Lochinvar & A.O. Smith 100171945 Gas Valve Kit
If you are servicing a Lochinvar Knight WH85 or A.O. Smith commercial boiler system, the 100171945 Gas Valve Kit (Alternative Part Number VAL30032) is the direct OEM replacement for maintaining precise manifold gas pressure. This assembly is critical for high-efficiency wall-mount boilers, ensuring the correct air-to-gas ratio for stable combustion and reliable high-altitude performance. As a technician, you know that flange-mounted gas valves on these units must maintain a perfect seal at the venturi interface to prevent 100-series fault codes and ignition failure. This kit includes the valve and necessary gaskets to restore factory-spec modulating gas flow. The unit supports both Natural Gas and LP configurations (check orifice for conversion) and is engineered to withstand the high-cycle demands of hydronic heating applications. Identifying a failing solenoid gas valve early prevents intermittent flame loss and ensures your client’s heating loop stays pressurized and efficient through the peak season.
Key Benefits- Direct OEM Compatibility: Specifically engineered for the WH85 / WHN085 series to ensure a drop-in fit without manifold modification.
- Optimal Combustion: Restores precise gas flow control, essential for maintaining the high-efficiency condensing performance of technical boiler systems.
- Durable Solenoid Construction: Built to handle the rapid modulation required by modern HVACR control boards.
- Full Assembly: Comes as a complete gas valve kit, reducing field time by including the essential seals for the venturi connection.
Is this valve compatible with LP conversion?
Yes, this 100171945 gas valve is used in both Natural Gas and Propane applications, though you must verify the specific gas orifice and manifold pressure settings during commissioning.
Will this fix an "Ignition Failure" error?
If your manometer readings show insufficient gas pressure at the outlet during the ignition trial, replacing the solenoid gas valve is the standard protocol for resolving delivery issues.
Does this fit the WHN110 or larger models?
No, this assembly is specifically calibrated for the WH85 / 085 BTU range. Using an incorrectly sized valve will lead to poor combustion CO2 levels and potential heat exchanger damage.
