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 comfort setting will
vary by household depending upon the amount of space to be heated,
the output of the central heating system, etc.
Note:
Selecting the Hi setting with the control knob will cause
the burners to remain fully on, without modulating down in
most cases.

CAUTION: Do not try to adjust heating levels by
using the equipment shutoff valve.
Ignitor Electrode
Light your gas appliance with the blower off. Turn the blower on
to deliver heated air at the top louvers. The blower features 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 (approximately 10 to 20 min-
utes 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
continue to run. The blower will shut off after the firebox
temperature decreases.
Note:
It is safe to operate stove with blower turned off. How-
ever, 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.
