Product Overview
The Beckett 5270001U is a 12 Volt DC ignitor designed for use with ADC oil burners. This unit provides a constant duty ignition source, delivering a 20KV peak, 30 mA, 14,000 Volt spark with a midpoint grounded configuration. It is commonly found in 12VDC pressure washers from various brands, including Hot and Hotsy, that utilize Beckett ADC oil burners. This ignitor replaces several Beckett models, including 5218301U, 5218301, 51777U, 51776U, S3-33XB-BADC, and Grainger 35U298. It can also serve as a replacement for a Carlin 40900S used on a Beckett ADC Burner.

Safety Information
Always disconnect power before installing or servicing the igniter. Improper installation or handling of high-voltage components can result in serious injury or death. Consult a qualified technician if you are unsure about any installation steps. Ensure all connections are secure and insulated to prevent electrical hazards.
Setup and Installation
The Beckett 5270001U igniter is designed for straightforward replacement in compatible systems. Follow these general steps for installation:
- Power Disconnection: Before beginning any work, ensure that the power supply to the oil burner or pressure washer is completely disconnected. Verify with a voltmeter.
- Access Old Igniter: Locate and carefully remove the existing igniter from the burner assembly. Note the orientation and wiring connections before removal. Taking photographs can be helpful.
- Wiring: Connect the wires of the new Beckett 5270001U igniter to the corresponding terminals. The input voltage is 12VDC. Ensure correct polarity and secure connections. This igniter does not include an ignitor control board.
- Mounting: Securely mount the new igniter in its designated position within the burner assembly. Ensure it is stable and properly aligned.
- Reassembly: Reassemble any covers or components that were removed to access the igniter.
- Power Reconnection: Once installation is complete and all connections are verified, restore power to the unit.
Note: Older style igniters may have contained a fifth, white wire. The 5270001U does not utilize this wire.
Operating Instructions
The Beckett 5270001U igniter operates automatically as part of the oil burner or pressure washer's ignition sequence. Once properly installed and connected to a 12VDC power source, it will generate a high-voltage spark to ignite the fuel when commanded by the system's control board.
- Ensure the fuel supply is adequate and the burner system is primed according to the manufacturer's instructions for the specific appliance.
- Initiate the start sequence of your oil burner or pressure washer. The igniter should produce a consistent spark to facilitate combustion.
- Monitor the system for proper ignition and stable operation.
Maintenance
The Beckett 5270001U igniter is a sealed unit and generally requires minimal maintenance. However, regular inspection of the surrounding components is recommended:
- Wiring Inspection: Periodically check all electrical connections for tightness and signs of wear or corrosion. Ensure insulation is intact.
- Cleanliness: Keep the area around the igniter clean and free from dust, debris, or oil residue, which can interfere with proper operation or pose a fire hazard.
- Electrode Gap: While the igniter itself is sealed, the electrodes it powers (if external) should be checked for proper gap and cleanliness according to the oil burner's specific maintenance guidelines.
Troubleshooting
If the oil burner or pressure washer fails to ignite, consider the following troubleshooting steps related to the igniter:
| Problem | Possible Cause | Solution |
|---|---|---|
| No Spark | No 12VDC power to igniter. Faulty wiring connection. Defective igniter. | Check power supply to the igniter. Inspect and secure all wiring connections. Test igniter for proper output; replace if defective. |
| Weak or Intermittent Spark | Low input voltage. Loose connections. Internal igniter issue. | Verify 12VDC input voltage is stable. Tighten all electrical connections. Replace igniter if problem persists. |
| Burner Fails to Ignite (Igniter sparks) | Fuel supply issue. Air supply issue. Other burner component failure. | Check fuel lines, filter, and pump. Ensure proper air intake. Consult the oil burner's specific manual or a qualified technician. |
If troubleshooting steps do not resolve the issue, it is recommended to contact a qualified service technician.
