Lochinvar & A.O. Smith 100190886 Gasket Kit
As a field technician, you know that a compromised seal on a high-capacity boiler can lead to immediate pressure loss and efficiency drops. This Lochinvar & A.O. Smith 100190886 Gasket Kit is the specific OEM solution required to restore the integrity of the manifold assembly. Designed specifically for the FBN/L 2500-3500 commercial heating boilers, this kit replaces the legacy part number GKT30024. The high-temperature resistant materials are engineered to withstand the extreme cycling and thermal stresses common in heavy-duty hydronic systems. By utilizing this genuine Lochinvar replacement part, you ensure a precise mechanical fit that prevents combustion gas bypass and water leaks at the manifold interface. For any contractor performing a 100,000-cycle teardown or routine manifold maintenance, having this HVAC manifold gasket kit on hand is critical to avoiding a second truck roll. This OEM manifold seal provides the exact tolerances required by the manufacturer to maintain the boiler’s UL listing and peak firing rate.
Key Benefits
- Specifically engineered for Lochinvar FBN/L 2500-3500 series boilers to ensure a factory-standard seal.
- Direct replacement for part 100190886 and legacy number GKT30024 for seamless compatibility.
- Constructed from heavy-duty, high-temperature composite materials to prevent manifold air leaks.
- Complete gasket service kit includes the necessary components to reseal the manifold during heat exchanger maintenance.
- OEM-spec thickness and compressibility ensure reliable performance under high atmospheric pressure.
Common Questions
When should the manifold gasket be replaced on a Lochinvar boiler?
Technicians should replace the gasket whenever the burner or manifold is removed for inspection. Over time, heat cycles cause the material to lose its elasticity, and reusing search gaskets often leads to "whistling" or combustion gas leakage.
Does this kit include more than one gasket?
Yes, as a manifold gasket kit, it typically contains the primary sealing components required to reassemble the manifold to the heat exchanger interface for the specific FBN/L boiler frame sizes mentioned.
Can I use RTV silicone instead of the 100190886 gasket?
No. These high-output boilers require a specific OEM manifold gasket with a determined thickness to maintain the correct gap for combustion. Substituting with liquid sealants can lead to hazardous operation or component failure.
