Why is it important to regularly check the combustion air supply of an oil burner?

Regularly checking the combustion air supply of an oil burner is crucial for ensuring optimal combustion. Adequate combustion air is necessary for the complete burning of fuel, which maximizes efficiency and minimizes the production of harmful byproducts such as soot and carbon monoxide. When an oil burner does not receive the appropriate amount of combustion air, it can lead to incomplete combustion. This not only reduces the efficiency of the heating system but can also contribute to operational issues and safety hazards. By maintaining the correct air supply, the burner operates at its best capacity, which enhances overall system performance and provides reliable heat output.
