Lochinvar & A.O. Smith 100110861 Valve
The Lochinvar & A.O. Smith 100110861 is a high-performance Liquid Propane (LP) gas valve designed for critical regulation in hydronic boilers and water heating systems. This 24V step-opening gas valve is pre-configured for a 11" WC (Water Column) output, ensuring stable manifold pressure for efficient combustion cycles. Featuring a 1/2" NPT inlet and a 3/4" NPT outlet, it provides a secure fit for standard residential and commercial piping architectures. The unit is engineered for compatibility with various ignition types, including Direct Spark Ignition (DSI) and Hot Surface Ignition (HSI) systems.
As an OEM replacement for part numbers 9006059205 and White Rodgers 36C74-314, this valve is a staple for technicians troubleshooting ignition lockout or flame failure codes on Lochinvar Knight and A.O. Smith residential power vent units. The robust internal solenoid allows for precise gas flow regulation, maintaining a maximum pressure rating of 0.5 PSI. When executing a gas valve replacement, always verify inlet pressure and perform a combustion analysis to confirm the 11" WC LP setting aligns with the equipment’s data plate requirements.
- Universal Compatibility: Serves as a direct OEM drop-in for Lochinvar boilers and A.O. Smith water heaters, reducing field modification time.
- Optimized LP Regulation: Factory-set at 11" WC to ensure the stoichiometric ratio is maintained for propane-burning appliances.
- Durable Construction: Engineered to withstand the high-cycle demands of modern 24V HVAC controls and ignition sequences.
- Standardized Porting: The 1/2 x 3/4 gas valve configuration facilitates simple integration into existing gas trains without excessive adapters.
Common Questions & Troubleshooting
What are the signs that my 100110861 gas valve has failed?
Technicians typically observe a "GV Relay Fail" or ignition lockout. If you have 24VAC at the valve terminals during the trial for ignition but the manifold pressure remains at 0" WC, the internal solenoid has likely failed.
Can this valve be used for Natural Gas (NG) applications?
No. This specific model is strictly for Liquid Propane (LP) systems with an 11" WC rating. Using this on a natural gas system will cause hazardous combustion conditions.
Does this valve require a specific wiring harness?
It utilizes a standard 2-pin or 3-pin Molex-style connector common in A.O. Smith and Lochinvar assemblies. If your harness shows signs of heat damage or corrosion, it should be replaced alongside the valve to prevent resistance issues.
