I would like to install a medium to large wood burning appliance in a basement. The ceiling is just higher than 6 feet and is open floor joists. Most appliances are specified for installation under a ceiling that is at least 7 feet. Does anyone know of a heater that is permitted for operation under a 6 feet combustible ceiling? I am 6 feet tall and do not want to be bumping my head on shields or any other ceiling treatment.
