Terminal Position with Minimum Distance (Fig. 10)
A a Directly below an opening, air brick, opening
windows, etc.
B a Above an opening, air brick, opening window etc.
C a Horizontally to an opening, air brick, opening window etc.
D Below gutters, soil pipes or drain pipes.
E Below eaves.
F Below balconies or car port roof.
G From a vertical drain pipe or soil pipe.
H From an internal (i) or external (ii) corner.
I Above ground, roof or balcony level.
J From a surface facing a terminal.
K From a terminal facing a terminal (Horizontal flue).
From a terminal facing a terminal (Vertical flue).
L From an opening in carport (e.g. door, window)
into the dwelling.
M Vertically from a terminal on the same wall.
N Horizontally from a terminal on the same wall.
R From adjacent wall to flue (vertical only).
S From an adjacent opening window (vertical only).
Table. 1
a In addition, the terminal should be no nearer than 150 mm to an
opening in the building fabric formed for the purpose of accommodating
a built-in element such as a window frame. See BS 5440 Pt. 1.
NOTE: The distance from a fanned draught appliance
terminal installed parallel to a boundary may not be less
than 300mm in accordance with the diagram below

NOTE: Due to the high efficiency of the boiler
300
a plume of water vapour will be discharged
300
from the flue. Take into consideration the
300
effect the plume of vapour may have on

neighbours when siting the flue.

1. The following guidelines indicate the general
25
(i) 25 (ii) 115
requirements for siting balanced flue terminals.
300
For GB recommendations are given in BS 5440

Pt 1. For IE recommendations are given in the
1200
current edition of I.S. 813 "Domestic Gas
600
Installations".

2. If the terminal discharges onto a pathway or
1500
passageway, check that combustion products will
300
not cause a nuisance and that the terminal will
300 not obstruct the passageway.
1000
3. Adjacent surfaces close to the flue terminal
may need protection from the effects of
condensation. Alternatively a flue deflector kit
(part no. 248167) is available.
4. For installation of the flue into an internal
corner at the 25mm dimension the flue deflector
kit (part no. 248167) must be fitted.
5. * Reduction to the boundary is possible down
to 25mm but the flue deflector kit (part no.
248167) must be fitted.
6. For fitting under low soffits and eaves it is
acceptable for the flue to project upto 500mm
from the face of the wall to the inside of the air
intake. This can be painted if required using a
suitable external paint.
7. If a terminal is less than 2 metres (78
above a balcony, above ground or above a flat
roof to which people have access, then a suitable
terminal guard must be provided.
