Why use a twin stage regulator?  

The Twin Stage Regulator starts with the First Stage which reduces the unregulated tank pressure down to a preset 10 PSI. Then the Second Stage regulator will maintain a constant 11" WC pressure. Having a Twin Stage regulator will reduce the possibility of freeze-ups, which often occurs more frequently as the btu/hr demand increases. Also these units are mostly used in RV's to provide enough pressure for all the appliances and its required by Federal code on all RV's to have a Twin Stage Regulator.
