I read multiple threads about having vertical piping in pellet stove exhaust pipe. Originally I had a 45 off the back of the stove that went through the outside wall directly next to stove (stove is caddy cornered) and vented through a sidewall down ward type vent. After reading the threads I elbowed up outside and added 5 ft of vertical piping and a cap. nothing fancy, cap looks like a pointed hat with three legs to create a space underneath for exhaust to escape. I did this so if power went out less smoke would get in house. Well i had stove on lowest setting and power went out. I waited to see if I started smelling smoke, before turning on generator, to see if vertical pipe worked. It did not, within a few seconds started smelling smoke in house. A month into season i went outside and about a ten by ten foot section of siding around cap is all sooted over, hopefully it will just hose off in summer. I also notice that i can smell the stove outside now when with the old piping i could not.
So what good did adding the vertical pipe do. I see no difference. and I did not tee to the vertical i elbowed up to it so it would flow better.
