First-Aid Measures; Flue - Nordica AMERICA Instructions Pour L'installation, L'utilisation Et L'entretien

The cooker must operate exclusively with the ash drawer completely closed. The solid residues of the
combustion (ashes) must be collected in a hermetic and resistant to fire container. The cooker must never
be ignited in the presence of gas emissions or steam (e.g. glue for linoleum, gasoline, etc.). Never
deposit/store any flammable materials near the stove.
During the combustion will be spread thermal energy which warms up the surfaces, the door, the fireplace
glass, the handles and knobs, the smoke pipe and the front side of the stove. Please avoid the contact of
these parts without gloves or the relevant tools. Warn children of the danger and keep them away
during the operation of the stove.
The use of a wrong or wet fuel causes the formation of creosote deposits in the flue and will fuel a chimney
fire.

4.1. FIRST-AID MEASURES

Should any fire arise in the stack or in the flue:
•
Close the feeding door and the ash drawer door.
•
Close the registers of combustion air
•
Extinguish the fire using carbon dioxide fire-fighting means (CO
•
Seek immediate intervention of FIRE BRIGADE.
DO NOT EXTINGUISH FIRE USING WATER JETS
When the fire has been extinguished, let the flue check by an expert to find possible cracks and permeable
points.

5. FLUE

Essential requirements for a correct operation of the device:
•
the internal section must be preferably circular;
•
be thermally insulated and water-proof and produced
with materials suitable to resist to heat,
•
combustion products and possible condensates;
•
not be throttled and show a vertical arrangement with
deviations not greater than 45° ;
•
if already used, it must be clean;
•
observe the technical data of the instructions manual;
Should the flues have a square or rectangular section, internal
edges must be rounded with a radius not lower than 20 mm. For
the rectangular section, the maximum ratio between the sides must
be ≤ 1.5.
A too small section causes a decrease of the draught. It is
suggested a minimum height of 4 m.
The following features are forbidden and therefore they endanger
the good operation of the device: asbestos cement, galvanized
steel, rough and porous internal surfaces. Picture 3 gives some
examples of execution.
The minimum section must be 4 dm
for devices whose duct diameter is lower than 200 mm or 6.25
dm (for example 25 x 25 cm) for devices with diameter greater
2
than 200 mm.
The draught created by the flue must be sufficient, but not
excessive. A too big flue section can feature a too big volume to be
20
(for example 20 x 20 cm)
2
dust).

(1) AISI 316 steel flue with double
chamber insulated with material resistant
to 400° C. Efficiency 100% excellent.
(2) Refractory flue with double insulated
chamber and external
lightweight concrete. Efficiency 100%
excellent.
(3) Traditional clay flue square section
with cavities. Efficiency 80% excellent.
(4) Avoid flues with rectangular internal
section whose ratio differs from the
drawing. Efficiency 40% poor.
