that reads as follows:
“Wait 5 minutes to clear out any gas.
Then smell for gas, including near the
floor. If you smell gas,
STOP!
Follow
“B’’ in the safety information above on
this label. If you don’t smell gas, go to
the next step.”
• If a suspected malfunction occurs
with your gas control system, such as
the burners do not light when they
should, refer to the shutdown proce-
dures on the furnace, or in the next sec-
tion, to turn off your system, then call
your dealer as soon as possible.
•
CHECK AIR FILTER:
Before at-
tempting to start your furnace, be sure
the filter is clean and in place. (See the
maintenance section of this manual.)

Should overheating occur, or
the gas valve fail to shut off the
gas supply, turn off the manual
gas valve (See Fig. 6) to the fur-

follow this warning could re-
sult in a fire or explosion, and
personal injury or death.
