Part 1
Excellent video. I'm doing my ACS, and learning alot from you. You're a massive help.
Another quality video! Fueling can be tricky part of installation but you made it very clear 👏 thank you
I did an online flue lesson with Worcester Bosch the other day and the engineer said that be surprised how many engineers out there aren't clued up on building, gas safe and MI regulations. Some of these pics actually made me lol - another good video Dman!!
PS: Plumeing nuisance = ill be using that :P
Can become self employed with video like these LOVE IT
brilliant Derek, almost a 2 cuppa video . amazes me to see such a lot of poor work with flueing ,but hopefully those that care will take inspiration from your knowledge . i will ,thanks
Brilliant depth of knowledge in a concise format
Extant video, thank you Derek

Excellent video, & another brilliant explanation regarding flues. Great knowledge. Thanks Derek. 👍👍😀
Jon-Paul Ward. Another great video Derek, great advice as always. Some of those flues!🙈
excellent video and explanation of the Regs regards to Flues
Another great video with excellent explanation. Thanks Derek 👍😀
Thanks Derek 👍🏻. Lots of information on boiler flues broken down and explained nicely.
Asian Jon. Training.
Thanks Derek super information
Flue in void only Worcester does pls check horizontal flue installation pg 7
So you could use expanding foam inside and possibly outside around the flue pipe provided you finish with a 25-35mm cement to provide the weatherproof status? Why would you direct the flue upwards with that Worcester flue as that allows direct entry for rain?
Another brilliant video. Thanks alot Derek
Fantastic video Derek thanks pal.
Such an excellent video thanks Derek
Just to clarify if you fit a standard horizontal flue on a boiler and you fit a sealing ring on inside and outside but no screws are supplied by the manufacturer they are saying in manufactures instructions that this is OK. But then your saying gas safe want that flue sealing with sand and cement on inside and outside around flue under seals so who's right there then as I was always taught to follow manufacturers instructions that would mean it's OK without the sand cement and just the seals
If gas safe produce a technical bulletin it means their inspectors have found faults with appliances even though they comply with the MIs such as flues being pulled out of the appliances due to just using the seals . So we follow TBs that’s why gas safe produce them.
Thanks for that clarification Derek I will order some screws to carry with me from ideal for screwing there flues together when I am installing a boiler on flats above two storey high the flue goes in from inside with no sand and cement possible on outside so relying on rubber seal against the brick work I will have to put screw there from now on what is the technical bulitan number please. Great channel Derek really helpful I have been doing gas 38 years but like pick up info from guys in the know.
Great video, thanks Derek👍👍👍
I found your video to learn more about plume management because my neighbour’s boiler plume is pointing directly into my yard where I work daily. The neighbours use the boiler very frequently all day long, so the plume is not just a visual nuisance but I’m very concerned about harming my health especially by those NOx gases and nanoparticles I’m breathing in. Also, those whiffs of gas emitted by the frequent switching on of the boiler make me feel nauseous. The neighbour has promised to see to it for months now, and keeps blaming the boiler’s age. Having seen your video, I now fear that there might be no plume kit available for his boiler. If true, then is there really no alternative solution? I cannot work elsewhere and moving house is not an option either.

Pluming good video. Thanks for all you do. Top man.🙌👍🛠
Great video as always please keep them coming 👍 and keep waffling
Great video on your example of the conservatory at 15.00 can you have the in let and out let run out of the roof ? You only say about the inlet being left in as a no go.
Thanks
Yes you can do that but you can’t use a plume kit is what I was on about
Hi Derek. Another great video (parts 1 and 2!).
I'm a sparks by trade but want to know what the correct way is to install a new flue to a new boiler.
I'm getting the so-called professionals in to do the job but have had different stories from different engineers who have visited to quote.
The boiler is currently in the kitchen on the back, cavity wall of the house. The flue goes through the wall where it enters the conservatory and then has a 90 degree elbow which then has about 1.5m before exiting through a multiwall, polycarbonate sheet which is at the side of the conservatory. This was done 20 or so years ago by the guys who built the conservatory and was designed by Potterton for the situation.
There are a number of problems such as lack of brackets, however if the main problems are corrected during the new installation, is it basically ok to have a sealed flue running through the conservatory, provided the POC and air intake exit outside in a suitably safe place?
I will also get advice from the boiler manufacturer, once I have a specific in mind, as per your recommendations. I don't want to waste time on this if it definitely can't travel this route. One engineer said no problem, another said that condensing boilers have hotter gases now(!?) so the polycarbonate would need to be changed and the other said that the boiler should be disconnected but he would just pretend that he hadn't seen it.
I obviously need to choose better heating companies to quote!
I hope no-one thinks that my reference to "so-called professionals" is attempting to put heating engineers down. I think that I have just been unlucky with a couple and they are the minority. You and others like you do everything to ensure that everything is done in a safe and professional manner.
Please keep up the good work. I have enjoyed watching your videos and learning for some time now, even though I won't ever be doing any of the work myself but at least I'll be able to ask appropriate questions of the chosen installer.
Hi David it’s hard to comment on a job I haven’t see the main thing is how close to the combustible material it’s got to be more than 25mm away also if you are thinking of boxing the flue in you will need inspection hatches. Hopefully you will find a good engineer ( there are plenty out there) who will give you the confidence with the job in hand
@@tomkatgastraining Thanks for the very prompt response. That makes sense to me and I'll keep looking until I have the confidence in an engineer. Safety is the highest priority so I want someone who has the same priority and confidence in doing the job (and quote).
I'm looking to local companies and recommendations now as the big internet/tv advertised companies who say "we'll get you 3 quotes" were a disappointment to me.
The last video, flue in a conservatory!!! 😮😮😮😱😱😱 Must have been a non gas safe fella who put that in.
nice one Tom
Thanks Derek great video 🥳
thank you it was really useful!
Great Video
Great video
Many Thanks for that
Great video of you
Thanks
Thanks for great video.
Great vid derek👍 made plenty of notes 😁
5:20 is the flue on the right to close to an opening as that looks less than 300mm?
Impossible to tell from the picture just used the picture to show boundaries and facing terminals
Great video thanks
Great stuff!
Excellent video 👍👍👍👍🇬🇧
Hi Derek great video, 1 question I can find an definitive answer too is are the minimum distance measurements (eg to a window) to the outside of the flue or to the exhaust part of the flue? And in the same vane how does a plume divertor affect the minimum distances?
Plume kit reduces the measurement by 50 % but only if the air intake is a minimum of 150mm and it’s from the side of the flue to the opening
Awesome video 👍
Excellent 👍👍👍✌️✌️❤️💐👍👌
Love it
Thanks Derek. Excellent videos. Have you done anything on the requirements of sleeves for a flue going through a timber frame wall? I'm having a new Worcester 32CDi LPG Compact Boiler installed and our property is timber frame. Does the flue need an additional stainless steel sleeve through the wall to protect against potential thermal damage to the timber frame? If so using a flexible sleeve how should it be sealed at each end?
You will need to speak to the boiler manufacturers about this issue as a lot require different things but as a general rule the flue will require a sleeve when installing in a timber frame
BS5440 is my favourit Standard.
Just, has good info and interesting.
Propper jobs worth!! Ain't i😂?
👍👍
Can you do ones of what different types chimneys look like or do you know where I could see this?
If you look at our channel you will see the videos you need there
@@tomkatgastraining sorry to be a pain but i can’t see any chimney vids?
@@lostinthoughtscalminsilenc8167 check out the flue flow test and spillage videos they are all about flues
What is the significance of having the air inlet and flue exhaust in different pressure systems?
Unbalanced flue system
@@tomkatgastraining I have a flue coming out of a wall, it got picked up on our RICS inspection so they have put an extension on. The opening of the extension is pretty much at the corner of the wall, I imagine it's more exposed to wind/gusts. Whereas the original flue and air intake is further away from corner in between our houses. What can the unbalanced flue system do?
@@lloyd4011 as long as it’s on the same wall and facing the same way it will be fine but if you have concerns get it checked by a competent gas engineer

My god last flu in conservative
Always follow manufacturers instructions. Mi's supersede all BS regs and are almost always readily available. If for some strange reason the Mi's aren't available we look to BS440. Flueing and ventilation are always pretty intensive subjects.
I can't understand why many Rgi's get it wrong. If there's anything goes belly up. It's the installers neck on the line. I take pictures as evidence. If for whatever reason Tom, Dick or Harry decide they want to redirect the flue into the neighbor's loft. I don't want Gas safe putting out a man hunt for me. Time and time again you hear GS prosecuting gas safe members. Mostly due to them being incompetent or their negligent. The main problems I tend to find are with vertical flues. Lack of support or poor joints even incorrect fallback. Some of it outright scary. I question myself how these installers qualified 😳
Rant over, thanks Derek hopefully your time served as an gas engineer and mass of knowledge. Has and will continue to help improve this industry 👍.
Time served as a commercial gas engineer playing around with 10, 000 pound per hour steam boilers and gas ovens that could cook a chicken in 5 minutes. Can’t say your post is a rant it’s just what you come across. Keep doing what you are doing and pass on your skills to others which will make our industry a better and safer trade.💪🏻
The problem is many installations have been done by untrained and non gas registered engineers, I have spent much of my work correcting botched installs. Those done by engineers is clearly laziness.
If manufacture said I could do summit, If I thought it was wrong, I wouldn't do it.
I'm the one who's gonna have sleepless nights if shit goes wrong...not Them
The regs say if the manufacturers instructions are not available follow British standards so even though the manufacturers instructions don’t override the regulations you always install to the manufacturers instructions if you don’t then you technically could be installing it incorrectly
@@tomkatgastraining yeh that’s always been the case hasn’t it?
But if I wasn’t happy , it’s my choice ain’t it, just so I can sleep at night
@@groovejet33 only if it’s the correct choice 👍🏻
