Abstract
A prefabricated fireplace, largely made of metal, is provided for permanent installation in a house or similar structure. The fireplace is completely self-insulated so that it does not require any special materials of construction for installation and furthermore, combustion air is supplied for secondary combustion to prevent creosote buildup. Additionally, the fireplace does not use room air for combustion and is substantially airtight so that no room heat is lost up the chimney.
