Rheem-Ruud 45-21219-82 Ignition Cable

The Rheem-Ruud 45-21219-82 Ignition Cable is a critical high-tension lead designed for precise spark delivery in gas furnace ignition systems. This pro-grade kit features a 90-degree boot ignition cable, engineered for tight-clearance cabinet installations where a standard straight boot would risk arcing or physical interference with the burner manifold. Rated for 10kVAC and 25kVDC insulation, this cable ensures maximum dielectric strength to prevent voltage leakage during the ignition sequence. The assembly includes a 62-21813-01 terminal adapter, facilitating a secure quick connect igniter cable interface that maintains low resistance for consistent flame sensing and ignition. Whether you are performing a Rheem furnace parts replacement or a routine service on a Ruud system, this 31-inch lead provides the necessary reach and flexibility. Utilizing specialized silicone insulation, the Rheem 45-21219-82 is built to withstand high-ambient temperatures near the burner assembly, ensuring reliable continuity and preventing premature breakdown in high-cycle commercial or residential applications.

• Optimized Clearance: The 90-degree boot configuration allows for secure seating on the spark electrode in compact furnace units without stressing the wire.
• High Dielectric Strength: Features an insulation rating of 25kVDC to eliminate electrical arcing and ensure a concentrated spark at the burner.
• Seamless Integration: Includes a quick connect adapter (62-21813-01) for rapid field installation and compatibility with standard control boards.
• Broad Compatibility: Engineered specifically for Rheem and Ruud gas furnaces, ensuring matched impedance for the ignition control module.

Is the terminal adapter included with this part?
Yes, this ignition cable kit includes the 62-21813-01 quick connect adapter, allowing for versatile termination to different ignition control styles.

What is the total length of the 45-21219-82 cable?
The lead measures 31 inches, providing sufficient length for various cabinet sizes while maintaining signal integrity for the HVAC ignition system.

Can this cable be used with both spark ignition and flame sensing?
In systems through-passing signal on a single electrode, this high-tension lead is designed to carry the ignition spark while maintaining the continuity required for a reliable flame rectification signal.
