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 pi-
lot, 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.

• 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 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.
