Boiler flue location

[Azz00]

Evening everyone!
We are planning to move our boiler (registered gas safe plumber will be doing the work, not us).
I am just wanting to see peoples thoughts on the boiler flue.
I have attached a quick screenshot from the Architects plans below. We are wanting to move the boiler into the cupboard just around the corner from where it is now.
Best case scenario is to put the flue straight out the back but, it is just over 400mm from an opening window.
The boiler is an ATAG 28kw combi boiler.
From what I understand, a 28kw needs to be 600mm away from an opening window?
Is there any way that we can make this work?
Thanks!

Flue sideways.

Sorry, I should have mentioned that we didn’t want to put the flue out of the same wall that the doors are on. It is getting clad so we were tying to keep it completely clear and hide the flue around the corner

Well, the architect's plans should show something that works with the flue at the required minimum distance from an opening window !

You'd think wouldn't you?

Tens of thousands of pounds were spent on the drawings for this job and general spec These boilers are in a basement, with no provision for any flues whatsoever.

I’m going to ring the architect today to see what he says. In the meantime, would something like this be acceptable? But with the relevant brand / fitting for my boiler

Has the gas installer visited and seen the proposed changes,if so what was the recommendation ?.

Be better off contacting your gas installer

Tbh,if it was my property i would not want to see my plume from any of my windows. can the boiler be relocated elsewhere

Let us know what the architect says.

He hasn’t only been round to sort a few bits before the main work started. We spoke to him about it at the time but not in depth. He should be getting in touch with me tomorrow.... hopefully.

Yeah fair point. Well I spoke to the architect today who basically just told me that he gasbag always worked to 300mm and for something like this, the plumber should be able to sort something. He did mention maybe using a plume divertor? To either go out and up or point it away from the window. Which sounds like what I linked to earlier?

He did say that the worst case scenario would be to take the flue out of the back wall but I’m really don’t want to do that

Bldg regs approved document J ,page 49 diagram 34 and table, minimum distance from edge of flue to opening window is 300mm if fan assisted balanced flue, 600mm for natural draught bal flue over 14kw. Is your boiler fan assisted balanced flue ?

 

[ianmcd]

from your drawings the distance is min 300mm, yours is a fan flued boiler

 

[Leofric]

'from your drawings the distance is min 300mm, yours is a fan flued boiler ' - it should be a fan assisted flue when drawn at that distance from the opening window but that doesn't mean it is ! Azoo needs to check that.​

Its an Atag 28 KW combi boiler , they dont do anything else other than fanned flue

'Its an Atag 28 KW combi boiler , they dont do anything else other than fanned flue ' - fair enough. ( thought you were saying it must be because it was drawn that way )

if it was balanced flued it couldnt be moved as you cant buy balanced flues any more, couldnt be OF going through the wall like that , could only be concentric fanned flue
