Lochinvar & A.O. Smith 100172008 Valve
The Lochinvar & A.O. Smith 100172008 Valve is a critical gas valve assembly engineered for high-efficiency hydronic systems, specifically designed for Knight KB and AW series boilers and water heaters manufactured prior to serial I07. This natural gas valve operates on a negative pressure principle, essential for maintaining the precise fuel-to-air ratio required by modern modulating condensing boilers. By regulating flow to the burner based on signal inputs from the main control board, it ensures clean combustion and prevents ignition failure or flame lockout conditions. As an OEM replacement part, it meets the exact factory specifications for BTU input and manifold pressure, providing a direct fit that simplifies field installation for technicians. Using this Lochinvar gas control allows for reliable negative pressure regulation, which is vital for the blower-driven combustion systems found in Knight XL and related models, ensuring the boiler returns to peak performance without the risk of modulation issues.
Key Benefits- Ensures precise combustion control for high-efficiency condensing boilers, reducing fuel waste and emissions.
- Designed for direct compatibility with pre-I07 serial Lochinvar Knight models, eliminating the need for complex field modifications.
- Robust internal solenoid construction provides reliable opening/closing cycles under varying inlet pressures.
- Facilitates accurate gas valve adjustment to meet specific water heater or boiler manifold requirements.
- Helps resolve chronic GV Relay Fail errors when the existing valve coil or internal diaphragm has reached its service life.
Is this valve compatible with Liquid Propane (LP) systems?
No, the 100172008 is specifically a Natural Gas (NAT) assembly. Field conversion to LP requires a manufacturer-approved conversion kit and specific orifice adjustments to maintain safety and performance standards.
What are the symptoms of a failing Lochinvar gas control valve?
Technicians often see ignition lockout (No Flame) or GV Relay Fail codes. If the main control board sends 24VAC to the valve but the manometer shows no rise in negative pressure, the internal mechanism is likely seized.
Can I use this for serial numbers after I07?
This specific gas valve assembly is intended for units prior to serial I07. Always verify your equipment’s serial number and SKU 100172008 compatibility to avoid flame sensing or modulation issues.
