Lochinvar & A.O. Smith 100288534 Gas Valve
The Lochinvar & A.O. Smith 100288534 Gas Valve is a critical OEM replacement part designed for natural gas-fired heating systems, specifically commercial boilers and high-output water heaters. As a standing pilot gas valve, it provides reliable mechanical gas flow control, ensuring a consistent pilot flame and stable burner ignition across rigorous duty cycles. This unit is the direct replacement for 100171890, engineered to meet the precise manifold pressure requirements of Lochinvar and A.O. Smith equipment. Featuring a 1/2-inch NPT inlet/outlet and high-grade internal diaphragms, this valve maintains optimal fuel-to-air ratios to maximize thermal efficiency and prevent nuisance lockouts. For technicians performing HVAC system maintenance, this gas control valve ensures rapid response times and drop-in compatibility with existing pilot burner assemblies, significantly reducing downtime during emergency service calls.
Key Benefits
- Direct OEM Compatibility: Engineered specifically to replace legacy part number 100171890 without the need for manifold modifications.
- Industrial-Grade Control: Utilizes a standing pilot ignition system for simplified troubleshooting and reliable 24/7 operation in commercial environments.
- Enhanced Fuel Efficiency: Precision-calibrated natural gas flow regulation prevents over-firing and reduces overall energy consumption.
- Durable Construction: Built to withstand the high-temperature demands of boiler gas valve applications, ensuring long-term structural integrity.
Common Questions
Is the 100288534 compatible with propane (LP) systems?
No, this specific model is calibrated for natural gas (Nat Gas) only. Converting gas valves can lead to unsafe combustion; always match the fuel type to the rating plate of the equipment.
What does it signify if my current valve 100171890 is discontinued?
The 100288534 is the manufacturer-designated successor. It features the same technical specifications and mounting footprint to ensure seamless field replacement.
How do I verify if this valve is the cause of my pilot light failing?
Check the thermocouple output first; if the thermocouple generates acceptable millivolts but the 100288534 valve fails to hold the pilot, the internal electromagnetic coil may be compromised, requiring a full valve replacement.
