I'm doing a corner install. If I 45 out of the stove thru the wall the stove has to stick way the hell out in order to get 12" of clearance from the inside corner that is outside the room. ..hopefully that makes sense. I want to push the stove into the corner more but in order to do that I would have to move the thimble (harman direct vent kit) over a stud bay which forces me to use (2) 90s...not a big deal but the harman is pretty vague in the book on how many is acceptable. So here is my venting if I push the stove to were I want it: Duravent Pelletvent pro 3" Out of stove...horizontal... Appliance adapter 45 90 12" 90 12"...thru the wall outside... Clean out Tee...vertical to 18" 90 Horizontal cap Sound ok??? I still have room to get behind the stove if need be. I could eliminate the tee and run the horz cap and then to clean just remove the cap...but I have an inside corner outside and figured I'd run the tee with a short vert to help cut soot down, if any. I'm just worried about the 90s...too close?? Ash catchers?? PIA to clean?? Restriction?? ...??? Best way to get a stove in the corner without going vertical?
