Hi Delta FlexGas Hydronic Boiler, 302CD-902CD

Although it is possible to convert almost any Hi Delta® unit from natural gas to propane, it does take time. The patented "FlexGas®" system allows the unit to be plumbed for BOTH fuels, switching from operation from one fuel to the other with the turn of a key - without shutting down the unit at all!
