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 
and must not be obstructed in any way.

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.
•  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.

 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 
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
 
Installing and servicing 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 func-
tions such as cleaning and replacing air filters. All other 
operations must be performed by trained service person-
nel. Observe safety precautions in this manual, on tags, and 
on labels attached to the furnace, and other safety precautions 
that may apply.
Recognize safety information. This is the safety-alert sym-
 
bol  . 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—DANGER, WARNING, and 
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
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 prop-
erty damage. NOTE is used to highlight suggestions which 
 
will
 
 result in enhanced installation, reliability or operation.
 
STARTING YOUR FURNACE
 
Instead of a continuously burning pilot flame which wastes 
valuable energy, your furnace uses an automatic, hot surface 
ignition system to light the burners each time the thermostat 
starts your furnace. 
 
Follow these important safeguards:
 
•  Never attempt to manually light the burners with a match 
or other source of flame.
•  Read and follow the operating instructions 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 furnace 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 procedures on the furnace, or in the 
“Shutting Down Your Furnace” section and call your dealer 
as soon as possible.
