Hi Delta® FlexGas® Hydronic Boiler, 992CD-2342CD

Although it is possible to convert almost any Hi Delta® unit from natural gas to propane, it does take time.  Certain facilities are required to be able to switch from their primary fuel to a backup fuel immediately when conditions demand it.  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!
