IMPORTANT NEWS FOR BAXI BOILER INSTALLERS, new flue standards for Baxi and main boilers.

Derek in this video takes a look at the new Baxi/main boiler flue standards which changed 1st September 2021 and sees how it is going to effect gas boiler installers .

Put a POC management kit today on main to get it above 2m high, sounds like I need to go back to put guard on then !! I should have checked I thought I would not need it over the air intake! Cheers Derek

[@YoutubeHero666]

Cheers for the information i did see the addendum they sent out says applicable from 01/09/21. no idea if they are different flues or have just decided its fine now would be nice to know!

[@johnward5006]

Your baxi flue update video prompted me to look into uv stability in relation to powder coated metal flues! Illuminating it was! Basically it goes back to the fact that the flue manafacturers produced a product that was Basically flawed and in the long term was never fit for purpose.

[@oliversoanes2548]

We used to have a baxi solo 2 pf which was taken out for our extension and we now have a Worcester greenstar 27i. The baxi was installed next to the kitchen window. Would that now require a terminal guard

[@tomkatgastraining]

@@oliversoanes2548 needs to be more than 300mm from the opening in the window and a guard if the bottom of the flue is less than 2 meters off the floor

[@themanftheworld8439]

How long (mm) are the screws which are used to attach the elbow to the flue outlet ?

[@paulross8821]

A 2 metre flue. Now that's a good idea. Nice one Derek 👍

[@elwittinio2865]

Nice vid Derek. Next one, cementing in or filler foam flue to seal in the wall. I always cement mine and silicone the inner and outer rubber seals.

[@Hussain-ch3pr]

Wouldn't condensation drip back to the boiler if the fall is towards the boiler?

[@pizzablender]

Yes, it should. Or it would drip outside and form ice hanging from the flue.

[@paulfildes5489]

I have a 17 year old Baxi 100/2 HE Plus bolier that needs a new flue. Do Baxi still make this part or do they have one made to the new regulations that will fit? (Like a multifit?). Thanks.

[@markennyee]

URGENT question for you , I have had my boiler flue that exits the wall outside then an elbow and a straight pipe then another elbow and then the flue end which is angled it goes through my carport roof it was all done by a gas register engineer and has been certificated every year for many years the car port used to be open on 3 sides until they fitted the snorkel type flue and because all the gases go directly out above the roof I closed two of the sides but still has a open full width side is there any valid reason why this type of flue cannot be fitted again if I got a new boiler ? I would very much appreciate your reply 👍👍

[@galaxydave69]

I emailed and spoke to glow worm about extending there flue up externally through a car port roof then a bend with the terminal in and they said no problem just seal the joints I even phoned back to get a different advisor and got told the same thing

[@Sunnyday5276]

Can I fit it myself and get engineer to check it?

[@tomkatgastraining]

@@Sunnyday5276 no the flue is one of the most important parts of a boiler that keeps your family safe so get an expert to fit it

[@colinfleming2244]

Can't see in the video very clearly but doesn't old ones hav that recess water stop on it

[@johnward5006]

Don't get this UV stable thing! Air tubes are , if metallic not at risk of UV degradation but are from corrosion due to atmospheric conditions.(oxidation) 100mm of white bits is OK, exiting the wall, clearing balcony. Assuming flue clears balcony as prescribed, white bits from wall to terminal are OK even if more than 100mm! Clear as mud to me, so I'm either thick or this issue over white bits is yet to be resolved. In my simple mind, any flue, whatever the material should be SUITABLY corrosion and UV resistant for the life of the appliance! The shortcomings of manafacturers flue systems has been an ongoing debacle for too long.Usually the installer is the culprit, when in fact this is only part of the problem. Don't anyone, manafacturers or others deny the issues surrounding this problem have been clarified. From day one flue manafactureres should have produced a product suitable for all reasonable installation scenarios.

[@secondchance4498]

I think it's the paint that protects the "metallic" flue that needs to be UV resistant. If the paint goes/weakens (due to the UV) its no longer protects and the flue can rust.

[@raul835]

Thanks Derek, detailed and perfectly presented as usual.

[@cmurphy6235]

Where can I purchase STAINLESS STEEL WALL MOUNT PIPE HANGER CLAMP - 102-108 mm for BAXI vent for a 1 m vertical exhaust BAXI vent and attach to the wall in two locations? Murphy Builders

[@TheFatneck59]

So what Baxi are saying is that, the coating they were using on their flue systems was not up to scratch and the material that the flue was made of was poor as well and was subject to corrosion when exposed to the elements. Dead useful when it was mean't to be outside in the rain and the UV's. Just saying like.

[@pizzablender]

UK flues are so different from flues in NL. Screws through the pipe are forbidden here, and the preferred material is plastic these days. Also, they are not branded, but universal.

Please... help!!! I have a BAXI lpg boiler, only 3 years old but the problem has been occurring since its installation. I live in a low level, single storey, bungalow style home. Ive had 5 engineer inspections (3 by BAXI, 2 by the installing plumber) because of a very strong, foul, relentless diesel fumes/exhaust smell (weird as my boiler is lpg) that randomly (because of wind direction and strength) comes into my house via the area of the BAXI and its now making me ill; stuffed up head, sore throat, swollen glands, cough, headaches. I was informed by all the engineers that the BAXI pumps out my lpg fumes and draws in 'fresh air' from outside via the flue. My problem is that my neighbours boiler (12 ft away approx.) chucks out the nasty, foul, diesel fumes/exhaust (occasionally smelling suspiciously like neat, unburned diesel oil) which contaminates the so called 'fresh air' being drawn in through the BAXI flue. Please don't say this can't happen because it does. And please dont say my neighbours boiler needs servicing because I realise that but I cant tell them to get their boiler seen to! With back and front doors open plus kitchen and sitting room windows open it still doesn't stop the smell and is obviously a waste of gas especially in winter. I have discovered that, as soon as I can detect it, by switching the boiler off at the thermostat and at the source socket to stop it sucking in 'fresh air', does stop the relentlessness and it dies down... a bit; not completely. But then I dont know when it might be safe to switch it back on again! Something is not right with this system if this can happen and I need it to be fixed. Ive contacted both BAXI (who has said they have nothing to do with the flue side of the boilers!!! 😮) and Ive contacted Gas Safe but neither seem to be interested in the issue and Gas Safe even told me to go to the Citizens Advice Bureau!!!! Really! So following an old principle based on a flue having to be above roof ridge height (which I hope and believe will sort out the problem), I need to know whether I can extend my boiler flue upward (probably by about 1m possibly 1.5m) and point the open end away from my neighbours house to divert the diesel fumes/exhaust smell. I'm just concerned as to whether this can have an effect on 'flue balance' or negatively influence anything internal? Thanks for any reply and input for this problem.

[@tomkatgastraining]

@@seashel54 sorry can’t comment really on something I haven’t witnessed but have you thought about reporting it to your local council. They have the power for situations like this

[@ChrissieSheldon]

Hey! Thanks so much for your reply. I have another engineer coming but if I don't have any joy i'll give the council a go. Thanks again.

[@rayc1503]

Baxi have added uv resistant stabilisers to the powder coating on their flues. This means the white in certain circumstances can be exposed. I received info from Baxi a few weeks back explaining in which circumstances the white can be exposed in. Thanks for sharing as always Derek 👍

[@johnward5006]

Have just researched the effects of UV on powder coated materials, an eye opener! Learn what I've just learnt and you might conclude the manafacturers have been on a journey of discovery! Call me a sceptic, cynical or just a poor soul looking for transparency.

[@rayc1503]

@@johnward5006 Go ahead John, enlighten me 😊.

[@johnward5006]

@@rayc1503 in plain terms, Baxi and others provided an approved flue system that consequently with the passage of time in real time use has proved to have major shortcomings. Maybe Baxi etc. and the various flue manafactures can account for their product long-term shortcomings!

[@henri7753]

This makes no sense to me. Their outer flue is made of metal. Since when did metal need to be UV-stabilised? I always thought the reason for no white showing was to protect the metallic flue from the rain and thus corrosion. Speaking of corrosion, why isn't the outer flue made of plastic? At least there would be none of this corrosion...

[@johnward5006]

@@henri7753 if you google the subject of uv in relation to metal corrosion you'll be as surprised as me.

[@georgerobinson576]

nice one Derek , really well explained , always appreciate the effort your putting in to spread the word.

[@michaeljohnson1006]

To make plastic UV stable they add carbon black powder. That's why u see black plastic on cars etc. You would think they would just add a black push on sleeve over the white!

[@yensabi]

Nice one Derek , it's basically a crock of shit really just a way out for the manufacturer's not producing fit for purpose components in the first place , outer flues should be made from tough uv resistant plastic like you find on a vertical flue , the only good thing that they have done is make a 2m length , it should be 3m really and that would save a lot of hassle , I've always put a locking screw on push fit joints anyway as I don't trust them...... 👍
