A self-contained window unit adapted to be assembled into an oven door window opening and having means defining an air passage to allow air to flow upwardly through the door and window unit therein. The window unit is mounted on the back panel or liner of the door and comprises a window sub-assembly having a pair of glass panes held in spaced parallel relation. A front glass pane is secured to the subassembly by mounting clips. The mounting clip or clips at the top are constructed so as normally to hold the front pane against upward movement but to permit the front pane to be pressed outwardly for upward removal. The spaces between the clips allow upward flow of air through the door and window unit. |
