Technical Description; Flue - LA NORDICA MAMY Manuel Utilisateur

TECHNICAL DESCRIPTION

The cookers of La Nordica are suitable to cook on the grill and on the oven and 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, wood logs is used. The appliance works as an intermittent operating appliance.
The cooker is made of galvanized and enamelled steel sheets and enamelled cast iron (doors, front side, plate ).The hearth is totally
sheathed with single cast iron sheets and it is endowed with a pre-adjusted tertiary air for a better combustion. Inside there is a thick
flat grate. The hearth is equipped with a panoramic door with ceramic glass (resistant up to 700 °C) and outside tempered. This allows
a wonderful view on the burning flames. Furthermore, it is thus avoided the output of sparks and smoke.
Below the oven door there is an extractable wood drawer, with the related closing door.
The heating of the environment is made by irradiation: through the panoramic glass and the external hot surfaces of the stove,
the heat is radiated into the environment.
ACCESSORIES
MAMY - SUPREMA - ITALY
The cooker is equipped with controls of primary and secondary air by which it is adjusted the combustion air.
1A – PRIMARY AIR CONTROL
With the inferior air control, which is on the fire door, it is adjusted the passage of primary air into the low part of the cooker, 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. When the knob is completely on the left, the register is closed, when the knob is completely on the right the register
is opened.
During wood combustion, the register of primary air must be opened only for a while, because otherwise the wood burns too fast
and the cooker may overheat.
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):

C – SMOKES control (Picture
(Conversion of the cooker function to the cooker - bake oven and heating function).
On the central part of the front side, there is the command bar of the smokes register which is an enamelled and marked knob.
When the bar is pushed on the left of the cooker, the combustion gases flow over the oven directly into the small trunk of exhaust
(cooker function - PLATE USE); when on the contrary one pulls the lever on the right, the combustion gases flow all around the oven,
so that the internal temperature is increased in an uniform way (cooker, bakeoven and heating function - OVEN USE).
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 :

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.
