I recently installed a wood stove and routed the stovepipe out the back of the stove, into the existing masonry firebox, through the smoke chamber, and up through the existing clay liner. I first connected some straight sections of pipe and dropped them in the chimney from the roof. Then I went inside and connected my elbows with sheet metal screws and furnace cement. Next I stuffed around the old fireplace damper location with Thermafiber non-combustible insulation. I set the stove in place and connected the increase off the back of the stove from 5" to 6". I measure the last piece of straight pipe and went to connect from the increaser to the bend coming out of the smoke chamber and realized all the pipe installed in the chimney was backwards, so I was left trying to connect 2 female connections. I then took the straight piece and sort of crimped it so I had 2 male connections, screwed it, and furnace cemented it together. Is this type of connection acceptable? Is the orientation of the stove pipe important, ie female connections towards the stove or male connections towards the stove?
