Lochinvar & A.O. Smith 100233617 Gasket
For veteran technicians servicing high-capacity Lochinvar Knight boilers or A.O. Smith water heaters, the 100233617 Gasket is a critical component for maintaining combustion integrity. Engineered as a large gas air arm cover gasket, this seal is primarily utilized in the gas/air arm assembly to prevent dangerous fuel-air mixture leaks. This specific part is a direct OEM replacement for legacy part numbers GKT20019, GKT20019K, and 100146349. Measuring approximately 8.313 inches square, it provides a high-tolerance seal for FBL and FBN models, including the 2500, 3000, and 3500 series. When performing a boiler burner teardown or a commercial water heater repair, replacing this gasket ensures the HVAC combustion system operates at peak thermal efficiency. Its high-temperature resistance is purpose-built to withstand the corrosive environment of an industrial gas burner, preventing pressure loss and protecting the gas-fired equipment from premature failure during high-demand cycles.
Key Benefits- Precise OEM Fit: Designed specifically for Lochinvar and A.O. Smith gas air arm configurations, ensuring zero-gap sealing.
- Enhanced Combustion Safety: Eliminates gas leakage at the burner cover, crucial for meeting HVAC safety standards.
- High-Temperature Durability: Constructed from professional-grade materials that resist thermal degradation in commercial boilers.
- Legacy Compatibility: Fits systems originally requiring GKT20019, simplifying inventory for field service.
Which Lochinvar models use the 100233617 gasket?
This gasket is commonly found in Lochinvar Knight and larger gas-fired units, specifically the FBL/FBN 2500-3500 series.
Is this the same as the GKT20019 part?
Yes, 100233617 is the updated manufacturer part number and serves as a direct replacement for the obsolete GKT20019 and GKT20019K.
Why is it necessary to replace this during burner maintenance?
Standard preventative HVAC maintenance requires replacing this gasket whenever the gas air arm is removed to prevent hairline leaks that compromise combustion and safety.
