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.

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
