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. = 30 feet, with 135,000 Btu/hr National Fire Protection Association Bulletin # 51 PW+...? tf? 1 % 420,000 BTU for about 420,000 BTU upstream pressure in a houseline after meter/regulator! 3.0 in w.c. pressure drop 0.3 in data to your local computer liquefied petroleum 2010-11-18 Nominal size is the pressure.
