Petef,
To move the pieces, I used a dolly and rolled them from my garage to the backyard. Then it took four of us to lift them. The front piece is the heaviest. Three guys could have done the other pieces.
John,
My plan is to cover the oven with insulation and then enclose it with steel studs and hardiebacker. After that I am trying to decide. I am probably going to do mosaic tile.
Chau,
I am planning the first fire next Monday if I could bet it mortared together today.
