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 fur-
nace, though, you should understand how
your furnace does its job.
When you set your thermostat to provide
more heat in your home, you are starting the
heating cycle of the furnace. First, the
inducer motor starts to purge the heat
exchanger of any remaining gasses. Next,
the hot surface ignitor glows and after a
warm-up period the gas valve opens and
ignition occurs. A short time later the blower
starts and distributes the warm air through-
out the home. When the temperature set on
your thermostat is reached, the gas valve
closes, the main burners are turned off, and
the blower continues to run until the remain-
ing warm air in the system is distributed.
When the blower stops, the heating cycle
has ended.
KEEP THE FURNACE AREA
CLEAR
NEVER
. . . use the area around your fur-
nace 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.
Do not block or obstruct air openings:
1. On the furnace.
2. Air openings communicating with the
air in which the furnace is installed.
3. The spacings around the furnace.
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
2
your home. These materials vaporize easily
and are extremely dangerous.
NEVER
. . .store cleaning materials near
your furnace. Materials such as bleaches,
detergents, powdered cleansers, etc., can
cause corrosion of the heat exchangers.
Insulating materials may be flammable.
When a furnace is installed in an attic
or other insulated space, or if insula-
tion is added, examine the furnace
area to ensure that the furnace is
kept clear and free of insulation.

FULLY and COMPLETELY.
Before attempting to start your furnace,
always do the following things FIRST:
•
Turn the thermostat OFF.

If you do not follow these instruc-
tions exactly, a fire or explosion may
result, causing property damage,
personal injury or loss of life.

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.

BEFORE OPERATING, smell all
around the appliance area for gas. Be

some gas is heavier than air and will
settle on the floor.
