Turn control knob clockwise to the OFF position.
Shutting Off Burners Only (pilot stays lit)
Turn control knob clockwise to the PILOT position.
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.
MANUAL LIGHTING
PROCEDURE
WARNING: If you do not follow these instructions
exactly, a fire or explosion may result causing prop-
erty damage, personal injury or loss of life.
A. This appliance has a pilot which must be lighted by hand.
When lighting the pilot, follow these instructions exactly.
B. BEFORE LIGHTING smell all around the appliance area
for gas. Be sure to smell next to the floor because some gas
is heavier than air and will settle on the floor.
WHAT TO DO IF YOU SMELL GAS
• Do not try to light any appliance.
• Do not touch any electric switch; do not use any phone in
your building.
• Immediately call your gas supplier from a neighbor’s
phone. Follow the gas supplier’s instructions.
• If you cannot reach your gas supplier, call the fire de-
partment.
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.
