9.6.1 Flue terminal locations
The terminal should be located where dispersal of combustion products is not unimpeded and with due
regardforthedamageordiscolourationthatmightoccurtopartsofthebuildinginthevicinity(seeg
9.6.1.c).
In certain weather conditions condensation may also accumulate on the outside of the air inlet pipe. Such
conditions must be considered and where necessary insulation of the inlet pipe may be required.
Incoldand/orhumidweatherwatervapourmaycondenseonleavingtheueterminal.Thee󰀨ectofsuch
‘plumeing’ must be considered.
The terminal must not be located in a place where it is likely to cause a nuisance, where the terminal is less
than2m(6.6ft)aboveapavementorplatformtowhichpeoplehaveaccess(including)anybalconyorat
roof. The terminal must be protected by a guard of durable material.
Where a terminal is tted below a window which is hinged at the top, and where the hinge axis is
horizontal, and the window opens outwards, the terminal shall be 1m below the bottom of the window
opening.
The ue must be terminated in a place not likely to cause a nuisance.
Forhorizontalueterminaldirecttotherearorsidethroughthewall(only1bend
and1wallterminal)theterminalshouldbeplacedhorizontal.Theuepipeinside
theterminalisttedina3degreesangletoensurethecondensationwatercanrun
backtotheboiler.Seegure9.6.1.a.
Forlongerhorizontalsections,theoutletsystemshouldalwaysbettedonan
incline (52 mm/m = 3°) sloping down towards the boiler so that no condensation
water is able to accumulate in the outlet system. The chances of icicles forming on
the outlet is minimised by causing the condensation water to run back towards the
boiler.Seegure9.6.1.b.
