Lochinvar & A.O. Smith 100109294 Pilot Assembly

The Lochinvar & A.O. Smith 100109294 Pilot Assembly is a precise OEM replacement engineered for Flammable Vapor (FV) ignition systems. Designed for use in Propane (LP) residential water heaters, this 160 Degree Celsius rated assembly ensures critical thermal safety by maintaining the correct ignition sequence and flame rectification. As a high-performance FV Pilot Assembly, it integrates a durable thermopile or thermocouple (depending on specific model revision) and a dedicated igniter lead to provide consistent pilot flame stability in sealed combustion chambers. Professional technicians recognize this part as the standard for resolving persistent pilot outages or "no hot water" calls caused by thermopile voltage drop or soot accumulation on the pilot hood. This genuine A.O. Smith part is specifically calibrated to meet the CVD technology requirements, ensuring that the 160°C thermal cutoff functions within factory parameters to prevent safety hazards. For optimal performance, verify your model and serial number to ensure compatibility with this LP gas pilot assembly before installation.

• OEM Precision: Direct Lochinvar & A.O. Smith 100109294 replacement ensures exact fitment and proper voltage signal to the gas control valve.
• Propane Optimized: Specifically jetted for LP gas applications to maintain flame stability and reduce carbon buildup.
• Enhanced Thermal Safety: Rated at 160°C to accurately monitor combustion chamber temperatures and prevent vapor ignition risks.
• Tech-Ready Design: Features reinforced lead wires and a high-grade pilot hood designed for longevity in high-heat environments.

• Will this fix a pilot that won't stay lit? Yes, if the failure is due to a degraded thermopile or a restricted pilot orifice, this assembly restores the millivolt signal required to hold the gas valve open.
• Is this compatible with Natural Gas units? No, the 100109294 is specifically designed for Propane (LP) systems; using it with Natural Gas will result in improper combustion.
• Does this include the igniter? This assembly typically includes the pilot tube, igniter wire, and thermopile/thermocouple as a complete FV pilot solution.
