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 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
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.
