Where in the 2011 NEC is bonding of CSST addressed and where in the 2011 NEC is Grounding of CSST addressed?
If it (CSST) is connected to an appliance that is connected to the equipment grounding conductor that supplies the appliance, do you still have to run the #6 back? I think the fuel gas code has something like that stated. Do manufacturers instructions supersede IFGC?
Manufacturers instructions that are part of the listing must be complied with. The CSST in all cases must be bonded with more than the egc except for the CSST called counterstrike made by Omegaflex. There may be others but counterstrike does not require additional bonding. Of course, I don't trust the stuff so I bond it anyway.
That is fine for black iron pipe or non csst. CSST we enter a new world with new rules.I guess with gas I wouldn't either...I have seen some installed that depended on the stove ground. Just curious about your thoughts...

bonding of csst piping is in the 2009 fuel gas code 310.1 and the 2009 international residential building code g2411.1.1, not in the 2011 NEC
This is true and the 2011 now has an informational note Number 2 in art. 104(B) directing us to the 2009 Fuel and Gas Code Section 7.13
This piping is dangerous. If you are the one bonding it make sure your insurance is paid up!
2 millions homes with this csst piping installed and they are very worried about it.
The csst pipe acts as an antenna with lightning and burns holes in the pipe.
they now have a new pipe with shielding and semi?conductive
polymer jackets

If this was in my house I would rip it out.
Nothing wrong with it but it is alot more costly to install. I try to get the builders to not use it but to no avail. we seem to be ultimately responsible. FWIW, I do bond the counterstrike, by Omegaflex, even though they say you don't have to.
I wired a 7,000 sq. ft house that had burned down. The cost of the job was going to be around 2-3 million. The HVAC guys show up and start running CSST until I stopped them. I said you better speak with the HO as I knew she would not go for it. I am sure that job cost more but I know the HO is sleeping better at night.
Electricians wil also take the easier road so why shouldn't they. Many are not as aware as we are of the problems with the product. What amazes me is that the agencies involved have not stopped it.
Only time will tell. If fires strike with the bonding on then that will be a telling sign. Of course the reverse will be hard to tell until all the piping is bonded.I still don't get what good a bonding jumper around this piping does?
