The oil furnace nozzle. How it works

[@southwestxnorthwest]

Dude, your videos are incredible! I'm a renter and the oil furnace in my house ran out of fuel a year ago. I added more to the tank, and watched your videos on bleeding the system. It started working again, and then stopped a week later. I started watching all of your troubleshooting videos and did the following: Flushed the fuel lines, removed and cleaned the pump filter, made sure the electrodes were set properly, checked and cleaned the gun assembly, and replaced the nozzle. It turned out the nozzle was clogged, and I saved my landlord several hundred dollars. Man, thanks for making such good videos. Feels pretty awesome being able to fix things on your own like this!

[@grayfurnaceman]

Merry Christmas GFM

[@grayfurnaceman]

Annual service is recommended for all oil furnaces. The use of liquid fuel can plug nozzles and there is always some soot. If you have been changing oil filters that helps a lot. Eventually the electrodes will wear down and the spark gap gets too wide. Check my oil furnace playlist. There are a number of vids on service of the burner Hope this helps. GFM

[@blairdoty5101]

So grateful for your vids.

[@sal98]

I second that.I am a first time homeowner who just purchased my house last year this time and my burner gave me some issues which I am in the process of sorting out, but these video came as a great help in understanding my burner system.

[@connorkurant5799]

Thank you very much for your ever so informing videos, they help me understand more for my fuel oil class than just reading a book. One correction though according to Delavan's Nozzle packet a Type A= Hollow Cone nozzle, Type B= Solid Cone, and Type W= Semi-Solid/Semi-Hollow cone spray pattern. Thank you so much for your videos though they truly help with thoroughly understanding everything.

[@SolidStateH2O]

The tiny piece in the nozzle is called a turbulator, I pull mine out and carb clean it and reinstall! Works great! 👍

[@blackonepac]

Thx alot

[@who8dapple]

After running out of oil and finally getting our emergency refill, the furnace would not fire as usual. I replaced the fuel filter, but frustratingly unable to reignite the furnace. I was lucky enough to find your video tutorials and followed step by step. I checked the transformer, electrodes and fuel gun. The electrodes and nozzle had quite a build up of carbon. I cleaned them up with a copper brush and sprayed them down with a spray cleaner, and decided to disassemble the nozzle. I soaked the nozzle parts in a cleaning solvent but the tip was extremely clogged. Was not worth the time, effort and solvent cost and just bought a new nozzle for $5.00. Reassembled everything this morning and double checked the electrode gaps as stated in your other video. Well, it fired up instantly and bellowed quite a bit of smoke from my previous misfires...thankfully, it was nothing more than 30 seconds of soot that eventually cleared up! Thank you for your amazing video tutorials, it got us back in a cozy temp!

[@grayfurnaceman]

What happens is there is garbage in the oil on the bottom and the top of the level. When you run out, the garbage can get into the nozzle. Glad you got it going. GFM

[@grayfurnaceman]

You can, but as with all nozzle changes, you need to test smoke. This requires a smoke pump. If you dont have one, check your smoke pipe periodically for soot buildup. Also combustion air is very important. Try to set it with just no smoke on top of the flame. Do not put too much combustion air. Hope it helps. GFM

[@mikesquire7731]

A is hollow spray, W is semi solid or general purpose, correct you should replace same to same. Delevan nor Hago says not to touch the sintered filter, that one caught me by surprise. We recommend replacing the nozzle every fall (before use) and every 750 - 1000 hours depending on conditions, bad fuel will destroy the nozzle internals quickly.

[@grayfurnaceman]

We usually consider a minimum of 100# pressure. They are many times set to 140# or higher to better atomize the fuel. Hope this helps. GFM

[@blairdoty5101]

I replaced the fuel pump with a used one on my Beckett and the pressure adj had been tampered with. Got it running but air was smashed up and I am not sure if settings are even close....

Welcome GFM

[@grayfurnaceman]

Nice to know it helps. Thanks for the support. GFM

[@grayfurnaceman]

I try to keep any contamination away from the nozzle filter, as the hole in the nozzle is very small. If you are working on an oil furnace, your fingers are probably dirty. GFM

Excellent! Valuable information at a unbeatable price! THANKS!!!

[@trankt54155]

Thanks. Another great teaching video. I think you can clean it with compressed air and some car throttle cleaner (hexane) and that should remove clogged dirt in there. Also need to wear gloves as so not to introduce any grease from hands.

If you are working on your own equipment, you can certainly clean it. I do not clean but replace it as a professional. GFM

[@anotherbrickonthewall]

Hi again. Thank you again Sir for all the hard work you put into these videos!! I have a nozzle leaking issue that I just can't seem to fix on my oil fired water heater. I tried teflon tape on the threads to no avail. Then I tried yellow tape on the threads and also cleaned the pump screen which was filthy. There was no leak for 2 to 3 weeks. Now all of a sudden, it is leaking again. I keep a clean paper towel on the floor under the burner and check it periodically for oil stains. It was clean up until now. I don't have a pressure gauge, but am currently looking into one. Just can't decide on which one to get. Do you have any suggestions about the leaking nozzle??

[@grayfurnaceman]

+anotherbri You probably do not have a leak in the nozzle threads. Those threads do not seal. The seal is the nozzle flange to the nozzle holder. You may have a seal leak in the pump. You could also have a venting blockage. If the unit "rumbles" on startup, you may have venting or heat exchanger blockage. Hope this helps. GFM

[@sirtubemaster]

@ 4:22 you state that the element should never be touched; what is your thought around not touching it? WHY?

[@grayfurnaceman]

sirtubemaster If you are a service tech working on an oil furnace, you probably have very dirty hands. The orifice is very small. Enough said? GFM

[@sirtubemaster]

grayfurnaceman dang a bit harsh no? just asked; should clarify not to touch with dirty hands then because simply touching the element is doing nothing to it. EVEN with dirty hands there is no real concern unless it is caked on grease.

[@grayfurnaceman]

sirtubemaster If you believe that I have a bridge for sale. Do not touch the filter of the nozzle. GFM

[@sirtubemaster]

grayfurnaceman Well i can tell you i work for the manufacture of that sintered bronze part so i know more than you are thinking ;)

[@RamonPreston]

I take mine apart and clean them with no problem. At $10 a pop I'll take my chances. You can't break broken.

[@grayfurnaceman]

[@dominickmossa5023]

Can you tell me what kind of chimney cap can i use to replace current one. On a Mobile home, on a Beckett Oil Furnace..... Recommend a company

A mobile home requires a specific roof jack from the factory. GFM

[@GreenBullOHWIR]

What's wrong with an oil furnace/stove when it will only stay lit for around 16 minutes? Replace nozzle? Cause we are Freezin' over here! Woot! Woot! ;) Thanks for any help.

[@franklee8166]

just wanted to thank you for all the helpful furnace videos. your cautions and tips really came in handy like loosening both ends of the copper feeder tube so you don't have to bend it. love it. quick question, i replaced my 80 degree nozzle with a 70. you alluded to the fact that this can cause problems. please explain? furnace is running fine as far as i can tell.

[@grayfurnaceman]

Frank Lee The 70 degree is the angle of spray. Usually, the air adjustment will have to be changed and if the smoke is ok, you are fine. Hope this helps. GFM

[@fixitmakeit72]

super videos. I have a spare 20.5 -26.5kw oil boiler that i want to use waste engine oil as the fuel and convert it into a heater for my workshop. I am going to attempt to reduce the oil output and air to reduce the total kilowatts of the appliance to about 4 kilo watts. Do you think that its possible or is there a reason why this simply just will not work.Thanks GFM. olly.

[@grayfurnaceman]

If it uses a pressure burner, lubricating oil will not work. The oil will not separate into droplets. The only way it will work is to preheat the oil, then aireate. GFM

[@zheus1987]

what happen if you touch the bronze filter??

[@z978ady]

Are nozzles all of the same quality as long as exact parts match is duplicated? For example is the home improvement center nozzle as good as Amazon.com as good as Sid Harvey?

[@grayfurnaceman]

I have never heard of a "home improvement" "amazon" or "sid harvey" nozzle. Delevan, Monarch or Danfoss are nozzle brands. I would use those 3 brands as good nozzles. GFM

[@mansoorhayat36]

hi..there...we have yourk shiply series 400 boiler....and we r facing problem from since first day....it is generating a lot carbon.in boiler................plz tell how this problem will solve...? we change ratio of blower air many time his upper limit his lower limit ..but slightly difference come in carbon quantity.....

[@MrAirshot]

thanks for the reply , if i make 5 gallon tank with half full of oil and then pressurize it to 150 psi with air ,and hook up this type of nozzle will it work?

[@badboys4nh2005]

will be ok to change spray nozzle from 1.10-80A to 1.00-80A the reason is because we use 155 galons of oil a month and we cant afford oil. plus air blowing is about 120' from the vents thank you.

[@grayfurnaceman]

Angel L. Rodriguez Matos Reducing nozzle size is one of the first things I did to reduce usage. You will need to adjust combustion air to match. Hope this helps. GFM

[@badboys4nh2005]

Thank u ...so to adjust combustion air to match is the left side of the pump right..they have like numbers right. So I need to open the hole after is on and look for the flame to no be smoking right thank u.

[@aldovanzyl-jackofalltrades8446]

good day, i have watched a bunch of your oil burners videos and, but i need to know how does one build this in a simple way, do you have plans for this....? or is this burner something you bought? I want to use it to heat up water for a boiler. i currently have a holding tank with a tap that drips old oil into a tray and i lite it with an old rag and have placed a small amount of air on the flame but not getting enough energy out of it....

[@grayfurnaceman]

The burner used is a commercial one. Waste oil will not work in this type of burner. GFM

[@aldovanzyl-jackofalltrades8446]

so can you tell me how to use waste oil better and more efficient to make hot water from it....? what setup would you use

[@grayfurnaceman]

Waste oil is a completely different system. There are waste oil burners that look somewhat similar to the burner shown, but they have a preheater for the oil and use a small compressor that blows air across the hot oil to burn it. Not a simple system. GFM

[@demolitionbarbiedoll]

dude! My oil burner has a .06 - 80ES (Extra solid) nozzle ... Can I replace it with a .06 - 80S (solid) nozzle?

[@JustinDesilva]

I'm seeing a Delavan 1.10 80A on our burner and we live in a 1,000 sq/ft 1 story ranch. Is 1.10 gallons per hour high, will a smaller gph reduce the total oil consumption?

[@grayfurnaceman]

You are definitely oversized. I have no info on your location and the energy efficiency of your home, but you would have to be located above the arctic circle to need that size nozzle. I would be looking at more like a .50. GFM

[@JustinDesilva]

grayfurnaceman We’re located in Massachusetts, and have a Beckett burner attached to a Dunkirk boiler, running hot water to 8 cast iron radiators.

[@grayfurnaceman]

Does it also supply domestic hot water? GFM

[@JustinDesilva]

grayfurnaceman Yes, but no large water tank, only a small Watts diaphragm expansion tank.

[@grayfurnaceman]

I would top out at .75. You may need to change the head on the burner for the smaller nozzle. I have never been sorry I used a smaller nozzle. GFM

Brian Beaton I assume you have oil. If you get air as you start to bleed, you may have a plugged line, filter or a vacuum leak in the line from the tank or the filter canister. Hope this helps. GFM

[@grayfurnaceman]

The size nozzle is dependent on several factors. Stack temp is probably the biggest one. With pump pressure right behind. If the manufacturer of the equipment has a recommendation on the model plate that is the place to start. GFM

I highly recommened you guys get an obt to do this work on your furnace. If you do it yourself, you can void the warranty on the furnace, and potentially cause an explosion. Or release Carbon monoxide into your house
