Once you know the total footage from the meter to the end of one of the branches, use the next highest footage column in the medium pressure chart, (are you sure the house is medium pressure? Normally it would be low pressure unless there were some special conditions). At any given branch point add up the total BTU's past it and find the next highest entry in the chart. That will be the pipe size to that point. Keep going until you get to the end of that run and then repeat the process for any other discrete branches if there are any. : terry, i need some help on refreshing my memory : i,m having a problem on trying to size a res. gas system. i have the 2001 code book and know the chart to use. i have an iso. drawing,length and cfh for each appliance but can't seem to put it all together with the chart to size it correctly . i was wondering if you could give me an idiot proof way of getting me through this. any help? thanks jim the tune "follow" was pretty cool.
