No. ........ 87 AS 94INTRODUCTIONResponse combi boilers are wall mounted, low water content,fanned flue combination gas boilers of type C 13 intended for usewith gas group I2 H.Central heating (CH) output modulates between 11.7 kW (40,000Btu/h) minimum and 23.4 kW (80,000 Btu/h) maximum forResponse 100/120 and 17.6kW (60 000Btu/h) maximum forResponse 80.Domestic hot water (DHW) output is also fully modulating, with amaximum of:Response 80 23.4 kW (80,000 Btu/h)Response 100 29.3 kW (100,000 Btu/h)Response 120 35.2 kW (120,000 Btu/h).The boiler is suitable for connection to fully pumped, pressurisedsealed water systems ONLY.A system bypass is only required when TRV's are fitted to allradiators (see Frame 5).Boilers are supplied fully assembled and, being a 'tube-within-tube' design, require no diverter valve or domestic hot water calorifier.A circulating pump, pressure gauge, safety valve and expansionvessels for both central heating (CH) and domestic hot water (DHW)are provided.The CH flow temperature is controlled by an electronic thermostat.In DHW mode the boiler modulates to sustain a nominal adjustablewater flow temperature of 60 oC.The boiler casing is of white painted mild steel with a drop-downcontrols access door.The boiler temperature control is located behind the controls accessdoor.The heat exchanger is made of copper and cast iron.The system pipework must include drain cocks in appropriateplaces. Pipework may be taken downwards or upwards behindthe boiler (using the stand-off channels).OPTIONAL EXTRA KITSProgrammer Kit - fits neatly within the casing. Separate fittinginstructions are included with the kit.Note.If using an alternative programmer read Frame 42 first.Extension DuctsRoof Flue kit90oElbow kit45oElbow kitPowered Vertical Flue kitNote.When ordering Pack H or Pack K flue adaptor mustbe used.Destination Countries: GB and IE.CONTENTSAir Supply ....................................................................... 7Boiler Dimensions/Clearances ..................................... 6Boiler Exploded Diagram ............................................ 12Commissioning and Testing ....................................... 30Electrical Connections ................................................ 28Electrical Diagrams ..................................................... 28Electrical Supply Requirements ................................... 9Extension Ducts - Fitting ............................................. 25Fault Finding ................................................................. 49Flow Wiring Diagram ................................................... 28Flue FittingRear outlet .............................................................. 15Side outlet .............................................................. 20Flue Installation Requirements ..................................... 8Gas Safety Regulations ................................................. 7Gas Supply Requirements ............................................ 8Initial Lighting ............................................................... 31Installation ................................................................... 12Mandatory Requirements ............................................. 7Sealed System Requirements ...................................... 9Servicing ...................................................................... 33Short List of Parts ....................................................... 60Terminal Guards ............................................................ 8Thermostatic Radiator valves ...................................... 9Unpacking .................................................................... 13Water and Systems ...................................................... 8Water Connections ...................................................... 6Water Treatment ........................................................... 9Wiring Diagrams .......................................................... 28NOTE TO THE INSTALLER: LEAVE THESEINSTRUCTIONS ADJACENT TO THE GAS METER.ALSO COMPLETE THE BENCHMARK LOG BOOKAND GIVE THIS TO THE CUSTOMER.Data badge: top RH controls channel
