5.3.7 Flue/Chimney Location

1. The following guidelines indicate the general requirements for siting balanced flue terminals.
For GB recommendations are given in BS 5440 Pt 1.
For IE recommendations are given in the current edition of I.S. 813 "Domestic Gas Installations".
Under car ports we recommend the use of the plume displacement kit.
The terminal position must ensure the safe and nuisance - free dispersal of combustion products.
Fig. 11
Terminal Position with Minimum Distance
1
Directly below an opening, air brick, opening windows, etc.
A
1 Above an opening, air brick, opening window etc.
B
1 Horizontally to an opening, air brick, opening window etc.
C
2
Below gutters, soil pipes or drain pipes.
D
E 2 Below eaves.
2 Below balconies or car port roof.
F
2
From a vertical drain pipe or soil pipe.
G
2 From an internal or external corner.
H
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).
T Adjacent to windows or openings on pitched and flat roofs
U Below windows or openings on pitched roofs
1
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.
2
Only ONE 25mm clearance is allowed per installation. If one of the dimensions D, E, F, G or H is 25mm then the remainder MUST be as shown in brackets, in accordance with
B.S.5440-1.

Due to the nature of the boiler a plume of water vapour will be discharged from the flue.
This should be taken into account when siting the flue terminal.
2. If the terminal discharges onto a pathway or passageway, check that combustion products will not cause a nuisance and that the terminal will not obstruct the passageway.
3. If a terminal is less than 2 metres above a balcony, above ground or above a flat roof to which people have access, then a suitable terminal guard must be provided.
4. The distance from a fanned draught appliance terminal installed parallel to a boundary may not be less than 300mm in accordance with the diagram opposite
Reduction to the boundary is possible down to 25mm but flue deflector part no. 5111068 or the appropriate Plume Displacement Kit must be used.
The nuisance factor must still be taken into account when these options are being considered.
