FOR YOUR SAFETY
READ BEFORE
LIGHTING
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 neighbor’s phone. Follow
the gas supplier’s instructions.
If you cannot reach your gas sup-
plier, 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 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 con-
trol which has been under water.
WARNING: If you do not fol-
low these instructions exactly, a
fire or explosion may result caus-
ing property damage, personal
injury or loss of life.
