10. ALLOWED / NOT ALLOWED FUELS
10.1. WOOD
Allowed fuels are logs. Use exclusively dry logs (max. content of water 20%). Maximum 2 logs should be loaded. The pieces of wood
should have a length of ca. 20-30 cm and a maximum circumference of 30-35 cm.
Compressed not worked-out wood briquettes must be used carefully to avoid overheating that may damage the device, since
these have a very high calorific value .
The wood used as fuel must have a humidity content lower than the 20% and must be stored in a dry place. Humid wood tends to burn
less easily, since it is necessary a greater quantity of energy to let the existing water evaporate. Moreover, humid content involves
the disadvantage that, when temperature decreases, the water condensates earlier in the hearth and therefore in the stack causing a
remarkable deposit of soot with following possible risk of fire of the same.
Fresh wood contains about 60% of H
2
O, therefore it is not suitable to be burnt.
It is necessary to place this wood in a dry and ventilated place (for example under a roofing) for at least two years before using it.
Besides others, it is not possible to burn: carbon, cuttings, waste of bark and panels, humid wood or wood treated with paints,
plastic materials; in this case, the warranty on the device becomes void.
Paper and cardboard must be used only to light the fire.
The combustion of waste is FORBIDDEN and would even damage the appliance and the flue, causing health damages and claims by
the neighbourhood owing to the bad smell. The wood is not a fuel which allows a continuous operation of the appliance, as consequence
the heating all over the night is not possible.

RESINOUS WOOD NOT SUITABLE FOR THE BURNING
ATTENTION : the continuous and protracted use of aromatic wood (eucalyptus, myrtle etc.) quickly damages the cast iron parts
(cleavage) of the product
.
10.2. CIRCULAR PRESSED WOOD BRIQUETTES
While firewood has a heating power of 4.4 kw/kg (with 15% humidity, therefore after approximately 18 months seasoning), that of pressed
wood briquettes is 4.8 kW/kg.
The wood pressed briquette density is 650 kg/m
3
, and the water content is 8% of its weight. For this reason briquettes do not have to be
seasoned in order to obtain a sufficiently adequate heat yield.
CIRCULAR shaped pressed wood briquettes must have a diameter of 60-70-80-90-100 mm, a maximum length of 340 mm. and comply
with the features described by the existing standards in force.
The use of poor-quality pressed wood briquettes, or any other material, damages the performance of your stove and can lead to the
termination of the warranty, and the attached responsibility of the manufacturer.
BRIQUETTES STORAGE: To guarantee a problem-free combustion, it is necessary to store pressed wood briquettes in a dry place.
11. CIRCULAR PRESSED WOOD BRIQUETTES FEEDING
WARNING: The briquettes tank feeding can be performed with the stove switched on or off. The AUTOMATIC function mode is
provided ONLY with the use of CIRCULAR shaped pressed wood briquettes.
• IT IS FORBIDDEN TO FEED LOGS OF WOOD IN THE TANK - Picture 11 at page 41 .
• ADJUST THE TANK ACCORDING TO THE SIZE OF THE BRIQUETTES USED - Picture 11 at page 41 .
• FEED ONLY CIRCULAR SHAPED AND SAME SIZE PRESSED WOOD BRIQUETTES IN THE TANK - Picture 11 at page 41 .
Pressed wood briquettes must have a diameter of ø 60 - 70 - 80 - 90 - 100 mm, a maximum length of 340 mm, and must comply with the
features described by the existing standards in force.
IMPORTANT
:
The briquettes to be fed must be integral, as linear as possible, and have a surface without protrusions that could
in any way prevent the rotation of the briquette inside the automatic feeding system .
• Open the feeding door located on the left side of the appliance, and pull the upper part of the door outwards ( Picture 11 at page 41 A ).
• Release the briquettes feeding door by rotating lever ( B ).
• Open the loading door, pull spring knob (
C
) and adjust the passage of briquettes according to their diameter by moving lever (
D
).
• Feed the briquettes in the housing.
