摘要：A fire-guard is provided for heating a room by convection using the heat from aradiant heat source, such as a fire in a fireplace. The fire- guard includes a plurality ofsubstantially vertically extending pipes. Each of the pipes has an inlet opening locatedadjacent to its lower end for receiving relatively cool air and an outlet opening locatedadjacent to its upper end for passing air heated by the fire- guard into the room. Theportion of the fire-guard extending from its base to a height above the inlet openingsconstitutes a threshold for preventing the movement of air between adjacent pipes intothe radiation heat source. The two pipes of at least one pair of adjacent pipes are hingedtogether in such a manner to permit pivoting by one of the two pipes about thelongitudinal axis of the other of the two pipes.
