Messsssssss of a house today and I need some feedback here. Multiple splices into a standard rigid / cast propane supply line in a crawl space. The problem is the homeowner used rolled copper plumbing pipe instead of rigid / cast and is using compression fittings instead of threaded fittings...
I am looking all over the place to explain why it cannot be done this way but I am coming up short on this one.

Trey,

I don't think the soft copper is an issue, I could be wrong but it's past code inspections around here for as long as I can remember.

As for compression fittings, I don't think that is acceptable.

Copper is OK for propane, but I think flare fittings are preferred.

In my neck of the woods soft copper tubbing is excepted pratice for LP gas only. The LP companies go by different set of rules than the natural gas suppliers. Go figure.
Thats my 2 cents.

This is addressed in the gas codes. You can use hard or soft copper as long as the gas contains less than 0.3 grains of hydrogen sulphide per 100 cubic feet. No compression fittings. No pipe dope on flare fittings.

Nice link, and easy to save a copy for reference! In Michigan, copper tubing is fine, and flex will usually be used for gas [NG or LPG] applications. Flared connections are acceptable and the only type I have observed.

Thanks, Bob. I think I'll send a copy to one our largest plumbing companies. They installed this gas fireplace last year. The seller has really enjoyed it.
