I have bought a new stove which i need to fit to a small chimney (just large enough for the 153m pipe to fit) thats located in the corner of the room. As I live in France I can't ask what parts are needed. The pipe needs to come from the back of the stove to the corner of the room then up to the chimney place. I know I need a 45% angle and a 1m length pipe plus a straight from the back to the angle, but how do I fit these.
There are lots of different parts on sale but I have no idea what I need besides these 3 pieces.
