The fusing should be 3 A.Connection must be made in a way that allows <strong>co</strong>mpleteisolation of the electrical supply, such as a double pole switch,having a 3 mm (1/8”) <strong>co</strong>ntact separation in both poles, or aplug and socket serving only the boiler and system <strong>co</strong>ntrols.The means of isolation must be accessible to the user afterinstallation.IMPORTANT NOTESF This appliance must not be operated without the casing<strong>co</strong>rrectly fitted and forming an adequate seal.F If the boiler is installed in a <strong>co</strong>mpartment then the<strong>co</strong>mpartment MUST NOT be used for storage purposes.F Under no circumstances should any of the sealed<strong>co</strong>mponents on this appliance be used in<strong>co</strong>rrectly ortampered with.F If it is known or suspected that a fault exist on the boilerthen it MUST NOT BE USED until the fault has been<strong>co</strong>rrected by a CORGI registered installer or in IE a<strong>co</strong>mpetent person.MINIMUM CLEARANCESClearances of 200 mm (7 7/8“) above and below, 25 mm (1“)at left, 50 mm (2“) at right and 450 mm (17 3/4“) at the front ofABCDEFGAppliance operation lightsDomestic hot water temperature <strong>co</strong>ntrolMain switch and radiator temperature <strong>co</strong>ntrolBoiler reset buttonLock---out signal lampProgrammer (optional)System pressure and temperature gaugeTO LIGHT THE BOILER1 Check that the valves located in the lower part of the boilerare open.2 Switch the electricity supply on.The appliance operation light A will flash every 4 se<strong>co</strong>nds(stand---by <strong>co</strong>ndition).3 If the boiler is to be used for CH and DHW position themain switch as in the following illustration.The appliance operation light A will flash every 2 se<strong>co</strong>nds(operating boiler).ADIAGNOSTIC LIGHTSThe following table gives a summary of the relationshipbetween each of the possible light <strong>co</strong>mbinations and theirmeaning during normal operaion of the boilerCAll CORGI registered installers carry a CORGI ID card, and have a registration number. Both should be re<strong>co</strong>rded in the BenchmarkCommissioning Checklist. You can check your installer by calling CORGI direct on 01256 372300.Caradon Ideal Limited is a member of the Benchmark initiative and fully supports theaims of the programme. Benchmark has been introduced to improve the standards ofinstallation and <strong>co</strong>mmissioning of central heating systems in the UK and to en<strong>co</strong>uragethe regular servicing of all central heating systems to ensure safety and efficiency.THE BENCHMARK SERVICE INTERVAL RECORD MUST BE COMPLETED AFTER EACH SERVICE

In this way, the automatic <strong>co</strong>ntrol facilities willbe fully exploited.Moreover, where the amount of limescale present in the watermay be particularly great, not exceeding the position asshown in the following illustration (about 50 ûC) minimisesannoying incidences of scale deposits and clogging.In these cases, however, it is advisable to install a small watertreatment device. With such a device you should avoidperiodic descaling.Consequently, the DHW heat exchanger will keep itsperformance <strong>co</strong>nsistent for a longer period of time withresulting gas savings.TO SHUT DOWN THE BOILERFor short periodsTo turn the boiler off set the function selector C to the Oposition. The appliance operation light A will flash every 4se<strong>co</strong>nds.For long periodsWhen you do not expect to use the boiler for a long period:1 Switch the electricity supply off.2 Shut off the gas supply <strong>co</strong>ck and the valves for the watercircuits fitted under the boiler.3 If necessary, empty the water circuits.FROST PROTECTIONThis appliance is provided with a built in anti---freeze systemthat operates the boiler when the temperature is below 5 ûCTherefore, when the boiler is not lit and used in <strong>co</strong>ld weather,with <strong>co</strong>nsequent risk of freezing do not isolate the boilerfrom the electricity supply or close the gas inlet <strong>co</strong>ck.ESCAPE OF GASShould a gas leak or fault be suspected <strong>co</strong>ntact your localgas supplier without delay.Do not search for gas leaks with a naked flame.CLEANINGFor normal cleaning simply dust with a dry cloth.To remove stubborn marks and stains use a damp cloth andmild detergent.Do not use abrasive cleaning materials.MAINTENANCEThe appliance should be serviced at least once a year by aCORGI registered installer.FAULTSNo heating or hot waterCheck that gas and electricity are available at the boiler andthat all switches are on.Check that the system water pressure gauge G reads at least0,5 bar.Check the lock---out signal lamp E. If it is illuminated press theboiler reset button D to restart the ignition sequence.HotwaterbutnoheatingCheck that the programmer and room thermostat (if fitted) areboth calling for heat.Heating but no hot waterCheck that <strong>co</strong>ld water flows out of the taps at a minimum rateof 3.5 litres per minute (or 1 pint in 10 se<strong>co</strong>nds or less). If not,look for stop valves not fully open.Ifthesesimplechecksfailtosolvetheproblem,ortheproblem recurs, <strong>co</strong>nsult your service engineer.

PointsforBoilerUserNote. In line with our current warranty policy we would ask that you check through the following <strong>guide</strong> to identify any problemsexternal to the boiler prior to requesting a service engineers visit. Should the problem be found to be other than with the appliancewe reserve the right to levy a charge for the visit, or for any pre---arranged visit where access is not gained by the engineer.Troubleshooting --- Typical Non Product FaultsProblemBoiler is not working for central heatingor hot waterBoiler goes through ignition sequence butwill not fire for either central heating or hotwater and then goes to ignition lockoutFan & pump run <strong>co</strong>ntinuosly but there is noattemptatignitionOperating for hot water but will not operatefor central heatingSolutionF Is there power to the boiler i.e. is the left hand side green LED (A) alight andflashing every 4 se<strong>co</strong>nds.
