Fenwal 05-129865-060 Wire

The Fenwal 05-129865-060 is a 60-inch heavy-duty high temperature ignition wire engineered for critical spark delivery in industrial and commercial heating systems. Designed for use with direct spark ignition (DSI) modules, this high voltage ignition cable features a low-resistance copper conductor to ensure maximum energy transfer from the control board to the electrode, even over extended spans. This HVACR replacement part is built to withstand extreme thermal environments, rated for operation in temperatures up to 200°C (392°F). Its 18 AWG construction and high-grade insulation provide the dielectric strength required to prevent voltage leakage and ensure a reliable, clean spark every cycle. This Fenwal ignition wire is an essential component for maintaining consistent burner operation in large furnaces, ovens, and boilers where clearance and cabinet layout necessitate a longer 60" lead without compromising signal integrity or flame sensing capability.

Key Benefits:

• Maximum Spark Energy: Features a low-resistance copper conductor specifically optimized for carrying 15K to 25K volts of spark energy to the ignition electrode.
• High-Thermal Durability: UL/CSA listed insulation protects against degradation in high-heat zones near burners and combustion chambers.
• Extended 60-Inch Reach: Provides the necessary length for large-scale appliance configurations and complex HVAC controller layouts.
• Reliable Flame Monitoring: Maintains stable conductivity for remote flame sensing applications, reducing nuisance lockouts in industrial equipment.
• Secure Connectivity: Compatible with standard terminal configurations found on Fenwal 35 Series and similar DSI gas ignition controls.

Common Questions:

Can I cut this wire to a shorter length if needed?
While the 05-129865-060 is factory-terminated at 60 inches, it is standard practice for technicians to utilize the full length or select the specific length required. Modifying the wire requires proper field termination with compatible high-voltage connectors to prevent arcing or loss of spark energy.

Is this wire compatible with other ignition brands?
Yes, as long as the terminal ends match the electrode and ignition module specs, this high-temp wire functions as a universal high-voltage lead for many gaseous fuel applications requiring 600V rated ignition cables.

How do I ensure I get a consistent spark over 60 inches?
For lengths exceeding 36 inches, verify that your ignition control provides sufficient output. Copper conductor wires like this one are the professional choice for longer runs because they offer lower resistance compared to suppression-type (carbon core) wires.
