OPERATING HEATER

FOR YOUR SAFETY

READ BEFORE LIGHTING

 WARNING: If you do not fol-

low these instructions exactly,
a fire or explosion may result
causing property damage, per-
sonal injury or loss of life.

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 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 tech-
nician 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 ser-
vice technician to inspect the appliance and
to replace any part of the control system and
any gas control which has been under water.

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. Make
sure there are no obstructions
across opening of fireplace.

• 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 win-
dow to vent smell. This will only
last a few hours.

Note:

 Home owners generally prefer to oper-

ate 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 highest heat setting but will
find the heat output excessive. You can open the
chimney damper (if you have one) fully or par-
tially to release some of the heat.

 WARNING: Damper handle

will be hot if heater has been
running.

 WARNING: Burners will

come on automatically within
one minute when the control
valve is in the ON position after
the pilot is lit.

1.

STOP! Read the safety information in
column 1.

2.

Make sure equipment shutoff valve is
fully open.

3.

Set remote selector switch in the AUTO
position (see Figure 32, page 20).
