ABSTRACT:
A fireplace and chimney assembly is provided which includes a two wall chimney construction and a termination shield for reducing the amount of cold air which can radiate into a living area. The termination shield encompasses the base of the chimney construction while providing sufficient open area for cooling air to be drawn into the annular space within the two wall chimney construction. A false ceiling is installed above the shield. A firestop is provided therein for receiving the top end of the shield. The assembly prevents cold air from dropping into the chase cavity around the fireplace when the fireplace is not in use.
