Step 9: 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 supply. Turn the manual gas shut-off valve to the open position.

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 four (4) seconds.

Test Flame: High Setting. Turn burner on to HI. See Figure 14 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: 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 rangetop burners on the left side 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 rangetop burner and the grill burner (if so equipped).

FIG. 14 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 reevaluate 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 the primary air inside the burner tube.

Air shutters of tube-style burners are pre-adjusted at the factory, and usually do not require readjust- ment except under rare conditions such as installa- tion at high altitude.

If grill burner/flame adjustment is required, go to the procedure: "Flame Adjustment (if necessary)".
