| tion. Remove ignitor 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. | |

| b. Ignitor gap is too large. | Verify that spark gap from ignitor to pilot hood is .17 in. or | |
|
| 1/8 in. | |
|
|
| |
| c. Module is not grounded. | Verify module is securely grounded to metal chassis of | |
