Re: LP bonding
Well, bonding gas piping is only required where it is "likely to become energized". It doesn't sound to me like it is, so I wouldn't bond it at all.

Re: LP bonding
NFPA 54 or 58. I think 54 is the natural fuel and Gas Code and 58 is LP.
I don't have either at home .
Im pretty sure the LP Code does not require or want the piping bonded BUT PLEASE CHECK TO BE SURE!!
The Naturel Fuel and Gas does require the interior gas piping to be bonded I think it states upstream from the appliance shut off. (try section 3.15, but again no book). See NEC 250.104 (B). If my memory is off pleas accept my apoligy.
and please check NFPA 58.

Re: LP bonding
Would you want the gas company picking apart your work because they don't think it looks right? As for the bonding as Ryan said likely to become energized I think is the key phrase. If it is connected to an appliance that also utilizes electricity than it could possibly become energized. The EGC that serves that appliance would provide the bond as required by the NEC and no further bonding would be required.

Re: LP bonding
I agree that stuff can look shabby. The integrity is within the stainless flex. The yellow covering always makes it appear kinked on bends and it seems impossible to get a nice straight run. The fun part is the plumbers trying to fish it in. Ever see a plumber use a fish tape?

Re: LP bonding
I don't think you can kink that stuff. The kink is in the yellow plastic jacket. So the gas installers, gc, and inspectors are fine with it. The electrician isn't. Hmmm. How much experience do you have with it?

Re: LP bonding
AllenWayne,
Are you in an area that requires the gas to be bonded to be sized by 250.66?

Re: LP bonding
Bob,the way we are required to bond to gas system depends on jurisdiction.We deal with 4 different ones each require something different than each other In this case we have to have a #8 min. requirement That can come from the panel or from a seperate connection on ground rod.In this area we have a #4 from embedded concrete footer and 1 ground rod requirement.There has to be a seperate connection from ground rod or if from from panel we can use factory neutral bar or ground bar if split service

Re: LP bonding
Also meant to add go 1 mile across the county line and we have to size in accordance with the largest branch circuit grounding condutor that can be installed.
