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 or boundary line 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).

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 a
300
plume of water vapour will be discharged from the
300
flue. This should be taken into account when siting
300
the flue terminal.

25
requirements for siting balanced flue terminals.
(i) 25 (ii) 115
For GB recommendations are given in BS 5440 Pt 1.

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

2. If the terminal discharges onto a pathway or
passageway, check that combustion products will not
1200
cause a nuisance and that the terminal will not obstruct
1500
300
the passageway.
300
3. Take into consideration the effect the plume of
1000
vapour may have on neighbours when siting the flue.
4. 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.
5. For installation of the flue into an internal corner at
the 25mm dimension the flue deflector kit (part no.
248167) must be fitted.
6. * Reduction to the boundary is possible down to
25mm but the flue deflector kit (part no. 248167) must
be fitted.
7. If required a suitable terminal guard is available from
Baxi for use with the flue deflector.
8. 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.
9. If a terminal is less than 2 metres (78
balcony, above ground or above a flat roof to which
people have access, then a suitable terminal guard must
be provided.
