TECHNICAL DESCRIPTION

The fire 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 are used. The appliance works as an intermittent operating appliance.
The fire 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 ROSETTA BII is endowed with a pre-adjusted tertiary air for a better
combustion. Inside there is a flat grate. The cookers ROSA and ROSETTA BII can be equipped with a OPTIONAL height-adjustable
grate. The upper position optimizes the PLATE function, the lower one the OVEN use. As an OPTIONAL it is available also a
chromium plated grate for the oven.
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.
Under the oven door there is an food warmer holder, with the related closing door: NEVER introduce flammable objects
or materials (Picture 6
Below the food warmer holder there is an extractable wood drawer, with the related closing door (D).
ACCESSORIES

Rosetta BII - Rosetta Sinistra BII
The heating of the environment is made by irradiation: through the panoramic glass and the external hot surfaces of the cookers,
the heat is radiated into the environment.
The cooker is equipped with controls of primary and secondary air by which it is adjusted the combustion air.
1A - PRIMARY Air Register
With the lower register, the passage of primary air in the lower part of the cooker is regulated through the ash drawer and the grill
in the direction of the fuel. The primary air is necessary for the combustion process. The ash drawer must be emptied regularly, so
that the ash cannot block the primary air intake for combustion. The primary air also keeps the flame alive.
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
This register must be open (i.e. turned completely to the right), in particular for the combustion of wood (see Table).
The register regulation necessary in order to obtain nominal calorific output is the following (see Cap. TECHNICAL DATA):

B - FLUE GAS Control (Picture
(Conversion from the cooker HOTPLATE USE – OVEN USE function to the cooker HEATING function)
On the right of the front of the stove/cooker, between the protection rail and the oven door, is the FLUE GAS control lever,
recognisable as a bronze knob. When the lever is pushed towards the back of the stove/cooker, the combustion gases flow above
the oven directly towards the exhaust stub (cooker function – PLATE USE); when the lever is pulled towards you, the combustion
gases flow all around the oven, so the internal temperature increases evenly (cooker – oven cooking and heating – OVEN USE).
To ignite the flame follow the instructions below (see Cap. IGNITION) :
• Open the FLUE GAS Register (cooker function – PLATE USE) to aid flue gas exhaust. Position the register (any butterfly valve
placed on the flue gas exhaust pipe must also be opened).
• Open the primary air register (placed on the ash tray).
• After having started the fire with small pieces of wood and waited until it is well lit.
• Bring the flue gas register to the oven position.
• Close the 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 completely open.
• Load wood as described in the manual (hourly load).
