FOR YOUR SAFETY READ BEFORE OPERATING

WARNING:

 If  you do not follow these  instructions exactly,  a fire or explosion 

may result causing property damage, personal  injury, or loss of life. 

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

the fire  department.

Never use tools.  If the handle 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.

under water.  Immediately call a qualified
