3.5. SYSTEM CONNECTION AND FILLING
Some examples, purely indicative of the installation, are reported at chapter
, while the connections to the thermoproduct are reported
.
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
.
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) no flammable components (e.g. wall units) must be present above the product.
d) If the stove is installed on a wall made of
flammable material, it is necessary to replace
that part of the wall with a non-flammable
material layer, for instance ceramic, stone, glass or steel etc. The replaced part of wall must be as large as the stove is and, starting
from the floor, protrude around 50 cm at least (
C
) from the top side of the stove.
e) on both sides of the cooker for a height of 20cm from the top plate it
must NOT be put any constructive element or inflammable
thing
(furniture, wood covering, material, etc.)
pos.
B
.
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 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.
Crystal and polished stainless steel facing. Possibility to fit between furniture.
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.
