Boiler Flue Emissions

I want to attach a pergola of some sort onto the rear of our property covering our patio area. Unfortunately the flue from our bolier is centraly placed.

I would like to know if any heat comes out of the flue, or is it fumes? We intend on putting some sort of sunshade on the pergola, so i need to decide what would be suitable, if at all?

My logic is, with a pergola, we could leave a gap at the wall end, and cover the bottom 3/4 if that makes sense? Unlike an awning which would be attached to the wall, so there would be nowhere for the heat or fumes to dissperse.

Any thougths?

Yes, fumes come out of the flue which are potentially dangerous if they were to get inside the house.

There is normally a minimum specification for the space needed around the flue for the fumes to dispurse.

I suggest you will probably need to consult a CORGI registered heating technician to make sure what you plan to do is safe.

I don't actually kno what a pergola is - so I looked it up. It seems to be some sort of covered walkway - is this right?

Assuming that this is right then it seems more or less comparable to a car port in its physical construction. Why not just call Corgi on 0870 401 2200 and ask for their advice?

see page 10 for a guide on carports and flue siting.

Thanks ormus, but the pdf locked up on page 4, i will try and view the doc again later.

For you to have a better idea, here is a picture http://www.relaxinfranceonline.com/provence/06014d.jpg but the bamboo? would cover the bottom 3/4 of the roof area, this would give room for the flue disperse any fumes i thought.

obviously a very grey area then with a bamboo cover.
the info re carports is a bit vague too. some info says its ok within certain rules and some sites/peeps say never fit a flue under a carport.
