The AFG Beckett Burner Review


WeT HeaD KnowledgeAFG Beckett Burner has a firing capacity of 0.40 to 3.00 GPH and an input capacity of 56,000 to 420,000 Btu’s per hour. It is recommended that the AFG Beckett Burner use a Number 1 or Number 2 Heating Oil for use in the United States and in Canada; it is recommended that you use Stove Oil or Number 2 Furnace Oil.  Make sure that you read all of the information provided when you get your AFG Beckett Burner.

The electrical information on the AFG Beckett Burner is the Power Supply has a 120V AC with a 60 HZ and is Single Phase. The Max Operating Load is Amps Max; the motor on the burner is 1/7 horsepower, 3450 RPM with a NEMA 48M Frame and has a Continuous Duty Solid State Igniter. Never try to change the design of the burner for installation purposes. By doing so, you may void the warranty and you may compromise the performance of the burner as well. This may result in loss of pressure and damage to the entire system. Every burner comes with an instruction manual, read the manuals so that you can become familiar with the burner. You can read up on maintenance so you can save as much money as you can without spending it on a tech.

Some of the components of the AFG Burner are the Nozzle Line Electrode Assembly, this is a self-centering assembly that brings the oil to the nozzle and it brings a high voltage of electricity to the electrodes. If this assembly is properly used, it can bring you a smoother and more efficient operation. The Drive Motor has a split phase motor that is designed for continuous use. Plus the motor is virtually maintenance free. The Blower Wheel is a brand new design that has a static pressure combustion air starts and a strong wheel made for reliability and strength.

The AFG Beckett Burner is a compact burner measuring, 11-1/2 inches in height, 12-7/8 inches in width and a depth of 6-9/16 inches. The Chassis stats say that by using the AFG Beckett Burner it will reduce any investment by up to 65%, it will reduce storage space by up to 85% with the compact design and it will speeds up service calls. Beckett Burner also manufactures a burner Model AF, these units are similar but it is not recommended that you try to convert the AF to an AFG. By tampering with the burners it will void a UL listing, it will void the manufacturers warranty, you could compromise the burner function and it would increase your own risk of liability. You can have a long lasting life for your burner if you follow the operating instructions as well do some preventative maintenance on the burners as well. Read all of the manuals and service guides that come with your burner and you can have many great years of these burners. 

Here are some FAQ and the AFG Beckett Oil Burner Manual can be found here.

Q) I have a problem with my 6 year old Beckett AFG oil burner in my house. First off, it starts fine but it just doesn’t continue running for more than 15 – 20 minutes. When I noticed the problem, I had to reset it and run it again. Then it goes off again. It seems like it is going into recycle mode or infinite loop of spinning on its own. One thing though, I always had to reset it myself with my hands in order for it to stay on for a while. I tried to change the oil filter from the tank, pump strainer and even pump nozzle but none seemed to work. My fuel pump is A2EA #6520 and I can find the part from the dealer’s site.

A) When the boiler kicks off and begins to run off, it will take 5 – 10 minutes for initial stage. Then it will reach to the operating temperature, and the burner will try to retain that temperature while keeps running with sequence accordingly. Closely watch out for the flame when you restart the sequence and make sure it gets into this initial preparation stage. The other thing is to clear out the fuel line connected along the oil tank and burner. If the pipe is clogged somewhere in the middle, then the fuel will not be sourced as expected thus running out of source of power. Also make sure to check on the tank and pump filter regularly.

  2. Im installing a new afg #2 fuel oil burner. I have a 2 pipe fuel line system the installation guide call for a plug to be insalled in the return/bypass line. i do not have the 1/16 plug i need to know the size of the plug and where do you put the return line.
    PS its cold in ky.

  3. Do you know how long the 1/16 pipe plug would be and dose it have a tappered end. I tried the standard 1/16 pipe plug with the 5/32 allen wrench but it only went in 1 turn.

  4. I have a Beckett AFG and it is just REALLY loud. I have it serviced in the spring and this past spring they tried downfiring the nozzle to reduce the noise and at the time it seemed better…
    Now, However, it seems only louder and seems to run more. We are having it serviced in a week – not sure what we will do. We built the house 5 years ago and it has always driven us CRAZY.
    Any ideas??

    • Hi John,

      Does it sound like the fan blower motor bearings have gone bad?

      I would call whoever is serving it in a week and ask if they can come sooner just to make sure it gets fixed before whatever is making the noise breaks and then you wind up with no heat,

      Just my thoughts, Let me know if you need any other help or have more questions,

      Either way – Happy Holidays!!


  5. Thanks for the quick response,

    I will call the person servicing it – A long Holiday weekend out of town would be the WORST time for something to go wrong with our heating system.
    As far as what it may be? As I stated previously, we have always found it to be lounder than what you would think – even others have commented on it, and I have asked the technician about it (thus the smaller nozzle this past spring). Now, it sounds different, and maybe even a little louder. I notice something different at the end of the cycle as the burner is shutting down (or after it shuts off).

  6. Our AFG burner (installed Oct. 1997) has been extremely noisy of late. Serviceman saw that there was no soot this fall, so did not clean the furnace. Then the device began to run very loud, so he replaced the fuel filter & pump screen, did a CO2 blowback of oil to the tank, cleaned the nozzle, readjusted electrode and porcelain (? can’t read clearly), flushed the assembly…on Jan 11.

    Now, a week later, the roaring noise is back. And lots of soot! Any suggestions?

  7. My Beckett Oil Burner starts and then stops continually and then finally kicks on. Also even when both the two zone thermostats are set to off the baseboards still get warm or hot and we have little or no hot water. I thoroughly cleaned it and replaced the power exhaust vent, I also added a mixer valve because the water in the kitchen was scalding hot. What should the temperature setting on the burner be? I really would appreciate an answer as the burner guy said every thing was fine when the power vent was rusted and rotted out but wouldn’t start it cause he said it was out of code because of the direct vent exhaust.

  8. Can anyone help with this problem?

    I have the following unit: MAKE: Burnham MODEL: Beckett
    SERIAL #: 951030-4502 MODEL: “AFG” Series Oil Burner
    BOILER #: 27112735 DOE HTG CAP MBG = 121
    Steam Square Feet: 379 Steam MBH = 91 Water MBH = 105

    I recently changed to a new local oil company. The new Tech performed an annual maintenance check-up earlier this year. This is not a new unit so it’s been serviced by other local techs. No problems were discovered but ever since his first maintenance check-up – the furnance has an additional muffled rumbling engine noise. Could the new Tech have done something that wasn’t correct? The added sound is like truck engines driving by. No metal clanking just a louder but muffled engine sound. Instead of sounding like a quiet residential furnance – it sounds more like a commercial furnace with greater capacity. I’ve asked him to return several times to remove the engine rumbling sound but he has not been unable to detect a problem. ANY SUGGESTIONS? William -HOMEOWNER

  9. Why does my bath water take forever to heat up (5-10 min) and the sink water in bathroom is fine? What should the gage be set at for the temperature on my boiler? I have a Beckett AFG

    • Hi, Laura. First of all, it sounds like your sink water pipe and the one for bathtub are two separate lines. If they are shared via one source copper pipe, there should be no difference. One thing you can check is to turn on the hot water system and go down to your basement to watch what the burner does. If you see the flame starts to run off and boiler kicks off itself, then it is doing what it’s supposed to do. Do the same thing on the bathtub hot water and examine.

  10. Thank you a lot for sharing this with all people you really recognize what you’re talking about! Bookmarked. Kindly additionally discuss with my web site =). We could have a hyperlink change arrangement among us|
