The burner caps must be properly placed on the burner bases for the cooktop to function properly. If the burner cap is not properly placed, one or more of the following problems may occur: • Burner flames are too high. • Flames shoot out of burners. • Burners do not ignite. • Burner flames light unevenly. • Burner emits gas odor. 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. 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. 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. Page. 23
