Flexible copper as gas line?

Good, then we agree.

Hence my first suggestion to call the AHJ - with the ultility having the juristiction.

I think we're on the same page for the most part. But I'm not sure you understand what I'm saying with regards to copper piping.

Natural gas piping can be copper if allowed by the utility company. This holds true in many parts of CA, however, the appliance must be connected with a "listed appliance connector" attached to the gas-piping and the appliance (there are exceptions to this rule).

Many jurisdictions allow the piping to be connected directly to the appliance - as in the picture provided. The piping in that picture is not an appliance connector. It's connected directly to the appliance.

Jeff, I think he doesn't realize that you live where the earth beneath feet your sometimes moves.

I do understand what you're saying - Copper is allowed in some juristictions.

What I am saying is essentially the same, just from a different perspective that it is NOT allowed in some juristictions.

My original idea was to have OP understand why AHJ needs a call.

Is this

a flexible copper apliance connector?

Yes, Michael I understand the earthquake potential in CA, however the OP is in Texas.
Both have hmmmm... "interesting" RE rules

[Jeffrey R. Pope]

Yes. That is a listed, flexible, copper connector, but I don't believe that it's listed for NG. We use those for the inlet and outlet of the potable water piping of the water heater.

Do you have a link to what's required in CA for gas?

[Jeffrey R. Pope]

I don't have any links, only the code books. Do you have a specific question?

[Jack L. Gilleland]

The gas line is bottle necked. The appliance should have full size from the female on the input to the WH to the gas line.

Most gas suppliers want a drip leg before the flexible connection and most don't want soft copper. When the line is looped (as in your picture) the dirt leg is created at the bottom of the loop.

Just trying to figure out what the listed, flexible appliance connector (copper) for gas in CA looks like.

[Jack L. Gilleland]

Different AHJ in CA actually all over US have different approved connections. This is just one.

[rmaday]

Looks like CSST - seen that, never seen the copper.

[Jack L. Gilleland]

Don't have any pics of copper only and the one that I do have is a copper over stainless and that doesn't carry the approval stamps for CA. Your also have to pay attention to the length, most jurisdictions approve these flex connectors for only limited lengths.

[Christopher Currins]

Here is a link that might help..

DING DING DING!

I think a light bulb went off in my head.
1) The supply may be copper (if gas co approves)
2) The "listed, flexible appliance connector" you've referenced is not necessarily copper.
How am I doing so far?

If the above two statements are correct, my confusion was in thinking you meant the "listed, flexible appliance connector" was also copper.

My question is, Is there such a listed, flexible appliance connector that is indeed copper?

I'm not sure I've ever seen a copper appliance connector, listed for use with NG. I've seen brass, but most are stainless steel.

The copper-flex you posted is typically listed for water only.

Sorry for the delayed responses. I'm working today and posting between inspections.
