Gas Line Under Concrete
Refresh my thoughts on this. Gas line under an outdoor concrete and flagstone slab. No sleeve or vent. It does not go under a building at any point, and it only under the concrete for about 2 feet until the concrete ends and it is underground for another six feet or so. Is it different for gas line under a slab that is not under the house?

It comes from overhead along the patio eave, goes under the slab for a few feet, is under dirt for six feet or so, and then comes back up and goes into the pool house mechanical room sidewall.

Re: Gas Line Under Concrete
Based on your description, the IRC does not require a sleeve or vent (no sleeve to vent).
Maybe Bob H will see this and maybe there is something in NFPA 58 which addresses it, otherwise ... it is just stupidity to run a gas line under concrete, but at least it is not for very long (about 2 feet) so any leaking gas has a means to escape up through the soil and the cracks in the concrete/stones.

That was how I remembered it last time it came up.
