Lochinvar & A.O. Smith 100112435 Pilot Assembly

The Lochinvar & A.O. Smith 100112435 Pilot Assembly is a critical OEM ignition component engineered for high-performance residential and commercial gas water heaters. As a veteran-grade replacement pilot burner, this assembly ensures reliable ignition sequences and stable flame sensing, preventing nuisance lockouts and equipment downtime. This comprehensive kit typically includes the pilot tube, thermocouple or flame sensor, and precision-calibrated pilot orifice designed for specific BTU inputs. By maintaining a consistent standing pilot or intermittent ignition flame, it facilitates safe main burner light-off across a wide range of Lochinvar and A.O. Smith hydronic systems. When you are troubleshooting ignition failure or weak flame signals, installing this genuine OEM part ensures the system meets original factory specifications for gas pressure and millivolt output. Field-tested for durability, the 100112435 is the professional choice for restoring the ignition system integrity of high-efficiency thermal expansion tanks and boilers.

• OEM Compatibility: Exact-fit Lochinvar pilot assembly and A.O. Smith 100112435 replacement to ensure seamless integration with control valves.
• Enhanced Flame Stability: Engineered to provide a robust pilot flame, minimizing water heater ignition issues and sensor errors.
• Optimized Safety: High-grade thermocouple construction provides fast response times to shut off gas flow if the pilot flame is extinguished.
• Durable Construction: Built with corrosion-resistant materials to withstand high-temperature combustion environments in commercial applications.

What are the signs that my current pilot assembly needs replacement?
If you notice a lazy yellow flame, frequent pilot outages, or if the main burner fails to ignite despite a visible pilot, the orifice may be fouled or the thermocouple failing to generate sufficient millivolts.

Is this assembly compatible with both Natural Gas and Propane units?
Compatibility depends on the specific pilot orifice size. Always verify your equipment’s fuel type and cross-reference the 100112435 part number in the manufacturer’s service manual before installation.

Can I replace just the thermocouple instead of the whole assembly?
While individual components sometimes fail, replacing the complete pilot assembly is the industry-standard best practice to ensure all interconnected ignition parts have matching wear cycles and optimal alignment.
