csst gas pipe bonding

[boltneck]

7.13.2 CSST. CSST gas piping systems shall be bonded to the electrical service
grounding electrode system at the point where the gas service enters the building.
The bonding jumper shall not be smaller than 6 AWG copper wire or equivalent.

Is the bonding done only one point, where the pipe enters the building?

This building has hard pipe thruout except small sections of CSST flex pipe that was used as "jumpers" between sections of hard pipe.

should these sections be jumped with a bonding jumper, or is the bond on the hard pipe at the entrance sufficient?

All you need to do is bond at the point of entry. Once the gas pipe is bonded anywhere along the length then the csst will be automatically bonded. No need for jumpers. Generally the is always a solid black iron that enters the building and that is what we bond to.

IF I understand you I do not like this installation for personal reasons.

Are you saying black iron to CSST to black iron to CSST to black iron? If so I am not sure if the CSST can be used to bond these sections together so I need to think about this.

Think about it-- If the black iron is bonded then so is the brass fitting that the csst uses to connect to the black iron. If the connector is bonded that is all you need since you do not bond onto the jacket or the csst itself.

I understand the CSST and black iron are bonded. I am just wondering with the lawsuit back in 2007 if the manufactures allow the switching back and forth of materials.
Understand where I am going?

I would bet that they would like to see it 'jumped', for whatever good that would do.

If inspecting this I think that I would like to see what the manufacturer said about this installation.

I am sure the manufacturer would want a wire run to every joint the entire length of the run. They made an inferior product and will do anything to cover their butts.

The fact is the gas code only requires the bond at the point of entry.

Yes, i saw at least one 3' section where CSST was used between two sections of black iron, up over some obstacles to make a easier transition, i suppose.

Found this:

7.13.1 Pipe and Tubing Other Than CSST. Each aboveground portion of a gas piping
system other than CSST that is likely to become energized shall be electrically
continuous and bonded to an effective ground-fault current path. Gas piping other than
CSST shall be considered to be bonded when it is connected to appliances that are
connected to the appliance grounding conductor of the circuit supplying that appliance.

As I stated before I would ask for something from the manufacturer as to how they view this installation.
