Lochinvar & A.O. Smith 100172014 Valve
The Lochinvar & A.O. Smith 100172014 Gas Valve Assembly is a critical OEM replacement component designed for high-efficiency natural gas firing in commercial and industrial heating systems. Specifically engineered for the Knight XL KBN600, KBN601, and Armor AW600 series boilers and water heaters, this assembly replaces the obsolete VAL3212. As a veteran-grade HVACR part, it ensures precise manifold pressure regulation and stable gas-to-air mixtures, which are vital for maintaining the 90%+ AFUE ratings of condensing units. The valve operates on a 24 VAC signal and is built for negative pressure systems common in modulating-condensing equipment. When troubleshooting flame failure or GV Relay Fail codes on the SMART SYSTEM control board, this 100172014 assembly is the direct solution to restore safe, reliable ignition and consistent BTU input. This genuine boiler gas valve maintains the original equipment’s service life and performance specifications without the risks associated with universal or aftermarket alternatives.
Key Benefits- Direct OEM Replacement: Engineering match for VAL3212, ensuring seamless mechanical and electrical fitment for Knight KBN and Armor AW models.
- Modulating Performance: Supports precise gas flow control required for high-efficiency modulation, preventing short-cycling and optimizing fuel consumption.
- Durable Construction: Heavy-duty housing designed to withstand the high-demand cycles of commercial water heating and hydronic boiler applications.
- Safety First: Features integrated internal shut-off mechanisms to ensure reliable gas closure during lockout or power failure scenarios.
Is this valve compatible with LP (Liquid Propane) systems?
No. The 100172014 is specifically calibrated for Natural Gas applications. Converting this valve to LP requires a specific manufacturer-approved orifice kit; do not attempt conversion without the correct OEM conversion components.
How do I troubleshoot a "GV/Relay Fail" error on my Lochinvar boiler?
First, verify 24 VAC at the black Molex connector. Use a manometer to check if the negative gas pressure rises toward zero during the ignition trial. If voltage is present and the valve fails to open, the assembly typically requires replacement.
Can I install this valve myself?
Installation must be performed by a licensed HVAC technician. Proper commissioning requires a combustion analyzer to verify CO2/O2 levels and a digital manometer to ensure the gas supply pressure stays between the 4.0" W.C. and 14.0" W.C. operating range.
