a. The Direct Spark Ignition (DSI) Module is a 24 VAC device designed to be the "controller" of the DSI system. When activated by the dryer controls, this module constantly monitors and controls the functions of the DSI system (i.e., spark activation, gas valve off and on, flame verification, etc.). Additionally, the DSI Module has self diagnostic capabilities.
