7Minimiser SE - InstallationBathroom InstallationsThe 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, theelectrical provisions of the building regulations applicable inScotland with respect to the installation of the boiler in a room orinternal space containing a bath or shower.Where a room sealed appliance is installed in a room containinga bath 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, specialprocedures may be necessary and BS 6798 gives detailedguidance on this aspect.Compartment InstallationsA compartment used to enclose the boiler should be designedand constructed specially for this purpose.An existing cupboard or compartment may be used, providedthat it is modified for the purpose.In both cases details of essential features of cupboard /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. Ventilation of thecompartment is not necessary.z For the minimum clearances required for safety andsubsequent service, see the wall mounting template andFrame 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.A gas meter can only be connected by the local gas supplier or bya registered CORGI installer.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. A minimum working gas pressure of20 mbar MUST be available at the boiler inlet.Installation pipes MUST be fitted in accordance with BS. 6891.Pipework from the meter to the boiler MUST be of an adequatesize, i.e. not less than 15mm O.D. Note. For pipe runs greaterthan 3m (10'), 22mm O.D. pipe must be used.Do not use pipes of smaller size than the boiler inlet gasconnection.The complete installation MUST be tested for gas soundnessand purged as described in the above code.FLUE INSTALLATIONPluming will occur at the termination so, where possible, terminalpositions which could cause a nuisance should be avoided.The flue must be installed in accordance with therecommendations of BS. 5440: Part 1.GENERALThe 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 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 - ask forTower Flue Guard, Model K1. In case of difficulty seek advicefrom:Tower Flue Components Ltd.,Vale Rise, Tonbridge, Kent TN9 1TBTelephone No. 01732 351 555.Ensure that the guard is fitted centrally.5. Where the terminal is fitted within 850mm (34") of a plastic orpainted gutter or 450mm (18") of painted eaves then analuminium shield at least 750mm (30") long should be fittedto 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 610mm (24") or with an inaccuratelycut hole, the minimum spacing in Table 3, Nos. 2, 3, 4, 5 and6 would be 60mm (2.4") in order to allow the terminal wallTerminal Position Minimum Spacing1. Directly below or alongside anopening window, air vent or other 300 mm (12")ventilation opening2. 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")Table 3 - Balanced flue terminal positionNote positions 2-6: Due to the terminal design, installation ispossible with clearances less than those specified in BS 5440,Part 1.
