Close the lower door, then turn on the main switch 1. Put on the central part of the wood collecting chamber
bottom cement plate, on the cast iron grate, some dry and thin pieces of wood in a crossed pattern. Over the
wood put some easily flammable materials, avoid large and square shaped pieces. Using some thin paper
sheets (such as newspapers), light the wood. Immediately close the upper wood collecting chamber door.
