INSTRUCTIONS TO THE USER
FOR YOUR SAFETY, READ BEFORE LIGHTING
WARNING
IF YOU DO NOT FOLLOW THE
WARNINGS BELOW AND THE
LIGHTING INSTRUCTIONS EXACTLY,
A FIRE OR EXPLOSION CAN RESULT
WITH PROPERTY DAMAGE, PERSONAL
INJURY OR LOSS OF LIFE.
Follow these warnings exactly:
1. Before lighting, smell around the appliance for
gas. Be sure to smell next to the floor because
LP gas is heavier than air.
2. IF YOU SMELL GAS:
• Turn off the gas supply at the appliance
service valve. On LP gas systems, turn off
gas supply at the gas tank.
• Do not light any appliances.
• Do not touch electrical switches or use the
phone.
• Leave the building and use a neighbor’s
phone to call your gas supplier.
• If you can not reach your gas supplier, call
the fire department.
3. Do not force the gas control knobs. Use only
your hand to turn the gas control knobs. Never
use any tools. If the gas control knobs will not
operate by hand, call a qualified service techni-
cian to replace the entire gas control. Force or
attempted repair can result in fire or explosion.
4. Call a qualified service technician to replace the
entire gas control if it has been flooded with
water.
5. Replace the entire gas control in the event of
any physical damage, tampering, bent termi-
nals, missing or broken parts, stripped threads,
or evidence of exposure to heat.
IMPORTANT: Follow the operating instructions pro-
vided by the manufacturer of your heating appliance.
The information below will be of assistance in a
typical control application, but the specific controls
used and the procedures outlined by the manufac-
turer of your appliance may differ, and require special
