Laars Heating Systems FT1804 Sensor Els PW 29614 Robust Environmental Protection: The NEMA

Robust Environmental Protection: The NEMA 4X watertight enclosure protects internal components in harsh or corrosive environments

Precise Ignition Control: Optimizes 120V hot surface igniter or spark timing to reduce fuel waste during prepurge cycles

the probe may be fouled by scale or the ceramic insulator may be cracked

Use a multimeter to verify signal output from the primary controller

check the motor nameplate for specific MFD requirements to ensure proper starting torque

Laars Heating Systems FT1804 Sensor Els PW 29614 Robust Environmental Protection: The NEMAThe Laars Heating Systems FT1804 Sensor is a precision engineered OEM air pressure transducer specifically designed for Mascot FT boiler systems. As a critical safety component, this boiler pressure sensor continuously monitors differential air pressure to verify proper airflow before the burner cycle initiates. By providing real time feedback to the integrated control board, the FT1804 prevents dangerous combustion conditions and high limit events.
