NOTE:
All measurements are the minimum clearances required.
Terminals must be positioned so to avoid combustion
products entering the building.
Key to illustration
1. 600 mm distance to a boundary, unless it will cause a nuisance.
BS 5440: Part 1 recomends that care is taken when siting
terminals in relation to boundaries.
2. Internal/external corners the air intake can be reduced
to150mm providing the flue exhaust outlet has a 300mm
clearance.
3. The flue cannot be lower than 1,000mm from the top of the
light well due to the build up of combustion products.
4. 1,200mm between air intake and facing terminal.
5. Clearance no less than 200mm from the lowest point of the
balcony or overhang, installations in car ports are not
recommended.
6. 1,200mm from an opening in a car port on the same wall
i.e. door or window leading into dwelling. 600mm to a surface

7. Using a Plume Management Kit the air intake measurement
can be reduced to 150mm providing the flue exhaust outlet
has a 300mm clearance.
Plume kits running horizontally must have a 10 degree fall
back to the boiler for proper disposal of condensate.
For details on specific lengths see relevant boiler Technical &
Specification manual.
8. This allows some basic plume options on a standard telescopic
horizontal flue terminal. 300mm minimum clearances to a
opening e.g. window.
However the minimum clearance to an opening in the direction
to which the plume is directed in, should be increased to
1,500mm.
Where the flue is less than 150mm to a drain pipe & the plume
deflector is used it should not be directed towards it.
