A very general question.
But chances are--- depending on the flue size opening of the furnace, 4 or 5" single wall to no closer than 6" of the ceiling. From there, double wall B Type is required through the ceiling, in the attic area and through the roof at least 12" high.
There is more to this in the code books, but this should get you started.
