Hello all. Thank you for taking the time to read my thread and hopefully help me out. I am driving myself a little crazy with questions before my first wood stove purchase. I am planning to purchase a Woodstock Progress Hybrid. I have a 6 year old house, well insulated, 2300 square feet.... but with a great room that is 32' x 25', tall 19' cathedral ceilings at the peak, and LOTS of windows. Great room opens to a 2nd floor loft bedroom that is 30' x 16'. The house is only 1 bedroom right now with a garage that can be converted easily if the need arises (meaning marriage and family). Right now, I'm single and don't need more space. So, with that large volume of space in the great room/loft bedroom, I figured I would need a decent sized stove. Plus with the possiblity of 900 more square feet of finished space, I want to size correctly. Hence the Progress Hybrid. Seem right?
Now, for the clearancees. I have a true masonry fireplace. It is faced with brick all the way up to the ceiling, and is 6'6" wide at the face. I do know that the brick on the very edges, like 2", overlays drywall and the brick above the firebox is on drywall from about 5'6" and up. So call the true masonry fireplace at 6' wide and 5'6" tall. I will be bringing the liner out of the back of the Progress and up my chimney... about 20'. I plan to insulate the liner as well.
My hearth is too tall and not deep enough. So I'm going to remove the existing brick hearth and replace it with a hearth that will be about 7" tall, with a first row made up of brick laying flat and the top of the hearth made up of brick sitting on the edge. The hearth will be the full width of the fireplace, 6'6" wide, and about 37" deep in order to accomodate the Progress at 25" with the 12" for the front hearth clearance. I may get the ash lip so I can shrink that 4 inches, but that will be a game day call. There is cement cantilvering out from the fireplace foundation to support the hearth. My new extension will be extending out over a plywood subfloor, and will lay directly over a joist. So I'm not worried about support. I know the Progress is heavy, but I am reducing the load of the hearth and will tie the new work into the cantilevered masonry under the existing hearth. And the original mason will be helping me, so I know it will be done well.
So, is that 7" of brick enough? By my reading, that gives me an R-Value of about 1.2. The manual calls for .8. I am assuming that the brick's mortar carries the same R-Value, or is that a different game? There is mortar between each brick. If that carried heat differently and through the hearth, then that would be an issue.
Where I am really driving myself crazy is the clearances around the stove. The Progress will sit in front of the firebox, so I'm not worried about the rear clearance. The stove will have about 2' of hearth on either side of it. My concern is about the wall clearances. The manual calls for 24" of distance from the sides of the stove. Now, I have that in a direct, perpendicular line to the stove. No problem. But am I also supposed to take that from the back corner of the stove? Remember, there are two or three inches of drywall under the very edges of the brick face on either side. I built a cardboard mock-up of the stove, and placed in in position. From the corner, I can get 24" to the very edge of the brick face. Under that, there is a combustible. Am I worrying about that for no reason, or is this a concern?
Any other advice, comments would be greatly appreciated.
Thanks
Josh
