bEFORE LIGHTING

 WARNING: If you do not fol-

low  these  instructions  exactly, 

a  fire  or  explosion  may  result 

causing property damage, per

-

sonal injury or loss of life.

A.  This appliance has a pilot which must

-

lot, follow these instructions exactly.

• 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.
