NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
WARNING: THE SIZE AND POSITION OF
THE LOG SET WAS ENGINEERED TO GIVE
YOUR APPLIANCE A SAFE, RELIABLE
AND ATTRACTIVE FLAME PATTERN. ANY
ATTEMPT TO USE A DIFFERENT LOG SET
IN THE FIREPLACE WILL VOID THE WAR-
RANTY AND WILL RESULT IN INCOM-
PLETE COMBUSTION, SOOTING, AND
POOR FLAME QUALITY.
WARNING: LOGS GET VERY HOT AND
WILL REMAIN HOT UP TO ONE HOUR
AFTER GAS SUPPLY IS TURNED OFF.
HANDLE ONLY WHEN LOGS ARE COOL.
TURN OFF ALL ELECTRICITY TO THE
APPLIANCE BEFORE YOU INSTALL
GRATE AND LOGS.
WARNING: THIS APPLIANCE IS NOT
MEANT TO BURN WOOD. ANY ATTEMPT
TO DO SO COULD CAUSE IRREPARABLE
DAMAGE TO YOUR APPLIANCE AND
PROVE HAZARDOUS TO YOUR SAFETY.
Logs and Rockwool (Glowing Embers)
Placement
The logs are packaged within the firebox.
The bag of rockwool is in the lower control
compartment. Remove the rockwool from
the packaging and tear into dime size pieces
(Figure 9). Spread across the burner in front
of the front log. See
Figure 10. Do not use
more than is necessary to cover the burner.
When properly positioned, the rockwool will
unevenly cover approximately 85% of the
front of the burner with no appreciable gaps.
These appliances are equipped with a beautifully
crafted four (4) piece ceramic fiber log set. The
logs, shown in
Figure 12 on page 8, are to be
positioned precisely as shown. Any modifica-
tion to the to the lay of these logs may result in
sooting, property damage and injury or death.

Millivolt Appliance Checkout
The gas control system on these appliances is
a millivolt standing pilot type. It consists of a
pilot burner, a piezo ignitor, a gas control valve,
a burner assembly and an ON/OFF wall switch.
A temperature limit switch is wired in series
with the millivolt wall switch and gas control
valve. If a higher than normal temperature is
sensed due to a blocked vent or prolonged
downdraft, the limit switch will open and cause
the burner to shut off.
The pilot flame should be steady, not lifting or
floating. Flame should be blue in color with
traces of orange at the outer edge.
The top ³⁄₈" (9 mm) at the pilot generator
(thermopile) should be engulfed in the pilot
flame
(Figure 11).
Figure 11
If the pilot flame pattern is not as shown in
Figure 11, adjust it as follows:
1. Remove the pilot adjustment cap located on
the main gas valve.
2. Adjust the pilot screw to provide properly
sized pilot flame
(Figure 10 ). Turn counter
clockwise to enlarge pilot flame and clockwise
to reduce the pilot flame. DO NOT attempt to
adjust pilot flame more than one half turn.
3. Replace the pilot adjustment cap.
Replace logs if removed for pilot inspection.
To light the burner; rotate the gas valve control
knob counterclockwise to the “ON” positionand
then turn “ON” the remote wall switch.
Electronic Appliance Checkout
The gas control system on these appliances is
an electronic low voltage gas control valve with
an intermittent ignitor. It consists of a low
voltage gas control valve, an intermittent igni-
tion system, an electronic control module, trans-
former and a burner assembly. A temperature
limit switch is wired in series with the gas
control valve. If a higher than normal tempera-
ture is sensed, due to a blocked vent or pro-
longed downdraft, the limit switch will open
and cause the burner to shut off.
The pilot flame should be steady, not lifting or
floating. Flame should be blue in color with
traces of orange at the outer edge.
To light the burner, push the gas control lever
in and toward the left to the “ON” position.
Turn ‘ON’ the remote wall switch. Ensure the
ignitor lights the pilot. The pilot flame should
engulf the ignitor.
WARNING: PILOT FLAME PATTERN
ADJUSTMENT SHOULD ONLY BE PER-
FORMED BY A QUALIFIED PROFES-
SIONAL SERVICE TECHNICIAN.
