Is it OK to run the stove without the ash tray. I would just as soon remove it and just remove the ashes with a shovel when necessary and use the extra space under the stove for some stove suppliesl As far as I can tell there is no grate feeding directly into the tray and the only way to move the ashes down is to pull a very sticky lever which opens a small sliding piece of metal which right now is covered with a small firebrick--kind of a pain
