Lochinvar & A.O. Smith 100287090 Gasket
The Lochinvar & A.O. Smith 100287090 Gasket is a critical OEM replacement part designed for high-efficiency condensing boilers and water heaters. This 4MM X 121MM OD Burner Gasket provides a high-temperature seal between the burner assembly and the combustion chamber, preventing volatile combustion gases from escaping the heat exchanger. Engineered for precise fitment in Lochinvar Knight and A.O. Smith commercial units, including the KHB199, KHB285, WHB199, and WHB285 series, this gasket maintains the thermal integrity required for condensing operation. Technicians should inspect this component during every annual burner service, as a compromised burner flange gasket can lead to improper CO2 readings and reduced combustion efficiency. Effectively replacing your Lochinvar 100287090 ensures a gas-tight seal, safeguarding the internal components of the heating system from heat damage. This genuine boiler burner gasket is the direct substitute for legacy part numbers 100209442 and GKT20198.
Key Benefits
- Precision Engineering: The 121mm outer diameter and 4mm thickness ensure a perfect fit for KHB and WHB burner assemblies.
- High-Temperature Resistance: Constructed to withstand the intense thermal cycles of modulating condensing boilers.
- Combustion Integrity: Prevents bypass of combustion air, ensuring optimal burner performance and stable flame signals.
- Direct OEM Match: Eliminates compatibility issues common with universal aftermarket seals in Lochinvar heating equipment.
Common Questions
Which models are compatible with the 100287090 burner gasket?
This gasket is specifically designed for Lochinvar Knight and A.O. Smith models in the 199,000 to 285,000 BTU range, including the KHB/KBN 199-285 and WHB/WHN 199-285 series.
Does this part replace older Lochinvar gasket numbers?
Yes, the Lochinvar 100287090 is the current manufacturer-approved replacement for part numbers 100209442 and GKT20198.
Why is it necessary to replace the burner gasket during maintenance?
The gasket compresses over time and can degrade due to high operating temperatures. Replacing it ensures the combustion chamber seal remains intact, preventing hazardous leaks and maintaining AEO-ranked energy efficiency.
