TL;DR
CSST bonding is the connection of corrugated stainless steel gas tubing to the building's grounding electrode system with a clamp and conductor of at least 6 AWG copper, attached to a rigid pipe segment near where the gas line enters. Lightning striking nearby can induce voltage differences that arc through the tubing's thin wall, perforating it and igniting gas, the failure that drove manufacturer instructions and fuel gas codes to mandate this measure for yellow-jacketed product.
What it means
CSST bonding is the connection of corrugated stainless steel gas tubing to the building's grounding electrode system with a clamp and conductor of at least 6 AWG copper, attached to a rigid pipe segment near where the gas line enters. Lightning striking nearby can induce voltage differences that arc through the tubing's thin wall, perforating it and igniting gas, the failure that drove manufacturer instructions and fuel gas codes to mandate this measure for yellow-jacketed product. Electricians and inspectors check for it in homes built or re-piped since the mid-2000s, and retrofitting it is an inexpensive safety upgrade.
