installation Reference Standards In the United Kingdom, the installation and initial start-up of the boiler must be by a CORGI 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. CORGI. building within the vicinity and consideration must also be given to adjacent boundaries, openable windows should also be taken into consideration when siting the flue.
installation Water Supply The boiler is suitable for sealed systems only. The maximum working pressure for the appliance is 6 bar. All fittings and pipework for the appliance should be of the same standard. If there is a possibility of the incoming mains pressure exceeding 6 bar, particularly at night, then a suitable pressure limiting valve must be fitted. The boiler is designed to provide hot water on demand to multiple outlets within the property.
installation ii) Connecting into the waste system of the building such as a washing maching or sink trap. The connection must be upstream of the washing machine/sink. If the connection is down stream of if the waste trap then an additional trap giving a minimum water seal of 75mm and an air break must be incorporated in the pipe run, as above. 3. External termination of condensate drainage pipe via internal discharge branch (e.g. sink waste - proprietary fitting).
installation Installing the Boiler Please check that you are familiar with the installation requirement before commencing work (pages 7 - 11).
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 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 without extension 118 Level 150 mm Fig.
installation Clamp Screws Seal Fig. 4 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 boilers flue connection, grease the seals then add extensions or elbows as required, secure the adaptor, using the clamp and screws provided.
