I am having a mason build an outdoor wood burning fireplace for us. He has 18 yrs masonry experience and I have seen slot of his work. I am concerned he doesn't really know the proper sizing for our fireplace. The actual opening is 6' (feet) wide 24" deep and 32" high. How high should the chimney be? The fireplace is rectangular, how should the interior of the chimney be sized? I know it needs to be tapered, but to what extent and how narrow /wide should chimney opening be? Should we do 2 openings up top for such a wide fireplace? What materials should he use to accomplish this chimney taper from such a large opening, an insert, anti fracture concrete?
I know these dimensions are critical to insure we do not have the issues many have written about. Any help is much appreciated!
