Description; Flue - LA NORDICA TERMOROSSELLA PLUS DSA Manuel Utilisateur

DESCRIPTION

Definition: thermo-product according to EN 13240.
La Nordica thermoheating products are ideal for holiday flats and weekend houses or as auxiliary heating all year round.
Wooden logs are used as fuel. The appliance works as an intermittent operating appliance.
The appliance is composed of painted and galvanised sheet steel and cast iron. The fireplace is found inside the boiler, is built in 4
mm thick steel and is reinforced using welded nails. A swivelling, removable grid is found inside the fireplace. The water in the heating
system circulates in the boiler, which absorbs the heat produced in the fireplace.
The ceramic glass window (resistant up to 700°C) of the door provides a lovely view of the burning flames and prevents sparks and
smoke from getting out.
ACCESSORIES
Room heating takes place:
a) by radiation: the heat is radiated into the environment through the panoramic window and the hot external surfaces of the
thermo-product;
b) by conduction: radiators or heat convectors of the centralised system fed by hot water produced by the boiler (See chapter
CALCULATION OF THE THERMAL POWER).
The device is equipped with registers of primary and secondary air.
1A- PRIMARY air register
With the primary air control is adjusted the passage of air through the ash drawer 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. Through the primary air the fire is also kept alive.
During wood combustion, the primary air register must be almost completely closed during wood combustion, as otherwise the
wood burns too quickly and the thermo-product may overheat.
2A - SECONDARY air register
Over the door of the hearth there is the secondary air control.This regulator must be open (the lever must be moved to the right),
especially for wood combustion, so that un-burnt carbon does not undergo a post-combustion. Through this register it is possible
to adjust the power of the stove. Leaving it slightly open, according to the flue of the chimney, it is possible to keep the glass clean.
For a better comfort and corresponding oxygenation of environment, the air can be directly withdrawn at the outside. In order to
do that, the stove can be connected to the external air socket by an junction Ø 120 mm (see Chap. AIR FLOW IN THE PLACE
OF INSTALLATION).
The adjustment of the registers necessary to reach the rated calorific yield is the following one:

FLUE

Essential requirements for correct appliance operation:
• the internal section must preferably be circular;
• the appliance must be thermally insulated and impermeable and built with suitable materials which are resistant to
heat, combustion products and any condensation;
• there must be no narrowing and vertical passages with deviations must not be greater than 45°;
• if already used, it must be clean;
• the technical data from the instruction manual must be respected;
If the flues are of a square or rectangular section, the internal edges must be rounded with a radius of not less than 20 mm.
For the rectangular section, the maximum ratio between the sides must be ≤ 1.5.
A section which is too small causes a reduction in draught. A minimum height of 4 m is advisable.
The following materials are FORBIDDEN and compromise the good operation of the appliance: asbestos cement, galvanised steel,
rough and porous internal surfaces.
The minimum section must be 4 dm
or 6.25 dm (for example 25x25 cm) for appliances with a diameter of more than 200 mm.
