WE are installing a Freestanding Wood Burner in a Corner. We would like to build an Alcove w/ faux rock faux attached to metal stud framing.
Instruction Manual says "Combustible Materials is:
  • 54" above top surface...7' min Ceiling Height
  • 4" Rear Corners to Combustible
  • CL of flu (DBL WALL) 18.75"
  • 9" to rear
  • 15" to sides
  • which makes the CL of Flu (DBL WALL) 17.5 from rear & 27.75 to sides
note: we are planning on a "Corner/ Alcove" setting, where the Freestanding is set in a sort of whole that is surfaced with faux rock, presently a direct vent gas burning FP is there. We have started demo of whole corner because pipe clearances are obviously different as well as chimney flu is straight up & NOT out the wall.

Because home in wood framed walls both int & ext w/ 10' ceiling, we planned on framing using metal studs. We obviously are concerned with Fire codes/ safety.

  1. What "Dura-rock" or cement board material should we face the inside of the "Alcove"?
  2. What thickness is required in order to maintain a strong enough surface to hold up the system required to attach faux rock as well as provide ample protection from heat transference to wood studs in wall and ceiling rafters.
  3. Ceramic or Dura-Rrock screws? for fastening this material to the metal studs?
  4. Should we "Dbl. this Material?Ceramic or Dura-Rock screws? for fastening this material to the wood studs?
  5. Is a Double layer required?
  6. A Fire-block/ Shelf just inside about 12 inches will be used for attaching the Firebox & for carrying the load of the double insulated Pipe.
  7. Is another firebox required at the ceiling level?
  8. If so...unlike the lower Fire-block, can the upper be Sheet Rock or plaster Board
note: We would also like to utilize the heat within the cavity if possible via return air...although concerns about inferential smoke and filters...
