Lochinvar & A.O. Smith 100171898 Gas Valve

The Lochinvar & A.O. Smith 100171898 Gas Valve is a critical LP gas valve assembly engineered specifically for precise fuel regulation in high-efficiency heating systems. As a direct replacement for the Lochinvar VAL2932, this 2932 LP gas valve ensures the correct stoichiometric ratio for liquid propane combustion, maintaining peak thermal efficiency and reducing NOx emissions. This OEM Lochinvar part features a redundant valve seat design, providing an essential safety layer by ensuring positive shut-off when the main control board removes the 24VAC signal. Designed to interface seamlessly with the electronic integrated control module, the 100171898 manages manifold pressure with high accuracy, preventing flame failure or ignition cycles that can lead to system downtime. Whether you are servicing a Copper-Fin II boiler or a commercial water heater, this replacement gas valve provides the reliability required for 24/7 hydronic operations. Its 3/4-inch NPT inlet/outlet compatibility allows for a standard fit in existing burner manifolds, facilitating a straightforward swap for faulty or sticking valves.

• Direct Replacement: Replaces VAL2932 and is a verified A.O. Smith 100171898 component, ensuring 100% compatibility with specified Lochinvar boiler parts.
• Enhanced Safety: Features redundant valve seats and a built-in low gas pressure regulator for stable fuel delivery and secure shutdown.
• Technical Precision: Tuned for LP gas (Liquid Propane) applications to maintain a consistent burner flame and optimal flue gas temperatures.
• Contractor Grade: Rugged construction prevents internal diaphragm fatigue, a common cause of Lochinvar gas valve failure in high-demand environments.

Common Questions

How do I verify if the 100171898 is the right valve for my unit?
Always check the rating plate on your boiler. This replacement gas valve is identical to the VAL2932. It is commonly utilized in the Lochinvar Copper-Fin II series and specific A.O. Smith commercial water heaters. If your existing valve has the 100171898 or VAL2932 part number, this is the correct OEM replacement.

What are the symptoms of a failing boiler gas valve?
Field technicians typically look for ignition failure codes, often caused by the valve failing to open despite receiving 24VAC power. Other indicators include "lazy" flames due to poor pressure regulation or a total lockout during the trial-for-ignition phase. Replacing a sticking 100171898 gas valve restores consistent burner performance.

Can I use this valve for Natural Gas applications?
No, the 100171898 is calibrated specifically for LP gas. Using an LP valve on a natural gas system will cause improper combustion and potential safety hazards. For natural gas units, ensure you select the specific NAT equivalent part number listed in your service manual.
