Product Overview
The R0591606 conversion kit is essential when switching a Jandy JXi 260 k BTU heater from natural gas to propane fuel. As detailed in the official installation instructions, the kit replaces the factory orifice and associated components to ensure the correct fuel‐to‐air ratio and safe operation.
