Fenwal 35-705501-003 Control 30067439-890 For setups requiring downstream pressureThe Fenwal 35 705501 003 is a dedicated 120VAC Direct Spark Ignition (DSI) control designed for precise gas burner management in commercial and industrial HVACR applications. This microprocessor based ignition module features a 7 second Trial for Ignition (TFI) period and is engineered for single try configurations. As a non prepurge (NoPP) unit, it initiates the spark sequence immediately upon the call for heat, making it an essential component for
