bonding of gas lines

In my area "Northern Virginia" it is not the practice to bond the gas line to the electrical system except by the ground in the wire providing voltage to a gas unit. This is permissible in 250.104(B). The issue I'm having is that a home inspector is stating that the gas line must be bonded to the service and water lines. In our area this is not done! and in fact, the gas company if they find this bonding wire will remove it. What is the general consensus of bonding the gas line?
Thanx
 
What type of gas line riged, or CSST. there is a tread for the CSST.

NFPA 54 will give guidance on the Gas standard.

If the line is CSST then the manufactures instruction need to be consulted but in this area thats the plumbers responsibility.

Is Virginia still under NEC 2002?
2005 250.104 (b) says you have to bond it to the system.
Oops! After further review: The NEC allows the egc of the circuit likely to energize the gas piping to serve as the bonding means.
The home inspector is wrong.

We are required to bond the gas piping independently here in Tucson. Virtually all of our furnaces are plug and cord, which would offer no bonding if it were unplugged.

Are the furnaces designed for cord and plug connection?

Do the manufactures installation instructions allow cord and plug connection?

I have never seen a standard furnace that is designed and identified for cord and plug connection.

In our area, you have three or four different inputs.
(a) the gas company's jurisdiction stops at the gas meter and they have little to say about "bonding" INTERIOR piping.
(b) The current mechanical & electrical Codes in effect here both require
bonding of interior piping.
(c) The installers of CSST now say their instructions require a seperate bond from the gas manifold to the grounding electrtode conductor.

Its the new wave, all the newer german boilers I've wired are cord and plug connected, kinda cool actually.

Interesting, I have never seen a furnace, or boiler that was identifed for cord and plug connection.

I didnt install it, it came with the product.... The last one I did was a Canadian brand Viessmann, Pretty slick unit. The only problem I had wiring it was the supply house that supplied it, gave the plumber a ton of extra parts that I didnt need, I had to do ALOT of reading as well... probably a days worth.

We have had to start bonding the gas line independently with #6 or # 4 just recently. The yellow flexible gas line.

It has been in the NEC, but not enforced until recently.
It came up because of something to do with lightning.

Bonding CSST is not a code requirement. At least not a NEC requirement, I dont do it unless I'm getting paid extra for it.
 
We used to do that here in NJ but when the gas company came in they removed the ground strap. It's been several years now that the head of code interpretations in NJ has put a stop to that.

I remember several years ago Mike Holt published an article (I believe it was regarding a problem in San Antonio, TX) where the grounding of the gas lines was creating a pipe corrosion problem throughout the muincipality. Anyone have access to that article ?

We are not to use water pipe as ground because they think it makes copper deteriorate an turn toilets green inside, and all the new plumbing in this area is going to pex anyway, we also do not bond to the gas lines..

This is how rumors get started.

This statement will turn into the next guy saying he read it somewhere and the next guy after that will say he saw it in the code and so on.

Unfortunately it is just plain untrue.

I invoke Charlie's Rule. I can't find the exact wording though and can't quote it from memory.

[edit: here's an approximation?]

This requirement comes from the CSST manufactures installation instructions.
