| • Verify the receiver is receiving the signal from the transmitter by listening for a |
| beep from the receiver when ON is pressed on the transmitter. If you do not hear |
| a beep, ensure the module has learned the transmitter (see above). |
| • Ensure the orange lead from the pilot assembly igniter is securely connected to |
| the terminal labeled “I” and the white lead from the flame rectification sensor is |
| securely connected to the terminal labeled “S” on the control module. (Fig. 58) |
| • Make sure the orange and white leads from the module are securely connected to |
| the terminals labeled “PILOT” on the valve body. (Fig. 61) |
| • Ensure the black GROUND wire is securely connected to an appropriate metal |
| portion of the valve or pilot assembly. A proper ground is essential to spark |
| igniter operation. |
| • Make certain the pilot flame is in contact with the flame rectification sensor on the |
| pilot assembly. This valve is equipped with a pilot flame adjustment screw. (Fig. |
| 61) If the pilot flame is too small it will not contact the flame rectification sensor |
| and will not complete the safety circuit. |

| • Make certain the pilot flame is in contact with the flame rectification sensor on the |
| pilot assembly. This valve is equipped with a pilot flame adjustment screw. (Fig. |
| 61) If the pilot flame is too small it will not contact the flame rectification sensor |
| and will not complete the safety circuit. |
| • Ensure the pilot flame is properly located to ignite the main flame. |
