“RESIDENTIAL” PROPANE GAS 2 STAGE REGULATION

In many Propane gas line installations, the gas supplier and/or installer will utilize a two stage regulation process where by at the supply tank they will install the first stage gas regulator, which would be at a higher pressure, usually 10 psi. This higher pressure allows for a much longer distance and in a much smaller pipe size. Then within a short distance of the pool heater, usually around 24 inches, they will install a second regulator, which is the second stage, and this would be set at the required inlet pressure of the heater.

“RESIDENTIAL” NATURAL GAS 2 STAGE REGULATION

In many Natural gas line installations, the gas supplier and/or installer may utilize a two stage regulation process where by at the streets main gas supply they will install the first stage gas regulator, which would be at a higher pressure. This higher pressure is usually set at 2 psi or 5 psi and can be for long distances and in a much smaller pipe size. Then within a short distance of the pool heater, generally around 24 inches, they will install a second regulator, which is the second stage. This second stage regulator would be set at the minimum operating pressure for the heater. For “Natural Gas Pentair Pool Heaters” the minimum is 7 inches W.C.
