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.
• 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.
• Always leave the recommended air pocket between the appliance and the walls, rear and side min. see Chap. FIRE-FIGHTING
SAFETY MEASURES.
• Establish the type of ventilation (natural or forced) see chapter VENTILATION HOOD OR ADJACENT LOCAL.
• By means of the adjustable feet and using a level make sure that the device is perfectly levelled to allow a correct sliding of the door.
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;
• empty the thermal system and the domestic hot water system if there is risk of freezing.
• The unused flue gas exhaust stub pipe must be covered with its respective cap (see chapter 18 Pos.4).
The DSA thermo appliances, can be installed in both an OPEN expansion Tank system (see chapter 2.1) and a CLOSED expansion Tank
system (see chapter 2.2).
After testing the proper working of the appliance, some days from the installation, it is possible to proceed with the construction
of its aesthetic covering.
WARNING: During the surround building operations it must kept in mind possible and subsequent electrical installed parts maintenance
(Fans, temperature probe, etc) and with hydraulic systems all parts connected to the product.
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.
2.1.
OPEN expansion Tank system
It is COMPULSORY that the OPEN expansion Tank system is provided with:
1.
OPEN EXPANSION Tank: which has a capacity of 10% of total water content of thermo-product and of the installation. This is
installed at the highest point of the system, at least 2 m over the radiator that is at the highest level.
2.
SAFETY PIPE : that connects through the shortest way, without descending or siphoning parts, the delivery of thermoproduct to the
upper side of open expansion tank. ATTENTION: The inside diameter of the supply pipe which connects the thermoproduct with
the open expansion vessel 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.
3.
LOAD PIPE : which connects the bottom of open expansion tank with the return pipe of installation. The minimum diameter must
