Zero clearance is a term used to describe a certain fireplace’s ability to be enclosed completely by combustible building material that can be positioned right up against the body of the fireplace. That is the back, top, bottom and sides. The front area is designed to radiate heat and therefore must be given adequate clearance to combustibles. In this case, objects such as furniture, should be kept a minimum of 48″ away. With the exception of our stoves and inserts, all our other models are designed, tested and approved to be installed with zero clearance to combustible framing.
