How2Day: Service Tips for Oil Burners

Oil burners and waste oil burners produce substantial amounts of heat. The byproduct is soot. A well-maintained unit will last years without problems. Servicing an oil burner includes daily checks to annual cleanings. The best service tip is to set up a schedule of maintenance detailing the specific checks you need to do and when. The owner's manual for your burner will have the specific methods for inspecting and repairing the various aspects of the burner.

The burners produce a substantial amount of soot and debris. The oil is typically filtered and free of contaminants or debris, but some will get through. You should set up an annual cleaning scheduled for after the cold season. Disassemble the heater by removing the door and shrouds, cleaning every aspect with a wire brush and approved chemicals as necessary. Use a pipe brush to clean out any vents attached to the heater. A shop vacuum comes in real handy when cleaning the heater. The best practice is to start with the visible parts, and disassemble the unit, marking the location of the pieces as you go. You may want to hire a professional to test the unit at the beginning of the cold season to ensure everything is operating properly.

You should do a thorough inspection of the unit once a month while it is in service. Open the door and vacuum out any loose soot. Inspect the burner nozzle. Some nozzles need replacing frequently, especially with waste oil burners. The lifespan of the average nozzle is 3 to 6 weeks. Check the oil strainer, and clean out as necessary. Clean the unit to avoid excessive buildup of soot and debris. Annual cleaning will take care of the substantial cleaning, but a wire brush to clean off visible elements helps to keep the burner operating cleanly.

Inspect the oil tanks and all the feed lines. Fill the tanks as necessary. You want to look for signs of leaks or damage daily. A visual inspection is sufficient. Closely monitor the unit while it is operating to look for signs of pressure leaks. Inspect the area surrounding the heater and remove any flammable materials, such as rags, fuel or chemicals. Do a cursory inspection of the burner nozzle, door and chimney to look for signs of wear or damage.
