My insert sticks out 6" into the room past the lintle. I'd like to put a humidifier and cook chile, soup etc. on top like I used to when I had a free stander in a different life. I'm contemplating rigging up a metal plate that sits directly on the stove top, wedged between the stove top and the insert shroud. Figure, about 10" across, and long enough to go back between the top and the shroud. Would stick out about 4" further than currently. Any opinions or thoughts?
