2.5. SYSTEM CONNECTION AND FILLING

Some examples, purely indicative of the installation, are reported at chapter 13, while the connections to the thermoproduct are reported
at chapter 14.
ATTENTION: The filling of the system must take place exclusively by the natural fall of the water from the open expansion tank
through the feed pipe in order to avoid that a too high water system grid pressure could change or cause the explosion of
boiler body.
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 watertight test of the installation is performed with the pressure of expansion tank open.
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.

3. 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
Picture 2 at page 52-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. (dimensions according to the local regulations). 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
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.

3.1. 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
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.

4. 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 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.
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.
PRIMARY Air Register (lower knob on the furnace door
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
