With help from this forum, I installed an NC30 in the lower-level add-on room of my 2-story (that was once an earth contact). I went straight up through the roof of the 1-story room with 15ft total length.
I used DSP double wall inside. No draft problems during my first season last year, regardless of wind conditions or outside temp. It just works.
