phone in your building.

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 gas control knob. Never

use tools. If the knob will not turn by hand, don't try to
repair it, call a qualified service technician. Force or
attempted repair may result in 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 valve that has been under
