Flue - LA NORDICA SUPREMA 4.0 Manuel Utilisateur

2A – sECONDARY AIR CONTROL
On the hearth door there is the secondary air register. This knob must be totally moved to the right in order to open the control, especially
for wood combustion (see paragraph Table). The secondary air, passing between the double glass of the fire door, heats itself starting the
double combustion and keeping at the same time the glass clean (with open register).
B – sMOkEs control (Picture
(Conversion of the cooker function to the cooker, bake oven and heating function).
The smokes control, in the style of a chromed pull push lever, can be found on the top right corner of the front side of the cooker, between
the protection bar and the oven door. This control has two settings:
HOB COOKING: when the bar is pushed to the back of the cooker, the combustion gases flow around the oven and directly into the flue and
up to the chimney. OVEN COOKING: when the control bar is pulled out, the combustion gases flow around the oven, heating it.
The control regulation necessary in order to obtain nominal calorific output is the following (see Cap. TECHNICAL DATA):
SUPREMA 4.0
To ignite the flame follow the instructions below (see Cap. IGNITION) :
• Bring the flue gas control to the cooker position (any butterfly valve placed on the flue gas exhaust pipe must also be opened).
• Open the primary and secondary air control.
• After having started the fire with small pieces of wood and waited until it is well lit.
• Bring the flue gas control to the oven position.
• Close any butterfly valve placed on the flue gas exhaust pipe must also be opened.
The control regulation during the ignition phase is the following :

How to set the machine to BOIL WATER
• Keep the flue gas register on the cooker function – HOTPLATE USE.
• Primary air half OPEN.
• Secondary air 40mm open
• Load wood as described in the manual (hourly load = hourly consumption).
How to set the machine to COOk BIsCUITs
• Keep the flue gas register on the cooker function – OVEN COOKING USE.
• Primary air CLOSED.
• Secondary air 40mm open
• Switch the cooker on with a moderate load of wood until the oven thermometer indicates 180°C.
• Wait for 220-230°C to be reached without additional wood being loaded.
• Load a single piece of wood weighing 600 - 700 g one at a time and wait for it to burn completely before adding another.
• This keeps the oven temperature stable around 220-230°C.
• Place the tray of biscuits in the medium position for 20 minutes.
• Turn the tray halfway through cooking, if necessary.

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;
• all the sections of the flue gas duct must be accessible to inspection;
• inspection openings must be provided for cleaning.
• 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. Picture 1
For a correct installation please respect the sections/lengths of the flue shown in the technical data table. By installations
with different dimensions the flue must be suitably sized in accordance with EN13384-1.
The draught created by your flue must be sufficient but not excessive.
