Hi. I've been given the goahead, of sorts, for a man cave, of sorts, in the basement. I need some heat down there. Was thinking pellet stove with vent routed through the wall somehow. -Can the venting be done through the rim joist? My floor joists line up okay in the location I'm thinking? I think I could also go through the concrete. -How far a horizontal run can there be before it starts going up? -How far from an inside oil tank must it be? Thanks for any insights. I realize that I won't tank anything as gospel. Want to look at feasibility. Because of decks and porch and prevailing winds, there seems to be only one wall as a candidate and that wall already has an oil tank, boiler, indirect tank, etc. Might be able to get another flue in the chase, but it'd not be cheap and pipe routing will still have horizontal issue. Thanks again.
