Failed inspection--CSST flexible gas line

I know this has been discussed before, but I thought I'd bring it up again.

I had a kitchen remodel fail an inspection today because of a rule I'd never heard of. I'm curious to know if this is being enforced more and more across the country (or being banned altogether). I've had flexible gas line installed on a number of projects and this is the first time this has ever been brought up by an inspector.

He claimed the new rule is that any flexible gas line must have a minimum 2" clearance from any metal duct work, conduit or electrical line. The reasoning behind the rule being that in the event of a lightning strike, current can arc through the thin wall gas line and cause an explosion. He did not, however, mention any grounding requirement---which as I've researched this more surprises me.

My plumber called in to the local union heads and it's my understanding this is a rule they have only just begun to enforce here in Indy.

Sounds like he's talking about
the new "bonding" requirements.
Everyone seems too sketchy for me,
I'm just going with black pipe til
everyone is telling me the same story.

I still use mostly black pipe and copper with flare fittings.
I had all the stuff in flex to do a kitchen and chickened out and installed pipe up through the floor, my gas guy was cool with that
A bump to a another thread related to CSST...

I may be switching to hard pipe for the time being as well.

Ok then, isn't that gas supply on the back of most ranges a flexible tubing like what you are talking about. That is ok but, not for coming through the floor? Hard line through, then to the flex for the range whip? Seems that does not make much sense either.
sleeve it in pvc pipe where needed
Sleeving doesn't matter according to my inspector. 2" minimum from any continuous metal, period.

Apparently this was part of 2005 code amendments--but the inspectors in my area have only recently been through CSST training to enforce it.

New code changes or additions always bring problems with them

Every Code in the UPC states "Up to the administrator authority" the inspector.
You can try and fight with some of these bozo's which will hold up your project or just correct it.

I had one in San Diego ask for some lame as #!^$, just did it and moved on.
Try to use hard pipe as much as possible. There are situations, when it gas flex is clearly the best option, but, it's a good idea to use hard pipe. Less headaches, and, it looks more professional.
This thread is older than my daughter but.....still relevant. My plumber switched me over to black pipe for pretty much everything. As he put it, "It would take a much dumber a$$hole to put a screw through this than through a piece of flex".
We just had one a few weeks back, the inspector says the pass thru on any wood member must be double the pipe size if using CSST
