I'm installing a wood stove in my basement and hooking it up to the existing insulated chimney. I was going to hook it up with straight run of stove pipe with a 3' piece. Easy, cheap and best draw for the wood stove, right? My father in law argues I should offset the stove to the chimney and put two nineties in to keep more heat in, obviously killing lots of draw in the process. I'm still leaning towards my straight pipe but looking for opinions or other ideas. TIA
