Lochinvar L100190481 Burner Gasket Kit Crest Boiler

Product Description

The LOCHINVAR L100190481 is a burner gasket kit designed to seal the burner assembly in high-efficiency condensing heating boilers. Gasket integrity is critical to combustion safety and system efficiency — a compromised burner seal can allow flue gas leakage, disrupt the combustion chamber pressure boundary, and trigger lockout conditions. This kit provides the correct OEM-specified gasket components needed to restore a proper seal during burner service or replacement. It is installed by licensed heating technicians and plumbers working on commercial or residential hydronic heating systems.

This gasket kit is specified for the Crest Model FB(N/L)FB3000 to 3500 heating boiler line. These are large-capacity condensing boilers commonly found in commercial and light-industrial hydronic heating applications. The kit is used during scheduled maintenance, burner removal, or any service event that requires breaking the burner seal. Using the correct OEM gasket ensures the combustion chamber returns to factory-specified sealing conditions after service.

Installation Notes

Installation should be performed by a licensed heating technician or qualified service professional. Before servicing the burner assembly, shut down the boiler, isolate gas supply per local codes, and allow the unit to cool completely. Old gasket material should be fully removed and mating surfaces inspected and cleaned before seating the new gasket. Follow the boiler manufacturer's service documentation and applicable codes including the IFGC for gas appliance service procedures.
