Lochinvar & A.O. Smith 100108592 Gas Valve

The Lochinvar & A.O. Smith 100108592 Gas Valve is a critical replacement component for high-efficiency natural gas water heaters and commercial boiler systems. Designed for precision fuel regulation, this 3/4" NPT Gas Valve features a robust two-piece construction and is engineered to maintain optimal manifold pressure for consistent combustion. This specific Natural Gas Control Valve comes equipped with an integrated thermocouple (T-Couple), ensuring the flame safety circuit remains closed during standard operation and providing an immediate shut-off if the pilot flame is extinguished. This HVAC gas valve replacement is a direct match for various Lochinvar and A.O. Smith models, supporting systems that require a 5 PSI maximum operating pressure. As a veteran-grade OEM water heater part, it handles gas flow with minimal pressure drop, typically functioning within a temperature range of -20 to 125 degrees F. The 100108592 control valve utilizes a 24V AC intermittent pilot or standing pilot configuration depending on the specific appliance's ignition board requirements, making it a versatile choice for field technicians servicing heavy-duty commercial heating equipment.

• Precision Pressure Regulation: Maintains stable natural gas delivery to the burner assembly for peak thermal efficiency.
• Integrated Safety: Features a high-response thermocouple to prevent gas accumulation in the event of a flame-out.
• Industry Standard Connections: Utilizes 3/4" NPT female threaded ports for a secure, leak-free installation on standard gas lines.
• OEM Compatibility: Specifically engineered as a drop-in replacement for Lochinvar and A.O. Smith part number 100108592.
• Durable Construction: Built with high-grade brass and components rated for commercial-grade duty cycles.

What are the symptoms of a failing 100108592 gas valve?
Technicians often see "Ignition Failure" or "Flame Loss" codes on the control board. If the thermocouple fails to generate the necessary millivolts or the solenoid coil is open, the valve will not allow gas to reach the main burner.

Is this valve compatible with Liquid Propane (LP) systems?
No, this specific model is calibrated for Natural Gas applications. Converting or using this valve for LP without a manufacturer-approved conversion kit can lead to hazardous operating conditions.

Does this assembly include the thermocouple?
Yes, the 100108592 is a Gas Valve with Thermocouple (T-COUPL) assembly, ensuring you have the primary safety components needed for the installation.
