When should you replace the fuel oil filter?

Replacing the fuel oil filter is essential to ensure the proper functioning of the oil burner system. The correct recommendation is to change the filter when it shows signs of clogging or at least once a year. Over time, the filter accumulates dirt, debris, and sediment from the fuel oil, which can obstruct flow and affect burner performance. Regular maintenance helps prevent issues such as inefficient combustion, which can lead to increased emissions and even burner shutdown.

By recognizing signs of clogging, such as reduced flow or burner failure to ignite, a technician can take timely action to replace the filter, ensuring the system operates smoothly. Setting a yearly schedule for replacement serves as a proactive measure, reducing the risk of unexpected failures during peak operation periods. This approach ensures the longevity and efficiency of the burner while maintaining safety and performance standards.
