Verify that ceramic insulator around the sensor rod is not cracked, damaged,
or loose. Verify connection from sensor rod to white sensor wire. Clean
sensor rod with emery cloth to remove any contaminants that may have
accumulated on sensor rod. Verify continuity with a multimeter with ohms set
at lowest range.

wire "I" from module. Place ON/OFF Rocker switch or wall switch in ON
position. Hold ground wire about 3/16 inch away from "I" terminal on module.
If there is no spark at "I" terminal module must be replaced. If there is a spark
at "I" terminal, module is fine. Inspect pilot assembly for shorted sparker wire
or cracked insulator around electrode.
Verify that incoming gas line ball valve is "open". Verify that inlet pressure
reading is within acceptable limits, inlet pressure must not exceed 14 in. W.C.
Verify that spark gap from ignitor to pilot hood is .17 in. or 1/8 in.
