Why Choose the OEM Conversion Kit?
Using the factory-authorized Weil McLain conversion kit ensures your CGi boiler maintains its performance ratings and warranty compliance after the fuel changeover. Third-party or improvised conversions risk improper combustion, reduced efficiency, and potential safety hazards. The 510-811-266 kit is purpose-built to deliver the correct LP orifice sizing and regulator settings for the CGi boiler platform.
Installation Note
Fuel conversion must be performed by a licensed and qualified heating technician in accordance with local codes, the boiler manufacturer’s instructions, and applicable gas safety standards. Always verify compatibility with the specific CGi boiler model prior to installation.
