Burner Adjustments
The following paragraphs address burner adjustment 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 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 surfaces 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. Reposition the logs if
the flames impinge on any of them.
If the logs are 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 THE FRONT GLASS PANEL IS 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, move the adjustment rod
(located in the lower control area) back or
forward to increase or reduce the air shutter
opening, respectively. Position the air shutter
to the factory setting as shown in
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 pushing or
pulling on the adjustment rod until the flame
appearance is as desired.
The adjustment rod and associated adjustable
air shutter is patented technology. Flame adjustments 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. Operate the appliance for a period of time as the
effect diminishes, ensuring that the appliance
does not develop sooty flames.
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.” Close the lower control
compartment door.
