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 ex-
actly.

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 try to light any appliance.
• Do not touch any electric switch;

do not use any phone in your build-
ing.

• 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 control which has been un-
der water.

 

 WARNING: If you do not fol-

low these instructions exactly, a
fire or explosion may result caus-
