The LOCHINVAR L100268109 is a liquid propane (LP) conversion kit designed to convert a compatible Knight fire tube boiler from natural gas operation to LP fuel service. This kit provides the necessary components to safely reconfigure the gas train and burner assembly for propane combustion. Licensed HVAC technicians and hydronic heating specialists install this kit during fuel-source changes, typically when a structure transitions from natural gas utility service to on-site propane storage. Proper conversion ensures correct gas pressure regulation, orifice sizing, and burner performance for the new fuel type.
This conversion kit is intended for residential or light commercial hydronic heating applications where a Knight fire tube boiler is already installed and a fuel-source change is required. The kit is matched to the specific burner and gas valve configuration of the target boiler model, making it an OEM-specified solution rather than a universal adapter. Installation should be performed only by a qualified technician familiar with fire tube boiler combustion systems and local fuel-gas codes.
Suitable for use with the Knight Model KH285 Fire Tube Boiler.
This kit must be installed by a licensed HVAC or gas-fitting technician in accordance with local fuel-gas codes and the boiler manufacturer's instructions, including applicable requirements of the IFGC. Shut off all gas supply and electrical power to the boiler before beginning any conversion work. After installation, perform a combustion analysis and leak test on all gas connections before returning the boiler to service. Do not attempt to use this kit on boiler models other than those specified by the manufacturer.
