and to those envisioned by the law.
The installation and the relating to the connections of the system, the commissioning and the check of the correct functioning must
be carried out in compliance with the regulations in force by authorised professional personnel with the requisites required by the law,
being national, regional, provincial or town council present in the country within which the appliance is installed, besides these present
instructions.
Installation must be carried out by authorised personnel who must provide the buyer with a system declaration of conformity and will
assume full responsibility for final installation and as a consequence the correct functioning of the installed product.
Before installing the appliance, carry out the following checks:
• Make sure that the floor can support the weight of the appliance, and if it is made of flammable material, provide suitable insulation
(
DIMENSIONS ACCORDING TO REGIONAL REGULATIONS
).
With a flammable floor the appliance must be installed on a 12
cm thick stone or concrete slab
.
• Make sure that there is adequate ventilation in the room where the appliance is to be installed, with particular attention to windows
and doors with tight closing (seal ropes).
• Do not install the appliance in rooms containing collective ventilation ducts, hoods with or without extractor, type B gas appliances,
heat pumps, or other appliances that, operating at the same time, can put the room in depression (ref.
UNI
10683
standard
)
• Make sure that the flue and the pipes to which the appliance will be connected are suitable for its operation.
It is not allowed the
connection of various appliances to the same chimney
.
• The diameter of the opening for connection to the chimney must at least correspond to the diameter of the flue gas pipe. The opening
must be equipped with a wall connection for the insertion of the exhaust pipe and a rosette.
• The unused flue gas exhaust stub pipe must be covered with its respective cap (see chapter DIMENSIONS).
• The installation must be appropriate and has to allow the cleaning and maintenance of the product and the flue.
Before installation, accurately wash the pipes of the system in order to remove any residuals that could compromise the correct functioning
of the appliance.
IMPORTANT
:
a) It would be appropriate to install an automatic or manual air valve to allow the air outlet from the plumbing system;
b) In case of water leaking, close the water supply and promptly warn the after sales technical service;
c) The system working pressure must periodically be checked.
d) If not using the boiler for a long period of time, it is recommended that the after sales technical service is contacted to carry out at least
the following operations: - close the water taps of both the thermal system and the domestic hot water system; - The system must be
kept constantly full of water even during the periods when the use of the thermo-heating stove is not requested. During the winter,
inactivity must be faced with the addition of antifreeze.
The TERMOROSA READY
DSA
thermo appliances, can be installed in a CLOSED expansion Tank system (see chapter
La NORDICA S.p.A. declines all responsibility for damage to things and/or persons caused by the system. In addition, it is not
responsible for any product modified without authorisation and even less for the use of non original spare parts.
Your regular local chimney sweep must be informed about the installation of the appliance so that he can check the correct connection to
the chimney.
3.1. CLOSED expansion Tank system
The TERMOROSA READY
DSA
thermo appliance is equipped with:
1. A 3 bar SAFETY VALVE
: maximum operation pressure allowed for the system is 3 bar (equal to 30 m of the water column). Higher
pressures can cause deformation and breakage of the boiler body.
ATTENTION
: The inside diameter of the supply pipe which
connects the thermoproduct with the security valve must be equal to the internal diameter of the supply junction present in the
thermoproduct. The above mentioned connection pipe must be without siphoning parts.
2. AUTOMATIC THERMAL DISCHARGE VALVE DSA
or
TEMPERATURE SAFETY RELIEF VALVE
, with double safety sensor
3. CLOSED EXPANSION Tank
can be installed on the thermo product return pipe.
ATTENTION
: The inside diameter of the return pipe
which connects the thermoproduct with the closed expansion vessel must be equal to the internal diameter of the return junction
present in the thermoproduct. The above mentioned connection pipe must be without siphoning parts.
4. PUMP CONTROL THERMOSTAT
5. NOISE ALARM ACTIVATION THERMOSTAT
6. NOISE ALARM
7. TEMPERATURE INDICATOR
8. PRESSURE INDICATOR
9. PUMP SYSTEM
IT IS MANDATORY
that the thermo products for domestic heating inserted in
CLOSED Tank
heating systems, must be internally equipped,
with a cooling circuit, prepared by the unit manufacturer, which is activated by a thermal
safety valve
(see chapter
) which does not
require auxiliary power and can guarantee that the standard set temperature limit is not exceeded. Connection between the power supply
unit and the valve must be free from interceptions. Cooling circuit upstream pressure must be at least 1,5 bar.
3.2. AUTOMATIC THERMAL DISCHARGE VALVE DSA
Solid fuel thermo products must be installed with safety devices determined by laws in vigour. For this purpose the product is already
equipped with a heat discharge coil inside the exchanger, as well with an automatic thermal discharge valve
DSA
. The valve works thanks
to the water coming from the same intake of the system: for this reason the filling of the system must remain open all the time with no
interference of any other device in between. You can find the connections at
, Chap. DIMENSIONS position
A
. When the safety
temperature is reached, the automatic thermal discharge valve DSA, the bulb of which is to be connected to attachment
B
, enables the
intake of cold water in the boiler coil, discharging the excess heat out of pipe
C
towards a conveniently installed drain. Cooling circuit
upstream pressure must be at least 1,5 bar.
3.3. SYSTEM CONNECTION AND FILLING
Some examples, purely indicative of the installation, are reported at chapter INSTALLATION LAY-OUT, while the connections to the
