I am looking to move my Avalon Olympic fireplace insert to another fireplace. But the new location has a firebox which is not big enough to hold the vast size of the Olympic. Additionally, the firebox within this fireplace is completely shot, warped and has a hole within it. Has anyone removed the firebox safely and placed the stove within the cavity that remains? (I would install a SS liner and the surrounds panels while the cavity is completely masonry.) The Avalon Olympic is sold as a wood burning stove in addition to being used as an insert. I have looked at how these types of fireboxes are built (Hearform, Vestal Aire) and it seems to me that this could work. My only concern is the tile chimney, but they are not suppose to be supposed by the firebox. Anyone?
