TAOLIK, Hi i will post my hearth build pic in a little bit, I built over the wheel well 2x4 frame with spaced apart for heat distribution. Framing in approx. 1 inch from wainscotting on the side wall. I then screwed hardy backer board on (1/2 in), and then put the brick on (concrete) with thin-set followed up with regular mortar mix for 1/2 joints. The stove is anchored by large turnbuckles to eyelets screwed in the frame. The stove is approx. 7 inches away from the brick on the side and back of the stove. The wall behind the drivers seat is open for heat to exchange. With the stove a roaring, I can put my hand on the hardy board between wall or behind the seat and hold it there all day long. In my opinion, the brick in nice to look at vs. steel heat shield and the brick radiates the heat well once warmed up. 2. The chimney is one 4ft class A pipe and adapters from class A to standard 6 in pipe which is approx. 12 in. So my pipe is approx 5ft tall! LOL and it drafts the smoke out perfectly. All i did was cut the hole installed pipe, then installed the Dektite High temp Pipe Flashing seal and screw in to the roof, add the all weather cap and light the fire. I have had 3 big rains and a snow with zero leaks. I have driven 75 mph with this setup with no movement or back-draft. I have gone down the road with fire burned down to coals with no smoke. With regards to chimney covers, do you mean a cloth cover for the chimney itself or the cap? All chimney parts were purchased at Menard's.
