nace. (See Fig. 8.)
4.Remove the main furnace door.
(See Fig. 9.)
5.Gas valve will have EITHER a con-
trol switch or control knob to turn
OFF or ON. Turn control switch or
knob on the gas valve to the OFF
position and wait 5 minutes. (See
Fig. 10 or 11.) Then smell for gas,
including near the floor. If you
smell gas,
STOP!

7.Replace main furnace door.
(See Fig. 14.)
8.Turn on electrical supply to the fur-
nace and wait 1 minute.
(See Fig. 15.)
9.Open the external manual gas
valve. (See Fig. 16.)
10.Set room thermostat to a tem-
perature slightly above room
temperature. This will auto-
matically signal the furnace to
start.
11.When the furnace receives the start
signal, the inducer is started. When
the pressure switch verifies that
there is sufficient combustion air, the
control energizes the hot surface
ignitor. After the hot surface ignitor
is heated for 17 sec, the gas valve
permits gas to flow to the main burn-
ers. After ignition and a time delay
of 60 sec, the furnace blower starts.

NOTE:
If the burners fail to ignite after
4 attempts, the furnace control system
will lock out. If lockout occurs, main
burners fail to light, or blower does not
come on, shut down the furnace and
call your dealer for service.
12. Set your thermostat to the temper-
ature that satisfies your comfort
requirements.
SUGGESTION: Setting the ther-
mostat back a few degrees and
compensating for the difference
with warmer clothing can make a
big difference in your fuel con-
sumption on extremely cold days.
The few degrees at the top of your
thermostat “comfort level” are the
most costly degrees to obtain.
When room temperature drops
below the temperature selected
on the thermostat, the furnace
will be switched on automatically.
When room temperature reaches
the degree selected on the thermo-
stat, the furnace will be switched
off automatically.
Some thermostats have a FAN
mode with 2 selections, AUTO
and ON. When thermostat is set
to AUTO, the furnace blower
cycles on and off, controlled by
the thermostat. In ON mode, the
furnace blower runs continu-
ously. This keeps the temperature
level in your home more evenly
balanced. It also continuously fil-
ters the indoor air.
