Some progress pictures... First one shows the Hearth being built, second the funky venting scenario I have going on... Too bad this was not a top vent stove.. But these pieces were free. It would cost an arm and leg to redo the whole thing with 45* clean outs and a Baro-damper. I am planning to closely monitor my draft see how it runs for the first few weeks.. And yes CO detectors are a plenty in the house!
