thermoproduct are reported at chapter DIMENSIONS .
ATTENTION: The filling of the system has to be filled only by means of the tap (pos.
3). When the manometer (M) shows a
pressure of 1-1,2 bar, close the tap.
During this phase, open all the bleed valves of the radiators to prevent the formation of air sacks, checking the outlet of water to avoid
unpleasant floodings.
The installation must always be full of water even when the thermo-product is not used. During winter season the non use has
to be faced by adding antifreeze substances
.
4. FIRE SAFETY
When installing the product, the following safety measures must be observed:
a) In order to ensure sufficient thermal insulation, respect the minimum safety distance from objects or furnishing components flammable
and sensitive to heat (furniture, wood sheathings, fabrics. etc.) and from materials with flammable structure (see
-
A
).
All the minimum safety distances are shown on the product data plate and lower values must not be used
.
b) In front of the furnace door, in the radiation area there must be no flammable or heat-sensitive objects or material at a distance of less
than
100 cm
. This distance can be reduced to 40 cm where a rear-ventilated, heat-resistant protection device is installed in front of the
whole component to protect.
c) If the product is installed on a non totally refractory floor, one must foresee a fireproof background.
The floors made of inflammable
material
, such as moquette, parquet or cork etc.,
must be replaced
by a layer of no-inflammable material, for instance ceramic, stone,
glass or steel etc. (size according to regional law).
In case the replacement of the floor is not possible, the appliance shall be
placed on a minimum 12 cm thick slab made of stone or concrete
. The base must extend at least
50 cm
at the front and at least
30 cm
at the sides, in addition to the opening of the loading door (see
B
).
d) No flammable components (e.g. wall units) must be present above the product.
The Product must always operate exclusively with the ash drawer inserted. The solid combustion residues (ash) must be collected in a
sealed, fire resistant container. The Product must never be on in the presence of gaseous emissions or vapours (for example glue for
linoleum, petrol etc.). Never deposit flammable materials near the Product.
During combustion, thermal energy is released which leads to considerable heating of the surfaces, doors, handles, controls, glass parts,
the flue gas pipe and possibly the front part of the appliance.
Avoid contact with these elements unless using suitable protective
clothing or accessories
(heat resistant gloves, control devices).
Ensure children are aware of these dangers and keep them away from the furnace when it is on.
When using the wrong fuel or one which is too damp, due to deposits present in the flue, a flue fire is possible.
4.1. IN A EMERGENCY
If there is a fire in the flue connection :
a) Close the loading door and the ash drawer door
b) Close the comburent air registers
c) Use carbon dioxide ( CO
2
powder ) extinguishers to put out the fire
d) Request the immediate intervention of the Fire Brigade
DO NOT PUT OUT THE FIRE WITH WATER.
When the flue stops burning, have it checked by a specialist to identify any cracks or permeable points.
5. TECHNICAL DESCRIPTION
La NORDICA thermocookers are suitable for heating living spaces equipped with a central heating system made up of radiators or
convectors completely or partially replacing the traditional gas or diesel boiler. These 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 thermocooker is composed of galvanised steel sheet plates, enamelled cast iron and thermoradiant ceramic. The furnace is found
inside the boiler made with 4 mm thick steel and reinforced with welded nails. The water from the heating system, which absorbs the heat
produced in the furnace, circulates in the boiler. Inside the furnace, there is a height-adjustable flat grill (
).
As an
OPTIONAL
a grill is also available for the OVEN.
The furnace is equipped with a panoramic door with ceramic glass (resistant up to 700°C). This allows a fascinating view of the burning
flames. In addition, in this way there is no possibility of sparks or smoke escaping.
The heating of the room takes place:
a)
by means of radiation
: through the panoramic glass and the hot external surfaces of the stove, heat is radiated into the room.
b)
by conduction
: through radiators or convectors in the central heating system fed by the hot water produced by the Thermocooker
itself.
The thermocooker is supplied with registers for primary and secondary air and a thermostat with which the combustion air is regulated.
1A - PRIMARY Air Register
(lower knob on the furnace door
A
).
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
(upper knob on the furnace door
pos.
B
).
This register must be open (i.e. turned completely to the right), in particular for the combustion of wood (see Table). The secondary air,
triggers the dual combustion, keeping the glass clean at the same time (register open).
