SAFETY

This is a safety alert symbol. When you see this symbol on
labels or in manuals, be alert to the potential for personal
injury.
Understand and pay particular attention to the signal words DANGER,
WARNING, or CAUTION.
DANGER indicates an imminently hazardous situation, which, if not
avoided, will result in death or serious injury.
WARNING indicates a potentially hazardous situation, which, if not
avoided, could result in death or serious injury.
CAUTION indicates a potentially hazardous situation, which, if not
avoided may result in minor or moderate injury. It is also used to
alert against unsafe practices and hazards involving only property dam-
age.
Note the following:
• Make sure that the furnace area is clear and free of combustible
materials, gasoline, and other flammable vapors and liquids.
• For proper operation of the furnace, air for combustion and venti-
lation is required. Make sure that these openings are not
obstructed.
• For lighting or shutting down the furnace, refer to the lighting
instructions that are provided adjacent to the burners and in this
manual.
• A burner inlet pressure switch is provided in the burner compart-
ment. If the furnace fails to operate, contact a qualified service
agency.
• If the gas supply fails to shut off or if overheating occurs, shut off
the gas valve to the furnace before shutting off the electrical sup-
ply, then call a qualified service technician.
