Thanks for all the help here guys! Got some great info on this site! My new stove is peacefully resting in it's new home, after what I'm sure the stove thought was an "interesting" day! By interesting of course, I mean SCARY! Ripped out the old Heatalator insert fireplace, removed 1/2 of the wall, re-framed it, moved a bathroom vent pipe from below and buried it in the wall, moved the OAK duct and left flush ion the floor for easy hookup and use later if needed, ran new duct from above the stove to the bedroom on the 1st floor below with an inline blower. Ripped out old and installed brand new tripple wall SS chimney. Durarocked, tiled with Silver slate, and finally, hoisted up a Woodstock Progress Hybrid 3 flights via scaffolding and onto a deck, and hand trucked onto the hearth. DONE! The stove is a work of art! She's all together and ready to go, just waiting for an adjustable pipe to make it meet the chimney nicely. Will fire it up in the morning. Before, during, and after pics including the hoist!
