Hoping to get some validation that my installation plan doesn't have any direct issues, or there are some suggestions I should take.
Removed a standard wood insert and am installing a wood stove insert, the previous insert utilized an 8" flexable flue through an exterior chimney and comes in at about a 45deg angle from the back. Picture Included (yes I know it needs cleaned bad, I haven't used it). I purchased a Century CW2900 wood insert that has a 6" flue outlet. Reading over the installation instructions it says you cant go lower than 6" but doesn't say you cant go above 6". Reading other threads on this site, it doesn't seem to be an issue going larger unless the manufacturer says specifically not to.
My plan is to use a 6" 90deg single wall flue pipe out of the stove, into a 6" to 8" 'reducer' and then utilize the existing 8" flue. Rivit those pieces together and seal with some high temp sealant. The 90deg will allow for 0-90' bend so it will allow for mating up the angle correctly. I plan to pack insulation just above the 8" flue joint to prevent cold air entering and will utilize some sort of block off plate below that (though with the setup it wont be air tight, likely will slip in after its all installed.
Suggestions or comments? Thanks
