The LOCHINVAR L100287090 is a burner gasket designed to seal the burner assembly in commercial and residential hydronic heating equipment. Burner gaskets prevent combustion gas leakage at the burner-to-heat exchanger or burner-to-combustion chamber interface, maintaining safe and efficient system operation. This is an OEM-specified replacement part intended for installation by licensed HVAC technicians or qualified heating system service professionals during routine maintenance or burner service calls.
This gasket is suited for use in boiler and water heater applications where burner compartment integrity is required. It is typically replaced during burner inspections, heat exchanger service, or whenever the original gasket shows signs of compression failure, cracking, or combustion gas bypassing. Installers working on LOCHINVAR equipment will recognize this as a direct factory replacement component.
Designed as an OEM-style replacement burner gasket for LOCHINVAR commercial and residential boiler and water heating equipment. Consult the equipment service manual or LOCHINVAR parts documentation to confirm fitment for a specific unit model before ordering.
Installation should be performed by a licensed HVAC or boiler technician familiar with combustion system service. Before replacing the burner gasket, shut down the appliance, isolate the gas supply, and allow the burner and heat exchanger components to cool completely. Inspect the mating surfaces for warping, corrosion, or debris before seating the new gasket. Follow the manufacturer service documentation and applicable codes, including the IFGC, for reassembly and post-service leak verification.
