10.6 Mounting the Appliance After removing the boiler from its packaging, remove the template from the separate box containing the connection kit. NOTE: Pay particular attention to any test water that may spill from the appliance. 44 39 40 41 38 Place the template in the position the appliance is to be mounted and after ensuring it is hanging squarely, use it to drill the holes for the hanging bracket, connection kit and flue pipe(s) NB: For further information relating to the flue installation please refer to Section 11 FLUE CONNECTION. (If the appliance is to be fitted on a wall of combustible material, the wall must be protected by a sheet of fireproof material). If the appliance is to be fitted into a timber framed building, guidance should be sought from the Institute of Gas Engineers document REF: IGE/UP/7. 42 43 Legend: 39 = Gas service tap 40 = Heating return 41 = Heating flow 42 = Water service tap 43 = Tank hot water flow 38 = Water tank valve 44 = Heating valve 10.7 Electrical Connection FIG. 10.2 10.6.1. Drill the wall and plug using those supplied with the connections kit, position the hanging bracket and secure with the wall bolts supplied, assembl the connection kit and secure to the wall. NOTE: It is highly recommended that a spirit level be used to position the appliance to ensure that it is perfectly level. 10.6.2. Position the appliance on the hanging bracket and connect the connection kit to the boiler connections. (see also Sections 10.8 Gas Connections, 10.9 Water Connections & FIG.10.2). For safety purposes, have a competent person carefully check the electrical system in the property, as the manufacturer will not be held liable for damage caused by the failure to earth the appliance properly or by anomalies in the supply of power. Make sure that the residential electrical system is adequate for the maximum power absorbed by the unit, which is indicated on the rating plate. In addition, check that the section of cabling is appropriate for the power absorbed by the boiler. The boiler operates with alternating current, as indicated in the Technical Information table (Section 21), where the maximum absorbed power is also indicated. Make sure that the connections for the neutral and live wires correspond to the indications in the diagram. The appliance electrical connections are situated on the reverse of the control panel (see the Servicing Instructions Section 18 for further information). 16 FIG. 10.3 Important! In the event that the power supply cord must be changed, replace it with one with the same specifications. Make the connections to the terminal board located within the control panel, as follows: - The yellow-green wire should be connected to the terminal marked with the earth symbol; make sure to reuse the ferrule mounted on the other supply cord; - The blue wire should be connected to the terminal marked “N”; - The brown wire should be connected to the terminal marked “L”. Note: The diagrams for the electrical system are indicated in Section 13.
Warning, this appliance must be earthed. External wiring must be correctly earthed, polarised and in accordance with relevant regulations / rules. In GB this is the current I.E.E. WIRING REGULATIONS. In IE reference should be made to the current edition of the ETCI rules. This boiler is supplied for connection to a 220 - 240 V ~ 50 Hz supply. The supply must be fused at 3 A. The method of connection to the electricity supply must facilitate complete electrical isolation of the appliance, by the use of a fused double pole isolator having a contact separation of at least 3 mm in all poles or alternatively, by means of a 3 A fused three pin plug and unswitched shuttered socket outlet both complying with BS 1363. The point of connection to the Electricity supply must be readily accessible and adjacent to the appliance unless the appliance is installed in a bathroom when this must be sited outside the bathroom. 10.8 Gas Connection The local gas region contractor connects the gas meter to the service pipe. The gas installation should be in accordance with the relevant standards. In GB this is BS6891 and in IE this is the current edition of I.S.813. The connection the the appliance is a 22 mm copper tail located at the rear of the gas service cock (Fig. 10.2). If the gas supply for the boiler serves other appliances ensure that an adequate supply is available both to the boiler and the other appliances when they are in use at the same time. Pipe work must be of an adequate size. Pipes of a smaller size than the boiler inlet connection should not be used. 10.9 Water Connections Central Heating Detailed recommendations are given in BS 6798:1987 and BS 5449-1:1990, the following notes are given for general guidance. Pipe Work: Copper tubing to BS EN 1057:1996 is recommended for water pipes. Jointing should be either with capillary soldered or compression fittings. Where possible pipes should have a gradient to ensure air is carried naturally to air release points and water flows naturally to drain taps. The appliance has a built-in automatic air release valve, however it should be ensured as far as possible that the appliance heat exchanger is not a natural collecting point for air. Except where providing useful heat, pipes should be insulated to prevent heat loss and avoid freezing. Particular attention should be paid to pipes passing through ventilated spaces in roofs and under floors. By-pass: The appliance includes an automatic by-pass valve, which protects the main heat exchanger in case of reduced or interrupted water circulation through the heating system, due to the closing of thermostatic valves or cock-type valves within the system. 17
