STARTING YOUR FURNACE
Your furnace uses an automatic, hot surface ignition system to light
the burners each time the thermostat signals the furnace to start.
Follow these important safeguards:
S Never attempt to manually light the burners with a match
or other source of flame.

S Read and follow the operating instructions on inside of
main furnace door, especially the item that reads as fol-
lows:
“Wait 5 minutes to clear out any gas. Then smell for gas,
including near the floor. If you smell gas, STOP! Fol-
low “B” in the safety information above on this furnace
label. If you don’t smell gas, go to the next step.”
S 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 Fur-
nace” section and call yourdealer as soon as possible.
FIRE AND EXPLOSION HAZARD
Failure to follow this warning could result in personal injury,
death or property damage.
Should the gas supply fail to shut off or if overheating occurs,
turn off the manual gas valve to the furnace BEFORE turning
off the electrical supply and install lockout tag.
