- This is a Grant 50 90 boiler, the Jet is a 0.60 60s jet. it is the same procedure for a lot of boilers. This is not a service and it is posted for entertainment purposes only!
Be safe and isolate the boiler from the supply before you start as you could get a nasty shock from the high voltage spark if it comes on.

The easiest way to gauge the electrodes is by using a 3 mm Alan key and gauge the distance from the nozzle with that
Good job, Bootsowen, ...well done for having a go and getting it all back together and working - MOST people wouldn't have a clue - because they are scared off by 'The Professionals'. Got the same boiler...installed it myself -in 1997 - *never checked oil pressure or did smoke test etc., and it ran for 20 years before I needed an oil engineer (pump was on way out). (*Grant test fire them as Riello burners - apparently - need to be set up for each manufacturers' boiler). It cost £950 (new) and a bit of sweat to install...but without paying for an annual service in real terms it's cost me nowt. Cleaning the baffles takes about 15 mins and I've only done it once...and it was VERY simple.
Since I've been a kid I've always serviced my own cars - even replaced an engine...yet most of my friends would say things like: "I wouldn't dare replace my brake pads and discs." I'm now 70 and have just taken my one-year-old car for a service...£215 for changing the oil and filter and £3 for a sump washer. I kept my mouth shut and paid the bill...but when they service manager said: "I hope you like your clean car," I said: "I never clean my cars it wears the paint down. ;-)
Good luck, young un, and long may you enjoy having fun and saving money!!! In my day job I was a photo-journalist so I did need the odd Haynes manual to keep me on the right path! :)
Thanks Bruce. I didn't realise there was paint in there!
Bruce Currie, we share many DIY traits and are a dying breed.
I have just moved into a 17th C cottage that has some unknown Mistral (of Telford) boiler, that even they can't identify. But by chance I stumbled across this video and it looks identical to mine!
May I pick your brains - 4 weeks ago, this boiler, not used for 2 years to my knowledge, was not working, so some random tweaking and oil bleeding it has now been working for 3 weeks, phew!
The only issue remaining is that it starts each time with a loud verrroommm that can be heard quite a distance. It's not a bang like I have seen some oil boilers so I am not too concerned.
However, it could be a simple service/clean/adjustment will address this issue.
Anything you could advise would be gratefully received, even if it's to say that your boiler is loud to start with.
Cheers in advance.
@@dardobartoli Hi Bob, could it be that it is not igniting initially, until there is a good bit of fuel already in there? Are the sparking gaps set correctly. Have a look on the internet for the manuals for the models that I have listed in the description, they are a good place to start for the spark gaps. Also, are the tips of the spark electrodes pointed and clean/sharp? But to be clear, as many of the comments have reassured me, I am not a boiler engineer, so at your own risk!.
@@bootsowen Thanks, this is the first video or anything I can find on a boiler similar and it has given me enough to go and strip it down and at the very least clean it up and identify the state of the parts with a view to replacing if possible still.
Mistral were a waste of time for identifying their own stuff for sure.
Thanks again.

Very well documented and well explained example of how to complete this work. Will be having a look at my boiler at weekend, not exact same spec, but you gave an excellent overview of the main components. Many thanks!
Thanks, Have a look at the other comments, oil engineers hate this video so take it with a pinch of salt. This worked for me, but whether or not I needed to do it... the jury is still out, I can't tell if there is a difference, but it still works.
Excellent video and very well explained, everything was very clear.
Very well explained great video with your help I fixed my oil boiler. Brilliant.
Excellent
I was just going to get a service man until I seen this video. You just have saved me spending between 100 to 200 euro. This will come in handy for my kids over the Christmas and they will be warm. Thanks for sharing. Off now to buy a new jet and filter and I will clean and make sure everything else is working and set properly like in your video.
You should find the manual for your machine and make sure that you are setting it correctly for your machine, mine may be different. Good luck, let me know how you get on.
@@bootsowen mine is 100% the same as the one in your video 50~90 Euroflame hopefully If i can get the parts today i have it up and running straight away. And if not i have friends working in Grants only 30 minutes away from me.
@@FastNFearless Excellent!
As for the original instructions the jet required will depend on the BTU's of the house but for that boiler its mostly hollow jets.
You did a better job that most places I go.... for real!👍
Thanks buddy. A bit of patience got me there. Doing jobs like this is tedious. I don't think people would do it for money!
@@bootsowen Oh stop man. Some of them can be a nightmare for throwing faults after you have arrived home and something else has failed because of a new part drawing different amps or watts or whatever the fuck. Oh just looking at that boiler gives me flashbacks 😳.
Also I was wrong about what type of jet. They all differ in type per size and model.
Anymore tell them that anything fails and you replace it there is a chance of something else going out. And download the ohms info for each component and check it with a multimeter and the tolerances should be listed so you don't have to go back again. Catch it before it fails and you on another job that you have to drive 15 miles to change a capacitor. Power on buddy.
If I can help anytime hit me up through what's app and if I know the answer I'll be glad to tell you.
Be good 👍
Really like your videos. I know way too little about machinery and handiness myself but really enjoy seeing this stuff.
Thanks, that's cool, that's why I do it! Most of the time I don't know what I am doing but I give it a go. I can always call in an expert. Like that boiler furnace, I think if I called a service engineer they would have said it was too old, just because it would be difficult to do.
Youre an idiot ! That is not the way to do this. how did you set the oil pressure and combustion let alone not changing the hoses cleaning the filters etc, leave it to a qualified engineer !
@@skipup5083
I was told there is not much servicing on a boiler apart from cleaning it out once a year and checking the jet and clearance from the jet to the electrodes.
Outstanding, Very clear procedure well explained
Thanks
Brilliant helpful video,thankyou and cheers.
No problem 👍
Nice video!
Thanks Buddy!
Great job thanks for posting. Amazing how it still works after all this time in a hostile environment!
It just keeps on going.
Hostile environment? 😂🤣😂Ur a drama queen pal
I did this today. On reassembly I sanded the come free of rust and applied copper grease to hopefully aid disassembly next time.
Good man! It is amazing how rough these things can get inside!!
Interesting video. Some useful information there. I see a lot of criticism in the comments from pros. Fair enough if you were claiming this was a full professional service, but it seems all you did was change out the nozzle on your own boiler, as the title of the video states. I suppose the pros are genuinely worried that everyone with a spanner starts having a go, but if someone is competent then I don’t see a problem, especially as it’s your own boiler. Those hoses do look dodgy though 😀. Cheap to replace.
Done the same today 😌 grand job 👌 great video 📹 👍 only different mine still not working running but not firing and idea?
Bleed the pipe going in. Sounds like airlock. That’s the easy one. Or no sparks.
Nice
Thanks
How to clean burner nozzle
I have a Firebird boiler a few years old and has stopped working. Are you near dublin 15.?
I think you need a boiler service person and not a give it a go UA-camr.
I gave my boiler similar to this a good clean,but the smoke is a bit dark and very smelly,would replacing the jet solve my issues?tia
Maybe
You can tuch the nozzle. And the settings are 2 to 2.5mm ahead 4mm apart 5mm up
Thanks, your advice conflicts with the advice I was given. Why don't you post a video?
@@bootsowen
Just got an oil burner installed lately and was wondering has many litres of kerosene would the burner use in a year just as a rough guide.
@@wewouldneversellourclubfor3166 No idea. I put e300 in this one about 8 years ago, and it gets about 2 weeks light work per year. Id say the price of oil has gone up since then.
well i have question ,why i have a smell like diesel car inside house , the burner is in side house in washing machine room (say so)? but never been like this ,why it get so smelly now
If you can smell diesel smoke in your house, I would say that asking UA-cam for the answer is not the way to go! You should shut down your boiler and call a boiler repair person. Ventilate the space, fresh air, shut down the boiler.
Was the boiler failing to fire up on the old jet?
Nope. It was running fine. I was advised to do it and taking it apart piqued my interest. Whether it made any difference from a debatable.
Did you leave the protective cover on by mistake ?
what time in the video?
What made you think the jet needed replacement - just curious
A neighbour suggested it, and I thought, yes, they know what they're talking about. Given that it hadn't been serviced in 10 years and since then I can't tell the difference I'd say they were wrong. Or they averted a ticking timebomb, we'll never know.
Fuckn hell...
Just what I was looking for Owen👍🏻
Genuinely searched what I needed
And first thing that pops up is Joe Murph's mate Owen🤣🤣🤣
Where is this nozzle, my friend?
By all the gods, I think this is the same as the boiler in my new (but old) house, but rebadged by Mistral Boilers. I thought mine was in poor repair but this is worse.
If you're still monitoring this video, would you be able to provide link to where you got specification/manual/instructions from as up till now, I have found nothing.
I will rewatch and try and note all the specific details you list (including brand etc)
On that note, after 'tweaking' the only issue I'm left with is a loud vvvrrroooomm noise each time it starts. Not a bang but it is annoying. If you have an idea as to what this may be, then forever in your debt.
Thanks in advance.
I think that I got the manuals by googling the type of boiler, I think I put the name in the description. I think the vroom may be the gap setting of the spark electrodes. But that is just a guess.
How much should I expect to pay to replace the boiler jet and a service?
I think the jet was about £8.
Any idea on fuel pressure or air volume?
Have you looked at the manual?
@@bootsowen don't have one
How did I miss this vid ?
No idea Tommy, this is one where the comments are wonderful!
@@bootsowen yep, seen that. My gripe is these type of "low efficiancy" good reliable boilers are being ripped out & replaced with so called "High efficiancy" less reliable bs that will have to be replaced sooner & are. Only more efficient when condensing, which in most circumstances is not happening. Yet another eco con job that is in the long-term more wasteful. ... _ _"just just Don't get me started !!!! "
I was listening to "the war and peace report" on NPR rebroadcast on RTE R1 extra yesterday and it was talking about the other side of the COP Glasgow conference. It might help to grind your gears!
I get it that some things are more efficient, but I saw my grandmothers 25 year old perfect oil boiler, that would have seen her out be replaced with a condensing unit. I can see her beating it and it is 2 years old and she 95! She paid for the privilege.
Those 2 spikes are electrodes and u dont need to take all that assembly off 2 change the nozzle just take blast tube off and remove electrodes
Maybe you didn't watch the video?
Also grant boilers require a (h) hollow nozzle not an s nozzle
This was the nozzle specified in the manual for the boiler.
You must also know you didn't take out the baffles and clean them with a wire brush and inside of the boiler with a wire brush then hoovered it out, there are no pipes inside, just baffles to restrict the heat escaping as that area is the primary heat exchanger on conventional boiler and judging by the burner I don't think it was a condensing boiler.
Word of advice.... change the braided hoses just in case they leak all your oil.👍
Ha ha. I know. They come with all kinds of wrong information.
About the EPA is just a mate of mine living in cork had his oil hose leak and it was close to his neighbour's wall and they reported it to the EPA and luckily for him his insurance payer out. But the bill was 35k.
I only trying to help.
In fairness you changed the jet and got that done.. There are a couple of things I would like to bring to your attention.. Them 2 flexible hoses running from the burner to the tiger loop are badly corroded and can leak badly over time and can be dangerous left like that.. Also that thermostat should not lift in and out like that it should be tightly secured in place
So you probably wouldn't like to know that went the unit is frozen and the thermostat kicks in to stop it from exploding I take the thermostat out so that the heat from the boiler has more time to conduct up the pipes and thaw the blockage, Hasn't blown up yet! Great boiler!, The pipes on the other hand...! I must post a video on that thermostat. People here on youtube somehow seem to think that this is dangerous!
You say the thermostat kicks in to stop it which indicates it is still working.. Are the pipes that are frozen lagged? Your best bet is to get a good heating engineer to take a look at it
Do you think a "Good heating engineer" would work on it? You saw the trouble I had to get to the jet. My experience of service people is that they will recommend a new one. Better mark up for them and no hassle.
Nice video, though its a 50/70 not a 50/90
The sticker at the start does say 50/90 but if you go to 12:35 on the video it says 50/70 on the boiler housing. Someone short changed you!
I feel like I have missed the warranty return period!
Wrong jet mate! Also them jets weren't available 10 years so it must have been serviced relatively recently and you can touch the jet just not the filter side of it which is the porous shiny part on the jet. Good job mate but you made it brutally hard for yourself. And one of the most important parts is the oil hose to be changed because they do tend to leak and if that leaks after you did that job and it was reported to the EPA you'd be up s*** creek. PTFE is standing for polytetrafluoroethylene it's not ordering material. And you didn't test any of the components with a multimeter to if any of the electrical components are breaking down or ready to fail example capacitor motor coil control box which contains the transformer for making the electrodes arc for ignition of the atomized fuel from the jet you just fitted but fair play to you I've seen worse
I wonder why the original instructions would quote the wrong jet? As for the EPA: I live in fear.
Couldn't have said it better myself any time I'm on an oil service I always do the basic electrical checks with the components with a multimeter- a must if your an oil/gas engineer in my opinion I dont think I could do my job without it. But always check electric components with a multimeter to see if they are on there way out so you can advise the customer otherwise you will get the dreaded phone call saying "you serviced my boiler a fee weeks ago and now its not working" always cover your back. The same goes for putting a pressure gauge on the pump to see how its working (you can tell by the gauge if it works properly or if the pressure keeps dropping I.e pump on it's way out)
Why on earth did you take the complete head off to change the nozzle ? why did you not just remove the blast tube ?? Also tiger loop should not be within the case . Fire valve ??
Combustion check
Please don't copy what he is doing . HE HAS NO IDEA
Oh yes. It was combustin alright. I took the whole head off because I didn’t know what I was doing. That much should be clear. Also I wanted to be gentle as lots of the fasteners were seized or corroded. I didn’t fit the tiger loop so I can’t comment. The whole thing seems to be working exactly as before. You probably wouldn’t like my trick of pulling out the thermocouple when the pipes to the unit are frozen. Never fails. Not an explosion in sight! The plan is to retire this unit once the oil runs out. But as it is in a holiday home that will take a few years. Thanks. Any tips for next time? Help rather than negative blind questions?
bootsowen Well done buddy. Good video.
To many people Quick to leave negative comments.
Good job.
Thanks buddy
🤣🤣🤣🤣
Boots, with all due respect, that is nowhere near a service for that appliance. You made it so difficult for yourself to change that nozzle too. All you needed to do was remove the two small screws on each side of the blast tube and you have ample access to the nozzle holder.. The blast tube fins should have been thoroughly cleaned with a wire brush before refitting.
The inside of the boiler should also have been cleaned with baffles removed, inspected and any damaged ones replaced. Those flexible houses were well passed their sell by date and should also have been replaced without question. Pump pressure and flue gas analysis should have been carried out to complete the service. A little knowledge is dangerous.
Take it from me on this one, I service and repair these appliances for a living.
Sé mo thuairim é nár thuig tú cad a bhí ar intinn agam a dhénamh sa video seo. Ní raibh aon plean agam serbhís iomlán a dhéanamh, ach an jet a aistriú. Agus sin a rinne mé. Ádh mór!
Thanks for your comment. What field of training are you referring to? Have you made, or can you recommend a video that will make this process clear?
Nothing more than diy nozzle change. Nothing to see here.
@@williammcgrattan9583 It's almost as if I got the title of the video spot on!
@@bootsowen what part of Ireland there?
A bit like all the expert comments on here the "experts" that said not to touch the nozzle/jet because of the oil on your hands are talking bull,
Like yourself I do my own service's and have never had a bother with the burner's performance and always screw them in with my fingers,
By the way you said about installing electric heating in your house in the future any updates on how that's going 👍
Hi there, so far it is not going at all, I haven't started. This boiler is fitted to a holiday house. So it is very little used. So far I am waiting to use up the oil to see how long it lasts. We have been on 1/3 of a tank for the last 3 years, so I can't see it coming anytime soon. But the idea is that because we pay a higher rate for electricity because we use so little, it is maybe worth using more electricity, flawed logic perhaps. In the meantime I have fitted another stove, so the house has 3 woodburners now. I have put the installation in another video. I always find it funny that whenever a video goes up on the internet showing gas or oil work a certain group emerges to say how it has been done incorrectly. Not acknowledging that different parts of the world have different standards. Even the differences between Ireland and the UK are big.
He’s a fool
Jeez mate, You need to change career. You have shown exactly how NOT TO DO IT - you do not need to take the main housing off, just the blast tube. Those flexible hoses NEED changing annually, you should NEVER put old ones back one, they'll split. With all due respect, please dont ever touch another oil boiler.
Good man, you make up for half the sentiment in the comments. Id say you are a certified boiler engineer?
You should take this video down. Its very misleading. And there is gullible people who will watch this and follow your false advice.
You really need to get those flexi pipes changed.
Fair play to you for for trying, but you are way off the mark as regards to service.
We didn't train for years for no reason..
You will have to help me out Declan, what bit of the advice is misleading or false? I replaced a jet. Happy to leave your comment up if it is helpful, but just saying that something is incorrect does not help anyone learn.
A few people have commented on the condition of the flexi pipes.
Have you read the other comments? There is a mix of (presumably) boiler service people who assert that nobody should touch such a complex and dangerous device, and then others who are looking to see what is inside so that they understand how something works.
What did you train as? You don't say in your comment?
Also, I am wary of comments from channels with no content. You could post a video showing the correct way? Happy to put a link here to it.
Dangerous Unbelievable
omg, its a wonder he's still alive. check out my gas videos!
you should not put stuff like this on utube you have no clue about an oil burner you took it all apart to put in an nozzle look up how to service a boiler you will get lots of them on utube
What is your qualification?
