Tubular And Wok Burner Performance And Final Air-Shutter Adjustments (If Necessary) - Thermador PLPKIT Conversion Instructions

(LP) Gas. Orange-colored streaks in the flame are
produced from burning airborne debris; this is normal
during initial start up and should dissipate within a few
minutes of operation.
• Adjust the burner's control valve or thermostat to "LO"
or "SIM" to see that the flame continues to wrap around
the burner. Blow out the flame, or use a quick fan
motion from a writing tablet or piece of cardboard to
extinguish the flame, and then observe the burner's
ability to re-ignite and wrap around ("carry-over") the
burner within several seconds. The flame "carry-over"
is essential for proper burner ignition and re-ignition.
• Test re-ignition of the two Star
of the appliance by turning the control knobs to "XLO"
and observe the carry-over of the small simmer flames
as the XLO system cycles the two burners on and off.
• If the flame performance is not acceptable, verify that
the burner has the correct size LP orifice installed, and
that the regulator has been properly converted for LP
Gas.
• For un-acceptable performance of a Star
verify that the burner cap is seated properly in its
burner base. The cap should fit reasonably flat when
correctly-positioned in the base and not rock
significantly.
• If the burner flame is uneven, flutters, makes excessive
noise, or lifts, some of the ports in the burner cap may
be blocked with food spillage or other debris. Clogged
ports can be cleared using a straightened paper clip,
needle, or similar object. This is also applicable for
blocked ports in Grill or Griddle Burners.
• Additionally, hardened food spillage or other debris can
block some of the small carry-over channels in the
®
Star Burner base, which can inhibit the flame from
wrapping around the burner. The channels can be
cleared using a wire brush.

Tubular and wok burner performance and
final air-shutter adjustments (if necessary)
Propane (LP) Gas is heavier, with greater density than
Natural Gas, and is distributed within the appliance at
higher pressure. The differences in properties and
application cause LP Gas to entrain different amounts of
primary air which usually requires different air-shutter
openings, as compared to Natural Gas applications for the
same or similar BTU ratings.
Burner for "solid plate" style Grill or Griddle
• A "too open" air shutter position creates noticeable
"lifting" (also called "blowing") of the flame - which can
degrade carry-over performance of the burner. This
condition can also create excessive noise.
• A flame that is "lazy", with excessively-long flames that
are reaching for air, is created by a "too closed" air
shutter. Many of the outer mantles of the individual
flames tend to "coalesce" or blend together. Excessive
yellow color in the flame can also occur with an
excessively-closed shutter.
If air-shutter adjustment is needed, remove the burner from
the appliance. Loosen the shutter's retaining screw using a
1/4-inch nut driver or wrench and rotate the shutter to its
new position. If less than 50% opening is desired, move the
retaining screw to the alternate location shown on the next
page and rotate the shutter to its new position. Re-install
