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. 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!
