OPERATING HEATER
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 supplier, call the fire de-
partment.
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 techni-
cian 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.
WARNING: If you do not follow these instructions
exactly, a fire or explosion may result causing prop-
erty damage, personal injury or loss of life.
