| 1.5 Gas Supply The gas installation shall be in accordance with the current issue of BS6891. The supply from the governed meter must be of adequate size to provide a steady inlet working pressure of 20mbar (8in wg) at the boiler. On completion test the gas installation for soundness using the pressure drop method and suitable leak detection fluid, purge in accordance with the above standard. | 1.6 Electrical Supply WARNING. This boiler must be earthed. All system components shall be of an approved type and shall be connected in accordance with the current issue of BS7671 and any applicable local regulations. Connection of the boiler and system controls to the mains supply must be through a common isolator and must be fused 3A, maximum. This method of connection must be by a fused double pole isolating switch, with a minimum contact separation of 3mm on both poles. The switch should be readily accessible and preferably adjacent to the appliance. It should supply the appliance only and be easily identifiable as so doing. Alternatively, an unswitched shuttered socket outlet and 3A fused 3 pin plug, both to the current issue of BS1363 may be used provided that they are not used in a room containing a bath or shower. Wiring to the boiler must be to the current issue of BS6500 Table 16, not less than 0.75mm2 (24/0.20mm). 1.7 Contents of Packaging The boiler is delivered in one pack, refer to Section 4.1 for contents. 1.8 Water System This boiler may be fitted to an open vented or a sealed water system. 1.9 Drain System A drain tap must be provided at the lowest points of the system which will allow the entire system, boiler and hot water cylinder to be drained. Draining taps should be to the current issue of BS2879. Boiler A draining point is fitted at the bottom right hand side of the heat exchanger. Cover the controls to avoid water damage. If required remove the combustion chamber front cover to improve access. 1.10 Safety Valve A safety valve need not be fitted to an open vented system. 1.11 Location This boiler is not suitable for outdoor installation. This boiler may be installed in any room, although particular attention is drawn to the requirements of the current issue of BS7671 with respect to the installation of a boiler in a room containing a bath or shower. Any electrical switch or boiler control utilising mains electricity should be placed so that it cannot be touched by a person using the bath or shower. The electrical provisions of the Building Standards (Scotland) apply to such installations in Scotland. The boiler must be mounted on a flat wall which is sufficiently robust to take its total weight. The boiler may be fitted to a wall made of combustible material. |
