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
termed anemic. If the air shutter opening is too
small excessive sooting may develop.
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 face opening.
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.
These appliances should not smoke. Small
amounts of soot will accumulate over time and
should be expected. This soot adds to the
realism of the firebox interior. The logs can be
cleaned, when cool, with a
soft brush and
small amounts of water.
If the logs are properly positioned and exces-
sive sooting conditions exist, the air shutter
opening on the main burner tube should be
adjusted. Keep in mind that this is an outdoor
appliance. Wind and air currents cannot be
strictly controlled.
If the flame acts too erratically, we recommend
that the screens be closed.
Burner Adjustment
CAUTION: THE SHUTTER AND NEARBY AP-
PLIANCE SURFACES ARE HOT. EXERCISE
CAUTION TO AVOID INJURY WHILE ADJUST-
ING FLAME APPEARANCE.
To adjust the flame, turn the shutter (located in
the left side of the burner pan) up or down to
increase or reduce the air shutter opening,
respectively. Position the air shutter to the
factory setting, as shown in
Figure 4
.
WARNING: AIR SHUTTER ADJUSTMENT
SHOULD ONLY BE PERFORMED BY A
QUALIFIED PROFESSIONAL SERVICE
TECHNICIAN.
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.
Figure 4
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 shuter
until the flame appearance is as desired.
When satisfied that the appliance operates
properly, proceed to finish the installation.
Leave the control knob in ON position and
turn the remote switch OFF. Reinstall the
access and refractory cover.
