Factory Installation Requirement: Although Kärcher's accessory table has a general heading referring to field-installed options, this particular conversion is expressly identified as Factory Installed.
Do not advertise this product as a universal, field-installable propane conversion kit. Its individual components, conversion hardware, propane supply requirements, and final burner performance were not independently confirmed.
Safety Note: Natural gas and propane require different fuel system configurations and combustion settings. Conversion and commissioning must follow Kärcher's manufacturer-approved procedures and applicable gas safety requirements. Never supply propane to an unconverted natural gas burner.
