Allanson Transformers 2741-658 Transformer

The Allanson Transformers 2741-658 is a heavy-duty ferromagnetic ignition transformer engineered specifically for the Beckett AFII oil burner. As a veteran-grade oil burner transformer, it provides a stable 10,000Vac secondary voltage with a 23mA output, ensuring a consistent arc for reliable ignition in demanding residential and commercial heating environments. Built with high-temperature wire and a mid-point ground configuration, this unit is designed to run cooler and quieter than standard aftermarket alternatives. The Allanson 2741-658 meets rigorous American and European noise emission standards, providing superior EMI and RFI protection to prevent interference with modern electronic controls. This direct-fit replacement ignition transformer features a single porcelain design and side bracket mounting, allowing for a seamless swap-out during routine maintenance or emergency service calls. It effectively replaces the Webster 3-32AB-BAF, offering the robust 120Vac performance contractors expect in the field. Note that this specific 658 type is dedicated to the AFII series and will not fit Beckett A, AF, or AFG burner housings.

Key Benefits for Contractors

• Precision Compatibility: Specifically designed as an OEM-grade replacement for Beckett AFII burners and Webster 3-32AB-BAF units.
• Enhanced Thermal Regulation: Integrated high-temperature wiring allows the unit to run cooler, extending the service life of the ignition system.
• Superior Suppression: Advanced engineering provides excellent EMI and RFI protection, ensuring no signal disruption to nearby burner controllers or home electronics.
• Reliable Arc Strength: Delivers a consistent 10,000V arc even in cold-start conditions, reducing lockouts and call-backs.

Common Questions

Will this transformer fit a Beckett AFG burner?
No, the 2741-658 is specifically manufactured for the Beckett AFII. For Beckett A, AF, or AFG models, you typically require the Allanson 2721-628G.

What are the primary electrical requirements?
This unit operates on a 120Vac supply voltage (60Hz) with a 250VA power rating and provides a 23mA output to the electrodes.

How do I test if this transformer is failing?
Technicians should perform a spark gap test (drawing an arc of at least 1/2") or use a specialized tester to verify the 10,000V output across the high-voltage terminals.
