I had an installer visit my home to look at the possible placement of a St. Croix Element stove. It's small, as is my house (1,400 ft sq.). The installer mentioned that I need to provide 3 feet of clearance between the stove and my upholstered couches to the left and right. That's a lot of dead space and too much to sacrifice in a small room. How much distance do you leave between your stove and any upholstered furniture?
