Allanson 2275-653 Transformer

When you're dealing with a no-spark condition on a Weil McLain QB 180 burner, the Allanson 2275-653 Ignition Transformer is the reliable solid-state solution for a clean, consistent arc. This electronic oil ignitor is engineered specifically for the demands of the QB 180 and QB 300 series, providing a high-performance 17,500V secondary output from a standard 120Vac supply. Unlike old-school iron core transformers, this unit is built with a fire-retardant composite housing that runs cooler and provides a massive weight reduction, making it easier to handle during service calls. It features a mid-point ground configuration and comes equipped with 1/4" push-on high voltage terminals for a secure, direct connection to the electrodes. Technicians trust Allanson for its superior EMI and RFI protection, ensuring that the high-frequency ignition doesn't interfere with sensitive boiler controls. Designed for constant duty, the 2275-653 maintains its open-circuit voltage even during brownout conditions, ensuring the oil burner transformer delivers a reliable spark when the grid fluctuates. This unit is a direct replacement for the France 5LAY-32 ignitor and includes all necessary hardware for a fast, professional installation.

• Universal Compatibility: Specifically designed as a direct replacement for Weil McLain QB 180 burners and replaces France 5LAY-32 models.
• Advanced EMI/RFI Shielding: Built-in suppression meets strict noise emission standards to protect nearby electronics and primary controls.
• Brownout Resilience: Maintains a stable 17.5 kVpk secondary voltage even if primary input voltage drops, preventing nuisance lockouts.
• Thermal Management: Operates at significantly lower temperatures than traditional transformers, extending the service life of the component.
• Streamlined Installation: Compact footprint with 1/4" push-on terminals eliminates the need for complex mounting modifications in most units.

Is the Allanson 2275-653 compatible with other Weil McLain models?
Yes, while it is the primary choice for the QB 180, it is also frequently used on QB 300, GO, 66, and 68 series boilers. Always verify the mounting plate alignment before installation.

Does this ignitor replace old iron-core transformers?
Absolutely. This solid-state Allanson 2275 series is the modern standard for replacing heavy, inefficient iron-core units, offering 1/10th the weight and much higher efficiency.

What should I do if the mounting holes don't align perfectly?
While designed for the QB 180, some older brackets may require slight field modification or drilling to secure the base, though it generally fits the standard footprint.
