FOR YOUR SAFETY, READ BEFORE LIGHTING

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  has  a  pilot  which  must  be  lighted  by  hand. 
When lighting the pilot, follow these Instructions exactly. 

B. 

BEFORE  LIGHTING  smell  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. 

 

WHAT TO DO IF YOU SMELL GAS 

 

• Do not try to light any appliance or strike a match. 

 

• Do not touch any electric switch; do not use any phone  or cell 

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.
