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-

LIGHTING
INSTRUCTIONS
WARNING:
• If fireplace has glass doors,
never operate this heater with
glass doors closed. If you op-
erate heater with doors closed,
heat buildup inside fireplace
will cause glass to burst. Also
if fireplace opening has vents
at the bottom, you must open
the vents before operating
heater.
• You must operate this heater
with a fireplace screen in place.
Make sure fireplace screen is
closed before running heater.
NOTICE: During initial operation
of new heater, burning logs will
give off a paper-burning smell.
Orange flame will also be present.
Open damper or window to vent
smell. This will only last a few
hours.
Note: Homeowners generally prefer to
operate their heater with the chimney
damper closed. This will put all the heat
into the room. However there may be
times you will desire the full flames of the
Hi heat setting but will find the heat
output excessive. You can open the chim-
ney damper (if you have one) fully or
partially to release some of the heat.
WARNING: Damper handle will be hot if
heater has been running.
1. STOP! Read the safety information
above.
2. Make sure manual shutoff valve is
fully open.
