Constructing a Hearth for a Hearthstone Phoenix

[Como]

I have a Hearthstone Phoenix to put in on top of a wooden floor. The instructions are vague on the hearth. It will go in a corner, one side is 12" brick covered with plaster, the other Lathe and Plaster.

So as I understand it I can go closer to the brick wall than the lathe and plaster.

For the floor, I like the look of stone/slate, I may use local Lyons Red Stone say 2" thick, may also use it as a wall covering. But 1" thick.

Underneath the stone somebody suggested a product whsoe name I have forgot. Sounded like Ducrock but better insulative properties, Any ideas?

I have 14ft ceilings so no issues there. The chimney opening is about 8ft up, there used to be coal pot bellied stoves in the building, but n those days straight onto wood floors!

Any comments gratefully appreciated.

You want to put 1/2" Micore under the stone, not Durarock.
As far as clearances to the walls go, the manual will tell you
how close you can place the Phoenix. There should be a section which will
tell you single wall connector clearance & double-wall/rear heat shield clearance.

Micore is the best, especially if you want to keep your hearth thin. You can use durock too but you need to figure out what R value you need and then most likely you will need 2-4 layers of durock.

Your owner's manual also allows for the use of an air gap to get the required hearth insulative value. I could not find this micore stuff so I went with an air gap, durock, and tile using steel studs to build the raised hearth.

The phoenix is nice looking stove.
