Lochinvar L100268109 Lp Conversion Kit KH285 Boiler

Product Description

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.
