center the wrap around cabinet type insulated enclosure 51 has an open base and is shown positioned as a cap over firebox 50 and held in place by spacer posts 57 the base and outer walls 52 with the exhaust chimney connector 56 above fig9 are shown holding firebox 50 with wrap around enclosure 51 attached and with each to be connected to the fireplace front fig1 fig1 shows a cut away view of the free standing fireplace with a wood fire burning and illustrates with arrows the flow pattern of the hot exhaust gases as they exit the firebox area 50 and are guided by the wrap around enclosure 51 to blanket the upper outside of the firebox area thereby causing high temperatures and the burning of existing smoke particles plus improving the combustion efficiency of the burn as the hot exhaust gases pass from under the open base enclosure 51 they are at the bottom of the fireplace and against the inside of the outer cover 52 of the fireplace and as said hot gases rise to the fireplace exhaust chimney 58 all of the outside cover of the free standing fireplace becomes a hot heat exchanger surface thereby giving said fireplace a high efficiency rating for heat extraction at least one door 53 located near the upper part of enclosure 51 can be opened by handle 54 fig1 when needed for draft to serve as a short by pass route for exhaust gases to reach the chimney when a fire is first ignited in the fireplace as the fire.
