Step 7: Burner Test And Adjustment - Thermador P24GE Installation Instructions Manual

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 appli-
ance, 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 sup-
ply. 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 characteris-
tics.
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).
FIG. 13 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-eval-
uate before making adjustments.
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.
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-adjust-
ed at the factory, and usually do not require re-
adjustment except under rare conditions such as
installation at high altitude.
If grill burner/flame adjustment is required, go
to the procedure: "Flame Adjustment (if neces-
sary)".
