It may seem "not too hard" but nevertheless it is a project for a LICENCED gas fitter!

Correct...officially. I find it amusing that they give all the part numbers of the bits required and distances etc. and even retail not trade prices. Clearly they are advertised for sale to the general public just like Bunnings or any electrical or plumbing store sell mainly to the public not the trade. Officially the untrained should not attempt work like this or even changing a tap washer, but they do in droves.
