Burner Adjustment
WARNING: AIR SHUTTER ADJUST-
MENT SHOULD ONLY BE PERFORMED
BY A QUALIFIED PROFESSIONAL
SERVICE TECHNICIAN.
CAUTION: THE AIR SHUTTER DOOR AND
NEARBY APPLIANCE SURFACES ARE HOT.
EXERCISE CAUTION TO AVOID INJURY
WHILE ADJUSTING FLAME APPEARANCE.
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 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 log set if 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.
To adjust the flame, rotate the adjustment rod
(located in the lower control area) counter-
clockwise to increase or clockwise to reduce
the air shutter opening.
Adjust the air shutter
to the recommended setting as shown in
Figure 52
.
Allow the burner to operate for at
least 15 minutes. Observe the flame continu-
ously. 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.
Step 9. BURNER ADJUSTMENTS
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 occur.
The adjustment rod and associated adjustable
air shutter is patented technology. Flame ad-
justments can be made quickly and accurately
to taste without the need of disassembling the
appliance and waiting for 15 minutes after each
adjustment.
Propane models may exhibit a flame pattern that
may candle or appear stringy. If this is problem-
atic or persists as the appliance is continually
operated, adjust the air shutter closed as de-
scribed in the previous paragraphs. Operate the
appliance for a period of time as the effect dimin-
ishes, ensuring that the appliance does not de-
velop sooty flames.
When you have verified that the appliance
operates properly, proceed to finish the in-
stallation. Leave the control knob in the ON
position and the remote switch OFF. Close
the lower control compartment door.
IMPORTANT: ENSURE THAT THE GLASS
ENCLOSURE PANELS ARE IN PLACE AND
SEALED DURING ADJUSTMENT.
A hearth extension is not required with this
appliance. If a hearth extension is used, do not
block the control compartment access panel.
Any hearth extension used is for appearance
only and does not have to conform to standard
hearth extension installation requirements.
Note:
Combustible wall finish materials and/
or surround materials must not be allowed
to encroach the area defined by the appli-
ance front face (black sheet metal). Never
allow combustible materials to be positioned
in front of or overlapping the appliance front
face. See
Figure 53
.
Non-combustible materials, such as surrounds and
other appliance trim, may be installed on the appli-
ance front face with these exceptions: they must not
cover any portion of the glass or louvers; they must
not cover any portion of the top radiant panel and the
air gaps surrounding the top radiant panel.
Vertical installation clearances to combustible
mantels vary according to the depth of the
mantel. See
Figure 54 on 24
. Mantels con-
structed of non-combustible materials may be
installed at any height above the appliance
opening; however, do not allow anything to
hang below the hood.
FINISHING REQUIREMENTS
Wall Details
Complete finished interior wall. To install the
appliance facing flush with the finished wall,
position framework to accommodate the thick-
ness of the finished wall (
Figure 53
)
Step 10.
HOOD INSTALLATION
All of these appliances must have hoods
installed on all sides with glass enclosure
panels prior to operating.
Slide the hoods into the slots on the lower edges of
the radiant panels
