IMPORTANT FACTS
Your furnace must have adequate airflow for efficient combus-
tion and safe ventilation. Do not enclose it in an airtight room or
“seal” it behind solid doors. To minimize the possibility of seri-
ous personal injury, fire, damage to your furnace, or improper
operation,
carefully follow these safety rules:
c
Keep the area around your furnace free of combustible
materials, gasoline, and other flammable liquids and vapors.
c
Do not cover the furnace, store trash or debris near it, or in any
way block the flow of fresh air to the unit.
c
Combustion air must be clean and uncontaminated with chlo-
rine or fluorine. 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 com-
bustion air is fresh and uncontaminated. If these compounds are
burned in your furnace, the heat exchangers and metal vent sys-
tem may deteriorate.

c
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 installing 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 inspect the fur-
nace 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 modi-
fying or repairing this product.
This furnace contains SAFETY DEVICES which must be
closed. 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 Ser-
vice Call” section in this manual.
SAFETY CONSIDERATIONS
Installing and servicing heating equipment can be hazardous due
to gas and electrical components. Only trained and qualified per-
sonnel should install, repair, or service heating equipment.
Untrained personnel can perform basic maintenance functions
such as cleaning and replacing air filters. All other operations
must be performed by trained service personnel. Observe safety
precautions in this manual, on tags, and labels attached to the
furnace 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 word—DANGER, WARNING, or
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 signi-
fies hazards that
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.
STARTING YOUR FURNACE
Your furnace is equipped with a continuously burning pilot
flame.
c
This manual ignition system requires the pilot to be match-lit
by hand.
c
Read and follow the operating instructions on the furnace,
especially the item that reads as follows:
c
Wait 5 minutes to clear out any gas. Then smell for gas, includ-
ing 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.
c
If a suspected malfunction occurs with your gas control system,
such as the pilot not lighting when it should, refer to the shutdown
procedures on the furnace or in the next section to turn off your
system, then call your service dealer as soon as possible.
c
CHECK AIR FILTER: Before attempting to start your furnace,
be sure the furnace filter is clean and in place. (See the mainte-
nance section of this manual.) Then proceed as follows:
STEPS FOR STARTING YOUR FURNACE
Refer to the lighting instruction label affixed to the furnace
blower access door.
1. Set your room thermostat to the lowest temperature setting.
(See Fig. 4.)
2. Close the external manual gas valve. (See Fig. 5.)
3. Turn OFF the electrical supply to your furnace.
(See Fig. 6.)
WARNING
Should overheating occur, or the gas valve fail to
shut off the gas supply, turn off the external man-
ual gas valve to the furnace BEFORE turning off
the electrical supply. (See Fig. 5.) A failure to fol-
low this warning could result in a fire or explosion,
and personal injury or death.
