Hogwildz - Only 8" is required on the front and left side of the stove. I have 12" in front. It is a side loading unit so more hearth is required on the right side of the stove. The 7100 is a nice unit. I just wanted a free standing stove. I have this disease. It is called the wood burning stove install disease....... Kinda my hobby I guess. I love doing home improvement stuff. Never had training to do this, just watched this old house growing up I guess. Must have sunk in. I don't have any plans on any new stove anytime soon. Maybe when I build my log home in the woods somewhere in the year 2090 That will be my next install.
