27. ystem Guidance The boiler is suitable for sealed systems only The maximum cold water mains pressure for the appliance is 10 bar All fittings and pipework connected to the appliance should be of the same standard If there is a possibility of the incoming mains pressure exceeding 10 bar particularly at night then a suitable pressure limiting valve must be fitted The boiler is designed to provide hot water on demand If there is a requirement for greater demands for example if the property has several bathrooms and cloakrooms a vented or unvented hot water storage system should be used Showers Any shower valves used with the appliance should be of a thermostatic or pressure balanced type Refer to the shower manufacturer for performance guidance and suitability Flushing and Water Treatment The performance of the appliance could be impaired by system debris or the effects of corrosion The system must be flushed thoroughly to remove metal filings solder machining oils and other fluxes and greases before connecting the boiler If it is an existing system an appropriate flushing and descaling agent should be used Refer to BS 7593 1992 for guidance For more information on the use of corrosion inhibitors flushing and descaling agents advice can be sought from the manufacturers of water treatment products such as Betz Dearborn Ltd Foundry Lane Fernox Manufacturing Britannica Works Clavering Essex CB11 4QZ
