Whilst this appliance looks very nice, clean and sparkling, the big disappointment was, that although the measurement (600) was the same as the old one, the new model is quite a bit smaller, therefore leaving a hole in the bench top. The installer has made arrangements for a piece of powder coated steel for a fill in, but as that is yet to come, I've no idea what the result will look like. I am also finding that the flow of gas seems to be a lot less that my previous model something I will obviously have to get used to.
