The oil furnace nozzle. How it works 

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!

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.

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

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.

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

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

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

You bring up a good point, your right, I am new to u tube since moving to florida, more time on my hands.. I could have made good use of u tube, at times, up north, always more knowledge, every one gets stuck once in a while and needs a eye opening. Thanks

Thank you so much! These videos are being a huge help in class!

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.

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!

Not yet. But it is on the list. Grayfurnaceman

Good stuff, nice job, thank you.

You are quite welcome. GFM

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

Precisava ver este vídeo, muito instrutivo.

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.

THANK YOU

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

bought new thermopride in 09.....keep oil line warm, keep oil filters very clean, use in line tiger loop...after 4 seasons still burns clean, oil consumption good, chimney shows no smoke...does all this tell "the story"?..very curious to pull burner gun, but a little scared....how long can nozzle and electodes last in well maintained system?...great videos....thanks

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?

A Good video.

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.

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.

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

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??

what happen if you touch the bronze filter??

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.....

Would have been great to show how to separate the filter from the nozzle

Do you have a vid on Aquastats?

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.

I have a monarch F-80 Nozzle .85 80AR I cant find new one What would you recommend Thanks in advance...

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....

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

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

Need help fast : My Becker AF-15 don't start on its own .I got to bleed it every time I want heat. Then it seems to run fine? What to do ,, My family is cold !!

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.

what oil pressure required to this type of nozzle to work?

I don't see why not. GFM

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?

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?

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

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

It’s too bad I just learn this when I had to do a service call now I know for future use cost me $130 dollars for a service call now I know how to do it

I have a whole box of brand new ones

just a bit over cautious with the nozzle handling pal. of course you can handle them

What can you use to clean these?

How to clean and re install this nozzle ....

Mrairshot when it says 1.00 that is the firing rate at 100 psi

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

Drinking game! Take a shot everytime he sez "thing" !!

Sir watching from Philippines.. Ahm sir when can we use (1.00,80°A) nozzle or .60 nozzle.. I mean..,we can use any of that size sir even big or small boiler..or it depend of the range inside!!. Thank you sir waiting for your response.

are these worth anything

if oil is going through it i dont see how your fingers could contaminate it

Where does it say in the manufacturers that you can't touch the bronze filter oil came from the ground still has dirt in it prove me wrong

As a service man for 35 years, working for major service oompanies, Long Island, ny, it scares me the number of do it your sellers, they don’t realize the many problems they can get into, extreme soot, major oil leaks, chimney fires, etc. not covered by homeowners because they caused the Problem... a little knowledge is a dangerous thing, by the way I am retired 6 years, and have no personnel interest in protecting my job, been there, seen all the above crap.

Oooooooohhh bronze XD

Bullshit!

The most important is how to freaking remove filter from nozzle and you by pass it. If your going to a video makesure its complete otherwise its not worth uploading.
