In NYS, CSST must be "bonded," not "grounded," if it is connected to iron gas piping:
"Bonding Jumper - A bare or insulated conductor used to ensure the required electrical conductivity between metal parts required to be electrically connected. Frequently used from a bonding bushing to the service equipment enclosure to provide a path around concentric knockouts in an enclosure wall: also used to bond one raceway to another."
Perhaps Jerry can explain in simple terms the difference between "grounded" and "bonded."
According to the NYS Codes Department, CSST whips to ranges, dryers, and other appliances are exempted.
The problem is that CSST melts if the gas system is stuck by lightening. This is not good.
