If sawdust or small – crumbled pellets are put into the funnel-shaped part of the stove i.e. the fuel tank, these may
block the pellet (fuel) feeding. Such pellets may cause the electric motor driving the pellet feeding mechanism to
burn out, or they may lead to damages to the electric motor reducer. If you see any such small, crumbled pellets at
the bottom of the pellet tank or at the bottom of the screw conveyor when the tank is empty, vacuum them with a
vacuum cleaner by inserting the vacuum cleaner hose through the openings of the pellet grate.
