Ideal Boilers Optia HE 9 Installation And Servicing Instructions

8 Optia HE - Installation & ServicingGENERALBathroomsThis range of appliances is rated IP 1XB.The boiler may be installed in any room or internal space, althoughparticular attention is drawn to the requirements of the currentI.E.E. (BS.7671) Wiring Regulations and, in Scotland, the electricalprovisions of the building regulations applicable in Scotland withrespect to the installation of the boiler in a room or internal spacecontaining a bath or shower. For Ireland reference should bemade to the current ETCI rules for electrical installations andI.S.813:2002.If the appliance is to be installed in a room containing a bath orshower then, providing waterjets are not going to be used forcleaning purposes (such as communal baths/showers), theappliance can be installed in Zone 3, as detailed in BS.7671.Where 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 :z BS. 6798.z 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'.z For the minimum clearances required for safety andsubsequent service refer to the wall mounting diagram,Frame 2. In addition, sufficient space may be required to allowlifting 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 governed meter.A gas meter can only be connected by the local gas supplier or bya local regional contractor.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 beavailable at 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 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 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 be protectedby a purpose designed guard.Terminals guards are available from boiler suppliers - ask forTFC Flue Guard, Model No. K6-round, plastic coated. In case ofdifficulty seek advice 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 to preventignition 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 to I.S. 813:2002.IMPORTANT. It is absolutely ESSENTIAL to ensure, in practice, thatproducts of combustion discharging from the terminal cannot re-enter the building or any other adjacent building through ventilators,windows, doors, other sources of natural air infiltration, or forcedventilation/air conditioning.If this should occur, the appliance MUST be turned OFF, labelled'unsafe' and corrective action taken.Flue Terminal Positions Min.
