I'll be installing a ventless gas heater. It's about 10 feet away from a former 3/4" stove connection. The connection needs to go through an area of the ceiling that is inaccessible, and would be very difficult to run black pipe. I plan to use CSST. I'm trying to figure out the electrical bonding requirements. This gas connection would be at the far end of the house from the gas meter, but close(ish) to the main grounding rod. If I understand correctly, it's acceptable to run a 6 AWG copper ground from the CSST fitting to the main electrical ground. Do I also need to bond the end of the iron pipe run to the CSST fitting? I don't think the gas meter or anything is directly bonded to the grounding rod or the water pipes (also inaccessible until they enter the basement). Anything else I'm missing?
