Who normally does the bonding on a gas service. I was trying to determine whether to ground and bond the csst service inside my house to the electrical panel ground, or whether it should be bonded to the meter instead. Unless I have missed it, it doesn't appear to have been ground and bonded anywhere, this includes at the gas meter itself. I wanted to run natural gas to an outdoor grill, but I was unsure of the grounding requirements.

In my jurisdiction, the NEC is followed which requires bonding of the gas system to the building ground. The gas bond connection must be prior to the first branch of CSST (onto the steel portion of the gas system).

where i am (Louisiana), csst is not an outdoor or buried usable material. sdr11, galvanized, copper or coated black iron would be a legal material to run to a grill. copper is the simplest for a small application such as a grill unless it is an expensive model that is a gas hog. sdr11 would be my choice in larger diameter applications.

tracpipe counterstrike does not need to be grounded..

i bury it in 1 1/2" PVC. to make the ends watertight i use those rubber end caps. just drill a hole in it slightly smaller than the OD of the CSST and slide it down onto the PVC and tighten the clamp.

This will be going through an exterior wall onto a deck, encased in conduit for protection against damage.
