30Response 80 / 100 / 120 - InstallationWARNING . Whilst effecting the required gas soundness test and purging air from the gas installation, open all windows anddoors, extinguish naked lights and DO NOT SMOKE.A. ELECTRICAL INSTALLATION1. Checks to ensure electrical safety should be carried out bya competent person.2. ALWAYS carry out the preliminary electrical system checks,i.e. earth continuity, POLARITY, resistance to earth and shortcircuit, using a suitable test meter.43 COMMISSIONING AND TESTINGINSTALLATIONINSTALLATIONB. GAS INSTALLATIONThe whole of the gas installation, including the meter, shouldbe inspected and tested for soundness and purged inaccordance with the recommendations of BS. 6891.i.e. not less than 5 times the capacity per revolution of the gasmeter mechanism.42 EXTERNAL ELECTRICAL CONTROLSEarths are not shown for clarity but must never be omitted.Wiring External to the BoilerWARNING. This appliance must be efficiently earthed.A mains supply of 230 V ~ 50 Hz is required.The fuse rating should be 3A.Wiring external to the boiler MUST be in accordance with the currentI.E.E. (BS.7671) Wiring Regulations and any local regulations.All external controls and wiring must be suitable for mains voltage.Wiring should be 3 core PVC insulated cable, not less than 0.75 mm2 (24x 0.2mm).Wiring external to the boiler MUST be in accordance with the currentwiring regulations and any local regulations.Connection must be made in a way that allows complete isolation of theelectrical supply such as a double pole switch having a 3mm (1/8")contact separation in both poles, or a plug and socket, serving only theboiler and system controls. The means of isolation must be accessibleto the user after installation.Internal ProgrammerThe Ideal Programmer Kit is supplied with its own instructions.Associated controls should be wired as shown in Diagram A.External Single Channel ProgrammerThis should be wired as shown in Diagram BExternal Two Channel ProgrammerThis should be wired as shown in Diagram C. The power to theprogrammer should be isolated with the same switch that isolates powerto the boiler, otherwise the boiler can be left live, even when the boilerisolating switch is off. Using a two channel programmer will disable theheating switch.N.B.These diagrams are schematic onlyand do not show external terminal strips etc.Room ThermostatIt is recommended to use a room thermostat in conjunction with theboiler to give the most efficient boiler performance and the mostcomfortable central heating performance. The room thermostatshould be wired (depending on the programmer option) as eitherdiagram A, B or C. The boiler will operate without a room thermostatby using the central heating temperature control to vary the flowtemperature between 70 oC and 82 oC (± 5 oC.)Frost ThermostatCentral heating systems fitted wholly inside the house do not normallyrequire frost protection as the house acts as a 'storage heater' andcan normally be left at least 24 hours without frost damage.However, if parts of the pipework run outside the houseor if the boiler will be left off for more than a day or sothen a frost thermostat should be wired into the system.The frost thermostat should be sited in a cold place butwhere it can sense heat from the system.Wiring should be as shown.Note. Ifthe boiler is installed in a garage it may benecessary to fit a pipe thermostat, preferably on thereturn pipework.
