The terminal must be positioned such that the prod-ucts of combustion can disperse freely at all times.b. A plume of water vapour will sometimes be visiblefrom the flue terminal. Positions where this could bea nuisance should be avoided.c. If the terminal is fitted less than 2 m above a balcony,above ground or above a flat roof to which people haveaccess then a suitable terminal guard must be provided andfitted (contact Tower Flue Components, Tonbridge, TN9 1TB).Note!Vertical flues must not terminate within 600mm of an openable window, air vent or anyother ventilation opening.The flue assembly shall be so placed or sheilded as toprevent ignition or damage to any pary of the building.Note!In addition, the terminal should not be nearerthan 150 mm to an opening in the building fab-ric formed for the purpose of accommodating abuilt–in element such as a window.BS 5440–1 It is recommended that the fanned flue ter-minal should be positioned as follows:a) at least 2m from an opening in the building directlyopposite, andb) so that the products of combustion are not directlydirected to discharge across a boundary.1) Dimensions B, C and D:These clearances may be reduced to 25 mm withoutaffecting the performance of the boiler. In order toensure that the condensate plume does not affectadjacent surfaces the terminal should be extended asshown in fig. 4.8.2) Dimension F:This clearance may be reduced to 25 mm withoutaffecting the performance of the boiler. However, inorder to ensure that the condensate plume does notaffect adjacent surfaces a clearance of 300 mm ispreferred.
