Regular Maintenance Tips:

According to the manufacturer, it is recommended for the owner to hire a service professional to perform a regular maintenance on a yearly basis. It is also strongly suggested not to tamper with or make any incorrect adjustments on the unit, controls and any other critical area and parts by owner’s hands because it could lead into further problems such as asphyxiation, explosion or fire. Always make sure that a qualified service technician starts the work on the jobsite.

This is because operation and adjustment of the oil burner requires many hours of in-depth technical training and skillful use of combustion test instruments and other test equipment, and these could not be easily acquired by regular customer over the books or any other online resources.

However, as an owner of this burner you can do a few basic things before you make a service call:

– Check the outside oil supply line. It is visible and usually transparent pipe, and you can inspect any signs of leakage around the area.
– Also check the oil supply system. All fittings should be leak-tight. The supply lines should be free of water, sludge and other restrictions.
– If you can, verify the nozzle is the one originally specified by the appliance manufacturer.  Sometimes it can result in malfunction or poor performance having the nozzle of different specifications from the same manufacturer.
– Inspect the igniter spring contacts. Clean or replace if corroded.
– Inspect all gaskets. Replace any that are damaged or would fail to seal adequately.

    unit shuts down, blinking green light comes on and I press the red reset button. It will kick on but shut down after a minute or so. Have never had a problem before.
    Had it serviced a year ago and everything was fine.

  8. I had my burner serviced in October and prior to that never had a problem with it. During service, the tech took it apart and removed the side cleanouts (he left the boiler apart for three weeks and it leaked oil into the burner and interior of the boiler had to be replaced). Now I have to reset the oil button about once a week. Once reset it fires up and usually is fine for a week. It’s a Beckett burner.

  9. My Beckett burner shoots the flame out the chimney. This is on my pressure washer. Just started this. What could be the problem
