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effectofsuch
‘plumeing’ must be considered.
The terminal must not be located in a place where it is likely to cause a nuisance.
For protection of combustibles, refer to IS 813 section 9.10.1. 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.
If the boiler is to be located under stairs, a smoke alarm meeting the requirements of I.S. 409 or
equivalent must be tted.
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.
