Reznor 257531 Ignition board Kit

The Reznor 257531 Ignition Board Kit is a critical OEM replacement kit engineered to modernize and restore the ignition sequence in gas-fired unit heaters. This UTEC ignition board serves as the direct-fit upgrade for the obsolete 174260 control module, as well as multiple legacy G861KCC and pilot code 71 or 75 series boards. Designed for professional direct spark ignition (DSI) conversion, this kit streamlines HVAC troubleshooting by replacing inconsistent standing pilots with a reliable electronic control system. The package includes the UTEC 1097-B3-2113A board, a high-performance 1097-210 igniter, and specific 5-pin and 9-pin wiring harnesses to ensure electrical compatibility with Reznor FT, SFT, and TRP models. This 24V HVAC control module manages the gas valve timing and flame supervision, preventing unsafe gas accumulation by monitoring the flame signal with 0.50A precision. For technicians dealing with furnace lockout or faulty ignition systems, this comprehensive kit provides the essential hardware to maintain system integrity and burner efficiency.

• Precise Compatibility: Engineered as the official direct replacement for Reznor 174260 and legacy G861KCC-5401 modules.
• Comprehensive Conversion: Includes the UTEC ignition board, specialized hot surface igniter, and localized wiring for a seamless ignition conversion kit install.
• Enhanced Safety Logic: Features integrated flame sensing and automatic gas valve control to mitigate lockout issues and ensure safe burner operation.
• Durable Construction: Built for industrial environments with high-tolerance resistors and relays to handle standard 60 Hz fluctuations.
• Reliable DSI Technology: Upgrades older 71/75 pilot systems to modern direct spark ignition, reducing mechanical failures in high-demand heating cycles.

• What does it mean when the LED diagnostic light flashes? The UTEC board uses specific blink codes to identify system faults such as flame rollout, pressure switch failure, or igniter circuit issues. Always refer to the included wiring diagram for model-specific codes.
• Will this fit my legacy unit heater? The 257531 kit is specifically rated for Reznor unit heaters using 24V controls, including the FT and TRP series. If you are replacing a 174260 board, this is the factory-authorized update.
• Do I need to modify the wiring for a 174260 replacement? While this is a direct replacement, the kit includes updated 5-pin and 9-pin harnesses to accommodate the modern UTEC board architecture.
