A self-contained window unit that may be installed in a solid fuel burner or like device. The window unit comprises a safety shield which may consist of a glass pane and/or a safety screen, and a frame surrounding the safety shield. The frame is composed of frame elements fabricated in separate lengths with brackets at the corners of the frame to secure the frame elements together. Preferably there is a cushion element between the safety shield and the frame to minimize the risk of breakage. The unit may be mounted on the fuel burner by hanger brackets on the frame or by threaded studs carried by the brackets.
