Fenwal 05-129887-036 Ignition Cable

The Fenwal 05-129887-036 is a 36-inch high-voltage ignition cable engineered for robust performance in demanding HVACR environments. Designed to deliver 15KV to 25KV of spark energy from the ignition control to the electrode, this 36-inch ignition wire ensures consistent burner lighting in water heaters and central heating systems. Unlike standard retail leads, this Fenwal replacement part features a professional-grade 1/4-inch female quick-connect terminal with a fully insulated design to prevent voltage leaks and ensure peak dielectric strength. Maintaining the recommended maximum 36-inch length is critical for preserving maximum spark energy and operational integrity. HVAC technicians rely on this gas furnace ignition cable for its high-temperature resistance and reliability in high-cycle ignition sequences. Whether you are performing a routine service or a complete system overhaul, this component serves as a direct Fenwal 05-129887-036 replacement for standard direct spark ignition (DSI) setups.

• Maximum Spark Transfer: Optimized 36-inch length ensures the full 15K-25K volt delivery required for reliable HVAC ignition.
• High-Temperature Durability: Engineered with materials capable of withstanding the thermal stresses common in furnace and water heater combustion chambers.
• Professional-Grade Insulation: Features a fully insulated 1/4-inch female QC terminal to eliminate arcing and electronic interference (EMI).
• Universal Compatibility: Designed for seamless integration with Fenwal Series 35 control modules and various DSI heating systems.

What is the maximum recommended length for this ignition cable?
Industry standards recommend keeping high-voltage ignition cables at or below 36 inches, like the Fenwal 05-129887-036, to prevent significant spark energy loss and ensure consistent burner ignition.

Can I use this cable for remote flame sensing applications?
Yes, while primarily used for spark delivery, this cable is technically compatible with systems requiring high-voltage transmission for flame rectification, provided the terminal dimensions match your electrode set.

Does this cable include the silicone rubber boot?
This specific model features a fully insulated 1/4-inch female quick-connect; always verify your specific electrode terminal type to ensure a snug, arc-free connection during installation.
