Lochinvar & A.O. Smith 100110884 Gas Valve

The Lochinvar & A.O. Smith 100110884 Gas Valve is a critical OEM replacement component designed for high-efficiency commercial boilers and water heaters. Engineered to operate on a 24V control circuit, this natural gas valve features a standard 3/4 inch NPT connection and is factory-calibrated to a 4 inch WC (Water Column) manifold pressure. This unit serves as a direct replacement for legacy part number 9006085205, ensuring seamless mechanical and electrical integration without the need for field modifications. Whether you are servicing a Lochinvar Knight or an A.O. Smith Cyclone series, maintaining precise gas pressure regulation is vital for combustion stability and system safety. Built for rigorous duty cycles, the 100110884 gas control provides the reliable solenoid actuation required to prevent nuisance lockouts and optimize thermal output in demanding commercial HVACR environments.

• Broad Compatibility: Direct OEM replacement for Lochinvar and A.O. Smith technical part numbers 100110884 and 9006085205.
• Precision Calibration: Pre-set to 4" WC to ensure optimal fuel-to-air ratios in natural gas applications.
• Robust Construction: Designed for high-cycle commercial use, reducing mechanical failure in the field.
• Standardized Threading: Features a 3/4" NPT inlet and outlet for rapid installation in standard manifolds.

Is this valve compatible with Propane (LP) systems?
No, this specific model is calibrated for natural gas at 4" WC. Using it for LP without a manufacturer-approved conversion kit can lead to hazardous operating conditions.

Does this unit replace part number 9006085205?
Yes, the 100110884 is the current authorized replacement for the older 9006085205 part number commonly found in older A.O. Smith and Lochinvar manuals.

What voltage does the solenoid require?
This is a standard 24V gas valve and must be powered by a dedicated 24VAC transformer or integrated control board.
