cod. 3541G920 - Rev. 00 - 08/2015DHW temperature adjustmentUse the DHW buttons (details 1 and 2 - fig. 1) to adjust the temperature from a min. of40°C to a max. of 55°C.fig. 5Room temperature adjustment (with optional room thermostat)Using the room thermostat, set the temperature required in the rooms. If the room ther-mostat is not installed, the boiler will keep the system at the set system delivery setpointtemperature.Room temperature adjustment (with optional remote timer control)Using the remote timer control, set the required temperature in the rooms. The boiler willadjust the system water according to the required room temperature. For operation withremote timer control, please refer to the relevant instruction manual.ECO/COMFORT selectionThe unit has a function that ensures a high domestic hot water delivery speed and max-imum comfort for the user. When the device is activated (COMFORT mode), the watercontained in the boiler is kept hot, thereby ensuring immediate availability of hot wateron opening the tap, without waiting times. The user can deactivate the device (ECO mode) by pressing the eco/comfort button (detail 7 - fig. 1). In ECO mode the display activates the ECO symbol (detail 12 - fig. 1). To activate the COMFORT mode, press the eco/comfort button (detail 7 - fig. 1) again. Adjustments from Remote Timer Control If the Remote Timer Control (optional) is connected to the boiler, the above ad-justments are managed according to that given in table 1.Table. 1System water pressure adjustmentThe filling pressure with system cold, read on boiler water gauge (detail 17 - fig. 1), mustbe approx. 1.0 bar. If the system pressure falls to values below minimum, the boiler stops and the display shows fault F37. Operate the filling cock detail 1 fig. 6 and bring it to the initial value. Always close the filling cock at the end of the operation.fig. 6 - Filling cock3. INSTALLATION3.1 General InstructionsBOILER INSTALLATION MUST ONLY BE PERFORMED BY QUALIFIED PERSON-NEL, IN ACCORDANCE WITH ALL THE INSTRUCTIONS GIVEN IN THIS TECHNICALMANUAL, THE PROVISIONS OF CURRENT LAW, THE PRESCRIPTIONS OF NA-TIONAL AND LOCAL STANDARDS AND THE RULES OF PROPER WORKMANSHIP.3.2 Place of installationThe combustion circuit is sealed with respect to the place of installation, therefore theunit can be installed in any room. The place of installation must be adequately ventilatedto avoid the creation of dangerous conditions in case of any gas leaks. This safety stand-ard is required by the EEC Directive no. 2009/142 for all gas units, including those withsealed chamber.The unit is designed to operate in a partially protected place in accordance with EN 297pr A6, with minimum temperature of -5°C. It is advisable to install the boiler under a roofslope, inside a balcony or in a protected recess.In any case, the place of installation must be free of dust, flammable materials or objectsor corrosive gases.The boiler is arranged for wall mounting and comes standard with a hooking bracket. Fixthe bracket to the wall according to the measurements given in fig. 17 and hook the boileronto it. Wall fixing must ensure a stable and effective support for the generator. If the unit is enclosed in a cabinet or mounted alongside, a space must be pro-vided for removing the casing and for normal maintenance operations3.3 Plumbing connectionsImportant The safety valve outlet must be connected to a funnel or collection pipe to pre-vent water spurting onto the floor in case of overpressure in the heating circuit.Otherwise, if the discharge valve cuts in and floods the room, the boiler manu-facturer cannot be held liable. Before making the connection, check that the unit is arranged for operation withthe type of fuel available and carefully clean all the system pipes.Carry out the relevant connections according to the diagram in fig. 19 and the symbolson the unit.Note: The unit is equipped with an internal bypass in the heating circuit.Water system characteristicsIn the presence of water harder than 25° Fr (1°F = 10ppm CaCO ), use suitably treatedwater in order to avoid possible scaling in the boiler.Antifreeze system, antifreeze fluids, additives and inhibitorsWhen necessary, antifreeze fluids, additives and inhibitors can be used only if the man-ufacturer of such fluids or additives guarantees that they are suitable and do not causedamage to the exchanger or other components and/or materials of the boiler and system.Do not use generic antifreeze fluids, additives or inhibitors that are not specific for use inheating systems and compatible with the materials of the boiler and system.3.4 Gas connectionThe gas must be connected to the relevant connection (see fig. 19) in conformity with thecurrent standards, using a rigid metal pipe or a continuous surface flexible s/steel tubeand installing a gas cock between the system and boiler. Make sure all the gas connec-tions are tight.3.5 Electrical connectionsImportant The unit must be connected to an efficient earthing system in conformity withcurrent safety regulations. Have the efficiency and suitability of the earthingsystem checked by professionally qualified personnel; the Manufacturer de-clines any liability for damage caused by failure to earth the system.The boiler is prewired and provided with a "Y" type cable (without plug) for con-nection to the electric line. The connections to the power supply must be per-manent and equipped with a double-pole switch with contact opening distanceof at least 3 mm, installing fuses of max. 3A between the boiler and the line.Make sure to respect the polarities (LINE: brown wire / NEUTRAL: blue wire /EARTH: yellow/green wire) in connections to the electric line. The unit's power cable must not be replaced by the user; if damaged, switchthe unit off and have the cable replaced by professionally qualified personnel. If replacing the power cable, only use "HAR H05 VV-F" 3x0.75 mm2 cable with max. ext. diameter of 8 mm.Heating temperature settingAdjustment can be made from the Remote Timer Control menu and the boiler control panel.Hot water temperature adjustmentAdjustment can be made from the Remote Timer Control menu and the boiler control panel.Summer/Winter SwitchoverSummer mode has priority over a possible Remote Timer Control heat-ing demand.Eco/Comfort selectionAdjustment can only be made from the boiler control panel.

cod. 3541G920 - Rev. 00 - 08/2015Room thermostat (optional) IMPORTANT: THE ROOM THERMOSTAT MUST HAVE VOLTAGE-FREECONTACTS. CONNECTING 230 V TO THE ROOM THERMOSTAT TERMI-NALS WILL PERMANENTLY DAMAGE THE ELECTRONIC BOARD.When connecting time controls or a timer, do not take the power supply forthese devices from their breaking contacts Their power supply must be bymeans of direct connection from the mains or with batteries, depending on thekind of device.Accessing the electrical terminal blockThe electrical terminal block can be accessed after removing the casing. The arrange-ment of the terminals for the various connections is also given in the wiring diagram infig. 24.fig. 7 - Accessing the terminal block3.6 Fume ductsImportantThe unit is a "C type" with sealed chamber and forced draught, the air inlet and fume out-let must be connected to one of the following extraction/suction systems. The unit is ap- proved for operation with all the Cny flue configurations given on the dataplate. Some configurations may be expressly limited or not permitted by law, standards or local reg-ulations. Before installation, check and carefully follow the instructions. Also, comply withthe instructions on the positioning of wall and/or roof terminals and the minimum distanc-es from windows, walls, ventilation openings, etc.BafflesBoiler operation requires fitting the baffles supplied with the unit, according to the follow-ing tables.Before inserting the fume outlet pipe, it is therefore necessary to check there is the rightdiaphragm (when it is to be used) and that it is correctly positioned. Boilers are fitted asstandard with the diaphragm with the smallest diameter. To replace the baffle (rif. 1 -fig. 8), proceed as indicated in fig. 8.fig. 8Connection with coaxial pipesfig. 9 - Examples of connection with coaxial pipes ( = Air / = Fumes)Table. 2 - TypologyFor coaxial connection, fit the unit with one of the following starting accessories. For thewall hole dimensions, refer to the figure on the cover. Any horizontal sections of the fumeexhaust must be kept sloping slightly towards the boiler, to prevent possible condensatefrom flowing back towards the outside and causing dripping.fig. 10 - Starting accessory for coaxial ductsTable. 3 - Baffles for coaxial ducts Type Description C1X Wall horizontal exhaust and inlet C3X Roof vertical exhaust and inletCoaxial 60/100 Coaxial 80/125Max. permissible length 6 m 12 mReduction factor 90° bend 1 m 0.5 mReduction factor 45° bend 0.5 m 0.25 mBaffle to use0 ÷ 2 m Ø 45 0 ÷ 6 m Ø 452 ÷ 4 m Ø 50 6 ÷ 12 m no baffle4 ÷ 6 m no baffle
