We recently moved into a house with a fireplace, but its dimensions are pretty small for an insert. What makes the installation difficult is that the sides of the fireplace do not go straight back, but go diagonal into the back of the hearth. The rear of the heath is appx 17 1/2" wide, and its about the same depth. (Prior stove in old house was a Jotul F3cb) Only insert I have seen out there so far that would fit is the Quadrafire 2700, but from some reviews it seems like this isn't the best stove to get. Setup is that the fireplace is on an exterior wall, and the chimney faces exterior on three sides. (I would be relining the chimney the whole way up vs just 6 feet into the flue) I originally liked the quadrafire as I would not have to build additional hearth protection, but from what I have read online it seems like there aren't a lot of positive comments out there for it. Any suggestions for a small insert would be appreciated. House is a colonial, and the insert wouldbe placed on the 1st floor. 1st floor is 864 square feet, and the room is with the insert is 12 X 36. Thanks for the help/comments!
