Heatco HM56SERIES308 24V Direct Spark Ignition Control

Description

The Heatco HM56SERIES308 is a 24V Direct Spark Ignition (DSI) control module engineered to deliver dependable, precise burner ignition in commercial and residential heating applications. Designed as a genuine Heatco replacement part, this control ensures your heating system starts safely and efficiently every time.

How It Works

Direct Spark Ignition controls eliminate the need for a standing pilot by generating a high-voltage spark directly at the main burner. On a call for heat, the HM56SERIES308 energizes the igniter and gas valve simultaneously, confirms flame presence via the flame-sensing circuit, and locks out safely if ignition is not established — protecting equipment and occupants alike.
