Lochinvar & A.O. Smith 100171948 Gas Valve Kit
The Lochinvar & A.O. Smith 100171948 Gas Valve Kit is a critical OEM component engineered specifically for the Knight WH199 wall-mount boiler and compatible high-efficiency water heaters. This assembly serves as the primary regulator for fuel delivery, ensuring precise negative pressure gas valve operation required for clean combustion and stable flame signals. Designed to interface directly with the Smart System control board, the kit includes the essential gaskets and venturi components necessary to restore the pressure differential at the burner head, preventing common ignition failure and flame failure faults.
For technicians troubleshooting a boiler not igniting, this kit resolves issues where the 24VAC signal is present at the solenoid but the internal diaphragm fails to actuate. The Lochinvar 100171948 is a genuine replacement part built for the high-demand cycling of commercial and residential HVAC systems. Replacing an aging valve with this factory-spec kit ensures the unit maintains its AFUE rating and operates within the manufacturer's specified CO2 and O2 combustion parameters.
- OEM Compatibility: Exact fit for Lochinvar Knight WH199 and corresponding A.O. Smith models.
- Integrated Venturi: Factory-aligned venturi ensures correct air-fuel nesting for modulated firing rates.
- Complete Kit: Includes high-temperature gaskets to prevent fuel leaks and ensure a gas-tight seal.
- Reliable Regulation: Maintains consistent manifold pressure during high and low-fire operational modes.
- Does this kit include the mounting gaskets? Yes, the 100171948 comes with the necessary gaskets and hardware for a professional-grade installation.
- Will this fix an "Ignition Failure" fault? If your multimeter confirms voltage to the gas valve solenoid but no fuel flow is detected via manometer, this kit is the required solution.
- Is this compatible with LP or Natural Gas? This kit is typically configured for Natural Gas; always verify orifice requirements if converting to Liquid Propane.
