Update... I received my pipe a while ago now, more than three weeks but my stove isn't together yet. When I installed my thimble into the chimney I decided to raise it another 3 inches to avoid an existing seam in the liner. So this meant I needed more pipe. I decided an adjustable 12" piece between the two elbows would work perfect as it would give me some more offset and height.
The reason for the delay is Duravent is sending me the piece I need. When I was trying to estimate the stack up height and offset in my drawing above I called Duravent a few times for more information and the guy I spoke with ended up telling me if I needed one piece to get it to fit right then they would provide it for free. So once I knew I would need the adjustable piece I took him up on his offer. I'm not complaining because beggers can't be choosers but it took a little more than 2 weeks for them to get it in their system to send it. I would give Duravent 4 out of 5 star review. The Engineer I spoke with was really helpful but the customer service rep seemed a little put off when I was asking her questions.
