Test rangetop burners
See figures below 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 re-test. If flame
characteristics do not improve, call Thermador service.
To test burner ignition
1. Select a rangetop burner knob. Push in and turn the
knob to HI.
• The igniter will produce a clicking sound. Once
the air has been purged from the supply lines, the
burner should light within four seconds.
2. Turn burner 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 service.
3. Repeat the ignition and flame test for each rangetop
burner.
The burners that feature XLO
®
, cause the flame to cycle
on and off when the knob is set to the XLO function. 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.
Call Thermador service if:
• Any of the burners do not light.
• Any of the burners continue to burn yellow.
