The NEC does not cover the installation of gas pipe.

True, please read the report.
They discuss the 2011 NEC and possible proposals.
I see a TIA in the future. :smile:

First it appears that in place of bonding this product should be banned. Second, the problem of costs comes into play...the responsibility of installing the bond should fall to the contractor that has installed the light weight easily damaged gas piping system, not the electrical contractor.

I must respectfully disagree. It is not clear that with the proper bonding CSST is any more vulnerable to lightning strike than iron pipe. But suppose that it is, that still doesn't mean it should be banned. For example, my understanding is that CSST is more resilient in an earthquake, by being flexible and installed in a way that it is not tightly coupled with the structure. Then it would be a trade off, with CSST possibly a better choice in areas of high seismic risk, and iron pipe possibly a better choice in areas of high lightning risk.don_resqcapt19 said:

I absolutely agree. If this product is that fragile, I sure wouldn't want it run all throughout my house buried in walls and ceilings just waiting for a fault that will cause an explosion. Besides that, it's just plain bad looking coming from the meter and running into the house. It's way too thin to be exposed to the elements the way I've seen it installed.

Wayne,
Don
That is something that I don't really think about here in northern Illinois, but we probably should. I just think it is a very fragile product. Do the plumbing codes have anything like our 300.4 for protection of this product?

Not from what I have seen.
I just ran into some of this product in a steel truss building.
The gas line was snaked up between the ribs of the roof decking like we snake MC cable.
Of course starting in 2008 I will not be able to run electric lines up in the ribs but I guess a gas line is OK.
I am kind of suprised this problem with lightning was not discovered in the testing stages of this product, before it was put into production, does anybody know what they plan to about all the jobs that are not bonded as per there bulletin, I don't know if it should be banned, maybe just taken off the market until all the bugs are worked out

I've yet to see a house explode... anyone else?

No I have not but I believe the number of buildings that did blow up where behind the lawsuit that resulted in the new bonding requirements.

I would really like to see a report on how many actually did, and how they determined it was caused from lightning and CSST.

Follow the link in post #1, I have not looked but I bet all that info is in there. :smile:

I really doubt that any buildings blew up...the current that burned the hole in the line most likely ignited the gas at the same time...no explosion, just fire.
I wonder how much current it takes to melt a hole in the line?

Plumbers love this stuff. It has all but replaced black pipe around here, and from my own observations it's taken over other parts of the country as well.

Peter,
Don
Why would a plumber like it?...it just reduces the manhours required for a project and the demand for plumbers. Same with electricians and MC.

Don that is a very different view point then contractors have out here.
Get in, get out, move on to the next job.
More jobs worked, more money made.

Bob,
Don
I didn't say contractors...I am talking about the worker, but the contractors should feel the same way. If the code requires a more labor intensive installation the job costs more and there should be more profit.

Not sure about the plumbing code, but the installation instructions of the CSST product I have used address protection from puncture. The basic strategy is to keep it 3" from the edge of framing, or to loosely hang the CSST so that if anything pushes on it it can deflect to at least a 3" distance. Where the CSST is constrained close to the edge of framing, you need to protect it with a heavy striker plate or a spiralwound conduit.don_resqcapt19 said:

Here is a picture of the required striker plates from Gastite.
They are quite a bit larger then standard nailplates. They are required to extend past the bottom and top plates at least three inches.
