Step 7: 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 manual gas shut-off valve to the
open position.
Test Cooktop Burners
Test Burner Ignition. Select a cooktop burner knob. Push
in 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 four (4) seconds.
Test Flame: High Setting. Turn burner on to HI. See
Figure 13 for appropriate flame characteristics. If any of the
cooktop burners continue to burn mostly or completely
yellow, verify that the burner cap is positioned properly on
the burner base, then re-test. If flame characteristics do not
improve, call Thermador.
Test Flame: Low Setting. Turn burner on to LO. Verify
that the flame completely surrounds the burner. 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.
The two far left burners feature XLO, causing the flame to
cycle on and off when the knob is set to the XLO range.
This is normal operation.
Repeat the Ignition and Flame Test procedures described
above for each cooktop burner and the grill burner (if so
equipped).

WHEN FLAME IS PROPERLY ADJUSTED:
•
•
The gas grill uses a tube-style burner that has an air shutter
which allows adjustment to the amount of primary air inside
the burner tube.
Air shutters of tube-style burners are pre-adjusted at the
factory, and usually do not require readjustment except
under rare conditions such as installation at high altitude.
If grill burner/flame adjustment is required, go to the
procedure: "Flame Adjustment (if necessary)".

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.
There should be a flame at each burner port.
There should be no air gap between the flame and
