I just purchased a 2023 Hearthstone IV model 8024 wood stove which replaced an old Hearthstone II that I used since 1985. The mode 8024 has a double grate for ash removal. To remove ash you need to open the ash door and grab a small cast handle and pull to open the bottom grate. Your choice is to either slide the grate back and forth to empty the fire box of ash or push the ash through both grates to the ash bin. The problem is small chips of ash jam up the holes in the two grates that prevent movement of the bottom grate to empty the ash or to even open or close the grate. Hearthstone does not recommend leaving the bottom grate open. The only way to empty the ash is via shovel or stop burning, cool, and then go into the fire box and remove any chips in the grate. Has any one experienced this problem and solved it. In my opinion this arrangement is a very poor design.
