Reznor 100531 Kit

The Reznor 100531 Spark Ignition LP Kit is a critical OEM replacement part designed for field conversion or system restoration of Reznor unit heaters. This liquid propane conversion kit includes a high-performance ignition control module with integrated lockout functionality, ensuring consistent flame rectification and safety during the combustion cycle. Built for industrial HVAC applications, the assembly features a pilot assembly (Q90FF-2), a dedicated pilot shield, and a 120V primary to 35V secondary step-down transformer. This configuration is engineered to handle the higher energy density of propane while maintaining low-voltage control stability. By replacing a standing pilot system with this electronic spark ignition kit, contractors can significantly improve fuel economy and ignition reliability in demanding environments. Every component is precision-matched to maintain the pressure requirements and venting dynamics of Reznor heating systems, providing a seamless fit for legacy unit heater repair projects.

• Fuel Efficiency: Eliminates the need for a standing pilot, reducing gas consumption during idle periods.
• System Safety: The ignition control module features a lockout protective circuit to prevent fuel buildup.
• Complete Assembly: Includes Reznor 257010 ignition control, Reznor 102708 transformer, and Reznor 97535 pilot assembly.
• Precise LP Conversion: Specifically calibrated for liquid propane gas flow and ignition characteristics.
• Reliable Spark: High-voltage electrode design ensures consistent spark ignition even in cold-start commercial settings.

Is this kit compatible with natural gas systems?
No, the Reznor 100531 is specifically engineered for liquid propane (LP) fuel types. Using this kit with natural gas will result in improper combustion and unsafe operating conditions.

What components are included in this conversion kit?
This Reznor 100531 kit is comprehensive, containing the electronic ignition module, a 35V secondary transformer, the LP pilot assembly, and the necessary pilot shielding for heat protection.

Can I install this on a different brand of unit heater?
This is an OEM Reznor part designed for specific series in the Reznor catalog. Professional validation of the serial number and model number is required to ensure proper mounting and electrical compatibility.
