Repairing a Cuenod Burner: Combustion Accuracy and Flame Control

Cuenod burners are valued for their consistency, but they still rely on calibrated and well-maintained components. A pump pressure drift, an unsuitable nozzle, or a flame detection fault can lead to incomplete combustion, accelerated fouling, or safety shutdowns. Replacing the right part helps restore stable ignition and steady flame.

Cuenod DIFF° spare parts cover the critical elements of the combustion chain: fuel pumps, nozzles, ignition electrodes, transformers, detection cells (photoelectric/ionization), and control boxes. Functional compatibility is essential, especially in safety electronics, to ensure reliable flame monitoring and immediate cutoff in case of an anomaly.

Essential Components for Your Troubleshooting

Depending on the symptoms, the commonly involved parts are:

• Pumps and Nozzles: pressure and atomization. Unstable pressure or a poorly calibrated nozzle degrades combustion.

• Ignition: electrodes and transformers. In case of misfires or difficult startups, the ignition should be inspected.

• Detection and Control Box: flame monitoring and securing the ignition sequence.

How to Identify the Right Cuenod Part?

Locate the exact burner reference and check the original part's reference. Similar components may differ in wiring, type of detection, or pressure characteristics.

Technical Advice: after replacement, a combustion check is recommended to stabilize the flame, limit soot, and maintain efficiency.
