Is this csst

[John Evans]

Some manufacturers of Corrugated Stainless Steel Tubing (CSST) were involved in a class action lawsuit for CSST installed prior to 09/06. There apparently have been some cases when lightning damaged residential CSST.
Additional bonding requirements have been required after Sept. 2006. I have seen this product placed through unprotected sheet metal openings in gas fireplaces and the vinyl jacket was shredded.

Will some one explain the importance of the vinyl jacket to me.
Thanks.
Also why do you think it is more of a lightning draw than say black pipe.

Bob,
Some good CSST bonding information on the attached web site. The CSST lightning damage coccured as a result of the thin wall make up of the CSST.
Pin holes were discovered in some of the damaged CSST. In addition to improved bonding standards, I beleive the new CSST is constructed with heavier walls. I do provide information regarding the potential CSST issues within my report when I inspect homes with this product installed prior to Sept. 2006.

Not more of a draw, just more susceptible to damage. . .

Thanks that was what I was wondering.
What about the vinyl coating?
Is that just to insulate in the walls? (from electric arcs )?
