Ok, I am going to go ahead and change from single wall to double wall for my interior pipe. From the stove I rise a little over 3ft to a 90* elbow, 1 ft horizontal and then into my clean-out tee. From there I go 18' straight up the back wall of the house. This seems to have been working fine but since BK recommends the DVL (And I am STILL having trouble with my stove working poorly) I am going to make the move. Here is the question, should I stay with the 90* or change over to 2 45*'s? The problem is that if I move to 45*'s then the first one will be a good bit closer to the stove than the 36" that the 90* is. Right? So, stay 90 or go 45??? Which way would draw best? If I change to 45's I will also be eliminating the horizontal run before the tee.
Thanks,
Jason
