A fire-guard device is provided for heating a room by convection using the heat from a conventional radiation heat source. The device includes a plurality of pipes in which all adjacent pairs of pipes are pivotably interconnected together. Each pipe is mounted in its own piece of tubing. Each piece of tubing has hinge eyes joined thereto for use in providing the pivotal connection between pipes. The pieces of tubing and hinge eyes form a threshhold for the relatively cool air flowing to the device over the floor of the room in which the device is located.
