The regulator reduces the pressure of the propane gas vapor from the pressure in the tank, to the
pressure required for use at the appliances. This reduction in pressure is performed by a two-stage
regulator. Two regulators are used in the same body to reduce the pressure of the propane gas in the
tank for use by the appliances in the recreation vehicle. The regulator seldom requires service, but it
should always be protected from the elements and extremes of hot and cold.
The high pressure regulator (first stage) is used to reduce the pressure to approximately 10 to 13 PSI
before sending it to the low pressure regulator (second stage). This second stage regulator reduces the
pressure further to 11 inches water column, or 6.35 ounces per square inch. The two stages regulator
does not have to work as hard since the second stage receives consistent pressure rather than inlet
pressure which varies. The result is an efficient safer system that helps to eliminate problems such as
freeze up and pilot outage.
