Thanks for the heads up on the length of the HX tube. As we know longer is better. Already installing that lenth of heat exchanger tubing proved problematic. Using the baseline that the A7 install by Xringer I had modeled the HX lenth. The tubing I used is 5/16 od so a little more surface area by a 1/3 and about the same length. The proof will be in the end trial. Xringers A7 was 7Kbtu mine is a little smaller at 5Kbtu.
