Abstract

Abstract A metal fireplace unit suitable for use in mobile homes or the like is formed in the configuration of an eight-sided space capsule. Heat resistant windows are placed on three of the eight sides so that the fireplace presents an attractive appearance when viewed from almost any angle. An efficient heat circulating system is employed so that a maximum amount of heat is extracted from the fuel.
