Utica-Dunkirk 14662070 Ignition Control

The Utica-Dunkirk 14662070 Ignition Control is a critical 24V intermittent pilot (IP) module utilized in high-efficiency residential and commercial boiler platforms. This OEM replacement part, also identified by part numbers 146-62-070-70 and 1466207070, manages the sequence of operation for automated burner ignition. It features a specific 5-minute retry function, providing a necessary safety delay and lockout timing to prevent gas buildup after a failed ignition attempt. The integrated dual-function spark terminal streamlines field installations by handling both high-voltage spark generation and flame rectification sensing through a single lead. For technicians troubleshooting intermittent pilot ignition systems, this module ensures precise timing and reliable 24VAC control circuit performance. It is direct-fit for select Utica and Dunkirk gas-fired boilers requiring an electronic ignition module to maintain consistent flame supervision and secondary ignition cycles.

Key Benefits for Contractors:

• Broad Compatibility: Serves as a direct OEM specification for Utica-Dunkirk boiler parts, ensuring correct mounting and terminal alignment.
• Simplified Wiring: The combined spark and flame sense terminal reduces the footprint and complexity of the burner assembly wiring harness.
• Safety Logic: The 5-minute retry logic enhances system reliability while meeting modern safety standards for ignition sequence management.
• Standardized Voltage: Operates on standard 24V HVAC control circuits, making it compatible with existing transformers and gas valves.
• Reliable Flame Supervision: Solid-state internals provide sensitive microamp detection for accurate flame rectification monitoring.

Common Technical Questions:

Can I use the 14662070 to replace older 146-62-070-70 models?
Yes, the Utica-Dunkirk 14662070 is the direct current replacement and is functionally identical to part numbers 1466207070 and 146-62-070-70.

What does the 5-minute retry feature do during a lockout?
If the pilot ignition control fails to sense a flame within the trial for ignition period, it will wait five minutes to clear any unburned gas before attempting the next cycle.

Is this module compatible with standing pilot systems?
No, this is an intermittent pilot ignition module designed for systems that use a spark-to-pilot sequence rather than a continuous standing pilot.
