I need to run a gas line to a kitchen island for a Jenn-Aire range. I have a slab floor which I will have to saw cut to run both 240V electric and the gas. My question is, what type of piping is required for running the gas line in the slab and can I concrete over this line? I live in California, but am not sure what the code for this is. Any help would be greatly appreciated.

Thanks,

Frank Volpi
