LP Example: A machine with a burner that requires 440,000 BTU would need a 1" pipe for a 20' long run. used. 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.
