TermoSovrana DSA22 7094211 – EN3. INSTALLATION REGULATIONSInstallation of the thermo stove and auxiliary equipment in relation to the heating system must comply with all currentStandards and Regulations and to those envisioned by the law.Installation relating to the connections of the system, commissioning and the check of the correct functioning must becarried out in compliance with the regulations in force by authorised professional personnel with the requisitesrequired by the law, being national, regional, provincial or town council present in the country within which theappliance is installed, besides these present instructions.Installation must be carried out by authorised personnel who must provide the buyer with a system declaration ofconformity certificate and will assume full responsibility for final installation and as a consequence the correctfunctioning of the installed product.NORDICA S.p.A. cannot be held responsible for lack of respect for such precautions.Before installation, accurately wash the pipes of the system in order to remove any residuals that could compromisethe correct functioning of the appliance.IMPORTANT:a) In case of water leaking, close the water supply and promptly warn the after sales technical service;b) The system working pressure must periodically be checked.c) If not using the boiler for a long period of time, it is recommended that the after sales technical service iscontacted 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.La Nordica S.p.a. declines all responsibility for damage to things and/or persons caused by the system. Inaddition, it is not responsible for any product modified without authorisation and even less for the use of nonoriginal spare parts.Your local chimneysweep must be informed of the installation of the thermocooker, so that he can check its correctconnection to the flue and the level of efficiency of the flue itself.NO MODIFICATIONS CAN BE CARRIED OUT TO THE APPLIANCE.Before installation, check whether your floor can support the weight of the Thermocooker.WARNING ensure the device is placed perfectly level and that the diameter of the smoke exhaust pipe is thatrequired.Connection of more that one stove to the same chimney is not allowed.It is advisable to have your local chimneysweep check both the connection to the chimney and the sufficient flow of airfor combustion in the place of installation.The diameter of the opening for connection to the chimney must at least correspond to the diameter of the flue gaspipe. 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.The DSA thermo cooker models, can be installed in both an OPEN expansion VESSEL system (see chapter 3.1) anda CLOSED expansion VESSEL system (see chapter 3.2).3.1. OPEN expansion VESSEL systemIt is COMPULSORY that the OPEN expansion VESSEL system is provided with:1. OPEN EXPANSION Tank: which has a capacity of 10% of total water content of thermo-product and of theinstallation. This is installed at the highest point of the system, at least 2 m over the radiator that is at the highestlevel.2. SAFETY PIPE : that connects through the shortest way, without descending or siphoning parts, the delivery ofthermo-product to the upper side of open expansion tank. The minimum diameter of safety pipe is 1”gas.3. LOAD PIPE : which connects the bottom of open expansion tank with the return pipe of installation. Theminimum diameter must be ¾” gas. All those parts must no have for any reason meditate intercept bodies thatcould accidentally exclude them and must be placed in rooms which are protected from frost. On the contrary, ifthey freeze, the boiler body could break or even explode. In case of frost placing it will be right to add a properpercentage of antifreeze liquid to the water of installation in order to delete the whole problem. In no way theremust be water circulation in the open expansion tank between the safety and loading pipe. This would cause thewater oxygenation and the consequent corrosion of thermo-product and installation in a very short time.4. THERMAL DISCHARGE VALVE which is a further positive safety that prevents the boiling even when electricenergy is missing. It is made by a valve cover like a pressure safety valve which differs from it as it opens byreaching a pre-calibrated temperature (normally at 94 – 95°C) and unload hot water from the installation
