INSTRUCTIONS
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. Make sure there are
no obstructions across openings 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, burn-
ing 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 High 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 on page 17, column 2.
2. Make sure equipment shutoff valve is fully open.
3. Press in and turn control knob clockwise
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 on page 17, column 2. If
you don't smell gas, go to the next step.
5. Press in control knob and turn counterclockwise
to the PILOT position. Keep control knob pressed in for
five (5) seconds (see Figure 27).
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 allow
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 front
burner. If needed, keep pressing ignitor button until pilot lights.
Note: If pilot does not light, 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 19.

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 realistic
flames and glowing embers from two burners. Selecting higher
settings produces greater heat output. This results in increased
heating comfort.
WARNING: Do not operate heater between locked
positions.
CAUTION: Do not try to adjust heating levels by
using the equipment shutoff valve.
