The first goal of determining the pipe sizing for a fuel gas piping system is to make sure that there is sufficient gas pressure at the inlet to each appliance.The majority of systems are residential and the appliances will all have the same, or nearly the same, requirement for minimum gas pressure at the appliance inlet. Of course there's nothing wrong with oversizing the piping, so if 1" pipe makes you feel better then go for that. Natural Gas flow is given in thousands of BTU/hr. 0
