NOTE: It is normal for slight yellow tipping of the flames
to appear after a few minutes of operation using propane
(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.
Yellow flames:
Further adjustment is
required.
Yellow tips on outer cones:
Normal for LP gas
Soft blue flames:
Normal for natural gas
2. Adjust the burner's control valve 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 reignite and wrap around (also called "carry-
over") the burner within several seconds. This flame
"carry-over" is essential for proper burner ignition and
re-ignition.
3. Test re-ignition of the "XLO
over of the small simmer flames as the XLO system
cycles the burners on and off.
• If the flame performance is not acceptable it may
be necessary to readjust the valve screw for a top
burner that does not have sufficient carry-over of
the flame. Turn the valve screw very slightly
counter-clockwise until carry-over of the flame is
acceptable. (See "Setting the STAR® burner valve
screws").
• If the burner flame is uneven, flutters, makes
excessive noise, or lifts, some of the slots in the
burner base may be blocked with food spillage or
other debris. Clogged slots can be cleared using a
straightened paper clip, needle, or similar object.
Hard-to-remove, encrusted food or debris can
sometimes be removed using a steel wool pad or
fine wire brush.

• Burner flames that are "lazy", with excessively-
long flames, can be created by an incorrectly
fitted burner cap—from which many of the outer
mantles of the individual flames will tend to
"coalesce" or blend together. Verify that the
burner cap is seated properly on its burner base.
The cap should fit reasonably flat when correctly-
positioned on the base and not rock significantly.

4. Repeat the ignition and flame test procedures for
each rangetop burner.
5. Test gas broiler ignition (GAS range only). Turn the
mode knob and the oven temperature knob to
"BROIL".
• The hot-surface igniter will attempt to light the
broiler after approximately 45 to 90 seconds, as
the safety valve coil heats to open. Once the air
has been purged from the gas supply line, the
broiler should light within four (4) seconds.
• The ceramic tiles of the burner should glow red
hot (infrared) after several minutes of operation. If
after several minutes with the burner lit, the
broiler only has a small amount of red glow (and
burns mostly with blue flame floating on the
burner surface), check that the broiler orifice is
aligned to the center of the burner tube inlet.
6. Repeat for the bake burners.
