instructions exactly.

• Do not attempt to light any appliance.

• 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 technician. Force or attempted repair may
result in a fire or explosion.
D. Do not use this appliance if any part of it has been under water. Immediately call a qualified service tech-
nician to inspect the appliance and to replace any part of the control system and any gas control that has
