inside the connection pipe must correspond to the external diameter of the smokes exhaust small trunk of
the stove. This is ensured by pipes according to DIN 1298.
ATTENTION: Eventual flammable pieces in the area of 20 cm round the connection pipes must be
changed with fireproof and not sensitive to heat materials.
For a good operation of the equipment it is essential that in the installation place it is introduced sufficient
air for combustion (see chapt. 8).
IMPORTANT : The unused flue gas exhaust stub pipe must be covered with its respective cap.
The depression on the chimney should be 17 - 20 Pa (1.7 - 2 mm of water column). The measurement
must be done always with the equipment hot (rating calorific value). When the depression exceeds 20 PA
(2 of water column) it is necessary to reduce the same with the installation of an additional flue adjuster
(butterfly valve) on the exhaust pipe or in the chimney.
7. ADMITTED/NOT ADMITTED FUEL
The fuels allowed are wood logs. Only dry wood logs must be used (containing a max water content of
20%). The logs should have a length of 30 cm and a max. circumference of 15-18 cm.

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, cut-offs, parts of barks and panels, wet wood or treated with varnished, plastic
materials. In this case the guarantee on the appliance lapses. Paper and carton must be used only
for ignition.
The combustion of wastes is forbidden. This may damage the stove and the chimney, 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.
WARNING: The continuous and protracted use of aromatic wood (eucalyptus, myrtle etc.) quickly
damages the cast iron parts (cleavage) of the product.
8. AIR ENTRANCE INTO THE INSTALLATION PLACE DURING COMBUSTION
As the cookers take their combustion air from the installation place, it is essential that a sufficient quantity
of air is introduced in the installation room itself.
In case of tight doors and windows (for example houses built according to the energy saving criteria) it is
possible that the air entrance is not guaranteed, compromising the draught, the welfare and the security of
the people. It is necessary to guarantee a further air entrance through an external air intake, to be
