Replacement for TP222 Flame Sensor Key benefits Restores reliable flame detection for systems that use the TP222 sensor, helping maintain safe burner operation. Designed to match the original TP222 size, mounting, and electrical connections for a straightforward swap. Provides consistent flame signal performance to minimize nuisance shutdowns and reduce troubleshooting time. Built to meet the TP222 specifications for materials and electrical behavior to ensure compatibility and predictable operation. What it does This replacement flame sensor detects presence of a pilot or main burner flame and provides the corresponding electrical signal to the control module. It is intended as a direct replacement for TP222 style sensors and is engineered to align with the original sensor geometry and connector arrangement. Compatibility and fit Compatible with systems that specify a TP222 flame sensor. Matches the physical footprint, mounting points, and connector pinout of TP222 to allow direct installation without modification. Manufactured to conform to the original TP222 electrical performance requirements. Practical attributes Function: flame presence detection and signal transmission to control electronics. Compatibility: direct replacement for TP222 sensor installations. Size and fit: matches TP222 dimensions and mounting configuration for plug and play replacement. Materials and finish: constructed to meet the same material and build expectations as the original TP222 design. Performance: delivers stable flame sensing behavior consistent with TP222 specifications. Use scenarios Replacing a failed TP222 flame sensor during routine maintenance on a residential gas furnace. Swapping a worn sensor in a commercial boiler to restore reliable flame detection and reduce system interruptions. During scheduled servicing of industrial burners to ensure control systems receive consistent flame presence signals. Installation notes Install using the same mounting and wiring points as the original TP222 sensor. Verify electrical connections match the original TP222 pinout before powering the system.
