2. TECHNICAL DESCRIPTION
The chimney stoves of La Nordica are suitable to heat living spaces for some periods or to support an
insufficient centralized heating system. They are ideal for holiday apartments and weekend houses or as
an auxiliary heating system during the whole year. As fuel, it is possible to use wood logs.
The chimney stove is made of sheets of metal in galvanized steel, enameled cast iron and, depending on
the model, thermo radiant ceramics or soapstones.The hearth is internally sheathed with single sheets in
cast iron; the back side is extractable. Thanks to some calibrated holes made over that side, the supply of
pre-heated air inside hearth is guaranteed and having, in this way, a post-combustion which increases the
yield and reduces gas output. Inside it there is a turning and extractable grate.
The hearth is equipped with a panoramic door with ceramic glass (resistant up to 700 °C). This allows a
wonderful view on the burning flames. Furthermore, it is thus avoided the output of sparks and smoke.
The heating of the environment is made:
a) by convection (about 70%): the passage of air through the double sheath of the stove releases heat
in the environment.
b)
by radiation (about 30%): through the panoramic glass and the external hot surfaces of the stove,
the heat is radiated into the environment.
The chimney stove is equipped with registers of primary and
secondary air by which it is adjusted the combustion air.
PRIMARY AIR register
(

- A)
With the register below on the left of the door of the hearth it is
adjusted the passage of air through the drawer of ash and the
grate in the fuel direction. The primary air is necessary for the
combustion process. The ash drawer must be regularly emptied,
so that the ash does not obstruct the primary air entry for the
combustion. Through the primary air the fire is also kept alive.
During wood combustion, the register of primary air must be
opened only for a while, because otherwise the wood burns fast
and the stove may overheat.
The register is open when the lever is completely pulled out. The
register is closed when the lever is introduced.
SECONDARY AIR register
Upper lever
(

Over the hearth door will be found the secondary air register.
This register must be opened (in that case the lever must be
moved to the right), especially for wood combustion, so that unburnt carbon can undergo a post-
combustion. See paragraph 10.
3. RULES FOR INSTALLATION
The stove, assembled and ready for the installation, must be connected with a junction to the existing flue
of the house. The junction must be possibly short, straight, horizontal or positioned a little uphill. The
connections must be tight.
It is obligatory to respect the National and European rules, local regulations concerning building
matter and also fireproofs rules. Please apply to your chimney sweeper for all information.
You should verify the sufficient air entrance for the combustion in the installation place, with particular
attention to windows and doors with tight closing (seal ropes).
It is not allowed the connection of various appliances to the same chimney. The diameter of the opening for
the connection must correspond at least to the diameter of the smokes pipe. The opening should be
equipped with a wall connection for the reception of the exhaust pipe and a rose window.
The small hole for the smoke connection pipe not in use must be covered with the related cap.
