Balanced Flue regulations - for gas fire

callie16v

Hi,
I am installing a gas fire with a balanced flue in an extension. We have built a parapit wall on our side of the boundary fence, about 150mm inside the boundary. I would like to know if it is possible to have the flue terminating out through the parapit wall (facing the neighbours, but still on our side of the boundary) about 2 meters high. the reason I dont want to go up through the roof is that we have velux windows and a valley directly over the fire. any advice would be appreciated.

I think you are referring to a dwarf wall not a parapet. 150mm is very tight for any work to be done (dont forget the plasterer) If its very sheltered in this location and there is no draw on the flue then it wont work which can be dangerous. You could possibly bring the flue out the wall and vertically up to the required roof level.

What makes you think he is refering to a dwarf wal not a parapet?
Sound like it could be a parapet, no reason it can't be

I could be completely wrong, but it just didnt make sense that it would be a parapet unless there is a flat roof and the op states that there is a valley and velux above.
I just imagined that the extension wall started 150mm in from, and parallel to, the boundary fence but I could be taking it up wrong.

You are taking it up right, it's a parapet wall with an A roof & valley. its 150 mm in from the boundary fence.
Anyway, looks like we wont be able to get the fire, due to regulations with the flue

why dont you let the flue enter the 'boundary' wall just below ceiling level, and then allow it to exhaust above the parapet on the outside.....
the idea of this is to keep it out of reach from your neighbours....
i assume by your posts that the new parapet wall is going to be the new boundary wall???? is this correct....

once this flue exhausts 600mm away from any opening it should be fine.

Sorry for the slow reply,
the problem with this is that there is not enough room to get the flue up over the cappings that are on the parapet wall, without entering the neighbours property.
