All the literature I have seen says heat resisting glass - this is from Dometic website - as
@t0mb0 says, mad design if not heat resiting. I would still put something on it but only to stop scratches, a bar mat is cool but we also make choppping boards for our customers if needed.

Flush fit with glass lid
Our HBG series gas hobs are fitted perfectly flush with the surrounding worktop, and even offer extra worktop space when its
heat-resistant safety glass lid is folded down. For a smarter looking kitchen.
