Siemens Building Technology GIB136.1P Actuator 321042-401 Smith 100073343 flame sensor is

Smith 100073343 flame sensor is a critical safety component designed for precise flame rectification in high-efficiency water heaters and boilers

it provides two SPDT line voltage relay outputs

System Protection: Critical for detecting low water temperature alarms to prevent evaporator tube icing and catastrophic failure

whereas the 2-M (110100) requires a physical manual reset after a low-water trip to ensure system safety and code compliance

Siemens Building Technology GIB136.1P Actuator 321042-401 Smith 100073343 flame sensor isThe Siemens GIB136. 1P OpenAir Actuator is a high torque, non spring return (NSR) damper actuator engineered for precise floating control in demanding HVACR systems. Delivering 310 lb in torque, this unit is designed to drive large dampers up to approximately 77 sq. ft. in commercial air handling units. Operating on a 24V AC DC power supply, it features a robust all metal housing and dual auxiliary switches that are independently adjustable for motor
