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 pres-
ent. Open damper or window to
vent smell. This will only last a
few hours.
Note: Home owners generally prefer to op-
erate 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 chimney 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 in
column 2, page 18.
2. Make sure equipment shutoff valve is
fully open.
3. Turn control knob clockwise to the
OFF position.
4. Wait five (5) minutes to clear out any gas.
Then smell for gas, including near the floor.
If you smell gas, STOP! Follow “B” in the
safety information in column 2, page 18. If
you donʼt smell gas, go to the next step.

5. Turn control knob counterclockwise
to the PILOT position. Press in control
knob for five (5) seconds (see Figure 25).
Note: You may be running this heater for
the first time after hooking up to gas sup-
ply. If so, the control knob may need to be
pressed in for 30 seconds or more. This will
allow air to bleed from the gas system.
• If control knob does not pop out when
released, contact a qualified service
person or gas supplier for repairs.
6. With control knob pressed in, press and
release ignitor button. This will light pilot.
The pilot is attached to the front burner. If
needed, keep pressing ignitor button until

Note: If pilot does not stay lit, contact a
qualified service person or gas supplier for
repairs. Until repairs are made, light pilot
with match. To light pilot with match, see
Manual Lighting Procedure, page 20.
7. Keep control knob pressed in for 30 seconds
after lighting pilot. After 30 seconds, release
control knob.
Note: If pilot goes out, repeat steps 3
through 7. This heater has a safety interlock
system. Wait one (1) minute for system to
reset before lighting pilot again.
8. Turn control knob counterclockwise
to desired heating level. The burners should
light. Set control knob to any heat level
between HI and LO.
CAUTION: Do not try to ad-
just heating levels by using the
equipment shutoff valve.
