Air Entrance Into The Installation Place During Combustion; Admitted / Not Admitted Fuel - LA NORDICA MIGNON Instructions Pour L'installation, L'utilisation Et L'entretien

The connection to the chimney must be performed with stable and strong pipes (we recommend a
thickness of 2 mm). The pipe for smokes exhaust must be fixed hermetically to the chimney. The diameter
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's 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. 7).
The depression on the chimney should be 12 Pascal (=1,2 mm of water column). The measurement must
be done always with the equipment hot (rating calorific value). When the depression exceeds 17 PA
(1.7mm 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.
For safety reasons the door of the stove must be opened only for the loading of the fuel or for removing the
ashes, while during the operation and the rest, the door of the hearth must remain closed.

AIR ENTRANCE INTO THE INSTALLATION PLACE DURING COMBUSTION

As the stoves 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
positioned in the nearby of the appliance or through air connection towards outside or a near ventilated
room, with the exception of thermal units place or garages (FORBIDDEN).
The connection pipe must be flat with a minimum diameter of 120 mm, a maximum length of 4 m and with
no more than 3 bends. If there is a direct connection with the outside it must be endowed with a special
windbreak.
The air entrance for combustion into the installation place must not be closed during the operation of the
stove. It is absolutely necessary that in the environment in which the stoves operate with the natural flue of
the chimney, it is introduced as much air as necessary for the combustion, i.e. up to 25 m
The natural recirculation of air must be ensured by some fixed openings on the outside. The size of the
necessary openings for air is fixed by the relevant prescriptions. Ask information to your chimney sweeper.
The openings should be protected with grids and should never be obstructed.
An extraction hood (aspirating) installed in the same room or in a room nearby, causes depression with
output of combusted gasses (smoke, smell). As consequence a contemporary operation of the hoods is not
possible.
The depression in an extraction hood can at worst hypothesis, transforms the flue into an external
air intake, by sucking the smokes of the rooms with dangerous consequences for the people.

ADMITTED / NOT ADMITTED FUEL

The fuel admitted is made of wood logs. One must use only logs of dry wood (water content max. 20 %).
The wood pieces should have a length of 30 cm's and a maximum circumference of 30 cm's.
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 H
Among the others, the following cannot be burnt: remainders of coal, cut-outs, scraps of bark and
panels, humid wood or treated with varnishes, plastic materials; in this case the warranty on the
equipment expires. Paper and carton must be used only for ignition.
The combustion of wastes is forbidden and 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.
