INTRODUCTIONRead these instructions carefully to get the bestfrom your appliance.CENTRAL HEATING SYSTEMS:During the first few hours of operation of thecentral heating system, check that all radiatorsare being heated at an even rate.If the top of a radiator is at a lower temperaturethan the bottom then it should be vented byreleasing air through the venting screw at the topof the radiator. Ask your installer to show youhow this is done. Repeated venting will reducethe quantity of water in the system and this mustbe replenished for safe and satisfactoryoperation of the appliance.When excessive venting or water leaks are foundin the system you must <strong>co</strong>ntact a serviceengineer to inspect the installation and rectifyany fault.Only use additives <strong>co</strong>mpatible with the applianceand system. Use of in<strong>co</strong>mpatible additives cancause damage and will invalidate the applianceguarantee.Sealed heating systems:Where the appliance is fitted to a sealed heatingsystem your installer will inform you of theminimum and maximum pressure which must beindicated on the pressure gauge.Regularly check the pressure is maintained and<strong>co</strong>ntact your installer or maintenance engineer ifthere is a noticeable, permanent drop inpressure. If the system loses pressure it shouldbe repressurised and the cause of the lossinvestigated.CONDENSATE:This is a high efficiency appliance using<strong>co</strong>ndensing technology which will under normaloperation produce a regular discharge of<strong>co</strong>ndensate to drain and at times, give out aplume of water vapour from the flue terminal.GENERAL INFORMATIONROOM THERMOSTAT:A room temperature <strong>co</strong>ntroller must be fitted to<strong>co</strong>ntrol the central heating. Refer to instructionssupplied with the thermostat for information onsiting and setting.THERMOSTATIC RADIATOR VALVES:It is re<strong>co</strong>mmended that this type of valve is fittedto all but one of the radiators (or at least those inthe sleeping ac<strong>co</strong>mmodation). The remainingradiator, which must be where the roomthermostat is located, should be un-<strong>co</strong>ntrolledand must be left open.SHOWERS, BIDETS, TAPS/MIXING VALVES:Standard hot and <strong>co</strong>ld taps and mixing valvesmust be suitable for operating at the water mainssupply pressure. Only thermostatically <strong>co</strong>ntrolledshowers are suitable for use with this appliance.Hot and <strong>co</strong>ld mains fed water can be supplieddirectly to an over-rim flushing bidet subject tolocal water <strong>co</strong>mpany requirements.WATER FLOW:With all mains fed systems the flow of waterfrom individual taps will vary with the number ofoutlets operated simultaneously and the <strong>co</strong>ldwater supply pressure to the property. Flowbalancing using 'ball-o-fix' type valves isre<strong>co</strong>mmended to avoid an excessive reduction inflow to individual outlets.The flow of water demanded from both hot and<strong>co</strong>ld service outlets is dependent on the mainswater supply, it may not be possible in someinstallations to operate all outlets simultaneously.MAINS WATER FAILURE:Central heating:The appliance will operate in central heating mode.Hot water will not be available until the watersupply is restored.4GENERAL INFORMATION <strong>GREENSTAR</strong> <strong>HEATSLAVE</strong> <strong>12</strong>/<strong>18</strong> - <strong>18</strong>/<strong>25</strong> - <strong>25</strong>/328 716 106 <strong>25</strong>3c (11.07)

OPERATING THE APPLIANCEPRESSURE GAUGE:The pressure gauge indicates the boiler/heatingsystem water pressure and has two pointers:USING YOURAPPLIANCE102bar34Red (external) pointer is set manually to indicatethe normal system pressure (1 to 1.5 bar forsealed systems, 0 to 0.5 bar for open ventsystems).Grey (internal) pointer shows the actual systempressure (on sealed systems the pressure willrise when the boiler/system heats up from <strong>co</strong>ld).Please check with your installer what type ofsystem you have.Sealed System pressure whenboiler is operating CHOn sealed systems the red pointer should be setto the normal operating pressure (1 to 1.5 bar)and the grey ponter will fluctuate around thispressure depending on whether the system ishot or <strong>co</strong>ld. If a sealed system pressure dropsbelow 1 bar the system should be repressurisedto between 1 and 1.5 bar and the cause of thedrop investigated. If the pressure rises to morethan 2.5 bar please <strong>co</strong>ntact your installer foradvice.Regularly check that the pressure is maintainedand <strong>co</strong>ntact your installer or maintenanceengineer if a permanent significant drop inpressure occurs.On open vent systems the pressure gauge is notused and the grey needle will remain at thebottom of its scale. If the presure rises to morethan 1 bar please <strong>co</strong>ntact your installer foradvice.10OPERATING THE APPLIANCE <strong>GREENSTAR</strong> <strong>HEATSLAVE</strong> <strong>12</strong>/<strong>18</strong> - <strong>18</strong>/<strong>25</strong> - <strong>25</strong>/328 716 106 <strong>25</strong>3c (11.07)


OPERATING THE APPLIANCEFILLING LOOP: Sealed systems onlyA filling loop is a set of manually operated valvesand a flexible pipe that allow water to be addedto the system when the valves are opened. Thisdevice must be WRAS approved. To <strong>co</strong>mply withlocal water authority by-laws the flexible pipeshould only be <strong>co</strong>nnected when topping up thesystem and dis<strong>co</strong>nnected when not in use.Should the sealed system pressure within yoursystem have dropped to below 0.5 bar (shownon the pressure gauge) you will need to increasethis to ensure your boiler <strong>co</strong>ntinues to runwithout problems.Your installer should have informed you whereto find the filling system and instructed you inits use.USING YOURAPPLIANCEShould this have been overlooked you canincrease the pressure by following theseinstructions:1. The boilers integral pressure gauge should bevisible from the filling link.2. Connect the flexible hose across the twovalves, one leading from the boiler and the otherfrom the mains supply. The <strong>co</strong>nnecting nuts needonly to be hand tight.3. Slowly open both valves ensuring that waterdoes not leak from either end of the flexiblehose.4. You will start to hear water passing across thehose and valves and the grey needle on thepressure guage will rise.5. When the needle rises between 1 and 1.5 barclose both valves, the needle should now remainfixed.<strong>GREENSTAR</strong> <strong>HEATSLAVE</strong> <strong>12</strong>/<strong>18</strong> - <strong>18</strong>/<strong>25</strong> - <strong>25</strong>/328 716 106 <strong>25</strong>3c (11.07)6. The hose should then be dis<strong>co</strong>nnected fromat least one valve, a small amount of water willemit from the hose, this is normal. If water<strong>co</strong>ntinues to issue from the hose the valve hasnot been fully closed or is passing. If it ispassing you will need to <strong>co</strong>ntact your installer toresolve the problem.OPERATING THE APPLIANCE11

TIPS ON ENERGY SAVINGHeating e<strong>co</strong>nomically:The boiler is designed to provide a high level of<strong>co</strong>mfort while keeping oil <strong>co</strong>nsumption and theresulting environmental effect as low as possible.The central heating <strong>co</strong>ntrol on the boiler shouldbe set as low as possible while still maintaining a<strong>co</strong>mfortable room temperature.ENERGYSAVINGThe temperature of each room can be setindividually using the thermostatic radiator valves(except the primary room with the roomthermostat).Roof insulation:Around 30% of the heat loss from a property isthrough the roof. Replace any old insulation withnew insulation, preferably to a minimumthickness of 200mm.Window frames:Single glazed windows, particularly those withsteel frames, can lose a great deal of heat.Consideration should be given to replacementwith PVCu or wooden framed double glazedunits.Curtains:Lined curtains, or heavier full length curtains canprovide excellent insulation. However, alwaysensure that the curtains do not drape overradiators.Draughts:Try to ensure that draughts around doors,windows, letterboxes and keyholes etc., arereduced by using a suitable draught excluder.Warning: do not block or seal any air ventsthat are installed to ensure the centralheating boiler (or other appliance) operatesafely.14TIPS ON ENERGY SAVING <strong>GREENSTAR</strong> <strong>HEATSLAVE</strong> <strong>12</strong>/<strong>18</strong> - <strong>18</strong>/<strong>25</strong> - <strong>25</strong>/328 716 106 <strong>25</strong>3c (11.07)


TIPS ON ENERGY SAVINGRoom thermostats:Reducing the setting of the room thermostat by1°C can reduce fuel <strong>co</strong>nsumption by up to 10%.New <strong>co</strong>ntrol systems:Upgrade your heating <strong>co</strong>ntrol system with thelatest equipment available. The minimum level of<strong>co</strong>ntrol for a heating system is a programmer,interlocking room thermostat and thermostaticradiator valves.Radiators:More often than not radiators will be sitedunderneath a window, so the warm air from theradiator heats the <strong>co</strong>lder in<strong>co</strong>ming air from thewindow.ENERGYSAVINGThe performance of the radiator will be affectedif the curtains are allowed to drape over theradiator or shelves are fitted above it.The positioning of furniture and tables in front ofthe radiator should also be avoided.It is advisable to manually adjust all radiatorvalves every 2-3 months to prevent them fromsticking. It is also important that the plastic topsof all valves are always in position and notcracked or damaged to help prevent accidents.Care should be taken when vacuum cleaningcarpets to avoid damage to valves and pipework.The heating system and the outputs of theradiators have been carefully selected by yourinstaller. The temperature obtainable in any givenroom is dependent on all radiators beingoperated at the same time. If you decide to turnoff radiators in unused rooms, spare bedroomsetc., you may experience slightly lower roomtemperatures in rooms adjacent to unheatedrooms.<strong>GREENSTAR</strong> <strong>HEATSLAVE</strong> <strong>12</strong>/<strong>18</strong> - <strong>18</strong>/<strong>25</strong> - <strong>25</strong>/328 716 106 <strong>25</strong>3c (11.07)TIPS ON ENERGY SAVING15
