My suggestion: "Gas piping should be of like material to prevent deterioration. Safety concern. Recommend a licensed plumber to repair to industry standards."

Like materials? Where does that come from Joe? Just curious.

Sloppy? Sure. Unsupported? Yep. A violation? Hmmm.

I'd be more concerned about that soft copper hanging out unsupported or protected. That's the biggest danger I see in this pic. One little kick and you could get a leak. The CSST should be btw a flanged fitting or something more stable--not a copper tongue sticking out. All these materials are approved in the gas codes and I'm not aware of any provision against combining them. The copper can be used only if you know there is less than 0.3 grains of hydrogen sulfide per 100scf.

I would recommend they check on the type of gas supplied and the HSO issue. Then have it re-piped so there is better support. Since this is not a fireplace buried inside a chase, there should be a sediment trap. That 3.8ths copper line is probably grossly undersized.

Just my 3 cents worth.

Like materials if just a generic term that I use when it looks like the plumbing was assembled from "everything-on-this-bench-is-one-dollar" hardware store.

UPC section 1210.4 states "All valves and appurtenances used in connection with the above piping shall be of a type designed and approved for use with fuel gas."

If an inspector wants to reach beyond his SOP, he must be certain that the yellow brass fittings do not contain more than 75% copper (section 1210.1) and no copper may be used if the gas contains more than 0.3 grains of hydrogen sulfide per 100 standard cubic feet of gas (section 1210.1.1).
