- 1 - ABSTRACT A fire-guard is provided for heating a room by convection using the heat from a radiation heat source, e.g. a fire place, and when the heat source is an open fire for preventing sparks or other small particles of combustion from entering the room in which the fireplace is located. The fire-guard includes a plurality of spaced apart substantially vertical pipes, having each at or near their lower end an inlet opening and at or near their upper end an outlet opening for air from the room. The portion of the fire-guard extending from its base to a height beyond the inlet openings constitutes a threshold for air flowing from the room towards the heat source. The pipes of at least one pair of adjacent pipes of the fire-guard are hinged together for pivoting about the longitudinal axis of at least one of the said two pipes.
