32Response 80 / 100 / 120 - Installation45 GENERAL CHECKS1. Hand the User's Instructions to the householder andexplain his or her responsibilities under current GasSafety (Installation and Use) Regulations, or rules inforce.2. Draw attention to the Lighting Instruction label affixed tothe inside of the lower front door.3. Explain and demonstrate the lighting and shutting downprocedures.4. The operation of the boiler and the use and adjustment ofALL system controls should be fully explained to thehouseholder, to ensure the greatest possible fueleconomy consistent with household requirements of bothheating and hot water consumption.5. Advise the user of the precautions necessary to preventdamage to the system and to the building, in the event ofthe system remaining inoperative during frosty conditions.After completing the installation and commissioningof the system, the installer should hand over to thehouseholder by the following actions:46 HANDING OVERINSTALLATIONINSTALLATION Response 80 43.1 to 47.7 litres per minute1.52 to 1.68 cu/ft per minuteResponse 100 51.9 to 57.4 litres per minute1.8 to 2.0 cu/ft per minuteResponse 120 64.8 to 71.6 litres per minute2.28 to 2.52 cu/ft per minutechecked at the gas meter, with no other appliance in use.These figures apply at the nominal UK mains voltage of230V.Note.Long flue will reduce air flow, reducing the gas rate,slightly. If these rates are not obtainable consult the faultfinding section.4. Water circulation systemNote.Fernox Superfloc flushing solution should be usedduring the flushing procedure.a. With the system HOT examine all water connectionsfor soundness.b. With the system still HOT, turn off the gas, water andelectricity supplies to the boiler and drain down, tocomplete the flushing process.c. Refill the system, adding inhibitor (see 'WaterTreatment'), if required.Vent as necessary to clear all air and, again, check forwater soundness. After venting, repressurise asrequired.d. Balance the system.It is suggested that, initially, allradiator handwheel valves (or TRVs if fitted) beset fully open, that all lockshield valves be set ahalf-turn open and the bypass a half-turn to oneturn open (a minimum of one turn open isrecommended when TRVs are used.)Make minor adjustments to each radiator to achievethe same differential on all.Lastly, set the bypass to eliminate any boiler noise,without compromising radiator temperatures.5. Finally, set the system controls to the user’s requirements.6. Remove the labels from the casing front panel.If an optional programmer kit is fitted refer to theinstructions supplied with the kit.6. If a programmer kit is fitted, draw attention to theProgrammer Kit User's Instructions and hand them to thehouseholder.7. After installation, commissioning and customer hand-overinstructions please complete the appliance logbook and leave this with the customer.8. Stress the importance of regular servicing by a CORGIregistered installer and that a comprehensive serviceshould be carried out AT LEAST ONCE A YEAR.9. Demonstrate how to repressurise the boiler when thesystem pressure falls below 0.5 bar.10. Emphasise to the user that the boiler may stopworking if the system pressure is lowered by drainingradiators to decorate behind them. In particular, explainto the user how the domestic hot water temperaturevaries with flow rate. This is especially important whenwater is drawn off while the boiler is already running forcentral heating (refer to 'CAUTION' in User'sInstructions, page 2).Make the following checks for correct operation:1. Hot watera. Fully open all DHW taps in turn and ensure that waterflows freely from them.b. Close all taps except the furthest one from the boilerand check that the boiler is firing at maximum rate.c. Check DHW flow rate and ADJUST to requirementswith boiler cold.To obtain best overall summer and winter watertemperature and flow Caradon recommend setting ata temperature rise = 40oC . See Table below.d. Turn off the DHW tap.Model Flow rate litres/min.
