Lochinvar & A.O. Smith 100171899 Gas Valve
The Lochinvar & A.O. Smith 100171899 Gas Valve is a critical combustion component designed for high-efficiency Liquid Propane (LP) systems. This 2-stage slow open valve is engineered to provide precise fuel regulation, ensuring a soft ignition sequence and a controlled transition to high-fire operation. As a 24V intermittent pilot gas valve, it is frequently utilized in Lochinvar Copper-Fin II boilers and various A.O. Smith commercial water heaters where reliable manifold pressure management is essential for maintaining AHRI thermal efficiency ratings.
For technicians performing field service, note that the 100277952 is the direct replacement for the discontinued 100171899. This successor maintains the same 3/4" NPT inlet and outlet configuration and technical footprint, making it a drop-in solution for Lochinvar 100171899 applications. The slow-opening characteristic is vital for preventing combustion rumble and ensuring stable flame rectification during the initial stages of the heating cycle. Always verify LP gas pressure settings at the manifold tap using a calibrated manometer during installation to match the specific BTU/hr requirements of the appliance.
Key Benefits:- OEM Compatibility: Genuine replacement for Lochinvar and A.O. Smith commercial boilers and water heaters.
- Enhanced Ignition: The slow open mechanism reduces mechanical stress and prevents hard starts in LP gas applications.
- Dual-Stage Precision: Supports 2-stage firing sequences for improved load matching and fuel economy.
- Standardized Ports: Features 3/4 inch inlet/outlet sizes for easy integration with existing manifold piping.
- Safe Operation: 24VAC dual automatic valve design meets rigorous safety codes for redundant shutoff.
Is the 100277952 a direct replacement for the 100171899?
Yes, the 100277952 is the manufacturer-designated direct replacement and is fully compatible with systems requiring the 100171899 part number.
Can this valve be used for Natural Gas systems?
No, this specific model is factory-configured for Liquid Propane (LP). Utilizing it with Natural Gas without an approved conversion kit can result in improper combustion and equipment damage.
Checking gas pressure at the valve:
Technicians should use the 1/8" NPT pressure tap located on the valve body to verify both inlet supply pressure and 2-stage manifold pressure during the firing sequence.
