The 606 series systems can be purchased in natural gas or propane. While most of these models range in tank capacity from 30 to 50 gallons, there are two high output models with significantly larger capacities.

All of these models, except the two high output systems, have FVIR technology, which is made to help prevent combustion or ignition of vapors around the water heater. Several of the models within this series are designed for and compatible with mobile home units. There are also direct vent models within the 606 series.
