Sizing Natural Gas and LP Propane Gas Pipe- Longest Length Method! IFGC 2015

In this HVAC Gas Line video, I show you how to Size Natural Gas and Propane Pipes using the IFGC 2015 to determine the minimum pipe size diameter for an entire building worth of gas lines. I go over why we use the procedures and methods shown in the video. I show you how to determine the correct sizing chart for the application as there are many charts to choose from in the International Fuel Gas Code Book. The equivalent length of all fittings more than four total must also be used as well when determining the longest length of the piping section.
