Allanson Transformers — Frequently Asked Questions

Common questions about Allanson ignition transformers. Contact our team or call (901) 458-2000 for cross-reference and specification help.

What is the difference between Allanson ferromagnetic ignition transformers and electronic ignitors?

Ferromagnetic transformers (2721 series, 421 series) use a conventional iron-core design to step 120V up to 10,000V secondary for oil burner ignition. Electronic ignitors (2275 series) use electronic circuitry to generate a higher-frequency output — 17,500V secondary at 45mA — producing a more intense spark. The 2275-658 is for the Beckett AFII burner specifically; other 2275 variants cover Wayne and Carlin applications. The ferromagnetic 2721 series covers Beckett A, AF, and AFG. These are not interchangeable — always verify your specific burner model before ordering.

What Allanson transformer replaces the 2721-628A?

The Allanson 2721-628G is the direct replacement for the obsolete 2721-628A. The "G" suffix indicates a replacement gasket is included. Specs: 120V primary, 10,000V secondary, 23mA, mid-point ground. For Beckett A, AF, and AFG oil burners. Not compatible with Beckett NX burners.

What is the difference between the Allanson 2721-628G and 2275-658?

Both are Allanson ignition transformers for Beckett oil burners but they are different product types and for different burner models. The 2721-628G is a conventional ferromagnetic transformer for Beckett A, AF, and AFG burners — 120V / 10,000V, 23mA, mid-point ground. The 2275-658 is an electronic ignitor specifically for the Beckett AFII burner — 120V / 17,500V, 45mA, mid-point ground. These are not interchangeable — the correct model depends on which specific Beckett burner model you have. Check your burner nameplate for the exact model designation.

What are the cross-reference numbers for the Allanson 2721-628G?

The Allanson 2721-628G cross-references to: France 5LAY-04, Webster T-92, Dongan XD-BK103, Sid Harvey T-92. It also replaces the obsolete Allanson 2721-628A and 2721-627. All are ferromagnetic ignition transformers for Beckett A, AF, and AFG oil burners.

What is the Allanson 421-BT636 and what does it replace?

The 421-BT636 is a universal 6-position replacement ignition transformer — 120V / 10,000V, 23mA, mid-point ground — used when the original burner-specific transformer is unavailable. Cross-references: France LAUV, Webster 312-25AX0600, Dongan LJH-90, Sid Harvey T1-15. Includes complete mounting hardware with six-position adaptability. The 444-BT636 is the 240V primary equivalent.

What is the difference between the Allanson 1092 gas burner series variants?

All 1092 series are 120V primary / 6,000V secondary gas burner ignition transformers. The variants differ by which commercial gas burner they fit: 1092-NA = North American, 1092-N = Ray Burner, 1092-H = Cleaver Brooks, 1092-PF-G = Power Flame (with ground wire), 1092-SG = Webster (3-wire primary), 1092-S = Gordon-Piatt, 1092-F = universal replacement with BX connector. All stocked at Memphis Control Center.
