UIB S Post ignition-board selection

The Dinosaur UIB S Post is the small 12 VDC ignition board with a post-style spark connector. It is distinguished from the conventional spark-connector UIB S and the larger UIB L/Post boards. It is intended for eligible DSI ignition-control applications in furnaces, water heaters and certain refrigerators when original electrical configuration and terminal arrangement match.

Verify the original ignition-board number, spark-post style, control voltage, pinout, mounting dimensions and flame-sense connection before ordering. Manufacturer jumper settings for instant-fire water-heater/refrigerator configurations differ from furnace settings. Do not substitute solely because the original appliance uses 12 VDC.
