What do you bond Csst to? One clamp goes on the piping, then the wire goes from that clamp to where?

from the internet.
"That means that the bonding conductor for CSST can be connected to the metallic water piping coming into the home, a ground rod at the exterior, or anywhere else on the service grounding electrode system. This change makes it much easier to properly bond CSST.Nov 22, 2016".

So if I’m reading that right, One clamp on the gas pipe, and the other end clamped to copper water line?

yes - assuming the copper is, itself, properly bonded to ground

" the metallic water piping coming into the home"
not to any old water pipe.

The clamp attaches to a steel/brass nipple or fitting, not to the flexible tubing. The other end connects to the
electrical service grounding system. The only part of an interior metallic water pipe that can be used as part of the electrical service grounding system is the first 5 feet of it that enters the structure. Check the Article 250 of the NEC for what is considered the electrical service grounding system.

lots of good examples here.. [www.google.com]

Are you guy's really still using the yellow stuff !!!!

TracPipe's (Black rubber coated) CounterStrike csst Put an end to Bonding 15 years ago.(Grounding).

all I use is the black coated CSST. no bonding needed.

As other posters have said, the newer CSST lines have a faraday cage webbing embedded into the outer coating (now typically black, distinguishing it from non shielded CSST). The bond webbing is similar in principal to the braid found in coaxial cable.

In my area, I've never seen this newer type of CSST sold in big box stores like Lowe's or Home Depot.

I'd rather go through whatever it takes to hard pipe gas than use CSST.... too many lawsuits, too many reports of properly bonded, professionally installed CSST still blowing holes, too many windmills on the hill. Signed, Quixote.

In answer to your question, does the manufacturer of the CSST you are using have a website? Since there are several different manufacturers of CSST, each with patent protected proprietary connector and installation idiosyncrasies, that would be where I'd look first, even if I had to call the company, where no online literature is available.

When I at one time was considering a CSST installation, the manufacturer recommended bonding at the connectors only, never the tubing itself. My jurisdiction required a 6AWG bare copper bond wire between the gas line connector and the water piping connected to the appliance (water heater) being served.

This doesn't answer for CSST fed fireplace inserts, where no water piping is present. Or what is done when water pipes are all PEX. If not hiring a licensed HVAC/Plumbing professional trained in gas, then the amount of research and study of the best practices needed for a safe installation is beyond the scope of anything I've ever read in a plumbing forum.
