| Gas pressure to the building (outside) is normally 10 psi. At the building it is reduced to 11 inch water column (WC). Size pipe accordingly but I would say you will need minimum 1" pipe and not very long in length. May talk to your LP supplier about a 2 lb system inside the building which would reduce pipe size requirements, but will require additional regulators at each appliance. LP appliances operate at 11" WC which is approximately 1/2 lb. | |
