The Stock Cube is beautifully simple to control, there is one air control knob. This is both the air boost, when fully extended and finer control when eased inwards. It comes with an air control tool to help you judge the boost control, but can equally just be operated by hand. Wood burns better on a bed of ash, but when you do want to empty it, you just scoop it out from the base of the firebox. You can fit a small kettle or saucepan on the top surface. If you regularly use the top plate there is an optional stainless steel top available. This sits on top of the stove and has a U shaped cut out for the flue.
