installation Reference Standards In the United Kingdom, the installation and initial start-up of the boiler must be by a Gas Safe registered installer in accordance with the installation standards currently in effect, as well as with any and all local health and safety standards i.e. Gas Safe. In the Republic of Ireland the installation and initial start-up of the appliance must be carried out by a Competent Person in accordance with the current edition of I.S.
installation Flushing and Water Treatment Location The boiler is equipped with a stainless steel heat exchanger. The detailed recommendations for water treatment are given in BS 7593:1992 (Treatment of water in domestic hot water central heating systems); the following notes are given for general guidance. If the boiler is installed on an existing system, any unsuitable additives must be removed.
installation Condensate Discharge The condensate discharge hose from the boiler must have a continuous fall of 2.5o and must be inserted by at least 50mm into a suitable acid resistant pipe - e.g. plastic waste or overflow pipe. The condensate discharge pipe must have a minimum diameter of 22mm, must have a continuous fall and preferably be installed and terminated to prevent freezing.
installation Installing the Boiler Please check that you are familiar with the installation requirement before commencing work (pages 7 - 13).
installation Safety Valve Discharge and Condense Outlet Gas connection 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.
installation Instructions for opening the casing and performing an internal inspection To calculate the size of the heating installation, refer to the "Available pressure" graph below. Before performing any work on the boiler, first disconnect it from the electrical power supply using the external bipolar switch; removing the fuse and shutting off the gas cock. To access the inside of the boiler, the following is necessary: 1. Remove the casing by unhooking it from the control panel (a) 2.

installation Connecting the Flue Flue System The provision for satisfactory flue termination must be made as described in BS 5440-1. The appliance must be installed so that the flue terminal is exposed to outdoor air. The terminal must not discharge into another room or space such as an outhouse or lean-to. It is important that the position of the terminal allows a free passage of air across it at all times.
installation (Ø 60 / 100 Horizontal) Contents: 1x Silicone O-Ring (60mm) 1x Elbow (90°) 2x Wall Seals (Internal & External) 1x Flue Pipe including Terminal (1 metre - 60/100) 2x Flue Clamps 4x Screws 2x Seals Fig. 3 118 Fitting the Coaxial Flue Installation without extension Level Once the boiler has been positioned on the wall, fit the rubber flue seal into the internal flue turret (see diagram opposite), insert the elbow into the socket and rotate to the required position.
installation Fitting the 5” Flue (Ø 80 / 125 Horizontal/vertical) Once the boiler has been positioned on the wall, it is necessary to insert the Ø80/125 adaptor (Fig. 5) for both horizontal and vertical flue runs into the boiler flue socket (not supplied with flue kit - Part No 3318095). Push the adaptor onto the boiler’s flue connection, grease the seals then add extensions or elbows as required, secure the adaptor, using the clamp and screws provided.
installation Before proceeding to fit the flue, ensure that the maximum flue length has not been exceeded (see the tables) and that all elbows and bends have been taken into consideration. For each additional 90° elbow 1 metre must be subtracted from the maximum flue length, and for each 45° 0.5 metres must be subtracted from the maximum flue length (the height of the vertical adaptor and a 45° bend can be seen in Fig. 8). Fitting the Twin Pipe (Ø80 / 80) Fig. 8a Fig.
installation The maximum permissible flue length for twin flue is dependent on the type of run used (see table below). Fig. 9 180 120 105 195 For further information relating to flue runs not illustrated, please contact the Technical Department on 0870 241 8180. For coaxial systems, the maximum flue lengths listed in the table below take into account an elbow. For twin flue systems the maximum flue lengths listed in the table below includes the exhaust gas/air intake terminal.

installation WARNING Before performing any work on the boiler, first disconnect it from the electrical power supply using the external bipolar switch and remove the fuse. Electrical connections For increased safety, ask a qualified technician to perform a thorough check of the electrical system. The manufacturer is not responsible for any damage caused by the lack of a suitable earthing system or by the malfunctioning of the electricity mains supply.
installation Room Thermostat / Remote Clock Connection The boiler connections for external controls are 12V DC and so only controls of 12V DC that have voltage free contacts should be used. The boiler connections for external controls are 12V DC and so only controls of 12V DC that have voltage free contacts should be used. To connect a room thermostat, it is necessary to: 1. Open the control panel 2. Loosen the cable clamp using a screwdriver and insert the wires leading from the room thermostat 3.

Make sure that the green/yellow earthing wire is connected to an efficient earthing system; - Use a screwdriver to lift the cap on the automatic air relief valve; - Switch on the boiler (by pressing the ON/OFF button), the green led 3 will illuminate indicating that the boiler is ready to operate. Turn the CH button 5 between min. and max position.
commissioning Test function and combustion analysis The boiler has two pressure taps to measure the combustion gas temperature, the combustive air and the concentrations of O2 and CO2 on the outside of the flue gas header. To access these pressure taps, unscrew the screw which holds the blanking cover and its seal together. 50 Only a 2.5 key must be used Minimum gas flow combustion analysis Checking the gas setting To carry out analyses of combustion, the test function must be activated.
boiler protection devices Boiler protection devices The boiler is protected from malfunctioning by means of internal checks performed by the electronic microprocessor P.C.B., which stops the boiler from operating if necessary. In the event of the boiler being shut off in this manner, the led code shows the type of shut-off and the reason behind it.
maintenance Important Maintenance is an essential part of the safe and efficient operation of the boiler and ensures its durability. It should be performed according to the instructions given in current legislation. Perform combustion analysis regularly in order to check the operating efficiency of the boiler and to make sure the combustion is within the boundaries set by current legislation.
