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 is endowed with a pre-adjusted tertiary air for a better combustion. Inside there
is a flat grate. 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.
The cookers can be equipped with a OPTIONAL height-adjustable grate. The upper position optimizes the PLATe function, the lower one the
OVeN use.

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.

1A - PRImARy Air Register (Picture
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.

2A - SECONDARy Air Register
This register must be open (i.e. turned completely to the right), in particular for the combustion of wood, so that unburnt carbon does not
undergo a post-combustion (see chapter NORmAL OPeRATION).
Through this register it is possible to adjust the power of the heating. Leaving it slightly open, according to the flue of the chimney, it is
possible to keep the glass clean.

(Conversion from the cooker PLATe use function to the cooker heATINg – OVeN use 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 :
