After some doing some research, I have found that you can do a horzontal side vent and then up 5 feet for a pellet stove. I was thinking about installing a second wood stove on an exterior wall of the house and venting it horizontally thru the wall and then up 90 degrees 5 feet for a wood stove. Is this safe? How close can the exterior pipe be to the aluminum siding when going up? What kind of other safey precautions need to be considered? Can I just use the DuraVent GS? or sometjing like that?
