phone. Follow the gas supplier’s instructions.

If you cannot reach your gas supplier, call the fire
department.
C. Use only your hand to push in or turn the gas control knob.
Never use tools. If the knob will not push in or turn by
hand, don’t try to repair it, call a qualified service techni-
cian or gas supplier. Force or attempted repair may result
in a fire or explosion.
D. Do not use this appliance if any part has been under water.
Immediately call a qualified service technician to inspect the
appliance and to replace any part of the control system and
any gas control which has been under water.

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
burner to remain fully on, without modulating down in most cases.
