THERMOSTAT CONTROL
OPERATION
The thermostat control knob can be set to
any comfort level between Hi and Lo. The
thermostat will gradually modulate the heat
output and flame height from higher to
lower settings, or pilot, in order to maintain
the comfort level you select. The ideal com-
fort setting will vary by household depend-
ing upon the amount of space to be heated,
the output of the central heating system, etc.

INSPECTING
BURNERS
Check pilot flame pattern and burner flame
patterns often.
PILOT FLAME PATTERN
Figure 23 shows a correct pilot flame pat-
tern. Figure 24 shows an incorrect pilot
flame pattern. (
Note: Appearance of pilot
assembly may vary by model). The incor-
rect pilot flame is not touching the thermo-
couple. This will cause the thermocouple to
cool. When the thermocouple cools, the heater
will shut down.
If pilot flame pattern is incorrect, as shown
in Figure 24
• turn heater off (see To Turn Off Gas to
Appliance)
• see Troubleshooting, pages 16 through 18

CAUTION: Do not try to adjust
heating levels by using the equip-

Note: Selecting the Hi setting with the
control knob will cause the burners to
remain fully on, without modulating down
in most cases.
Continued
Light your gas appliance with the blower
off. Turn the blower on to deliver heated
air at the top louvers. The blower fea-
tures a variable control which allows you
to select the speed you desire.
If using the GA3650TA Blower Accessory:
In the ON position, the blower will start
when the thermostat senses a sufficient
increase in firebox temperature (approxi-
mately 10 to 20 minutes depending on
heat setting).
Note: Your gas stove and
thermostat blower will not turn on and
off at the same time. The stove may run
for several minutes before the blower
turns on. After the heater modulates to
the pilot position, the blower will con-
tinue to run. The blower will shut off
after the firebox temperature decreases.
Note: It is safe to operate stove with
blower turned off. However, the blower
helps distribute heated air from the stove.
Note: Periodically check the louvers of
the firebox and remove any dust, dirt, or
other obstructions.
