I am planning to install a Jotul F3 wood stove in front of my existing fireplace. Existing brick hearth pad area is being extended forward. I plan to have the stove sit as far back as possible toward the fireplace opening (but not in the firebox). I have a few questions regarding clearances. Note - the existing brick fireplace surround is 61" from side to side and is a couple of inches proud of the wall. The F3 manual page 12 has information about clearances to mantel and trim. My fireplace surround and mantel is brick only, no wood trim or mantel. a. Do I need to be concerned with the "top to trim" or "top to mantel" measurements since the trim is non-existent and the mantel is brick? The top row of brick extends out 7 inches. It seems to me that these clearances would then not apply? b. Do I also ignore "side to trim" since there is no side trim other than brick surround? c. The "side to side wall" measurement (D) - is that referring to a side wall that is perpendicular to the back wall, or is that referring to the back wall that is to either side of the fireplace/brick? And where does this measurement start - the rear corner of the stove? The center of the stove side? The centerline? Thanks! This site has been very helpful to read.
