Rheem Richmond Commercial Conversion Chip (Old Version)

The Rheem/Richmond RTG20224B Commercial Conversion Chip (Old Version) is a tankless commercial conversion kit used to enable compatible direct-vent tankless units to operate in commercial mode (commercial programming/controls), providing the proper OEM components for a correct retrofit. It’s the straightforward, factory-intended way to make the unit behave like it belongs in a commercial application—without relying on “close enough” settings.
