IMPORTANT FACTS
Your gas furnace uses air from
outside the home
for combus­
tion and venting. It is not to be installed using in-house air.
Therefore, both pipes must terminate outside the structure.
These pipes must not be obstructed in any way.
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 mate­
rials, 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.
• A furnace installed in an attic or other insulated space must
be kept free and clear of insulating material. Examine the fur­
nace 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 wa­
ter. 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.
If the furnace is left unattended for an extended period of time,
have it checked periodically 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”
in this manual.
SAFETY CONSIDERATIONS
Installation and servicing of 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 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
A.
When you see this symbol on the furnace and in instruc­
tions or manuals, be alert to the potential for personal injury.
Understand the signal word—DANGER, WARNING, or CAU­
TION. These words are used with the safety-alert symbol.
DANGER identifies the most serious hazards which
will
result
in severe personal injury or death. WARNING signifies hazards
that
could
result in personal injury or death. CAUTION is used
to identify unsafe practices, which would result in minor per­
sonal injury or product and property damage.
STARTING YOUR FURNACE
Instead of a continuously burning pilot flame which wastes val­
uable energy, your furnace uses an automatic hot surface igni­
tion system to light the burners each time the thermostat turns
your furnace on.
Follow these important safeguards:
• Never attempt to light the burners manually with a match or
other source of flame.

• Read and follow the operating instructions on the furnace.
• If a suspected malfunction occurs with your gas control sys­
tem, such as the burners not lighting when they should, refer to
the shutdown procedures on the furnace or in the next section
to turn off your system, then call your dealer as soon as
possible.
WARNING:
If overheating occurs, or the gas valve fails
to shut off the gas supply, turn OFF the manual gas valve
. .(see Figure 7) to the furnace BEFORE turning OFF the
■ electrical supply. Failure to follow this warning could re-
•’sult in a fire or explosion, and personal injury or death.
NOTE:
The qualified installer or agency must use only factory-
authorized replacement parts, kits, and accessories when modi­
fying this product.
• 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:
