the A70 is precision-ground for dimensional consistency

Mechanical Protection: Brass friction washers minimize friction during assembly

it allows for precise airflow modulation to meet specific cooling and heating load requirements

What is the difference between this and a starter solenoid

Fireye EP380 Module 320074-702 the A70 is precision-ground forThe Fireye EP380 is a specialized microprocessor based programmer module designed for use within the Flame Monitor burner management system. This EP style plug in module provides a fixed 30 second purge cycle and dual trial ten second ignition (TFI) timing, specifically engineered for non modulating burner applications. As a critical component of the Fireye FLAME MONITOR chassis, it handles the sequencing of burner startup, monitoring the flame signal
