Lochinvar L100190132 Burner Gasket Kit Boiler

Product Description

The LOCHINVAR L100190132 is a burner gasket kit designed to seal the burner assembly on high-output commercial heating boilers. Gasket integrity is critical to safe and efficient combustion — a failed or compressed burner gasket can allow flue gas bypass, reduce combustion efficiency, and create unsafe operating conditions. This kit provides the replacement sealing components needed to restore a proper gas-tight burner seal during scheduled maintenance or after a burner removal. Installation is performed by licensed HVAC technicians or qualified boiler service professionals familiar with commercial heating equipment.

This gasket kit is specified for use with the Crest Model FB(N,L)3000 to 3500 heating boiler series. It is appropriate for service work on both natural gas and propane-fired configurations within that model range. Technicians performing annual burner inspections, combustion testing, or burner replacement on applicable Crest boilers should use this OEM kit to ensure proper sealing material and fitment.

Installation Notes

Installation should be performed by a licensed HVAC or boiler technician. Before beginning work, shut down the boiler, close all gas supply valves, and allow the unit to cool completely. Remove and discard the old gasket material before seating the new gasket — do not stack or reuse old gaskets. Work should conform to local mechanical codes and the boiler manufacturer's service documentation.
