installation Feed and vent pipework The feed and vent pipework from the boiler to the F & E (Feed & Expansion) tank should be configured as shown in the fig. below. 500mm Minimum Height 22mm (Min.) Vent Pipe 15mm (Min.) Cold Feed Cylinder Flow 2M Minimum Return Pump Flow Heating Circuit 150mm Max. Return 15mm (Min.
installation Note: • The distance between the cold feed and the open vent pipe shall be no more than 150mm. • The cold feed must be inverted as shown. • The open vent pipe must be a minimum of 22mm diameter. • The cold feed pipe must be a minimum of 15mm diameter. • The cold feed and open vent pipes must rise continuously and be unrestricted. • The minimum distance from the top of the boiler to the bottom of the F & E tank shall be no less than 2m. Whilst the maximum distance shall be not more than 27m.
installation Flushing and Water Treatment 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 8 - 16).
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.
installation Instructions for opening the casing and performing an internal inspection 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 valve. To access the inside of the boiler, the following is necessary: 1. Loosen the two screws on the front casing (a), pull it forwards and unhook it from the upper pins (b) 3. Remove the control panel (c) 4.
installation Before the boiler is used for the first time, the trap must be filled with water. To do this, add approximately 1/4 litre of water via the flue outlet before fitting the flue system, or unscrew the cap on the trap positioned underneath the boiler, fill it with water and refit it Warning! Insufficient water in the trap can temporarily cause the flue gas to be expelled into the surrounding ambient air. Water circuit diagram A B 1 2 8 3 7 4 6 5 C 20 1. 2. 3. 4. 5. 6. 7. 8. C.H.
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 Warning The exhaust gas ducts must not be in contact with or close to inflammable material and must not pass through building structures or walls made of inflammable material. When replacing an old appliance, the flue system must be changed. Important Ensure that the flue is not blocked. Ensure that the flue is supported and assembled in accordance with these instructions.

installation Fitting the Twin Pipe (Ø80 / 80) the previous section of flue pipe or elbow, check that the o-ring is not dislodged when assembling the flue (greasing the seal will aid assembly). Twin pipe can also be converted back to coaxial flue to enable vertical termination with a coaxial kit by using the pipe bridge (Twin - Coaxial Adaptor - Part No. 3318089). When running the twin flue pipe vertically. It is not possible to terminate concentrically horizontally.
installation 180 105 195 120 Fig. 9 Fig. 10 For coaxial systems, the maximum flue lengths, mentioned in the table on page 28 also take into account an elbow. For twin flue systems the maximum flue length, mentioned in the table includes the exhaust gas/air intake terminal. Twin flue outlets should respect the following instructions: 1- Use the same ø 80 mm flue pipes for the air intakes and exhaust gas ducts.

The display shows the value between 100% (“99” on the display) and 0% (“0”).
commissioning Test function and combustion analysis The boiler has two pressure test points 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 test points, unscrew the screw which holds the blanking cover and its seal together. Checking the gas setting To carry out combustion analysis, the test function must be activated.
commissioning AUTO function The AUTO function determines the best power output and flow temperature for the heating system by continually monitoring demand. It uses advanced modulating technology to closely track demand and matches output with the highest precision. This ensures that either with or without the addition of further controls the activation of the AUTO function will enhance boiler performance.
boiler protection devices Boiler protection devices The boiler is protected from malfunctioning by means of internal checks performed by the P.C.B., which stops the boiler from operating if necessary. In the event of the boiler being shut off in this manner, a code appears on the display which refers to the type of shut-off and the reason behind it.
