Do you need a bend in a boiler flue?

Legacy_user

Hi!

We had a new ideal logic+ boiler installed 2yrs ago, since then we had our kitchen window replaced from a tilt 'n' turn to a new typical 2 side windows and one fan window (don't know the term).... when we got the boiler serviced last year it seems the boiler flue is now too close to an opening window.

Does the flue have to have a bend in it or can it go from the top of the boiler 90 bend then straight through the wall? This would give us the necessary space between flue and window.

I don't think there is enough room to have the bend go the other side of the boiler so i suppose it would have to be a snorkle type kit outside?

Thank you for your help and sorry for my lack of technical termonology

Do you know the exact model number of the boiler. Many manufacturers have online technical instructions explaining distances and bend placement etc...

To answer your question directly the answer is most likely yes, it can come out the boiler, 90' inside and then straight through the wall.

Are you asking if the flue can go straight up & then have a 90 bend to go out the wall ?
If that's what you mean then yes but you will need a new vertical connector onto the boiler, distance alongside or above the window needs to be a min of 300mm

sorry my explanation is a bit rubbish... At the moment it has two 90 degree bends then it goes straight outside and then end..... What i would probably need is one 90 degree bend from the top of the boiler then straight through the wall and then end

Messaged the plumber who serviced the boiler last year to check

A picture would be helpful but if I'm reading it correctly your flue starts with a 90deg bend to the left/right then a bit of pipe then another 90deg bend out the wall....if that's how it is I don't see why they would of done it like that unless there avoiding something in the wall or the other side of the wall. Otherwise it would of just come off the boiler with a 90deg bend and straight out of the wall, with no need for the additional 90deg bend.

My boiler has a vertical pipe fitted to the top, approx. 60 cm long, then a 90 degree bend, taking it through the external wall, then a typical end fitting outside.

If that's what you mean, its perfectly normal.


But as Alex1983 says, if it wasn't done that way in the first place, perhaps it can't be done now. Is there perhaps a lintel in the way just above the boiler?
