What signs might indicate that the burner nozzle needs cleaning or replacement?

Fluctuating flame quality and incomplete combustion are significant indicators that the burner nozzle may require cleaning or replacement. When a burner nozzle becomes clogged or dirty, it can lead to uneven fuel delivery and inconsistent combustion. This results in a flame that may flicker, vary in size, or exhibit an improper combustion pattern, signaling inefficiencies in the system.

Incomplete combustion may also manifest as an increase in carbon buildup, which can further decrease efficiency and potentially lead to hazardous conditions, such as the production of carbon monoxide. Monitoring the performance of the burner and observing changes in flame behavior is crucial for maintaining safe and efficient operation, making the identification of these symptoms essential for a low PSI oil burner operator.
