Allanson 2721-620 Transformer

The Allanson 2721-620 is a heavy-duty oil burner ignition transformer engineered specifically for Wayne E burners. This industrial-grade unit operates on a 120Vac primary supply, delivering a consistent 10,000Vac secondary voltage at 23mA. Designed with a mid-point ground configuration, it ensures stable arc performance and efficient combustion in demanding heating applications. Unlike solid-state electronic ignitors, this traditional ferro-magnetic transformer provides superior resilience against voltage surges and harsh ambient conditions commonly found in mechanical rooms. Its specialized housing ensures a precise fit for Wayne E series burner housings, maintaining the critical electrode gap for reliable cold starts. For service technicians, the 2721-620 is the standard replacement for restoring OEM specifications to oil-fired appliances, offering high-voltage ignition stability and a long duty cycle under continuous operation. Use this component to resolve frequent burner lockout issues caused by weak or intermittent spark output.

Key Benefits

• OEM Compatibility: Precision-engineered for a drop-in fit on Wayne E burners, reducing installation time.
• High-Output Performance: Constant 10,000V secondary output ensures positive ignition even with heavier fuel oils.
• Industrial Durability: Traditional iron-core design provides excellent heat dissipation and electrical noise suppression.
• Stable Arc: The 23mA current rating and mid-point grounding prevent electrode fouling and intermittent spark failure.

Common Questions

Does this transformer replace electronic ignitors?
This is a ferro-magnetic transformer. While it can often replace electronic ignitors in the same physical footprint, check your specific mounting plate and clearance requirements for the Wayne E burner.

Why is my transformer clicking but not sparking?
If the 120V supply is present but the 10,000V output is weak, the internal windings may be compromised. Ensure your primary connections are secure and the electrodes are properly gapped.

Is this unit compatible with other Wayne series?
The 2721-620 is purpose-built for the E series. Verify the mounting bracket and terminal configuration if attempting to use it on M or Blue Angel series burners.
