Lochinvar & A.O. Smith 100171947 Valve

The Lochinvar & A.O. Smith 100171947 Valve, often identified by its legacy SKU VAL30034, is a critical gas valve assembly kit engineered specifically for high-efficiency hydronic systems. This natural gas valve is a direct OEM replacement for the Knight WH155 wall mount boiler, ensuring the precise fuel-to-air ratio required for optimal combustion control. As a veteran-grade gas valve kit, it includes the venturi and necessary gaskets to maintain a hermetic seal within the gas train, preventing dangerous leaks and ensuring system efficiency. When performing a swap-out on a WH155 unit, utilizing this genuine Lochinvar replacement part is the only way to maintain the manufacturer's specified modulation rates and safety parameters. The assembly is designed to handle the rigorous duty cycles of condensing boilers, providing reliable gas flow regulation to the burner assembly. This ensures consistent ignition and heat transfer while minimizing harmful emissions during the firing sequence.

Key Benefits
  • Direct OEM Compatibility: Specifically calibrated for the Knight WH155 boiler to ensure seamless integration and eliminate the need for field modifications.
  • Precision Modulation: Maintains accurate manifold gas pressure to ensure stable flame signals and peak energy conservation.
  • Full Assembly Kit: Includes the gas valve with venturi and high-temp gaskets, providing all necessary components for a professional-grade repair.
  • Durable Construction: Built to withstand the fluctuating pressures and thermal demands of high-recovery hydronic heating applications.
Common Questions

Is this valve compatible with LP (Propane) systems?
This specific kit (100171947) is configured for natural gas applications. If you are converting a WH155 to propane, a dedicated LP conversion orifice or a different valve assembly may be required per the manufacturer's gas train specifications.

What is the primary indicator that this valve needs replacement?
Common field symptoms include repeated ignition failure codes, erratic manifold pressure readings, or physical damage to the venturi housing that compromises the air-fuel mixture.

Does this kit include the wiring harness?
This kit focuses on the mechanical gas valve assembly and venturi. While it integrates with existing 24V leads, a separate lead-wire harness may be needed if the original electrical connections are corroded or damaged.
