What action should be taken if an oil burner emits smoke?

When an oil burner emits smoke, it indicates that there is an issue with combustion, which can result from insufficient air supply, improper fuel adjustment, or malfunctions within the burner system. The correct action is to perform an immediate inspection. This inspection is crucial because it allows the operator to identify the root cause of the smoke emission and address it before it worsens.

Ignoring the issue and continuing with normal operations could lead to safety hazards, such as fire risks or the release of toxic substances. Similarly, simply increasing airflow or replacing the oil filter without first inspecting the burner may not address the underlying problem and could potentially exacerbate the situation. An immediate inspection provides the opportunity to thoroughly assess the burner’s condition, check for blockages, and ensure that all components are functioning properly, leading to safer and more efficient operation.
