Lochinvar & A.O. Smith 100233694 Gasket
The Lochinvar & A.O. Smith 100233694 Gasket is a critical OEM replacement part designed to maintain the integrity of the gas train kit and venturi assembly in high-efficiency condensing boilers and water heaters. Engineered for a precision fit, this venturi gasket serves as a robust thermal and atmospheric barrier, preventing air-fuel mixture leaks that can compromise combustion stability and unit efficiency. This specific component is frequently required for service on Lochinvar Knight XL (KBN) and Armor (AW) series units, particularly the KBN600-800 and AW601-850 models. As a veteran-grade heating boiler part, it ensures that the interface between the venturi and the blower maintains a gas-tight seal, protecting the system from improper CO2 levels and potential lockout codes. Utilizing genuine 100233694 gas train gaskets during preventative maintenance or gas valve service is essential for meeting factory pressure specifications and ensuring long-term operational reliability in commercial and residential hydronic applications.
- Precision OEM Fit: Specifically engineered for Lochinvar Knight XL and Armor series, ensuring a perfect seal without the need for modifications.
- Enhanced Combustion Stability: Prevents bypass leaks in the venturi assembly, maintaining the correct air-to-gas ratio for peak burner performance.
- High-Temperature Durability: Constructed from professional-grade materials designed to withstand the thermal cycling inherent in high-output condensing chambers.
- Critical Safety Barrier: Eliminates the risk of fuel gas or exhaust leakage within the gas train, ensuring compliance with strict mechanical codes.
Common Questions:
Which models are compatible with the 100233694 gasket?
This gasket is primarily used in Lochinvar KBN600 through KBN800, FTXL, and Armor AW601 through AW801 models. Always verify your specific serial number for the exact gas train configuration.
Is this gasket required when replacing a gas valve or blower?
Yes, technicians should always replace the venturi gasket whenever the gas train is disassembled to ensure a secure seal and prevent post-service leaks.
How do I identify a failing gas train gasket?
Signs include irregular combustion readings, soot buildup near the venturi interface, or distinct "whistling" sounds during the blower's pre-purge and ignition cycles.
