Lochinvar & A.O. Smith 100172009 Gas Valve Assembly
The Lochinvar & A.O. Smith 100172009 Gas Valve Assembly is a critical replacement component for high-efficiency condensing boilers, specifically engineered for the Lochinvar Knight XL and various KBN500, KB501, and AW501 models. As a veteran technician knows, the precision of the negative pressure gas valve is vital for maintaining the correct air-to-fuel ratio across the full modulation range of the burner. This natural gas valve assembly (also identified as VAL3207) integrates seamlessly with the SMART SYSTEM control module to regulate heat input based on real-time blower speed and sensor data. It is designed to handle inlet gas pressures between 4" and 14" w.c., ensuring stable combustion even during local supply fluctuations. Whether you are addressing a "Flame Failure" lockout or performing a scheduled teardown on commercial boiler parts, utilizing this OEM heating system component ensures the heat exchanger operates within specified thermal parameters, preventing soot buildup and protecting the structural integrity of the stainless steel combustion chamber.
Key Benefits for the Contractor:- Precise Modulation: Engineered to match the blower’s air intake for consistent boiler firing rate control.
- Direct OEM Compatibility: Replaces part number VAL3207 in Knight XL KBN500 and Floor Standing KB 500/501 series.
- Robust Construction: Built to withstand commercial duty cycles in hydronic heating systems.
- Safety Integration: Features internal solenoids that respond instantly to ignition module safety signals.
- Optimized Performance: Facilitates fully condensing operation to maximize ENERGY STAR efficiency ratings.
What are the symptoms of a failing 100172009 gas valve?
Technicians typically observe "Ignition Failure" or "Flame Fail" codes on the SMART SYSTEM display. If the manometer shows negative pressure at the valve but it fails to open when 24VAC is applied, the solenoid is likely seized, necessitating a 100172009 replacement.
Can this natural gas valve be converted for LP applications?
While this specific assembly is configured for natural gas, conversion depends on the specific boiler model's orifice requirements. Always verify the gas valve adjustment procedure in the technical service manual for LP requirements between 8" and 14" w.c.
Is the gasket included with the assembly?
This kit is the primary valve assembly. It is best practice to inspect the venturi gasket and mounting seals during installation to ensure no gas leaks occur at the interface between the valve and the blower assembly.
