Can a Rinnai Tankless Water Heater be converted to a different gas type?

Rinnai offers a limited Field Conversion Program. Kits for converting gas tankless water heaters from natural gas to propane or vice versa are available for most models. Please have your installer or service provider call us at 1-800-621-9419 to find out if your model qualifies and to obtain a detailed step-by-step conversion instruction kit.

These kits are available directly from Rinnai. They will be shipped only after the installer or service provider has contacted Rinnai’s technical support services and consulted one of our technical specialists, to ensure the installer or service provider is qualified to perform the conversion. The Field Conversion Program is available for installed units where the gas type availability has changed. For safety, it’s not approved for use in conversion of non-sold inventory or mobile homes.
