GeneralAny method of filling, refilling, topping up or flushingsealed primary hot water circuits from the mains via atemporary hose connection is only allowed if it complieswith Water Bye-law 14, which states:" (1) No closed circuit shall be connected to a supply pipe.(2) Paragraph (1) shall not apply to a temporary connectionprovided that:a. The connection is made through a double check valveassembly or some other no less effective device whichis permanently connected to that circuit;andb. The temporary connection is removed after use. "The method described in this instruction complies withthat Bye-law.2. BS. RequirementsThe installation must comply with the requirements ofBS. 6891:1988 and BS. 5449.3. Flow TemperatureThe installation should be designed to work with flowtemperatures of up to 90° C.4. Working PressureAll components of the system must be suitable for aworking pressure of 3 bar (45 lb/in2 ) and temperature of110°C. Extra care should be taken in making allconnections so that the risk of leakage is minimised.The following components are incorporated within theappliance:a. Circulating pump.b. Safety valve; with a non-adjustable pre-set liftpressure of 3 bar (45lb/in 2 ).c. Pressure gauge; covering a range of 0-6 bar.d. 8-litre expansion vessel; with an initial chargepressure of 1 bar (15 lb/in 2).e. Domestic hot water (DHW) mini expansion vessel.For further details refer to BS.5449:1 and the British GasCorporation publication 'Specifications for DomesticCentral Heating and Hot Water'.GENERALTHERMOSTATIC RADIATOR VALVES (TRV)Caradon Plumbing Limited recommend that heating systemsutilising full thermostatic radiator valve control of temperaturein individual rooms should also be fitted with a roomthermostat controlling the temperature in a space served byradiators not fitted with such a valve as stated in BS. 5449.When thermostatic radiator valves are used, the spaceheating temperature control over a living area having a heatingrequirement of at least 10% of the boiler heat output should beachieved using a room thermostat whilst other rooms areindividually controlled by thermostatic radiator valves.For further information refer to the 'Good Practice Guide 143', apublication of the Energy Efficiency Office, available from theBuilding Research Establishment, Garston, Watford WD27JR. Tel: 01923 664258.ELECTRICAL SUPPLYWARNING. This appliance must be efficiently earthed.Wiring external to the appliance MUST be in accordance withthe current I.E.E. (BS.7671) Wiring Regulations and any localregulations which apply.The point of connection to the mains should be readilyaccessible and adjacent to the boiler, except for bathroominstallations where the point of connection to the mains MUSTbe situated outside of the bathroom.Note.Where a room sealed appliance is installed in a roomcontaining a bath or shower then the appliance and anyelectrical switch or appliance control utilising mains electricityshould be so situated that it cannot be touched by a personusing the bath or shower.
