I am looking at purchasing an old VC Defiant for a good price locally. It looks like it should fit in the fireplace and protrude out of the raised hearth maybe a foot or so (I have over 18" of space on the hearth). I am looking at installing the stove but maybe or may not be moving next summer, so I did not want to run a liner if at all possible and take the stove with me. With my regular fireplace, getting a draft was never an issue and fires burned hot and fast (if not too fast). Is it possible to run the 7 inch stove pipe or flex pipe above the damper and vent it from there? And I have seen people on here use the micore board to somewhat seal the damper area and run the vent pipe through the center, is this "to code"?
