you have to turn each burner head about 1&1/2" CCW to release it from the top of the range.
Once released you can lift it up and remove the wiring and the top can be raised after releasing
the clips under the front edge.
They make a special wrench for removing the burners
however you may be able to do it with some other type of large pliers.
you will need to take great care when removing as its normal
to hear a little cracking and poping of the porcelin when removing but, can
crack severly if you rough with it.
