Flue bracket regulations

[Joef]

The flue runs up from the boiler into the attic. There are then two 45 degree elbows before the flue runs out to the rroof.The flue runs parallel from the boiler to the bit going out of the roof with an angled bit in-between. Where by regs should the brackets go and how many will be needed?

 

[sammathias]

Usually just before it exits the roof I would fit a bracket and probably one in the middle section

 

[Harvest Fields]

I gather your boiler has been turned off? Can you also post a picture of the flue above the boiler please

 

[Joef]

I only went to look at the flue today .It was serviced and the owners were advised to add brackets to bring it up to regs. Whoever serviced the boiler didn't turn it off and allowed it to run as it has been since it was installed a few years ago.

 

[Harvest Fields]

Are you Gas safe registered?

 

[Stu-B]

Naughty service engineer.

 

[Joef]

I'm not gas safe registered. I went to do a few other jobs at the house and was asked about the flue brackets whilst I was there. I said I'd ask and see exactly what needs doing.

 

[Aire]

I'd want 3 clips on that. One before each 45 and one as it exits the roof

Appreciate the honesty. I’m with Craig 3 brackets for me too mate.

Thank you. That sounds like solid advice.

Thanks for the confirmation. Three brackets it'll be then.

 

[ShaunCorbs]

Every meter and every change of direction so at a min 3 brackets required

 

[Stu-B]

Yup, 3 brackets plus i’d be looking to get same manufacturer as flue. That cheeky strap band stuff ain’t allowed.

Who said that it isn’t?

 

[Stu-B]

The gas safe chap said so when my bro-in-law had his first assessment about 8 years ago, vokera compact with a vert flue.

Depends how it is ran. I would never use it. But if it done correctly it should be fine.

 

[Stu-B]

That’s not what he said, plus why would you anyway? Doesn’t give off the right impression in my book, spend a few quid more and the job is bob-on.

Right = Right.

Needs to be manufactured approved method strap banding isn’t

 

[Harvest Fields]

I’m sure I saw a bulletin some where that said as long as it goes around the flue and is tight to opposite beams it is ok. I’m not that bothered anyway as I always use Worcester flue brackets. I was just saying that I’m sure I saw it somewhere.

 

[firemant]

Strapping is not allowed.

You need a bracket on each stretch as a minimum

You also should have a bracket at the top, as it exits, in addition to the others.

So, technically, 4 brackets as a minimum.

The whole structure must be perfectly rigid, otherwise more may be required (speaking generally, probably not an issue in this case)

 

[Harvest Fields]

I do like a good debate

 

[king of pipes]

As above 3 brackets minimum manufacturered by vokera and fitted as MI straighten the flue up repair the roof felt where it passes through the roof . Kop

 

[EvilDrPorkChop]

Also had two Gas Safe inspectors just recently tell me the same thing, Strapping is not allowed and has to be a proper flue clip on every length of pipe. We've always used clips anyway as I hate the strapping so didn't matter, but i've seen many that have been strapped.

My view is that if you go to a job that's old and it's strapped and adequately supported & secure then it's fine. But on any new installations they should be flue clips.

Getting back to the OP, needs 3 clips on that flue.

 

[king of pipes]

No strapping it must be a proper manufacturerd bracket fit for purpose , 4 on this Intergas flue . Tkop

A clip at every joint and where it exits would do it

 

[JohnnyM]

Standards state 1.8 m and any change of direction intervals to ensure whole system is adequately supported.

MIs may say differently though mate and MIs are like God.

 

[JohnnyM]

So they are

 

[Millsy 82]

I always just put on what ever I've been given so baxi supply 1 per length plus 1 for the vertical terminal so I'd put 3 on that if it still feels loose I'd chuck another on.

I always thought it had to be 1 per length and every change of direction but I have no idea where that came from so don't quote me on that as I may of just dreamt that.

And I also thought you couldn't use banding anymore. Was told that by a bg inspector when I subbed to them years ago and also by the gas safe inspector when he saw it on the van.

No they are not. Regs are legally superior to MI’s contrary to the well held assertion.
