14. ALLOWED/FORBIDDEN FUEL
The allowed fuel is made of wood logs and dark coal. One must use only logs of dry wood (water
content max. 20 %).One must load at maximum 2 or 3 logs of wood simultaneously. The wood
pieces should have a length of 30-40 cm(11.8”-15.75”) and a maximum circumference of 30-35
cm(11.8”-13.8”).
The wet wood makes ignition more difficult because it requires a greater quantity of energy to
evaporate the existing water. The humid content has the disadvantage that, with the temperature
lowering, the water condensates first in the hearth and then in the chimney.
Among the others, the following cannot be burnt: remainders of coal, scraps of bark and
panels, humid wood or treated with varnishes, plastic materials, materials of organic origin;
in this case the warranty on the equipment expires.
Variety Kg/m3 Kwh/Kg moistness 20%
Beech 750 4.0
Oak 900 4.2
Elm 640 4.1
Poplar 470 4.1
Larch* 660 4.4
Spruce* 450 4.5
Scots pine * 550 4.4
* wood not suitable for burning
Paper and carton must be used only for ignition.
The combustion of wastes is FORBIDDEN and it may damage the stove and the chimney, causing
health damages and spread of bad smell.
The wood is not a fuel which allows a continuous operation of the appliance, as a consequence the
heating all over the night is not possible.
ATTENTION: the continuous and protracted use of aromatic wood (eucalyptus, myrtle etc.)
quickly damages the cast iron parts of the product.
