Mikloy welcome,The first thing I would do is find out why your stove is not drafting properly(crappy chimney or a blockage somewhere),I would not sell the stove yet.
Please tell us some important things about your set up like your chimney(inside or outside the house,how big,how tall,how far past the roof is it,and if things are nearby that are taller)how its hooked up to the chimney(flue pipe,any dampers)? and if you are having a hard time explaining something just post a pic of it(we love pic's
) so its ease to see and I'm sure this forum can get you going again. Give it time we just need more info. Keepaeyeonit
