|
| sense lead is at least 0.14 microamps. Verify correct pilot | |
|
| orifice is installed and gas inlet is set to pressure specifi- | |
|
| cations. Polish flame sensing rod with fine steel wool to | |
|
| remove any contaminants that may have accumulated on | |
|
| flame sensing rod. | |
|
|
| |
| C. Module is not grounded. | Verify module is securely grounded to metal chassis of ap- | |
|
| pliance. Verify that wire harness is firmly connected to the | |
|
| module. | |
|
|
| |
| D. Damaged pilot assembly or contami- | Verify that ceramic insulator around the flame sensing rod | |

|
| flame sensing rod to white sensor wire. Polish flame sens- | |

| that may have accumulated on flame sensing rod. Verify | |
|
| continuity with a | |

| Replace pilot if any damage is detected. | |
|
|
| |
5. Carbon Deposition | A. Log Placement | Verify placement and assure flame is not excessively | |
|
| impinging on log. | |
| B. Shutter Setting | Check to assure correct shutter setting for your model and | |
|
| gas type. | |
| C. Gas Type | Assure correct fuel matches unit gas model and components. |
