with an ignition device which automatically lights the
burner.

ance 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 neigh-
bor’s phone. Follow the gas supplier’s instructions.
• If you cannot reach your gas supplier, call the fire
department.
C. Use only your hand to turn the external manual gas
valve. Never use tools. If the valve will not turn by
hand, don’t try to repair it; call a qualified service tech-
nician. 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
