6 Classic FF - Installation & ServicingGENERALWhere a room-sealed appliance is installed in a room containing abath or shower then the appliance and any electrical switch orappliance control utilising mains electricity should be so situatedthat it cannot be touched by a person using the bath or shower.Where installation will be in an unusual location, special proceduresmay be necessary and BS.6798 gives detailed guidance on thisaspect.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 it ismodified for the purpose.In both cases details of essential features of cupboards/compartmentdesign, including airing cupboard installation, are to conform to thefollowing :z BS. 6798.z The position selected for installation MUST allow adequate spacefor servicing in front of the boiler and for air circulation aroundthe boiler. Refer to 'Air Supply' on page 7.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 governedmeter.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 be availableat the boiler inlet with the boiler operating.Installation pipes MUST be fitted in accordance with BS. 6891.Pipework from the meter to the boiler MUST be of an adequatesize. FF2 100 models should be piped in 22mm minimum. The final1metre may be run in 15mm if it is visible.The complete installation MUST be tested for gas soundness andpurged as described in the above code.FLUE INSTALLATIONThe flue must be installed in accordance with the recommendationsof BS. 5440:1.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 to whichpeople have access then the terminal MUST be protected bya purpose designed guard. The minimum spacing in Table 3,Nos. 2,3, 4, 5 and 6 would be 75mm in order to allow a terminalguard to be fitted.Terminals guards are available from boiler suppliers - ask forTower Flue Guard, Model K1. In case of difficulty seek advicefrom:Tower Flue Components Ltd.,Vale Rise, Tonbridge, Kent TN9 1TB (Model K1)Telephone No. 01732 351 555Ensure that the guard is fitted centrally.5. Where the terminal is fitted within 1000mm (39 1/2 ") of a plasticor painted gutter or 500mm (19 1/2 ") of painted eaves then analuminium shield at least 1000mm (39 1/2 ") long should befitted to the underside of the gutter or painted surface.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: 1990.7. 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 accommodate variouswall thicknesses. Refer to Frame 8.AIR SUPPLYDetailed recommendations for air supply are given in BS.5440:2.The following notes are for general guidance:Table 3 - Balanced flue terminal positionTerminal Position Minimum Spacing1. Directly below or alongside anopening window, air vent or otherventilation opening 300 mm (12")2. Below guttering, drain pipes or soilpipes 25 mm ( 1")3. Below eaves 25 mm ( 1")4. Below balconies or a car port roof 25 mm ( 1")5. From vertical drain pipes or soil pipes 25 mm ( 1")6. From internal or external corners 25 mm ( 1")7. Above adjacent ground, roof orbalcony level 300 mm (12")8. From a surface facing the terminal 600 mm (24")9. From a terminal facing a terminal 1200 mm (48")10. From an opening in a car port(e.g. door or window) into dwelling 1200 mm (48")11. Vertically from a terminal on thesame wall 1500 mm (60")12. Horizontally from a terminal on the wall 300 mm (12")
