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

Can become self employed with video like these LOVE IT

Excellent video, & another brilliant explanation regarding flues. Great knowledge. Thanks Derek. 👍👍😀

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

Brilliant depth of knowledge in a concise format

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

Another great video with excellent explanation. Thanks Derek 👍😀

Extant video, thank you Derek Mohamed Hassan

Jon-Paul Ward. Another great video Derek, great advice as always. Some of those flues!🙈

Thanks Derek 👍🏻. Lots of information on boiler flues broken down and explained nicely. Asian Jon. Training.

excellent video and explanation of the Regs regards to Flues

thank you it was really useful!

Another brilliant video. Thanks alot Derek

Fantastic video Derek thanks pal.

Thanks Derek super information Flue in void only Worcester does pls check horizontal flue installation pg 7

Such an excellent video thanks Derek

Great video, thanks Derek👍👍👍

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?

Pluming good video. Thanks for all you do. Top man.🙌👍🛠

Great video as always please keep them coming 👍 and keep waffling

Thanks Derek great video 🥳

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

Great Video

Thanks for great video.

Great video

Great vid derek👍 made plenty of notes 😁

Great video of you Thanks

Excellent video 👍👍👍👍🇬🇧

Awesome video 👍

Many Thanks for that

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.

nice one Tom

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

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.

Great stuff!

Great video thanks

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?

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?

5:20 is the flue on the right to close to an opening as that looks less than 300mm?

The last video, flue in a conservatory!!! 😮😮😮😱😱😱 Must have been a non gas safe fella who put that in.

BS5440 is my favourit Standard. Just, has good info and interesting. Propper jobs worth!! Ain't i😂?

👍👍

👍

What is the significance of having the air inlet and flue exhaust in different pressure systems?

Can you do ones of what different types chimneys look like or do you know where I could see this?

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 👍.

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
