INSTALLATION INSTRUCTIONS274. COMMISSIONING THE APPLIANCE4.1 General warningsThe following operations must be carried out by professionally qualified personnel and Gas SafeRegistered in accordance with current legislation. Reference should be made to BS 5449:5“Commissioning”.The boiler leaves the factory pre-set and tested for burning either natural Gas or LPG. Nevertheless,when starting the boiler for the first time, make sure that the information on the rating platecorresponds to the type of gas being supplied to the boiler and check that the correct C02 value ispresent as stated in Section 4.5.Once the system has been filled and the necessary adjustments made, remember to tighten thescrews of the gas valve test point and make sure that there are no gas leaks from the test point andfrom any pipe fittings upstream of the gas valve.The BENCHMARK commissioning record contained in this book should be completed.■ Preliminary operationsSwitching the boiler on for the first time means checking that the installation, regulation and operation of theappliance are correct :• If the gas supply system is newly installed, then the air present in the pipes can cause the boiler not to light atthe first attempt. A number of attempts may be required in order to light the boiler;• Check that the data on the data plate corresponds to that of the mains supply networks (gas, electricity, water));• Check that the power supply voltage to the boiler complies with the data plate (230 V – 50 Hz) and that the live,neutral and earth wires are connected properly. Also make sure that the earth connection is sound;• Check the seals on the gas supply pipe from the mains, and make sure that the meter does not register any flowof gas;• Turn the gas supply on and purge according to in GB BS6891.• Test for gas soundness.• Check that the gas supply is correctly sized for the flow rate required by the boiler and that it is fitted with all thesafety and control devices as lay down by current regulations• Check that the supply of combustion air and exhaust and condensate discharge systems are functioningcorrectly and in line with current law and national and local standards;• Check for the presence of permanent aeration/ventilation openings as required by current law for the type ofappliances installed.• Check that the flue duct and its connections to the terminal/chimney comply with the requirements of current lawand national and local standards for the type of appliances installed and are to the manufacturers specification.• Make sure that any central heating isolation valves are open.• Check that the condensate drain system, including outside the boiler (flue system condensate collectiondevices), allows the condensate to flow freely to the collection devices. If the condensate is discharged to thedomestic drainage system, install an inspection trap in the condensate system prior to it entering the drainagesystem to interrupt the continuity between the two systems.• Check that there are no exhaust fumes discharged into the condensate drain system itself.• Check that there are no flammable materials or liquids in the immediate vicinity of the boiler;• Flush out both primary and domestic hot water circuits (see 4.3 “ Flushing the system”).
