C-series electrodes (C3G, C5G, C7, C10, C14, C18, C20, C22, C24, C30) are the primary ignition and ionization assemblies for Cuenod burner controllers across small to large firing capacities. NC-series variants (NC4, NC6, NC9) are alternative probe geometries designed for specific burner frame sizes and chamber configurations. Selection depends on your burner model and control system revision; consult the burner data plate or control schematic to confirm the correct electrode family.

Cuenod ionization cables are designated by shielding type (TGF or TEF) and length grade (LG 380, LG 530, etc.). TGF cables are standard single-shielded designs; TEF variants offer enhanced shielding for high-noise industrial environments. Cable length is selected based on control module location relative to the burner. We carry the most common lengths; longer or custom runs require special order.

Electrode replacement is a routine maintenance task for trained burner technicians. The assembly is plug-in; disconnect the old electrode, withdraw it from the probe holder, and insert the new unit. Ensure the cable is fully seated in the control module terminal block. Do not attempt replacement under pressure or while the burner is firing. Always allow the combustion chamber to cool before handling ceramic or porcelain probe components.

Flame-detection faults manifest as lockout conditions on the burner control display—typically a flame-loss code during the ignition phase or during running operation. Other signs include intermittent flame trips, delayed ignition response, or loss of the pilot light. A failed electrode shows visible cracking, heavy carbon fouling, or damage to the ceramic probe. Replace the entire assembly; probe rods are not field-serviceable.

Cuenod electrodes operate in continuous and intermittent duty cycles typical of industrial boilers, furnaces, and HVAC equipment. Probe materials withstand sustained temperatures up to 900–1000 °C in the flame zone, with cable insulation rated for external ambient conditions up to 70–80 °C. Humidity, vibration, and combustion debris exposure are normal; periodic cleaning of the probe surface (with a soft brush or cloth, not abrasive methods) extends service life.

We maintain stock of eight high-use Cuenod electrode SKUs and ionization cables, enabling same-day or next-day delivery to Singapore and regional customers. Technical documentation, wiring diagrams, and compatibility matrices are available on request. For equipment-specific questions, consult the original burner control documentation or contact Cuenod's technical support; We can facilitate that connection if required.
