INSTALLATION REGULATIONS

Installation of the product and auxiliary equipment in relation to the heating system must comply with all current Standards and Regulations

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 nal installation and as a consequence the correct functioning of the installed product.

Before installing the appliance, carry out the following checks:

• Verify if your structure can support the weight of the appliance. In case of insufcient carrying capacity it is necessary to

adopt appropriate measures, La NORDICA responsibility is limited to the supply of the appliance (See chapter TECHNICAL

DESCRIPTION).

• Make sure that the oor can support the weight of the appliance, and if it is made of ammable material, provide suitable

insulation (DIMENSIONS ACCORDING TO REGIONAL REGULATIONS).

• 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 ue 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 ue gas pipe. The opening

must be equipped with a wall connection for the insertion of the exhaust pipe and a rosette.

• The unused ue gas exhaust stub pipe must be covered with its respective cap (see chapter DIMENISIONS).

• The installation must be appropriate and has to allow the cleaning and maintenance of the product and the ue.

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 DSA thermo appliances, can be installed in both an OPEN expansion Tank system and a CLOSED expansion Tank system .

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 modied 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.

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 thermo-product 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 be ¾” gas.

All those parts must no have for any reason meditate intercept bodies that could accidentally exclude them and must be placed in rooms

which are protected from frost. On the contrary, if they freeze, the boiler body could break or even explode. In case of frost placing it will

be right to add a proper percentage of antifreeze liquid to the water of installation in order to delete the whole problem. In no way there

must be water circulation in the open expansion tank between the safety and loading pipe. This would cause the water oxygenation and

the consequent corrosion of thermo-product and installation in a very short time.

4. AUTOMATIC THERMAL DISCHARGE VALVE DSA which is a further positive safety that prevents the boiling even when electric energy is

missing. It is made by a valve cover like a pressure safety valve which diers from it as it opens by reaching a pre-calibrated temperature

(normally at 94 – 95°C) and unload hot water from the installation delivery. This will be replaced with as much cold water coming from the

open expansion tank loading pipe of open tank by draining away the excessive heat.

5. SAFETY VALVE FROM 1,5 bar: maximum operation pressure allowed for the system is 1,5 bar (equal to 15 m of the water column). Higher

pressures can cause deformation and breakage of the boiler body.

6. SAFETY DEVICES envisioned by Regulations in vigour.

7. CIRCULATION PUMP : . It would be better to install it on the return in order to avoid that it could disconnect itself at very high water

temperatures but checking that it does not drive water in the open expansion tank otherwise it should cause a continuous water oxygenation

with consequent, fast corrosion of boiler body. It must be not to avoid a forced circulation in the open expansion tank. Furthermore it must

be electrically connected to a thermostat or a electronic control unit that can be purchased with the thermo-replace as OPTIONAL part.
