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 24 shows a correct pilot flame pat-
tern. Figure 25 shows an incorrect pilot flame
pattern. The incorrect pilot flame is not touch-
ing the thermocouple. This will cause the
thermocouple to cool. When the thermo-
couple cools, the heater will shut down.
If pilot flame pattern is incorrect, as shown
in Figure 25
• turn heater off (see To Turn Off Gas to
Appliance)
• see Troubleshooting, pages 16 through 18

Pilot Burner
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.
