Press in and turn control knob clock-
wise 

  to the OFF position (see

Figure 21).

5.

Wait five (5) minutes to clear out any
gas. Then smell for gas, including

  to the PILOT

position. Press in control knob for

Note: 

You may be running this

heater for the first time after hook-

trol knob may need to be pressed in
for 30 seconds or less. This will allow
air to bleed from the gas system.

and release ignitor button. This will
light pilot. The pilot is attached to the
front burner. If needed, keep press-
ing ignitor button until pilot lights.

tact a qualified service person or gas
supplier for repairs. Until repairs are
made, light pilot with match. To light
pilot with match, see Manual Light-
ing Procedure, 
page 15.

Keep control knob pressed in for 30
seconds after lighting pilot. After 30
seconds, release control knob.
• If control knob does not pop out when

released, contact a qualified service
person or gas supplier for repairs.

Note:

 If pilot goes out, repeat steps

4 through 8.

OPERATING
HEATER

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 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 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 con-
trol 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. 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:

 Home owners 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.

1.

STOP! Read the safety information,
column 1.

2.

Make sure manual shutoff valve is
fully open.

3.

Set selector switch in the OFF position.

 WARNING: Damper handle

will be hot if heater has been
running.
