Abstract
A gas fired infrared radiation emitter which contains a back-body provided with a distributor, a primary radiator having a combustion surface, and frame which contains four receptacles, each of which is integrally connected to the frame. A screen is removably attached to the frame receptacles by means of two bars, each of which is disposed within the receptacles and is free to move within the receptacles in either direction for a distance of at least about 0.15 inches. Stop surfaces are provided, however, for limiting the amount of longitudinal movement of the bars within the receptacles. The bars each have a length which does not exceed the length of the frame; and they can readily be removed from the receptacles.
