Converting your existing heating system to operate on liquid propane is streamlined with the 383-500-120 conversion kit. This authentic Weil-McLain component package provides all the necessary hardware to modify your boiler for alternate fuel compatibility, ensuring the system maintains its original factory performance standards.

This conversion kit utilizes precision-engineered orifices and calibrated components to adjust gas pressure and air-to-fuel ratios, allowing the boiler's combustion chamber to ignite and maintain a steady flame when fueled by propane. Proper installation is critical to ensure that the combustion cycle remains clean, efficient, and within the safety parameters specified by the manufacturer for propane operation.

Key System Performance Baselines:

  • Fuel Compatibility: Specifically engineered for natural gas to liquid propane (LP) system transitions.
  • Precise Calibration: Includes OEM-specified components to maintain optimal BTU input levels.
  • Factory Compliance: Designed to meet rigid Weil-McLain safety and performance standards post-conversion.

⚠️ Application Profile: This kit is intended for residential or light commercial Weil-McLain boiler models that require a fuel source change due to gas utility limitations or local site requirements. Installation must be performed by a qualified HVAC technician to ensure proper gas pressure verification and system testing.
