MANUFACTURES INSTALLATION SPECIFICATIONS FOR SAFETY

https://www.gastite.com/downloads/pdfs/gastite_di_guide.pdf

Direct contact between electrically continuous metallic systems and Gastite® yellow CSST is prohibited. Maintain as much isolation/separation as reasonably possible when planning and installing gas piping from other continuous metallic systems. Continuous metallic systems including metallic chimney liners, metallic appliance vents, metallic ducting and piping, and insulated or jacketed electrical wiring and cables.

Also
CSST, should not be installed within a chase or enclosure that houses a metallic chimney liner or appliance vent that protrudes through the roof.

“Consult local building codes as to required
separations for CSST from such continuous metallic systems
including metallic chimney liners, metallic appliance vents,
metallic ducting and piping, and insulated or jacketed
electrical wiring and cables.”

If the building codes are “SILENT” on the separation then it would be no issue for the insulated or jacketed “Nonmetallic” electrical wire and cable to be in contact.

It also states in it’s Design and Installation Guide :
The techniques outlined within this guideline are recommended practice for generic applications. These practices must be reviewed for compliance with all applicable local fuel gas and building codes. **In the event that there is a conflict between this guide and local code, the more stringent requirement will take precedence.

Under warranty in the guide it states:
INSTALLATION REQUIREMENTS

  1. Installation must be performed strictly in accordance with local plumbing and/or building codes, and in accordance with GastiteR/FlashShield™ Design and Installation Guide.

Proof of what we have been saying for years… “Manufacturer trumps Code”.

This only applies to Gastite brand CSST. So now we need to try and determine the manufacturer :roll:

Sorry, but I’m in the camp of “this is a non issue.”

Not saying it is right, but show me one roll of that that is going to have those instructions included. Now for extra points, show me someone that will read them or leave them there so the electrician can read them.

If the product is so problematic maybe they should improve the product.

Yes and the client needs to make an informed decision about this product.

Morning, Jim.
Hope this post finds you well.

Haven’t been to Inspection News as of late. You always provided great information. Happy to see you on this MB.

I concur. Typically tradesmen/women are taught onsite by/through repetitive example or mimicking. Only change in code or installation procedures occurs when instructed to do so.

As to the last of your post. That requires independent failure case study. I highly doubt the manufacturer will self admit their product requires improvement. That would take R&D.

Keep well.
