Lochinvar & A.O. Smith 100233654 Gasket
The Lochinvar & A.O. Smith 100233654 Gasket Set is a critical OEM replacement kit designed for high-capacity heating systems, specifically the FBL3500 and FBN3500 burner assemblies. This comprehensive set includes the primary burner gasket, hex gaskets, and sight glass seals required to maintain a gas-tight seal during routine teardowns or full combustion chamber overhauls. As a seasoned technician knows, reusing compressed gaskets on industrial boilers like the Lochinvar Knight or A.O. Smith Cyclone series risks CO leakage and inefficient fuel-to-air ratios. This kit ensures a precise fit for units manufactured prior to serial number D14, replacing legacy part numbers GKT20030 and GKT20030K. Engineered to withstand high-temperature fluctuations, these seals prevent bypass air from compromising the heat exchanger’s integrity. Relying on genuine OEM HVAC parts is the only way to ensure the unit stays within its original factory performance curve and passes safety inspections without incident. Precise boiler gasket replacement is mandatory for any burner service to prevent costly downtime.
Key Benefits- Direct OEM Compatibility: Specifically engineered for FBL/FBN 3500 series burner assemblies for a perfect mechanical fit.
- Comprehensive Sealing: Includes burner, hex, and sight glass gaskets to address all potential leak paths in the assembly.
- High-Temperature Resistance: Constructed from professional-grade materials designed to maintain structural integrity under extreme thermal cycling.
- Cross-Reference Support: Validated replacement for discontinued part numbers 100146360 and GKT20030.
Does this kit include the sight glass gasket?
Yes, the 100233654 is a full gasket set that includes the sight glass seal, burner gasket, and hex gaskets for a complete service.
Is this compatible with newer serial numbers?
This specific set is designated for Lochinvar and A.O. Smith units produced prior to serial number D14. Check your data plate before installation.
Why is an OEM gasket required over a universal seal?
OEM gaskets are cut to exact tolerances to match the burner flange, ensuring no gas bypass or vacuum loss, which is critical for modulating-condensing equipment.
