UIB S small ignition-board replacement cross-references

Dinosaur UIB S is the small 12-volt DC universal ignitor board, approximately 3.25 by 4.25 inches. Dinosaur's manufacturer cross-reference lists it for specific ignitor controllers such as Fenwal 05-309001-153 and Atwood 93253 AC/Gas; an original board match is required. UIB S is distinct from the spark-post UIB S Post and larger UIB L boards.

Check the original circuit-board marking, its full connector arrangement and spark terminal before ordering. Furnace operation and water-heater/refrigerator instant-fire settings can require different jumper configuration. Manufacturer instructions and trained LP-gas service determine correct installation; 'universal' does not mean all RV ignition boards interchange.
