SAFETY CONSIDERATIONS
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.

To minimize the possibility of serious personal injury, fire,
furnace damage, or improper operation;
carefully follow
these safety rules:
• Your gas furnace uses air from outside the home for com-
bustion and venting. It is not to be installed using indoor air
for combustion. Both pipes must terminate outside the struc-
ture and must not be obstructed in any way. Do not block or
obstruct the furnace opening or area around the furnace.
• Keep the area around your furnace free of combustible
materials, gasoline, and other flammable liquids and vapors.
6
• 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 the furnace is installed or when insulation is
added. Some materials may be combustible.
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.
STARTING AND SHUTTING DOWN
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 inside of
main furnace door, 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 inside of main furnace
door, or in the “Shutting Down Your Furnace” section and
call your dealer as soon as possible.
•
CHECK AIR FILTER:
Before attempting to start your
furnace, be sure the furnace filter is clean and in place. See
“Performing Routine Maintenance” section in this manual.
Then proceed as follows:
STEPS FOR STARTING YOUR FURNACE
1. Set your room thermostat to the lowest temperature set-
ting. (See Fig. 8.)
2. Close the external manual gas valve. (See Fig. 9.)
!
WARNING
If overheating occurs or the gas valve fails to shut
off the gas supply, turn off the manual gas valve to
the furnace BEFORE turning off the electrical sup-
ply. (See Fig. 9.) Failure to follow this warning
could result in a fire or explosion, and personal in-
jury or death.
