Checking the STAR® burner performance
9 WARNING
When cooking with the STAR burners, the burner
flame size should be adjusted so it does not extend
beyond the edge of the cooking utensil. This
instruction is based on safety considerations.
To observe the burner flames, it may be necessary to turn
off lights or close window blinds to darken the room for
easier viewing of the flame.
Reassemble the rangetop as follows:
a. Grate
b. Burner cap
c.Venturi
d. Burner base
e. Electrode
1. Push in the burner control knob and turn it to “HI”.
•The igniter electrode and spark module will
produce a clicking sound. Once the air has been
purged from the supply lines, the burner should
light within four seconds.
•The flames should be stable, with no excessive
noise. The inner cones of the individual flames
should be defined and separate from each other.
Portions of the flame, along the burner, should not
exhibit excessive or continuous indications of
“lifting” or “lazy flame”.
a. Dark blue
b. Secondary cone
c.Light blue
d. Primary cone
f.Burner pedestal
g. Spill tray
h. Heat shield
i.Igniter housing
j.Igniter wire
TIP: Use the burner venturi as a centering guide when
remounting the burner pedestals. If the pedestals are
centered, the venturi will slide in and out easily after the T30 torx head screw has been secured. If the pedestals are
not centered properly, loosen the mounting screw and
recenter the burner until the venturi slides freely.
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

5. Adjust the burner’s control valve to LO to see that the
Star

Star
®
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.
6. Test re-ignition of the XLO and observe the carry-over
of the small simmer flames as the XLO system cycles
the burners on and off.
•If the low flame performance is not acceptable it
may be necessary to readjust the valve screw for a
®
STAR
burner that does not have sufficient carryover of the low flame. Turn the valve screw very
slightly counter-clockwise until carry-over of the
flame is acceptable. (See “Setting the STAR®
burner valve screws” on page 16.)
•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-toremove, encrusted food or debris can sometimes
be removed using a steel wool pad or fine wire
brush.
•Burner flames that are “lazy”, with excessivelylong 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.
