Lochinvar L100318503 Burner Manifold Gasket

Product Description

The LOCHINVAR L100318503 is a burner manifold gasket designed to seal the joint between the burner manifold and the combustion assembly in gas-fired heating equipment. This gasket prevents combustion gas leakage at the manifold interface, maintaining proper draft, combustion efficiency, and safe operation. It is a direct OEM-style replacement component installed by licensed HVAC technicians and plumbers servicing Lochinvar boilers and water heaters. Replacing a degraded or damaged manifold gasket restores the sealed combustion path and is a standard step in burner section servicing or heat exchanger access procedures.

This burner manifold gasket is suited for use in residential and light commercial gas-fired systems where the burner manifold requires resealing during routine maintenance, burner replacement, or after heat exchanger inspection. It is commonly installed during scheduled service intervals or when combustion gas leakage is detected at the manifold joint. Technicians working on Lochinvar boilers and water heaters should verify the specific unit model against Lochinvar service documentation before installation.
