What a great informative video, I will now look for poor fitting flues whe I am out walking. To my mind they should all be inspected and signed off by regulations.
You said cant use the a flue extender kit to go through a conservatory if the exhaust and inlet are in different places. but can i run both up through the conservator roof on a 90 up then a 90 to level it above the roof so that the inlet and exhaust are both extended to the same place? (using manufacturer lengths and distances etc) Cheers
Derek great video very informative can I ask the section with the flue too near the door opening can this be made vertical and taken 300mm away vertically and be accepted looking to get my boiler moved with extension being built and best place is next to a door but it would be 200mm away horizontally. Thanks keep up the good work 👍🏻👍🏻
Hiya. Can you help please, when windy outside the boiler makes a rumbling noise and my sure it’s when the wind blows over the flue outlet. Can I attach something like a 45 degree bend on the end or is there something else you can use. Thanks
Very informative. How would you get around with building a pergola (with a roof)on top of the exhaust? It will be a 2.5meters length. The gas exhaust is in the middle:(
I'm Not a gas boiler engineer but I'm a Aerospace Defence Hardware verification qualification test engineer, it's always good to know what's right ✅ in the Gas trade & what's wrong an good indication when looking say for a new home 🏡 The only thing I've changed is a water flow switch for a combination boiler of my own, & thermocouple for an old Central Heating & Hot Water boiler 30 years ago, in the end on that boiler it was found that water was coming from the old dicast heat exchanger onto the pilot light, then a Gas engineer was called out to give the old cast iron boiler a good service 👍, They don't make them like that anymore 😅, before that was installed 40 years ago we had the very old cast iron radiators, those were I'm sure recycled by the installer, those would be well sort after including the very wide cast piping that was taken out, Interesting to look at all the systems, I still really like the Viessmann 200W 13 years old still going very well 👍 I see installation errors using 15mm gas pipe but its not far from the Gas meter, & I was informed by Viessmann I would be better to have 22 to 28mm on flow return except near the radiators, they used 22mm to a block then microbore 10mm plastic to radiators, I'm picking up all the best information for the next installation in a new home 🏡 later on
On my Worcester 25i combi boiler My inlet sticks out about 10 inches, the outlet (centre pipe) sticks out about 1.5ft, it's all plastic and I get rain leaking in whenever it rains, how could this be fixed, I wish I still lived in Droylsden I'd be calling you in
at 06:36 the flue is less than 300mm from a window. But that window looks like it is boarded up & so is not an opening window. Does the 300mm have to be applied if the widow is non opening - either boarded up or simply a non opening design?
Can you do a video of poor installs of vertical flues please. And correct way to instal. I’ve seen so many with no clips. Screws and really poor designs thanks
Jon-Paul Ward. Great video Derek! Some shocking flue installations on there. It’s harder to find a selection of different sized bricks to sit the flue on than it is to install the proprietary brackets! What are people thinking?!🙈
If a boiler is already installed in compliance with then current manufacturers instructions (2020), then later the manufacturers instructions change (2023), does the installation become wrong? Is this reportable? The Worcester Bosch 2000 installation instructions changed do we need to report this as at risk for not being as per MI's?
It’s installed to the current regs and MIs so if it’s installed and they change then the appliance would become not to current standards so no need to do anything
Quick question what about when the flue is up high and has to go past the eves. Which is does have to. , The white part will be sticking out to far. What’s your take on that. Because mi say it must go past
@@tomkatgastraining I see, so has long as the boiler is sealed (no gaps whatsoever) for the mouse to enter in the flue, then through the boiler and then into the house, it should be safe to rule out that possibility of mice entering the home that way.
Great training video 👌 I know your focusing on flues, however 13. 35 mins in, the discharge pipe terminates above the flue below which will cause water ingress into the below flue ID flag straight away 🤔 In the years I've been doing this job 28yrs on fact you have to have eyes of a sh_t house rat, To all the begginers in this job " Never get complacent"!!! 28 years in folks and I never think I'm dogs doo daa. REMEMBER the golden rule LAST COMPETENT PERSON 🤔
I wish i could post a pic on here to ask my question ... ive just noticed my flue on my wall sticks out a good 30 cm out and has huge space around the cirlce that was cut out for it and not sealed in ... which i think it should be ?
My neighbors gas flue was emitting flames so I rushed round and found she wasn’t in I turned her gas of at meter, to be safe haven’t heard if it was a blockage or what could be the consequences of this?
9:52 ideal flue 10:44 that is a anothor vokera 12:52 the botton one is a baxi 15:49 that is a balcony but still an ideal 16:33 that's a vokera 19:08 they are both baxis
Another excellent video from yourself Derek, some rough flues connected to the boilers, shocking 😭😭. Its a very good video for us trainees with excellent information. 👍👍😀
If the white section of the flue is plastic and UV resistant, other than being not as visually appealing are there any other risks if there is a small section showing?
Surprised at how much there is to know about these type of flues. A very informative and interesting video. When checking if there is more than 10ppm CO coming back into the room, do you stand at the door with the analyser probe *OR* is there a certain distance from the door you would stand with the probe? Hope this question makes sense. Thanks Derek 👍🏻 Asian Jon. Training.
great vids We undertake several extensions where the boiler flue needs to be extended. The existing pipe will be returned up the wall and out through the roof. Any chance of a vid on this installation because it must be more and more common
Thank you for this video. I have had a problem with my Worcester flue leaking into the boiler housing every time it rains and your point here about taping telescopic flues may be the problem.
The 10ppm reading that changes things from AR to ID sounds strange, wouldn't it change from day to day depending on weather conditions? Also is that test done with the door closed or open? Thanks
All test results are on the day of the test and yes it can pass one day or fail the next that’s why we say at risk meaning it’s at risk of becoming ID as far as the door open and closed if you mean the flue is too close to a door then yes the door is open
Thanks for tge informative video Derek. I have a ideal he18 bolier. On very windy/wet days I get water being driven in through the flue. Is there a guard /cover or anything that can be used to prevent this?
The problem is the installation of the flue it is probably on to steep a fall. There is no guard for this the flue will need installed correctly or do you have a gutter or pipe above the flue leaking or blocked as this can also let rain in
@@tomkatgastraining there's no guttering above flue, its fitted Between the wall and fence where the wind really picks up. It looks fairly straight coming out with no whites showing. Should it angle slightly downward, as it's angled slightly upwards
@@dannybrown438 the angle should be straight on the standard length of flue or to manufacturers instructions. Flues are designed not to let water in even in a storm so without looking at it I am guessing
I've learned more from you Derek than I did at my covid affected course last year!! :) Good lad PS any chance ya could do a air/gas ratio adjustment video with faults, analyser readings, correct tools and process please? Would really help, ta :)
That's good question! I'm sure this was raised back in 2016 about the flue being exposed too much (sticking out the wall) to the elements! Apparently the paint wasn't at the time UV resistant!
Learnt a lot in such a short space. I will say, you do come across as a know it all. I know there are some rough engineers out there but sending content out slating lad's, when the majority (In my opinion) care about there jobs, end result and their customers, is a bit counter productive. Should be helping each other, not slaying each other. There ain't many out there atm and less good ones, so hopefully your next video is less cocky and more helpful. All being said great content 👍

If a flue goes straight up through a roof space, say a porch roof would this also need clips
To hold it in place ?
Hiya. Can you help please, when windy outside the boiler makes a rumbling noise and my sure it’s when the wind blows over the flue outlet. Can I attach something like a 45 degree bend on the end or is there something else you can use. Thanks
Please get a gas engineer to take a look at it. That’s always my advice
Some examples for each of how they could be implemented correctly might have been good.
Thanks for sharing. Very useful collection.

Hi could you tell what test is before connecting open flue appliance to flue. Please
Plumber installed a gas pipe 100 mm next to the flue
Is this OK, thanks
My flue making a whistling noise it’s driving me bonkers 😩
Is there any time that this man is going to say how to do it, instead of showing photo after photo on how not to do it Totally dreadful video
Your videos really bring clarity, can only imagine the work you put in to ensure everything is covered. But big thanks

Some boilers allow white on show some have balcony kits to extend the poc part so follow MIs and no problem 👍🏻
is it normal for water to drip/spit out the flue when the boiler is active? If not does it need immediate attention?
Yes it is normal
Hi Derek, I have a question on flue gaurds if a flue is under the 2 metres and hasn't got a gaurd is it AR?
No ncs
Can mice enter the house by flues?
A mouse can get through a hole bigger than 10mm but if it went into the flue it’s self it would be inside the boiler or the heat exchanger
@@tomkatgastraining I see, so has long as the boiler is sealed (no gaps whatsoever) for the mouse to enter in the flue, then through the boiler and then into the house, it should be safe to rule out that possibility of mice entering the home that way.

First rate video thanks very informative and good demonstration's showing bad practice and how it should be correctly done. Thanks.
How long does it take to fit a gas boiler flue which needs to go through to the outside wall and remove old one
Such clear talk & beautiful explanations.
I love this channel 📺

It could be leaking cutters so check them first
One of the best videos on flues. Thanks alot Derek.
Very insightful, thanks
Top video always clear and easy to watch 👍
Thanks Derek great video 🙏🙏
Water getting into the top of my boiler blowing up 2 fans. any idea?
Is the flue installed to MIs and are there any waste pipes or guttering leaking over the flue
Excellent video Thanks
These are really useful. Many thanks.
You are the best 🌹🌹🌹👍👍👍
16.44 600mm if it is adjacent to an opening, from the side!
Not for every boiler some manufacturers don’t give a measurement some say 1 m and some say 300mm
Great video! 👍🏻Dave T.
