5660-B Overview
The Morsø 5660 B is a non-catalytic wood burning fireplace insert built around a 4-sided picture-frame face and an oversized viewing window that the brand markets as a 'window of fire.' Maximum heat output is 43,499 BTU/hr and the 5660 B heats areas up to 2,200 sq. ft., making it the largest wood-burning unit in the Morsø lineup and well-suited to large open-plan living rooms or whole-home zone heating from a primary fireplace.
The 5660 B is offered in two factory configurations. The Standard configuration ships without blower compatibility. The Blower configuration includes the housing and wiring for an optional blower (the insert is tested with a Fasco B22508 blower). Both configurations accept the 5660 outside air kit (sold separately) and are mobile home approved. Trim kits are available in 3-sided and 4-sided wide configurations to fit a range of existing masonry openings. The cast iron body uses 98% recycled material and carries the Nordic Swan Eco-label.
