Horizontally from a terminal on the wall 300 mm (12")Table 3 - Balanced flue terminal position4. 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 seekadvice from: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 aplastic or painted gutter or 500mm (19 1/2 ") of painted eavesthen an aluminium shield at least 1000mm (39 1/2 ") longshould be fitted to the underside of the gutter or paintedsurface.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: 1990.the electrical 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, provided it ismodified for the purpose.In both cases details of essential features of cupboards/compartment design, including airing cupboard installation, are toconform 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, see section on 'Air Supply'.z For the minimum clearances required for safety andsubsequent service, see the Wall mounting diagram, Frame2. In addition, sufficient space may be required to allow liftingaccess to the wall mounting plate.GAS SUPPLYA local propane supplier should be consulted, at the installationplanning stage, in order to establish the availability of an adequatesupply of gas.Installation pipes, cylinders and pressure regulators MUST be fittedin accordance with BS. 5482.1.Pipework from the supply to the boiler MUST be of an adequatesize.Bulk tank installations must comply with the Home Office code ofpractice for the storage of liquefied petroleum gas at fixedinstallations.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 therecommendations of BS. 5440:1.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 3.7. 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 air infiltration,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 10 'Unpacking'.
