4. Connect the Ignition Electrode:
- Identify the ignition electrode connection, often labeled as "I."
- Attach the wire from the ignition electrode to this terminal.
5. Connect the Flame Sensor:
- Locate the flame sensor terminal labeled as "F."
- Connect the flame sensor wire accordingly.
6. Connect the Gas Valve:
- Identify the gas valve connection terminals (usually labeled "G").
- Connect your gas valve control wires to these terminals.
7. Control Signal Connections:
- Follow the wiring diagram to connect any thermostat or control signals.
8. Secure All Connections: Use wire connectors and electrical tape to ensure all connections are secure and insulated.
9. Double-check Wiring: Review your connections against the wiring diagram to confirm accuracy.
10. Restore Power: Once everything is connected, restore power to the heating system.
Troubleshooting Common Wiring Issues
Even with a well-structured wiring diagram, issues can arise. Here are some common problems and their solutions:
1. Ignition Failure
- Possible Causes:
- Faulty ignition electrode.
- Incorrect wiring to the ignition module.
- Solution: Check the electrode for damage and ensure all connections are correct.
2. Flame Sensor Issues
- Possible Causes:
- Dirty flame sensor.
- Loose connections.
- Solution: Clean the flame sensor and check all connections to the sensor.
3. Gas Valve Not Activating
- Possible Causes:
- Incorrect power supply.
- Faulty gas valve.
- Solution: Use a multimeter to check voltage at the gas valve terminals and replace if necessary.
