I am going to install a pellet stove in my home in the next two months. I am trying to figure out my venting situation & wanted to see what my options are. I am going to put the stove in a corner facing the long part of the house but the out side wall contains sliders going out to a deck. the distance between the edge of the sliders & the corner wall is 11.5", I am not sure I can get a wall plate mounted in that tight of a space plus the fact that it vents out to a deck. There is also a vented soffit above the deck that is 8.5' off the deck. Finally the stack would be 42" from the door opening so it looks like I need to go through the roof. I don't mind going through the roof but it looks like it will be 20' of 4" corn pipe to clear the top of the garage roof peak to the right since I am installing a multi fueler. My final option is to go out through the wall 4 feet into the garage which is under a staircase then a 45 or 90 degree out the wall & another 90 degree up for as high as I want to go. None of my options sound pretty good & or easy. The price alone in going out through the roof is about $725 in materials. So venting over the deck isn't allowable correct? I have looked in a few stove manuals & while I don't see it specificaly listed I assume it is generally not a good idea? Please tell me I am missing something.
