Flue Terminal Positions - Worcester GREENSTAR 25Si Instruction Manual

• The flue must be fitted and terminated in
accordance with the recommendations of
BS5440 : Part 1.
• The flue must not cause an obstruction.
• Discharge and any noise from the flue outlet
must not cause a nuisance.
• Flue gases have a tendency to plume and in
certain weather conditions a white plume of
condensation will be discharged from the
flue outlet. Where this could be a nuisance,
for example, near security lighting, an alter-
nate position should be found.
• The air inlet/outlet duct and the terminal of
the boiler must not be closer than 25mm to
any combustible material.
Detailed recommendations on protection of
combustible materials are given in
BS 5440: Part 1
• A protective terminal guard must be fitted if
the terminal is 2m or less above a surface to
which people have access.
The guard must be spaced equally (mini-
mum 50 mm) around the flue and fixed to
the wall with plated screws. See Contact
