Good document, shows various ways to bond, counterstrike upgraded pipe, use of “gas breakers” etc.
The only unclear thing is their baseline setup, which they say gets bonded through the equip. gnd wire but they do not elaborate on exactly where that is done. Relying on a ground through equiment parts like the furnace gas valve and furnace cabinet sounds dumb to me when trying to bond something as important as CSST.
They show setup choices as baseline, good, better and best.
