I'm not exactly sure which is the Flue, so please don't laugh. I'm having a Stove style gas fire fitted. The big pipe that comes out the back and goes up is 135mm Dia. (Is this the flue?).
The shiny flexible pipe that comes down the chimney (is this the flue, or is it the chimney liner?) is smaller. Does this mean that this will fit inside the other , or is it meant to be bigger so that it fits over the top? Or.. are they mean to be the same size? Does it matter?
A real live gas fitter is fitting it, I just want to be prepared in case there is a problem, or more cost.
