We are doing a build out of an outbuilding for my company's workshop. Last spring we had the propane supplier upsize the propane pig to handle the expected increased usage and set it up so that a second line could be run to service the shop for heat and a tankless water heater (approx. 280,000 peak BTUs over 50 feet after secondary regulator including 8' up to a second floor for drops from above.
They stubbed out with a gas cock off of a tee for the 2nd line.
We are planning to have the underground line run before winter and I noticed that the supplier set up the second supply outlet on the tank with 3/8" copper mimicking the one that currently serves the single propane appliance house. I was planning to have the underground supply line to the building be 1/2" or 3/4". The main trunk line in building after the secondary regulator is apparently going to be 1 1/4" black iron.
My question is whether that 3/8 line is standard from the first stage regulator. Can it be tied into a 3/4" underground riser to adequately supply the system?
Thanks. Just trying to understand everything ahead of the scheduled trenching and hook up. Where we are located out in the sticks it can take a month or more to even get the propane provider on site.
