Hello. I am new to this forum. I have heated exclusively with a pellet insert since 2005, but just purchased a Morso 1410 Squirrel. The installation document that came with the stove recommends a minimum chimney height of 16 feet. I am planning to run the flue out the back of the stove, through a combustible wall (will need a wall thimble to allow for proper clearances, I know), make a 90 degree turn, then on a 45 degree angle for 2 feet, then another 45 degree angle to be completely vertical up to, and through the soffit and roof. From the point at which the stove pipe will reach vertical, it is 8 feet to the high side of the roof penetration. I understand the 3foot-2foot-10foot rule. My roof has a low pitch. The chimney pipe will penetrate the roof about 2 feet from the peak. I know I need to be at least 2 feet above the peak, but that is a moot point because adding 3 feet above the roof will be higher than that. All in all, the chimney will only be about 12 feet above the stove using those calculations. Would you add the extra 4 feet? I believe it would mean bracing the chimney because it would be more than 5 feet above the roof line. Thanks for giving me any insight you have.
