Metal Stud Framing/ Wood Burning FP Flu
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
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.
- What "Dura-rock" or cement board material should we face the inside of the "Alcove"?
- 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.
- Ceramic or Dura-Rrock screws? for fastening this material to the metal studs?
- Should we "Dbl. this Material?Ceramic or Dura-Rock screws? for fastening this material to the wood studs?
- Is a Double layer required?
- 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.
- Is another firebox required at the ceiling level?
- If so...unlike the lower Fire-block, can the upper be Sheet Rock or plaster Board
