HOW YOUR GAS
FURNACE WORKS
Your furnace is a very easy appliance to
take for granted. Season after season, it
sits there in your home, keeping you
warm and comfortable. For this reason,
you may never have given much thought
to the way your furnace operates. In
order to get the safest and most efficient
operation from your furnace, though,
you should understand how your fur-
nace does its job.
When you set your thermostat to provide
more heat in your home, you are starting
the heating cycle of the furnace. The gas
valve inside the furnace opens to supply
gas to the burners. The hot surface ig-
niter lights the main burners. When the
temperature inside the furnace reaches
the operating level, the blower starts and
distributes the warm air throughout the
home. When the temperature set on the
thermostat is reached, the gas valve
closes, the main burners are turned off,
and the blower continues to run until the
remaining warm air in the system is dis-
tributed. When the blower stops, the
heating cycle has ended.
KEEP THE FURNACE
AREA CLEAR
NEVER . . . use the area around your
furnace as a storage area for items
which could block the normal flow of air.
This flow of air is required for ventilation
of the various furnace components.
NEVER . . . store flammable materials of
any kind near your furnace. Gasoline, sol-
vents, and other volatile liquids should be
stored only in approved containers outside
your home. These materials vaporize eas-
ily and are extremely dangerous.
NEVER . . . store cleaning materials
near your furnace. Materials such as
bleaches, detergents, powdered cleans-
ers, etc., can cause corrosion of the heat
exchangers.
WARNING: Insulating materials
may be flammable.
CAUTION: When a furnace is in-
stalled in an attic or other insu-
lated space, or if insulation is
added, examine the furnace to
ensure that the furnace is kept
clear and free of insulation.
START-UP AND
SHUTDOWN -
GENERAL
INSTRUCTIONS
Read and follow these procedures
CAREFULLY and COMPLETELY.
Before attempting to start your furnace,
always do the following things FIRST:
•• Turn the thermostat OFF.
•• Open windows or make other provi-
sions to ventilate the area around the
furnace.
•• If the blower is running, wait until it
shuts off automatically.
•• Turn off all electrical power to the
furnace.
•• Make sure all metal surfaces of the
furnace have cooled to room tem-
perature before beginning.
FOR YOUR SAFETY,
READ BEFORE
OPERATING:
A. This appliance does not have a pilot.
It is equipped with an ignition device
which automatically lights the burners.
Do not try to light the burners by hand.
B. BEFORE OPERATING, smell all
around the appliance area for gas.
Be sure to smell next to the floor
because some gas is heavier than
air and will settle on the floor.
WHAT TO DO IF YOU
SMELL GAS:
•• Do not try to light any appliance.
•• Do not touch any electrical switch; do
not use any phone in your building.
•• Immediately call your gas supplier
from a neighbor’s phone. Follow the
gas supplier’s instructions.
•• If you cannot reach your gas supplier,
call the fire department.
C. Use only your hand to turn the gas
control knob. Never use tools. If the
knob will not turn by hand, don’t try
to repair it. Call a qualified service
technician. Force or attempted re-
pair may result in a fire or explosion.
WARNING: Do not use this fur-
nace 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 underwa-
ter.
