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 fi 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 effi cient LP-Gas operation for the dealer
resulting in less maintenance and fewer
installation call-backs.
With properly selected regulators, the internal
relief valve provides 2 psig / 0.14 bar overpressure
protection as required by NFPA 58.
