the drawer of ash and the grate in the fuel direction. The primary air is necessary for the combustion process. The ash drawer must be
regularly emptied, so that the ash does not obstruct the primary air entry for the combustion. Through the primary air the fire is also kept
alive. when the knob is completely on the left, the register is closed, when the knob is completely on the right the register is opened.
