Hello! Brand new here. I'm hoping someone can help me out. I currently have a wood stove in my family room. It was previously a pellet stove so there is a brick chimney which the pipe vents into. I love the heat and the warmth, but I don't love the big ugly black pipe and the ugly white brick hearth that it sits on. I have dreams of a beautiful stone hearth with fireplace insert. I did a bit of research last year when I started thinking about it, and I was told that my best route to take would be the Northstar made by Heat N Glo. My first question is - should we frame out on top of the existing hearth and then install the Northstar? Or should we rip out the existing bricks/hearth and install the Northstar into the wall? I attached photos of what we have and what I want.
