Phil M DescriptionThe Focus 3600B’s versatile size, large viewing space, 1.7gr/h emissions and high efficiency make it ideal for retrofits and new installations alike. Power and performance in a small package. At 2.04 cubic feet, the firebox of the Focus 3600B is the same size as the average wood stove, except it takes up less floor space and has a contemporary, built-in design. Despite its compact size, it offers a large viewing space and generates an impressive amount of heat. With such a small footprint, the Focus not only saves space in the home, but it can be installed virtually anywhere. This fireplace is certified for use with 6″ ICC Model EXCEL chimney only.
