Lochinvar & A.O. Smith 100110867 Gas Valve

Upgrade or repair your heating system with the Lochinvar & A.O. Smith 100110867 Gas Valve, a critical component engineered for precision fuel management in high-efficiency natural gas water heaters and boilers. This authentic OEM replacement part is specifically designed for commercial gas water heaters within the BCG3 series, including 65T300 and 100T390 models. As a veteran-grade HVAC replacement part, it ensures proper manifold pressure and reliable ignition sequences, preventing the common "no flame" or "ignition lockout" faults that plague compromised systems.

The Lochinvar 100110867 features a robust 1/2-inch or 3/4-inch NPT configuration (verify your specific chassis) and manages NG fuel regulation with high-tolerance solenoid coils. By utilizing this heating system gas control, technicians can restore factory-spec combustion efficiency and maintain the negative pressure requirements typical of advanced Lochinvar Knight and A.O. Smith Cyclone units. This valve is the direct successor to obsolete part number 9006066205, offering a seamless fit and electrical compatibility with existing wiring harnesses.

• Direct OEM Compatibility: Verified fit for A.O. Smith BCG3-65T300, 100T390, and equivalent Lochinvar commercial heating units.
• Precision Pressure Regulation: Maintains consistent natural gas flow to the burner assembly for optimal thermal output and reduced emissions.
• Industrial-Grade Build: Constructed to withstand the high-cycle demands of commercial-grade hydronic and domestic hot water applications.
• Enhanced Safety: Quick-response solenoid action ensures immediate fuel shut-off during flame failure or high-limit excursions.

• How do I confirm if my existing valve is failing? If you have 24V at the 2-pin connector during the ignition trial but see no change in manifold pressure on your manometer, the solenoid has likely seized.
• Can this valve be converted to Liquid Propane (LP)? No, this specific part number is calibrated exclusively for natural gas applications; always use the manufacturer-specified LP conversion kit or dedicated LP valve for propane systems.
• Is this a direct replacement for the 9006066205? Yes, the 100110867 is the current authorized replacement for the older 9006066205 gas valve assembly.
