HOW YOUR GAS
FURNACE WORKS
Your furnace is a very easy appli-
ance to take for granted. Season
after season, it sits there in your
home, keeping you warm and com-
fortable. 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 under-
stand 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 gas-
ses. 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 throughout the home.
When the temperature set on your
thermostat is reached, the gas
valve closes, the main burners are
turned off, and the blower contin-
ues to run until the remaining 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 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 vari-
ous furnace components.
1. On the furnace.
2. Air openings communicating
with the air in which the fur-
nace is installed.
3. The spacings around the fur-
nace.
NEVER . . . store flammable materi-
als of any kind near your furnace.
Gasoline, solvents, and other vola-
tile liquids should be stored only in
approved containers outside your
home. These materials vaporize
easily and are extremely danger-
ous.
NEVER . . . store cleaning materials
near your furnace. Materials such
as bleaches, detergents, powdered
cleansers, etc., can cause corro-
sion of the heat exchangers.

DOWN - GENERAL
