4. Locate the two (2) latches at the top of the
control compartment. To disengage the two
latches from the bottom vee-flange of the glass
enclosure panel, reach for the handles located
towards the back of the latches and pull the
handles down toward the front of the unit.
5. Swing the bottom of the door out and raise
it slightly to lift the top flange of the door frame
away from the appliance.
To install the front glass enclosure panel,
proceed as follows:
1. Visually inspect the gasket on the backside
of the panel. The gasket surface must be clean,
free of irregularities and seated firmly.
2. Position the glass enclosure panel in front
of the firebox opening at a 45 degree angle and
engage the top flange over the lip at the top of
the firebox opening.
3. Swing the glass enclosure panel down and
back. Ensure the gasket seats evenly as the
panel draws shut. Engage the Vee-flange at
the bottom of the panel with the latches and
close the latches to secure the panel.
4. Reinstall the bottom control compartment
access panel by inserting the right side locat-

Burner Adjustments

The following paragraphs address burner ad-
justment concerns and procedures.

Flame Appearance and Sooting

Proper flame appearance is a matter of taste.
Generally most people prefer the warm glow of
a yellow to orange flame. Appliances operated
with air shutter openings that are too large will
exhibit flames that are blue and transparent.
These weak, blue and transparent flames are
Firebox Floor
termed anemic. If the air shutter opening is too
EDVST SHOWN
small sooting may develop.
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
Sooting is indicated by black puffs developing
at the tips of very long orange flames. Sooting
results in black deposits forming on the logs,
appliance inside surfaces and on exterior sur-
faces adjacent to the vent termination.
Sooting is caused by incomplete combustion
in the flames and a lack of combustion air
entering the air shutter opening. To achieve a
warm yellow to orange flame with an orange
body that does not soot, the shutter opening
must be adjusted between these two extremes.
No smoke or soot should be present. Reposi-
tion the log set if the flames impinge on any
part of it.
If the log set is properly positioned and sooting
conditions exist, the air shutter opening on the
main burner tube should be adjusted. Normally,
the more offsets in the vent system, the greater
the need for the air shutter to be opened further.
WARNING: AIR SHUTTER ADJUSTMENT
SHOULD ONLY BE PERFORMED BY A
QUALIFIED PROFESSIONAL SERVICE
TECHNICIAN.
ENSURE THAT ALL GLASS PANELS ARE IN
PLACE AND SEALED DURING ADJUSTMENT.

Adjustment

CAUTION: THE ADJUSTMENT ROD AND
NEARBY APPLIANCE SURFACES ARE HOT.
EXERCISE CAUTION TO AVOID INJURY WHILE
ADJUSTING FLAME APPEARANCE.
To adjust the flame, rotate the adjustment rod
(located in the lower control area) counterclock-
wise to decrease or clockwise to increase the air
shutter opening. Adjust the air shutter to the
recommended setting as shown in Figure 5 on
page 7 . Allow the burner to operate for at least 15
minutes. Observe the flame continuously. If it
appears weak or sooty as previously described,
adjust the air shutter by rotating the adjustment
rod until the flame appearance is as desired.
The adjustment rod and associated adjustable air
shutter is patented technology. Flame adjust-
ments can be made quickly and accurately to taste
without the need of disassembling the appliance
and waiting for 30 minutes after each adjustment.
Propane models may exhibit a flame pattern
that may candle or appear stringy. If this is
problematic or persists as the appliance is
continually operated, adjust the air shutter
closed as described in the previous paragraphs.
