FOR YOUR SAFETY READ BEFORE OPERATING
OPERATING INSTRUCTIONS
TO TURN OFF GAS TO THE APPLIANCE
•
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 neighbor's phone.
Follow the gas supplier's instructions.
•
If you cannot reach your gas supplier, call the fire department.
WHAT TO DO IF YOU SMELL GAS
A. This appliance does not have a pilot. It is equipped with an
ignition device which automatically lights the burner. Do
not try to light the burner by hand.
B. Before OPERATING, smell all around the appliance area
for gas. Be sure to smell next to the floor because some gas
is heavier than air and will settle on the floor. See below.
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 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.
If you do not follow these instructions exactly, a fire or explosion may result
causing property damage, personal injury or loss of life.
