I will have my Heatilator Constitution wood-burning fireplace installed by a dealer this next week. Note, this is NOT an insert. This is a complete tear-out of a Superior BFR-3875 wood-burning fireplace and chimney pipe!) I will be doing the demolition myself to save about $850.
The questions I have are as follows:
1.) I plan to raise the hearth (under the fireplace) by 6" with 2"x6" and 3/4" plywood. This would raise the total height of the hearth to 6 3/4". Is there any requirement for heat shield or insulation UNDER the unit itself? The dealer stated there is NO requirement for insulation (i.e. Micore 300) under the unit because the Constitution is a "Zero-Clearance" (ZC) fireplace. Is he correct?
2.) Assuming number 1 (above) is OK, I know that I have to build a hearth extension with the minimum dimensions of 20" x 41". I intend to build the hearth extension up to the 6 3/4" height of the hearth (under ther fireplace). What is the BEST combination of material to build the structure (up to the 6 3/4").
3.) I intend to use tile as the vertical surround of the fireplace (and a 60" wooden mantel around the tile). A large section of sheet-rock will be removed during the install of the Constitution. Do I replace the removed sheet-rock around the fireplace that I intend to grout and tile with 1/2" cement board?
I appreciate any comments and/or advice.
Thanks,
kevin
