Lochinvar & A.O. Smith 100208618 Ignition Cable

The Lochinvar & A.O. Smith 100208618 Ignition Cable is a critical high-tension lead designed for reliable HVAC spark ignition. As a direct replacement for WRE2200 and WRE2200K, this OEM spark wire ensures consistent electrical delivery from the ignition control module to the spark electrode. In high-efficiency boilers and water heaters, dielectric integrity is paramount; this cable is engineered to withstand extreme thermal cycling and resist voltage leakage that often causes intermittent flame fail ignition codes. For technicians troubleshooting lockout errors, replacing a carbon-tracked or brittle cable with this genuine Lochinvar replacement part restores the precise millivolt signal required for flue gas combustion. Utilizing a factory-spec igniter cable maintains the system's UL certification and prevents the rough starting commonly associated with degraded secondary-side wiring. Ensure a secure, vibration-resistant connection at the electrode to maximize the longevity of the burner ignition system.

• Universal Compatibility: Serves as the exact OEM replacement for Lochinvar 100173086, WRE2200, and WRE2200K.
• Enhanced Dielectric Strength: High-grade insulation prevents voltage arching to the cabinet or grounded components.
• Corrosion Resistance: Terminals are designed to withstand the moisture-rich environments typical of high-efficiency condensing boilers.
• Direct Fit: Factory-terminated ends ensure a snap-lock fit for spark electrodes and ignition modules, reducing installation time.

Can I use a standard automotive spark plug wire instead?
No. This HVAC ignition cable is specifically rated for the continuous high-temperature exposure and specific resistance requirements of A.O. Smith and Lochinvar burner assemblies.

Why is my boiler still showing a "Flame Fail Ignition" error after replacing the igniter?
If the igniter is new, the 100208618 spark wire is often the culprit. Cracks in the insulation or loose terminal connectivity will bleed off the voltage required for a strong spark.

Is this compatible with both residential and commercial units?
Yes, this cable is utilized across various Knight and Armor series models. Always verify your specific model number against the technical manual before installation.
