Installation Steps

- Locate the igniter blue "hot" and white "neutral" input leads.
- Install the 32302 igniter gasket, if required, and route the leads through the appropriate base plate lead exit hole. Ensure leads are not being crushed.
- Mount the igniter flush to the base plate with the supplied mounting screws.
- Use #6 x 7/16" screws for bottom mounting holes. Use #10 thread-forming paint-scraping screws for the two top mounting holes (for 51771U and 51824U models).
- Tighten all screws securely.
- Install the barrier and base plate gaskets for AF, AFG models. Use gaskets for other burner models as required by the manufacturer.
- Mount the assembled unit to the burner using the supplied screws.
- Use "paint scraping" screws for all burners (2 at the hinge and 2 for non-hinged base plates) to provide effective grounding.
- Verify the burner is properly grounded.
- Route the igniter input leads carefully to prevent pinching during closing. Install the cad cell if applicable.
- Fasten cad cell leads to the control. Wire white to neutral and blue to the primary control ignition lead. Refer to the control or appliance manufacturer’s wiring diagram.
- Verify the igniter secondary output terminals are correctly arranged to make good electrical contact with the oil burner electrodes.
- Close the igniter and install/tighten the front base plate retaining screws (2 or 4 screws depending on hinge).
- Reconnect electric power to the burner circuit.
- Verify with instruments that the burner is adjusted to the manufacturer’s recommended settings.
- Cycle the burner several times to verify prompt and smooth ignition.
Compatibility
The igniter is compatible with various base plates, including models 51771U, 51824U, 51825U, 51827U, 51826U, and 51840U. It fits Beckett residential and commercial burners as well as many other vendors' base plates. For non-Beckett base plates, verify that the igniter fit is free of air leakage.
Practical help
Common problems
Do not use this igniter beyond its design specifications.
Verify the igniter fit is free of air leakage when using non-Beckett base plates.
Cycle the burner several times to verify prompt and smooth ignition before leaving.
Before use
