WARNING: Do not operate heater between PILOT
and HIGH positions.
1. STOP! Read the safety information page 15, column 2.
2. Make sure equipment shutoff valve is fully open.
3. Press in and turn control knob clockwise
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! Fol-
low “B” in the safety information page 15, column 2. If you
don’t smell gas, go to the next step.
5. Slightly depress and turn control knob counterclockwise
C-clockwise
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 supply. If so, the control knob may
need to be pressed in for 30 seconds or more. This will al-
low air to bleed from the gas system.
6. With control knob pressed in, press and release ignitor but-
ton. This will light pilot. The pilot is attached to the burner.
If needed, keep pressing ignitor button until pilot lights.
WARNING:
• If fireplace has glass doors, never operate this
heater with glass doors closed. If you operate
heater with doors closed, heat buildup inside fire-
place 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 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.
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 17.
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.
• If control knob does not pop out when released, contact
a qualified service person or gas supplier for repairs.
8. Slightly depress and turn control knob counterclockwise
C-clockwise
to desired heating level. The burner should light.
Set control knob to any heat level between HI and LO.

CAUTION: Do not try to adjust heating levels by
using the equipment shutoff valve.
The variable control valve can be set to any heat setting and
flame height desired, by simply turning the control knob until
that setting is attained. Even the lowest setting provides realis-
tic, dancing yellow flames. Selecting higher settings produces
greater heat output. This results in increased heating comfort.
