Burner Cap Placement; Test Rangetop Burners - Thermador Professional Pro Grand Serie Instructions

Burner cap placement

Each cap has a letter (B, D, or F) cast in the underside of
the cap that corresponds to a letter (B, D, or F) cast in the
burner base that is attached to the appliance.
To place the burner caps
1. Place each burner cap on its correct burner base per
its corresponding letter designation.
2. Place burner cap gently on top of base so that the
prongs of the burner base fit snugly into the groove of
the burner cap.
Checking the burner cap placement
• Check each burner to make sure there is no gap
between the burner cap and burner base.
• You may gently try to move the burner caps from side
to side to check if the caps are properly placed on the
burner bases.
• When properly placed, each burner cap will rest flat
on top of its burner base, and completely cover the
star-shape of the burner base when viewed from the
top as shown below.

Burner grate placement
To install the burner grates
1. Place grates flat-side down and align into the
rangetop recess.
2. Grates should rest flush against each other and
against the sides of the recess.

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.
