Reznor 257010 Ignition Control Freon Engineered as an SPST normallyThe Reznor 257010 Ignition Control is a critical DSI control board designed specifically for intermittent spark pilot systems requiring a 100% lockout safety sequence. Primarily utilized in Reznor F, FE, B, and BE series unit heaters, this UTEC 1003 514 module is the required replacement for units equipped with a vent damper. A key technical constraint to note: once this controller is interfaced with a vent damper via the wiring harness, the internal
