6Classic FF 340 - 360 LF - Installation & ServicingGENERALWhere installation will be in an unusual location, specialprocedures may be necessary and BS.6798 gives detailedguidance on this aspect.Compartment InstallationsA compartment used to enclose the boiler MUST be designedand constructed specially for this purpose.An existing cupboard or compartment may be used, provided itis modified for the purpose.In both cases details of essential features of cupboards/compartment design, including airing cupboard installation, areto conform to the following :! BS. 6798.! The position selected for installation MUST allow adequatespace for servicing in front of the boiler and for air circulationaround the boiler. Refer to 'Air Supply' on page 7.! For the minimum clearances required for safety andsubsequent service refer to the wall-mounting diagram,Frame 2. In addition, sufficient space may be required toallow lifting access to the wall mounting plate.GAS SUPPLYThe local gas supplier should be consulted, at the installationplanning stage, in order to establish the availability of an adequatesupply of gas. An existing service pipe must NOT be used withoutprior consultation with the local gas supplier.The boiler is to be installed only on a gas supply with a governedmeter.A gas meter can only be connected by the local gas supplier or aCORGI registered engineer. In IE by a Competent Person.An existing meter should be checked, preferably by the gas supplier,to ensure that the meter is adequate to deal with the rate of gassupply required. A MINIMUM pressure of 20 mbar MUST be availableat the boiler inlet with the boiler operating.Installation pipes MUST be fitted in accordance with BS. 6891. InIE refer to I.S. 813:2002. Pipework from the meter to the boilerMUST be of an adequate size.The complete installation MUST be tested for gas soundness andpurged as described in the above code.FLUE INSTALLATIONPluming may occur at the terminal so terminal positions whichwould cause a nuisance should be avoided.The flue must be installed in accordance with therecommendations of BS.5440-1: 2000. In IE refer to I.S. 813:2002.The following notes are intended for general guidance:-1. The boiler MUST be installed so that the terminal is exposed toexternal air.2. It is important that the position of the terminal allows the freepassage of air across it at all times.3. Minimum acceptable spacing from the terminal to obstructionsand ventilation openings are specified in Table 3.4. Where the lowest part of the terminal is fitted less than 2m(6'6") above a balcony, above ground or above a flat roof towhich people have access then the terminal MUST beprotected by a purpose designed guard. The minimumspacing in Table 3, Nos. 2,3, 4, 5 and 6 would be 75mm inorder to allow a terminal guard to be fitted.Terminals guards are available from boiler suppliers - askfor TFC Flue Guard, Model K1. In case of difficulty seekadvice from:Grasslin (UK) Ltd., Tower House, Vale Rise, Tonbridge,Kent TN9 1TB.Tel: +44 (0) 1732 359 888. Fax: +44 (0) 1732 354 445www.tfc-group.co.ukEnsure that the guard is fitted centrally.5. The flue assembly shall be so placed or shielded as toprevent ignition or damage to any part of any building.6. The air inlet/products outlet duct and the terminal of the boilerMUST NOT be closer than 25mm (1") to combustible material.Detailed recommendations on the protection of combustiblematerial are given in BS.5440-1:2000. In IE refer toI.S.813:2002.7. Where it is essential that the terminal wall plate is fitted, i.e.wall thicknesses over 600mm (23 1/2 ") or with an inaccuratelycut hole, the minimum spacing in Table 3 Nos. 2,3, 4, 5 and 6would be 60mm (2 1/2 ") in order to allow the terminal wall plateto be fitted.IMPORTANT. It is absolutely ESSENTIAL to ensure, in practice,that products of combustion discharging from the terminal cannotre-enter the building or any other adjacent building throughventilators, windows, doors, other sources of natural airinfiltration, or forced ventilation/air conditioning.If this should occur, the appliance MUST be turned OFF, labelled'unsafe' and corrective action taken.TERMINALThe terminal assembly can be adapted to accommodatevarious wall thicknesses.
