Description
The Fenwal 35-615521-203 Direct Spark Ignition Control 24V is a flame management module used to coordinate safe burner start-up and shutdown in gas-fired equipment. It operates through a programmed control sequence that activates pre-purge airflow, generates high-voltage spark, and monitors flame presence using a sensor input to ensure stable combustion. In HVAC systems used in furnaces, boilers, and commercial heating units, it is positioned within the burner control circuit to manage ignition timing and safety logic. It is connected to gas valves, inducer motors, and flame detection components through low-voltage wiring for synchronized operation.
