4. Setup and Installation
The Beckett 51771u Ignitor is designed for straightforward replacement in compatible Beckett "A" base systems. Follow these general steps for installation:
- Power Disconnection: Before beginning any work, ensure the main power supply to the furnace or burner is completely disconnected at the circuit breaker or fuse box. Verify with a voltage tester.
- Access Old Ignitor: Locate the existing ignitor on your burner. It is typically mounted near the nozzle assembly.
- Disconnect Wiring: Carefully disconnect the electrical wires from the old ignitor. Note the polarity if applicable (e.g., white wire to neutral).
- Remove Old Ignitor: Unscrew or unclip the old ignitor from its mounting base.
- Install New Ignitor: Position the new Beckett 51771u Ignitor onto the "A" base. Secure it using the provided screws and clips. Ensure it is firmly seated.
- Connect Wiring: Connect the electrical wires to the new ignitor. For the Beckett 51771u, ensure the white wire is connected to the neutral (common) terminal. The other wire (blue/white stripe or black, depending on the specific model) connects to the hot lead. Use appropriate connectors if necessary.
- Verify Connections: Double-check all electrical and mechanical connections for tightness and correctness.
- Restore Power: Once installation is complete and verified, restore power to the appliance.
- Test Operation: Initiate a test firing of the burner to ensure the new ignitor functions correctly and provides a strong, consistent spark for ignition.
Note: If you are unsure about any step, consult a qualified HVAC technician.
5. Operation
The Beckett 51771u Ignitor is an electronic solid-state device designed to replace older iron core ignition transformers. Its primary function is to generate a high-voltage spark to ignite the fuel (oil or gas) in the burner. When the burner control calls for heat, the ignitor receives power and produces a continuous spark across its electrodes, initiating combustion. This unit provides a strong, consistent spark for reliable burner startup.
6. Maintenance
Regular maintenance of your heating system is crucial for optimal performance and longevity of components, including the ignitor. While the ignitor itself requires minimal direct maintenance, consider the following:
- Annual Inspection: Have your heating system professionally inspected annually. The technician will check the ignitor's performance, electrode condition, and wiring.
- Cleanliness: Ensure the area around the ignitor is free from dust, debris, or oil residue, which can interfere with its operation.
- Electrode Gap: The ignitor's electrodes should maintain the correct gap as specified by the burner manufacturer. This is typically checked during professional servicing.
- Wiring Integrity: Periodically check the ignitor's wiring for any signs of wear, fraying, or loose connections.
7. Troubleshooting
If your burner is not igniting, the ignitor may be a contributing factor. Here are some common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Burner fails to ignite | No spark or weak spark from ignitor. |
|
| Burner ignites, but cycles off quickly | Intermittent spark or flame sensor issue. |
|
| Sooty or smelly startup | Delayed ignition or improper air/fuel mixture. |
|
For complex issues, it is highly recommended to contact a certified HVAC technician.
