Flue placement for wood stove

[Johnsm1981]

Hopefully the right place to ask. 

looking for the rules and regs on flue location and direction for a wood burning stove I have just ordered.

 

I’ve read the rules on distance from the roof peak but the issue is I have dormers too, which isn’t covered in any examples.

 

On the picture, the yellow dot is where the flue will come out. 
 

ideally I would like the direction marked in green where it follows the roofline at a 45degree angle and then up in line with the dormers. 
 

Or would it have to go straight up as the blue line shows? The height isn’t really an issue but would it have to go higher than the dormer roof line.?

There are HETAS I think and building regulations (gov UK??) Online. It states height above roofline ,etc. That long 45 degree stretch looks a bit unconventional but not sure..

Don't think any of those options are particularly good without an absolute scaffold pole arrangement to stop it moving in the wind.

 

Get a stove fitter in to make sure it's fitted and legal for your home insurance.

 

Right side end wall would be best option where your arm chair is, then through and up the outside wall above the ridge height & well away from openable windows.

I am not an installer but. a couple of things to consider, if the chimney is close to the ridge then it has to be 600mm above it and there is a 2.3m rule - draw a circle around your chimney 2.3m larger than then the exterior of the chimney and nothing should be in that area.

 

Height then I think in this position 600mm above the ridge regardless. I don't think there is a rule for the length of a 45 degree section however the longer you make it the more support you will need and the more disruption to your roof I guess.

 

I would guess that the chimney will have to sit off the tiles to stop anything building up underneath - combustible materials such as leaves and you'd probably need to get up there annually to check and clean anything away as necessary (at the end of autumn?). Not sure on this point but a chimney has to be a distance away from combustible materials - such as the wooden roof joists..... better check that too, not sure how tiles will affect that though.

 

Wouldn't be my ideal placement in the middle of the bifold doors, doors open and you have the stove sat in the middle of an open area when they are open - probably in the summer when the stove is out but any kid running around will love to bum into it and if they are anything like mine were, to use it as a pivot when running around - not sure how often you'd need to get the stove fitter to replace chimney parts.

 

Can you locate the stove to the right of the building - can't tell if there is anything on that side of the building - but then you can have the chimney going straight up to the ridge up the outside wall and use that as a support for any corners you want to use
