Lochinvar & A.O. Smith 100172006 Gas Valve

The Lochinvar and A.O. Smith 100172006 Gas Valve is a critical 24V redundant combination control designed for high-recovery commercial water heaters and boilers. This 3/4" NPT gas valve provides precise fuel regulation for gas-fired equipment, ensuring stable manifold pressure and safe ignition sequences. Known in the industry as a direct replacement for VAL3204, this component is frequently found in Lochinvar Knight and A.O. Smith Cyclone series units. As a veteran technician knows, maintaining the correct gas valve manifold pressure is non-negotiable for combustion efficiency and heat exchanger longevity. This valve manages the flow of natural gas or propane (with appropriate conversion) to the burner assembly, utilizing a dual-seat design for safety redundancy. Whether performing a routine commercial water heater repair or troubleshooting a 100172006 solenoid failure, utilizing this OEM-spec component ensures the system remains within its original AHRI listed performance parameters and safety certifications.

Key Benefits

• Direct OEM Interchangeability: Fully compatible with VAL3204 and factory-specified for Lochinvar and A.O. Smith gas systems.
• High-Flow Capacity: Standard 3/4" inlet and outlet ports accommodate high-BTU load requirements for commercial applications.

Common Questions

Is the 100172006 gas valve compatible with LP gas?
The 100172006 gas valve is typically shipped for natural gas applications but can be converted to propane using the manufacturer-specified LP conversion kit to ensure correct spring tension and orifice delivery.

What are the symptoms of a failing 100172006 gas valve?
Common indicators include failure to ignite despite a verified spark or hot surface igniter glow, "no flame detected" fault codes on the boiler control interface, or inconsistent manifold pressure readings during combustion analysis.

Can I use VAL3204 to replace this unit?
Yes, the 100172006 is identical to VAL3204. They are the same technical component and are used interchangeably across Lochinvar, A.O. Smith, and State Industries commercial product lines.
