My new pellet stove is gonna be installed this week & was wondering if their gonna have to put up a foot or more vertically once they punch thru my wall to outside or will they just let it stick out a couple inches & put on some kind of cap ? I've seen a couple pics where the soot collected on the side of the house when it was only sticking out a couple inches . I know awesumm has a 3' vertical on his but they tell me it's an extra expense for the venting pipe . Would really just like it sticking out a couple inches with a "snorkel" cap . What'cha all think ? Also, any harm or effect if i just leave the stove running on low constantly ? Thanks people
