Nominal pressure at the burner for Natural Gas is 3.5" of water column. (Typical machine supply 5"-7") Pipe length must include additional length for all fittings. Add approximately 5 feet of pipe per fitting. Natural Gas Example: A machine with a burner that requires 440,000 BTU would need a 1 -1/4" pipe …
pressure less than 1 1/2 psig; common to use fittings factor 1.5 - equivalent pipe length in table above = pipe length + 50%; pressure drop 0.5 inches water column; specific gravity of natural gas 0.6; One MBH is equivalent to 1000 BTU's per hour (0.29 kW = 0.29 kJ/s); energy content in natural gas 1000 Btu/ft 3 (37.26 MJ/m 3); steel pipes schedule 40
foot line find the size of pipe needed to carry 488.75 CFH. Notice that we barely miss the 1 ¼" pipe. When it comes to gas line sizing, you ALWAYS round up. Therefore the minimum pipe size for these two sections is 1 ½". So to recap, follow this procedure anytime you calculate the gas line size: First, calculate the distance from the meter = CFH
