Woodburner with horizontal flu building regs

[yjones]

Hi,
Im wanting to have a woodburner put in an alcove. The alcove space comes up to about chest height. I envisage having the flue running horizontally to the exterior wall and then running vertical above the roof line.
Someone mentioned abut making sure it complies with regs. Ive been reading part J of the regulations, but theres so much there!
If I post some photos and measurements, could anyone spot any obvious failings? Or would a stove shop come out to quote for the installation - and whilst theyre there - be able to tell me how to comply?
Thanks

Are you installing yourself and getting Building Control approval or are you planning on employing a suitably qualified/registered contractor to do the work?

You need, for your own safety, to have the woodburner installed in full compliance with the applicable regulations.

Go to the HETAS web site for reliable and essential advice on selection and then the safe installation of your wood burner.

The manufacturer would tend to specify the fluing requirements.

I wont be installing it myself, Ill get someone who knows what theyre doing to install it.
But I want to know that - before going to a shop and buying one - that the cove is big enough (ie theres enough space top/sides/back) and that I can have the flue going where I want it.

If you search internet for the make/model of the stove you fancy and finish the search text with.pdf, it should find the manufacturers installation instructions.
As woody says, manufacurers specs override building regs but your installer if properly qualified should be able to advise you.

Are you 100% sure of that ?

Building Control Officers have frequently pointed out situtations where if the manufacturer's "instructions" had been followed to the letter then a potentially dangerous hazard would have been created.

Thats what our BI told me but that was regarding clearances and horizontal flues, the latter is what the OP asked about?

Just exactly how long is the horizontal part of the flue; I can't remember the exact allowable distance, but I doubt if it's as far as you want. A horizontal section won't allow the flue gases to rise, so you'd never get the fire going. But you can build a hearth on/in the floor where the flue would exit, and then have the flue going out of the wall at 45 degrees, then you'd need a twinwall flue after that if it's on the ground floor.

This document is well worth reading. Euroheat has ceased trading after 25 years of business.

The manufacturer made the thing so knows how it should work and be fitted. A BCO, not specifically qualified in heating, and applying some generic guidelines can't trump that.

Obviously the impact on other building regulations can be commented on.

Below is my poor attempt at a photoshop rendering of what I want. At the moment there is one window on the right. I want to add another window to the left of the breast. In order to have more light come in the room and to see the views, I want to dismantle the chimney breast. However, I would like to have a woodburner there, so I was thinking of taking the chimney down to about the height of the window sills. (so everything in red would be removed).

So I need to know things like: how much space does there need to be around the woodburner (this will dictate the size. If its going to be really piddly then I may not bother); can I have the horizontal flue or does it need to go up and diagonally (this will dictate how low I can bring the chimney breast); does the woodburner need to sit on slate and does that slate need to protrude (I dont want to trip over the thing everytime I walk past).

I hope that explains the current situation and what Im trying to achieve.

Situations where the alterations to the building structure that are necessary to comply with the manufactuer's instructions would compromise the building's structure can result in the building control prohibiting the installation.

Do you mean like drilling a 120mm hole through a beam for the flue?

Yeah, probably.
