Step 10: Burner Test and Adjustment
Install any loose components, such as burner caps and
grates, that may have been removed earlier. Be certain that
burner caps seat properly into the burner bases. Before
testing operation of the appliance, verify that the unit and
the gas supply have been carefully checked for leaks and
that the unit has been connected to the electrical power
supply. Turn the gas shut-off valve to the open position.
NOTICE:
All oven knobs and selectors must be set to OFF before
powering up the range. To prevent unintended operation at
power up, please set all oven knobs to OFF. To ensure
customer safety in the event of power failure, the unit will
display an error message upon reinstatement of power
unless all oven knobs are set to OFF. Set all oven knobs to
OFF and reset the breaker to clear the message.
Test Rangetop Burners
Test Burner Ignition. Select a rangetop burner knob. Push
down and turn counterclockwise to HI. The ignitor/spark
module will produce a clicking sound. Once the air has
been purged from the supply lines, the burner should light
within (4) seconds.
Test Flame: High Setting. Turn burner on to HI. See
Figure 33
for appropriate flame characteristics.
If any of the rangetop burners continue to burn mostly or
completely yellow, verify that the burner cap is positioned
properly on the burner base, then retest. If flame
characteristics do not improve, call THERMADOR
®
.
Test Flame: Simmer Setting. Turn burner on to SIM. Verify
that the flame travels completely around the burner. This is
known as “carry over.” There should be a flame at each
burner port and there should be no air gap between the
flame and the burner. If any burners do not “carry over,” call
THERMADOR.
Four rangetop burners, (2) on the left side and (2) on the
right, feature the XLO
®
setting that causes the flame to
cycle on and off when the knob is set to the XLO range.
This is normal operation.
When Flame is Properly Adjusted:
There should be a flame at each burner port. There should
be no air gap between the flame and burner port.
Repeat these Ignition and Flame Test procedures for each
rangetop burner.
Figure 33:
Flame Characteristics
Yellow Flames:
Further adjustment is required.
Yellow Tips on Outer Cones:
Normal for LP Gas.
Soft Blue Flames:
Normal for Natural Gas.
If the flame is completely or mostly yellow, verify
that the regulator is set for the correct fuel. After
adjustment, retest.
Some orange-colored streaking is normal during
the initial start-up.
Allow unit to operate 4-5 minutes and re-evaluate
before making adjustments.
