Beckett Oil Burner Bleed Screw
Problem: “How do I bleed the air out of my Beckett burner oil lines”

Solution: Hit the reset button on the motor while opening the bleed screw on the pump. It is a good idea to make sure you loosen the bleed screw before hand to make sure its not tight, then just hand tighten it, so when you hit the reset button you can just open the Beckett burner bleed screw a half turn and let the air out of the line. The bleed screw is located in the front or the side of the oil pump on the burner.

Problem: “The flame on my Beckett burner is yellow not blue”

Solution: This means that you need to adjust the air intake on the fan. You can do that by adjusting the squirrel cage baffles located on the side of the burner.

Problem: “How do I change my oil filter on my beckett Oil Burner”

Solution: If you need to replace the oil filter on you Beckett burner you can do so by removing the bolt that holds the cover over the filter. Once have removed the bolt you can remove the filter cylinder and then pull the filter out and replace it with a new one.

Solution: If you are a homeowner then its seriously time to call in a heating professional to have your burner cleaned and adjusted. If you are a heating professional and are clueless because you have never really worked on Beckett oil burners then you will need to adjust the flame, air, intake and possible clean the boiler. It might be a good idea to get some kind of factory training.

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.

  1. I have a fairly new beckett burner. It set for a year not being used and when I tried to start it it just hummed. The fan was not turning. after numerous tries it still just hummed to the point of the thermal overload shutting it down. Upon further investigation I found that there is no filter in line and thefilter on the burner is plugged, also the tip. I still don’t think that has anything to do with the motor turning, so I tried to start the motor with the ignighter assembly removed so I could see the fan. It still would not start untill I helped it with my finger then it took off and ran but it still will not strt tuyrning unless I help it strt with a push of the fan blade with my finger. Is it possible that the motor is bad? Is it possible that there is trash in the pump that is restricting the motor??

  2. I’d change the nozzle, pump strainer (filter), and your oil filter. If your getting sludge up at the strainer in the pump and on the nozzle thats definately a problem. Even if your motor isn’t bad thats an issue. Try not to run out of oil because when you do all that sediment gets sucked through the oil line. As far as you having to play with the squirrel cage to get it to run thats either a burner motor or a pump issue. Either one could be seized. if you take the pump apart there should be two bolts holding the pump to the burner itself, take that off and spin the pump. If that spins freely make sure the burner motor spins as freely as the pump. Also check the pvc coupling connecting the motor and the pump. hope that helps a little.

    • Thanks Mike I removed the pump today and it had some sludge in it. I cleaned it up really good and before I reinstalled the pump I tried to start the motor without the pump connected. It still needed somehelp to start. Once it starts it goes fine. Is that box on the side of the motor a capacitor? Would that give the motor a hard time starting??

  3. I have a Becket AFG burner that is only a few years old. While firing it sometimes makes am intermittent metallic screeching noise. I seem to recall it doing it from the start, but it seems to be getting worse. I don’t see any place for oiling the motor. What might be causing this screeching noise?

  4. I have a becket burner, when on prepurge I get drip from the nozzle, I already replace the oil delay valve still no help any suggestions.

  5. I had a sewage backup and the burner was partially under water.After pumping out the water I tested the burner and it fired. After sitting and drying overnight it will not fire. It humms but I don’t hear anything else. Then it trips. It sounds like the pump is not pumping oil and the electrodes are not firing. Any advice?

  6. Is there any online stores where I can get the parts from for my beckett burner. I also want the “hand pump” to push/bleed the gunk from the oil lines. are nozzles generic as long as it meets number. Thanks.

  7. We have a Beckett oil heater that heats the oil for a thermoplastic paint kettle. The problem we are having is, the burner ( diesel fueled ) starts fine and runs for about one minute or so and then the fuel pressure drops off and the the burner just blows smoke of unburned fuel. Then it starts again and runs for a short time and then drops off again, not allowing it to heat the oil properly. We have changed the fuel pump, the controller, and the igniter. the motor on the fan is good as it does not shut off when the fuel pressure drops. The system does have a thermo coupler, whether this might be a factor we don’t know. The model an ASA ( like for steam cleaners and such ). Can you give any ideas we could try to find the problem? Thanks for your reply.

  8. My oil burner will not start when I call it from the thermostat but it will fire when I hit the reset button. It also will not run for the whole cycle and warm the house to temp at that point I have to hit the reset button again.
    What’s Up?

    • your problem is probably not your thermostat. If you have to reset the primary all the time you may have a loose pipe joint and is letting air into the system or possibly a faulty oil pump. Another common problem is a bad coupling between the pump and the motor. this coupling rounds out in the center and does’nt drive the pump causing no oil and no flame.This causes the flame sensor to relay to the primary to lockout.

  9. I replaced the thermostat with a programable one and the fan will not come on in auto position to the mid speed.
    The fan blower motor runs at low speed. When I put the switch to continouse low speed the fan runs.

  10. Oil burner Beckett Furnace will ignite, and will run fine, but sometimes the ignition won’t hold for long and goes out, and then other times it runs fine again.
    What’s happening? Can you tell me?

    • When was the last time you had the nozzle replaced? The nozzle could become clogged intermittently causing a disruption of the oil and the flame to go out which causes it to go into lockout mode

  11. My Beckett burner (AF) is sooting up my entire basement. I just had a technician out to service and adjust it. Before he came, it was making a booming, roaring sound occasionally upon ignition. He installed a new transformer (20KV according to the tech), and the booming stopped. But it still gets soot everywhere. There’s a flap right at the exhaust duct and the wall behind the flap is covered in black. They’ve tried a number of nozzles to get rid of the boom, but the transformer seemed to do the trick. So perhaps my nozzles aren’t the right size? The tech suggested that I break out one of the basement windows to allow air flow to the burner (since my basement is pretty tight.) I have not done that yet, since it seems counter-productive to me to bring cold air into the house to make the heater work properly. As far as I could tell from what he said, the draft up the chimney is OK. Any suggestions (both on the soot and the window thing)? Thanks.

    • Have you cleaned the inside of the boiler? I had the same problem and no fix on the burner helped. Once I cleaned inside, everything was fine. You may be amazed at the amount of junk in there.

      • You need a new technician. More than likely it is an incorrect nozzle size/spray pattern. It sounds to me like he switched from a solid spray pattern(much harder/louder fire) to a hollow spray pattern which is very hard to get a steady flame on. More often than not the condition is from the draft not being set correctly and is causing a very bad flame which would be the reason for the booming and the reason for the soot. Also if he is telling you that you have inadequate air for the burner more than likely he’s correct. Adding cold air to your burner is somewhat beneficial because it is more dense which means you need less actual air to make up enough for your burner to run correctly. You have a flame that is burner at a few thousand degrees so the air temperature going into it doesn’t matter if it’s 30 degrees or 80 degrees except when fine tuning the flame.
