lP-gas RegulaToRs 17.2 bar and deliver a constant outlet pressure of LP-Gas typically at 11 inches w.c. / 27 mbar to consuming appliances. The regulator must deliver this pressure despite the intermittent use of the appliances. In propane service, NFPA 58 requires Two-Stage regulation on all xed piping systems that serve 14 inches w.c. / 35 mbar appliance systems (normally operated at 11 inches w.c. / 27 mbar pressure). Two-Stage regulation produces a nearly constant pressure to the appliance and can result in a more efcient LP-Gas operation for the dealer resulting in less maintenance and...
