NOTICE:
B All measurements are the minimum clearances required.
B Refer to figure 18 for all concentric flue terminal positions unless the flue position is specified on the
figure above "Plume terminal positions".
B Terminals must be positioned so to avoid combustion products entering the building.
B Support the flue at approximately one metre intervals and at a change of direction, use suitable
brackets and fittings.
Key to illustration
1. 600 mm distance to a boundary or surface facing a
boundary, unless it will cause a nuisance. BS 5440:
Part 1 recommends that care is taken when siting
terminals in relation to boundaries.
2. Internal/external corners. The air intake clearance can
be reduced to 150 mm providing the flue exhaust
outlet has a 300 mm clearance.
3. The flue cannot be lower than 1,000 mm from the
top of the light well due to the build up of
combustion products.
4. 1,200 mm between air intake and facing terminal.
5. Clearance no less than 200 mm from the lowest
point of the balcony or overhang.
Installations in car ports are not
recommended.
6. 1,200 mm from an opening in a car port on the same
wall i.e. door or window leading into dwelling.

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