How Do I Get the Air Out of the Line of My Beckett Oil Boiler?

An oil burner turns oil into vapor or gas and then combusts it into heat. Oil vapor must mix with air in order for combustion to occur. Once combustion does occur, an oil burner can be successfully used to heat a house or room. To provide continually heat, the oil burner must have a continuous supply of both air and fuel. Modern oil burners, including those made by Beckett, use nozzles connected to hoses to deliver just the right amount of vapor to a combustion chamber. If too much air becomes trapped in the nozzle or hose (line), the performance of the oil burner can be compromised.

Instructions

- 1
  Observe the output of your oil burner. If you notice smoke coming out with the warm air produced by the burner, it is a good sign that you have excess air trapped in your nozzle or line.
- 2
  Replace the nozzle on your oil boiler to remove the excess air from the line as it is likely being caused by a nozzle that no longer fits the line on your burner properly. Note the last time you replaced the nozzle and consider replacing nozzles annually as a good preventative maintenance strategy for the long-term performance of your oil burner.
- 3
  Replace the nozzle with a nozzle that is one size smaller or which emits a solid cone spray if you continue to notice smoke coming from your oil burner after installing a new nozzle. Replace the line filter as well to make sure air has not become trapped in between clumps of oil and debris. Clean line filters, changed annually, may help prevent problems from occurring with your oil burner over time.
- 4
  Check all of the flare fittings on your hose (line) running from the nozzle to the combustion tank. Use a wrench to tighten the fittings as loose fittings can cause air to build up in the line and diminish the performance of the burner.
