The gasifier has a 6" outlet. The manual says 8" ID HT is best if the length is 20 - 30 feet. Then the manual says 6" ID HT is satisfactory for around 20'.
Suppose I need two 90* black elbows, 3' black, and 20 to 24' of class A HT. Would the 8" or 6" HT be better? Just worried too large might cause creosote, and too small will cause smoke on reload.
