INSTALLATION Installing

INSTALLATION Installing the Boiler Please check that you are familiar with the installation requirement before commencing work (pages 11 - 15). The installation accessories described in the following list are included in the boiler packaging: - Hanging bracket - A paper template (showing the dimensions of the boiler with 5 mm side clearances) - Connection valves (compression) - Screws and washers - Filling loop - Installation, Servicing and User manual Method of positioning the boiler on the wall The paper template can be used to ensure the correct positioning of kitchen cabinets etc. E-COMBI ONE The paper template has to be fixed to the wall and used to locate the position of the hanging bracket and the centre for the flue hole. Drill and plug the wall and secure the hanging bracket using the screws provided ensure the hanging bracket is level. Remove the boiler from its packaging and remove the front casing panel. Place the boiler on the hanging bracket. Note: The appliance must not be fitted on a combustible wall surface. Note: Connections viewed from behind boiler Note. Connections viewed from behind boiler. E-SYSTEM ONE Note: Connections viewed from behind boiler Connecting the boiler to the system - Remove the boiler casing as described on page 14 - Remove the caps and connect the valves to the boiler using the washers provided - 5 x fibre washers for the CH flow and return, cold water inlet, gas and hot water outlet connections Safety Valve Discharge The pressure relief valve pipe is made of copper. It should terminate below the boiler safely outside the premises. Care should be taken that it does not terminate over an entrance or window or where a discharge of heated water could endanger occupants or passers by. WARNING! DO NOT APPLY HEAT TO THE COPPER SAFETY VALVE OUTLET PIPE WHILST IT IS CONNECTED TO THE 3 BAR SAFETY RELIEF VALVE. Fill the central heating and DHW system and bleed air from the system as described in the Commissioning instructions (page 32). The system should be carefully checked for leaks, as frequent refilling could cause premature system corrosion or unnecessary scaling of the heat exchanger. The pipe from the trap should be connected to a drain as described in the relevant regulations. Pay special attention not to bend the condensate silicone drain pipe is such a way as to interrupt the flow. Please only use drain pipe material compatible with condensate products (refer to BS 6798:2009). The condensate flow can reach 2 litres/hour because of the acidity of the condensate products (Ph close to 2), take care before operation. See page 15 for condensate discharge options. 14 /

INSTALLATION Gas connection Make sure, using the labels on the packaging and the data plate on the appliance itself, that the boiler is in the correct country and that the gas category for which the boiler was designed corresponds to one of the categories available in the country where it will be used. The gas supply piping must be created and measured out in compliance with specific legal requirements and in accordance with the maximum power of the boiler. Check that the supplied gas corresponds to the type of gas for which the boiler was designed (see the data plate located on the appliance itself). It is also important to check that the pressure of the gas (methane or LPG) you will be using to feed the boiler is suitable, because if it is insufficient the power may be reduced, causing inconvenience for the user. Water connection The illustration below shows the connections for the water and gas attachments of the boiler. See valves configuration on page 14. Check that the maximum water mains pressure does not exceed 6 bar; if it does, a pressure reducing valve must be installed. For the measuring of the pipes and of the heating bodies in the heating system, the residual head value should be calculated as a function of the requested flow rate, in accordance with the values shown in the circulation pump graph. Instructions for removing the housing and inspecting the appliance. Before carrying out any work on the boiler, switch off the power supply using the external bipolar switch and close the gas tap. To access the inside of the boiler: - unscrew the two screws from the front panel (a), pull the panel forwards and uncouple it from the upper pins (b), - pivot the electronic unit by pulling it forwards (c).
