Oil burner oil filters are important to keep trash out of the burner gun and plugging the nozzle. A dirty filter can also choke the system from firing properly by preventing the correct amount of oil flow from reaching the nozzle. Oil furnace oil filters or oil boiler oil filters should be changed on at least an annual basis. More if the oil or oil tank is of poor quality. It is also recommended that the oil furnace or oil boiler be shut down when oil delivery is made. As the oil is pumped into the tank it stirs up trash in the bottom of the tank. If the furnace or boiler is running this trash is sucked into the oil line and goes straight to the filter where it can plug the filter.
A plugged filter inhibits the flow. While the filter may allow some oil to pass it is not enough for proper combustion. This causes combustion problems such as soot which will plug the combustion chamber and build up in the flue if the furnace or boiler continues to run. This will usually require a tear down of the furnace or boiler so all soot can be removed.
