FOR YOUR

SAFETY READ

BEFORE LIGHTING

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.

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.

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 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.
