ABSTRACT:
A fire-guard is provided for heating a room by convection using the heat from a radiant heat source, such as a fire in a fireplace. The fire-guard includes a plurality of substantially vertically extending pipes. Each of the pipes has an inlet opening located adjacent to its lower end for receiving relatively cool air and an outlet opening located adjacent to its upper end for passing air heated by the fire-guard into the room. The portion of the fire-guard extending from its base to a height above the inlet openings constitutes a threshold for preventing the movement of air between adjacent pipes into the radiation heat source. The two pipes of at least one pair of adjacent pipes are hinged together in such a manner to permit pivoting by one of the two pipes about the longitudinal axis of the other of the two pipes.
