8 isar + programmer - Installation and ServicingGENERALz For the minimum clearances required for safety andsubsequent service, see the wall mounting template andFrame 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 anadequate supply of gas. An existing service pipe must NOT beused without prior consultation with the local gas supplier.The boiler MUST be installed on a gas supply with a governedmeter only.A gas meter can only be connected by the local gas supplier orby a CORGI registered engineer. In IE by a competent person.An existing meter should be checked, preferably by the gassupplier, to ensure that the meter is adequate to deal with therate of gas supply required.N.B. The principle of the 1:1 gas valve ensures that the isarHE range is able to deliver it’s full output at inlet pressuresdown to 14mb. However if dynamic pressures below 20mb areexperienced ensure this is adequate for ALL other gasappliances in the property.IMPORTANT.Installation pipes must be fitted in accordance with BS.6891. InIE refer to IS.813:2002. Pipework from the meter to the boilerMUST be of an adequate size, i.e. no longer than 20m and notless than 15mm O.D.The complete installation MUST be tested for gas soundnessand purged as described in the above code.FLUE INSTALLATIONPluming will occur at the terminal so terminal positions wherethis could 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 exposedto external 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 toobstructions and ventilation openings are specified inTable 4.4. 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.Terminal guards are available from boiler suppliers. (Ask forTFC flue guard model no. K6 - round, plastic coated). Incase of difficulty contact:Grasslin (UK) Ltd. Tel. + 44 (0) 01732 359 888Tower House, Vale Rise Fax. + 44 (0) 01732 354 445Tonbridge. Kent TN9 1TB www.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 theboiler MUST NOT be closer than 25mm (1") to combustiblematerial. Detailed recommendations on the protection ofcombustible material are given in BS. 5440-1:2000.IMPORTANT. It is absolutely essential to ensure, in practice,that products of combustion discharging from the terminalcannot re-enter the building or any other adjacent buildingthrough ventilators, windows, doors, other sources of naturalair infiltration, or forced ventilation / air conditioning.If this should occur the appliance MUST be turned OFF,labelled as 'unsafe' until corrective action can be taken.TERMINALThe terminal assembly can be adapted to accommodatevarious wall thicknesses. Refer to Frame 12 .AIR SUPPLYIt is NOT necessary to have a purpose-provided air vent in theroom or internal space in which the boiler is installed. Neitheris it necessary to ventilate a cupboard or compartment in whichthe boiler is installed, due to the low surface temperatures ofthe boiler casing during operation; therefore the requirementsof BS 6798, Clause 12, and BS 5440:2 may be disregarded.WATER CIRCULATION SYSTEMIMPORTANT.A minimum length of 1 metre of copper pipe MUST be fitted toboth flow and return connections from the boiler beforeconnection to any plastic piping.The central heating system should be in accordance withBS.6798 and, in addition, for smallbore and microboresystems, BS.5449.WATER TREATMENT - see Frame 6Flue Terminal Positions Min.
