ADMITTED/NOT ADMITTED FUEL
The fuels admitted are wood logs. One must use only logs of dry wood (water content max. 20 %). The
size of wood logs should be 30 cm's long and 30 cm's max in circumference.
The wood used as fuel must have a moisture contents lower than 20 %, which is obtained after at least 1
year drying (tender wood) or 2 years (hard wood) and must be stored in a dry and ventilated place (for ex.
Under a shed). The wet wood makes ignition more difficult because it is necessary a greater quantity of
energy to evaporate the existing water. The humid contents has the disadvantage that, with the
temperature lowering, the water condensates first in the hearth and then in the chimney. The unseasoned
wood contains about 60 % of H20, then it is not suitable to be burnt. The following cannot be burnt:
rests of coal, cutoffs, parts of barks and panels, wet wood or treated with varnished, plastic
