Ideal Boilers Classic LXRS 245 P Installation And Servicing

Classic LXRS, RS - Propane Installation 1315 GAS CONNECTIONA MINIMUM gas pressure of 37 mbar (14.8 in.w.g.) MUST beavailable at the boiler inlet with the boiler operating.The main gas cock is on the left hand side of the gas control valve,as shown (Frame 25).To facilitate connection the gas cock may be removed from the gascontrol valve.16 WATER CONNECTIONS1. Remove the plastic plugs from the flow and returnpipes.2. Make all water connections and check for watersoundness.INSTALLATIONINSTALLATION17 ELECTRICAL CONNECTIONSWARNING . The appliance MUST be efficiently earthed.A mains supply of 230 V ~ 50 Hz is required.All external controls and wiring MUST be suitable for mainsvoltage. Wiring should be in 3-core PVC insulating cable NOTLESS than 0.75 mm2 (24 x 0.2 mm) to BS.6500, Table 16.Wiring external to the boiler MUST be in accordance with currentl.E.E. (BS7671) Wiring Regulations and local regulations.Connection must be made in a way that allows complete isolationof the electrical supply - such as a double pole switch, having a3mm (1/8") contact separation in both poles or a plug and socket,serving only the boiler and system controls. The means ofisolation must be accessible to the user after installation.Note. If the optional Programmer Kit is to be fitted, refer to theinstructions provided with the kit, ignore this frame and go toFrame 18.The internal wiring of the control box is shown in Frame 19.DETAIL OF CONTROL BOX TERMINALSNote. In order to connect the incoming mains wires, firstremove the control box fixing screw then pull the box forwardand downward to disengage.Ensure that the earth lead is longerthan the live and neutral so that if thecable slips in its anchorage thecurrent carrying conductors becometaut before the earth conductor andthat the cable is routed through thestrain relief clamp. Ensure all cablesare secure and that no basicinsulation is accessible outside ofthe control box.3. Controls that switch the circulation pump only ON and OFF, e.g. a roomthermostat, MUST be wired in series with the pump in the live pump lead.4. If a proprietary system is used, follow the instructions supplied by themanufacturer.5. SYSTEM DESIGNS FEATURING CONTROLS OR WIRINGARRANGEMENTS WHICH ALLOW THE BOILER TO FIRE WHENTHERE IS NO PUMPED OR GRAVITY CIRCULATION TAKING PLACESHOULD NOT BE FITTED.Advice on required modifications to the wiring may be obtained from thecomponent manufacturers.Notes1. Connections between a frost thermostat and the timecontrol should be made without disturbing other wiring.2. A frost thermostat should be sited in a cool place in thehouse, but where it can sense heat from the system.LEGENDb bluebr browng/y green/yellow18 EXTERNAL CONTROLSThe wiring diagrams illustrated in Frames 20-23 cover the systemsmost likely to be fitted to this appliance.For wiring external controls to the Classic RS boiler, referenceshould be made to the system wiring diagrams supplied by therelevant manufacturer, in conjunction with the wiring diagramsshown in Frames 19-23.Difficulty in wiring should not arise, providing the following directionsare observed:1. Controls that switch the system ON and OFF, e.g. a timeswitch, MUST be wired, in series, in the live mains lead to theboiler.2. Controls that override an ON/OFF control, e.g. a frostthermostat, MUST be wired into the mains lead, in parallel,with the control(s) to be overridden - refer to Frame 23.19 PICTORIAL WIRINGFLOW WIRING DIAGRAM
