CSST should not pass through the cabinet, however, I see it this way all of the time.
The IRC and most local jurisdictions don't have many regulations with regards to CSST other than deferring to manufacturers recommendations.

A grommet or sleeve is required to protect the CSST against abrasion.

Here is what many local jurisdictions are requiring for new construction.
This eliminates the need for shielding of the CSST.

I cannot remember which manufacturer it was, but there is one that instructs you to install csst in the cabinet because of the configuration of the equipment on one particular model. I will try to look it up again and get back with you on the brand and model

Hey Jeff; Check out one of the prior Uniform Mechanical Codes on this
particular subject. I got dinged on a flex connector through drywall
about two years ago by the Gas Company. The plumbing contractor
left a copy of the code with the bill. It basically states any flexible gas supply connector and or plumbing may not be run though anything
other than open air space. It made no mention of being acceptable
with sleeve protection.

To the best of my recollection (and I’ll double check that), it is not allowed to pass through walls and is only allowed for interior use.
Passing through an appliance cabinet is where the sleeve or grommet is required.
Everything I can find with regards to the UPC and UMC defers to local jurisdiction and manufacturers recommendations.

Does this address it?
Code Check "A field guide to building a safe house"
Page #21, Mechanical: Gas: Gas Connectors: item 3:
"Not pass through bldg. or appliance wall" (IRC 2421.1.2) (UPC 1212.2)
I don't have a mechanical code at home, I'll check it out and report
back when I get to the Library.
Have a great week guys!

Appliance connectors may not pass through walls and/or floors. Appliance connectors must be installed at the appliance in accordance with the appliance manufacturer.
Appliance connectors are usually short lengths (< 4' ) with an inside dimension (ID) of 1/4" typically.
CSST, when installed as gas piping, is long lengths typically with an ID of 3/8" or greater. Steel piping is used for the transition from the gas line to the appliance connector.
Will, UPC 1212.2 deals with gas connectors or appliance connectors.
I was forced to make the call today when I found this in a condo built in 2003.
It's difficult to tell from the plaster coating, but these are all CSST lines passing up through the floor from the garage.

Jeff,
If CSST is only for interior use, what is to be used on the exterior? steel? copper?
I'm going to have to look into this further. In my local area, I've seen many applications where the CSST was run from the LP tank outside directly through the wall and into an appliance and/or through a masonry fireplace right into the fireplace for a gas log or gas insert.

It can be run exterior and buried as long as its in a protective pipe/
conduit. Run a Google search on csst manufacturers, a host of
information is available on uses and installations. I was originally commenting on the photo in the first post. I think we all agree csst
and or any other flex connectors may not pass through an appliance
wall as shown in the photo, (Unsafe Condition). Jeff is correct in that
rigid pipe must be used when passing through the appliance wall as
shown in his photos.

Is that a wall furnace? Code allows gas flex to be inside wall furnace access panel.

"Code" does not address that condition. The appliance manufacture may allow it.

I know local codes prevail, and the manufacturer may allow it. My code check book states that it may be installed INSIDE access door of a wall furnace. I see it all the time, and it is allowed in all cities and counties in my area.

I assume you’re referring to the UPC or UMC as you are in CA.
I did research this and went as far as calling the Building and Safety Department. If you can provide me with the code section and reference, I would greatly appreciate it.

Hi Joe; Maybe were talking about different issues. I also find flex in
use at the interior service area of wall furnaces, but the run into the compartment and or through the floor to the unit is rigid pipe. The verbiage I’ve seen in the IRC, UPC, UMC and or Code Check only
addresses the issue of flexible gas connectors running through an appliance “WALL” as being an unsafe condition.

Will,
I was just commenting on what I saw in the picture in Heath John’s post that started the thread. I didn’t see the flex going through a cabinet anywhere in the pic.

Has a lot of wiring in it for wall furnace, but your right, I don’t see it
passing through the appliance wall either. Let’s ask Heath. If your getting
these responses Heath, is it a FAU or a Wall Heater and does the gas connector pass through the appliance wall?
Have a Great Weekend Guys...

I think the confusion here is the difference between CSST and flex appliance connectors. They are different, although they look similar.
Flex connectors are installed per manufacturers recommendations.
CSST, as gas piping, is installed per the UBC (in CA).
