Best Way to Install Underground Natural Gas Line

[lawfarm]

Ok...so this is garage related...

We're installing a stamped concrete patio behind our garage, and I'd like to install a natural gas firepit/burner setup (I'll buy a burner and build a block enclosure for it) after the patio is poured. I have stubbed a 1/2" black pipe natural gas line to the rear of the house/garage area, ready to be tapped on to. What is the best way to do the outside portion of the gas line? Can iron pipe be directly buried? Should I put it right in the slab? Should I use a different material other than iron pipe? Should I use pipe but sleeve it with something? The burners all appear to have 1/2 NPT threaded inlets on them.

Any suggestions?

Iron pipe is fine for direct bury but usually must be painted (usually green) or wraped with tape. Shut off valve near appliance. Plastic PE pipe is typically frowned on under slab.

Black iron pipe for burial has a tar coating on it and is spiral wrapped with a brown paper. I would not bury plain black pipe.

call your local gas company,they can do the install with the right pipe.thats what i do.

Or that black tar glop.

Be careful with the idea, if it comes to mind, to sleeve the gas line. Check that with your inspector. I know they don't sleeve propane. Not sure about natural gas.

I'm in an area where there is no permit and no inspection. Not even if you want one. What about CSST? That looks like it would fit the bill nicely. It can be direct buried, and is flexible so there'd be no underground joints. Anyone have any experience with that?
