Lochinvar & A.O. Smith 100171987 Valve
Upgrade your system with the Lochinvar & A.O. Smith 100171987 Gas Valve Assembly, a critical component for maintaining precise manifold pressure in high-efficiency water heaters and boilers. This OEM gas valve replacement is designed to regulate natural gas and propane flow with a redundant valve seat configuration, ensuring reliable ignition and stable combustion cycles. Integrating this genuine part into your HVAC gas valve assembly prevents common lockout issues and fluctuating burner performance often seen with aftermarket equivalents. Specifically engineered for Lochinvar and A.O. Smith equipment, this 100171987 valve assembly features a built-in pressure regulator and is referenced to the combustion chamber for optimal air-gas mixture. As a veteran technician knows, maintaining water heater gas valve integrity is paramount for safety and equipment longevity. This 2.56-lb assembly provides the responsive modulation needed for modern Smart System controls and 24V ignition circuits, delivering the mechanical precision required for high-demand commercial and residential applications.
Key Benefits- Precise Flow Regulation: Ensures consistent natural gas and propane delivery to the burner for steady 120V or 24V operation.
- Enhanced Safety: Features redundant valve seats to prevent gas leakage and ensure positive shut-off during standby.
- OEM Compatibility: Guaranteed fit for specific Lochinvar and A.O. Smith boilers, eliminating the need for field modifications.
- Improved Efficiency: Helps maintain stable manifold pressure, reducing fuel waste and preventing premature carbon buildup on heat exchangers.
What are the signs of a failing 100171987 gas valve?
Common indicators include the burner failing to ignite despite a 24V call for heat, erratic flame signals, or "Low Gas Pressure" faults on the control board. Always verify inlet pressure and coil resistance before replacing the assembly.
Can this gas valve be used for both Natural Gas (NG) and Liquid Propane (LP)?
Yes, this assembly is rated for NAT/LP applications. However, ensure the appropriate conversion kit or internal settings are applied per the manufacturer’s installation manual to match your specific fuel source.
Does this assembly include the ignition control?
No, this is the mechanical valve assembly. While it works in tandem with the ignition control and hot surface igniter, it does not include the electronic control board.
