Allanson Transformers 1092-K Transformer

The Allanson 1092-K is a heavy-duty ferromagnetic ignition transformer engineered specifically for high-demand gas burner ignition systems in commercial and industrial settings. Designed to meet the exact specifications of original equipment manufacturers like Dunham-Bush and Iron Fireman, this unit delivers a reliable 6000V secondary output from a standard 120V primary source. As a constant duty transformer rated at 150VA, it is built to provide a continuous, stable spark without the thermal degradation often seen in light-duty residential alternatives. Constructed with high-temperature internal wiring and a single porcelain insulator design, the 1092-K runs cooler and quieter, ensuring longevity in high-ambient environments. This Type K ignition transformer features a one-end ground configuration and superior EMI/RFI protection, meeting both American and European standards for suppressed electrical noise. For veteran techs, this means cleaner signals for flame safeguards and reduced interference with nearby control logic. Key Benefits

• OEM Compatibility: Precision-engineered for Dunham-Bush and Iron Fireman gas burners.
• Industrial Grade: Constant duty 150VA rating ensures reliable operation in high-cycle industrial applications.
• Low Noise: Advanced EMI and RFI shielding prevents interference with sensitive burner controllers.
• Thermal Efficiency: High-temperature wire and optimized core design minimize heat buildup during extended run times.
• Standardized Fit: Standard Type K mounting and internal junction box simplify field replacements.

Common Questions

Can I use the 1092-K for oil burner applications?
This specific model is engineered for gas ignition. Always verify the secondary voltage and mA requirements of your burner’s electrodes before attempting to cross-reference with oil systems.

How do I test the secondary output on this one-end ground unit?
Use a high-voltage probe to check for 6,000VAC at the Rajah terminal. Ensure the transformer case is properly bonded to the burner chassis to complete the ground path for a valid reading.

What causes these transformers to hum or overheat?
Excessive secondary resistance, often caused by GTO leads exceeding 8 feet or improper spark gaps (should be 1/8” to 3/16”), can lead to saturation and overheating.
