FOR YOUR SAFETY
READ 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 be lighted by hand. When lighting the pilot, follow these instructions exactly.
B.BEFORE LIGHTING 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.
WHAT TO DO IF YOU SMELL GAS
•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 neighborʼs phone. Follow the gas supplierʼs 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, donʼt try to repair it, call a qualified service tech- nician or gas supplier. 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.
