Hi Delta® FlexGas® Water Heaters, 302CD-902CD

Although it is possible to convert almost any Hi Delta® unit from natural gas to propane, it does take some 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 to BOTH fuels,switching from operation on one fuel to the other with the turn of a key-- without shutting down the unit at all!
