Lochinvar & A.O. Smith 100233643 Gasket
The Lochinvar & A.O. Smith 100233643 Gasket is a critical OEM replacement part engineered for high-output condensing boilers and water heaters. Specifically designed for the Crest FB2500 and FBN2500 models (prior to serial number D14), this burner assembly gasket ensures a high-integrity seal between the burner and the heat exchanger. For technicians performing boiler maintenance or a complete burner assembly overhaul, replacing this component is essential to prevent flue gas leakage and maintain proper combustion pressure. This high-density replacement gasket is built to withstand the intense thermal cycling typical of commercial HVAC systems. As a direct successor to the Lochinvar GKT20028, the 100233643 provides exact dimensional fitment and material compatibility for Lochinvar Crest series units. Ensuring a precise seal at the sight glass and burner interface is vital for system safety and peak equipment efficiency. Rely on genuine Lochinvar parts to maintain factory specifications and structural integrity during every service call.
Key Benefits- Compatible with Lochinvar Crest FB2500 and FBN2500 models manufactured prior to serial D14.
- Engineered to provide a high-temperature seal for the burner assembly and heat exchanger.
- Direct OEM replacement for obsolete part number GKT20028, ensuring exact fitment without field modifications.
- Prevents hazardous combustion byproduct leakage into the mechanical room by maintaining airtight seals.
When should the burner gasket be replaced?
It is standard practice for HVAC contractors to replace the burner gasket during any heat exchanger inspection or when the burner is removed for cleaning to prevent compression set failures.
Does this part fit the newer Crest models?
This specific 100233643 gasket is designed for units produced before serial number D14. Always verify the serial number of your Lochinvar boiler before purchase to ensure part compatibility.
What components are included in this assembly?
This burner assembly kit typically includes the primary sealing gasket and is often utilized alongside sight glass gaskets to ensure a complete seal of the combustion chamber housing.
