Jim,
So, if the house has black steel entrance piping, with one section of CSST coming off the drop to the furnace and it runs over to the only pre-manuf fireplace, the system is properly bonded if the main steel gas line is bonded back to the main electrical panel (service equip)? Can the main steel gas line be jumpered over to the main water line ground connection point?
