• Standard fl ue terminal kits have an in-built fall back to the
boiler to drain the condensate. These can be fi tted level
between the appliance and the termination position. All other
extended fl ues must have a fall of at least 44mm/m
The maximum length of the fl ue outlet is defi ned according to its
type (for example C13).
• Whatever the kind of fl ue system chosen, observe the
minimum distances indicated in the chart below to position
the fl ue terminals.
• To install the fl ue, refer to the separate fl ue instruction
supplied with your appliance.
• Explain these requirements to the user of the appliance.
a
DANGER:
If necessary, you must install a fl ue terminal guard.
b
ATTENTION:
Caution! The connection between the fl ue elbow and the
fl ue outlet must be sealed.
In GB the minimum acceptable siting dimensions for the terminal
from obstructions, other terminals and ventilation openings are
shown in diagram overleaf.
In IE the minimum distances for fl ue terminal positioning must be
those detailed in I.S.813 “Domestic Gas Installations”.
The terminal must be exposed to the external air, allowing free
passage of air across it at all times.
Being a condensing boiler some pluming may occur from the fl ue
outlet. This should be taken into consideration when selecting
the position for the terminal.
Carports or similar extensions of a roof only, or a roof and one
wall, require special consideration with respect to any openings,
doors, vents or windows under the roof. Care is required to
protect the roof if made of plastic sheeting. A carport is defi ned
as a roof and one wall.
b
ATTENTION:
If the fl ue terminal is positioned near a light source
insects may enter the fl ue system. Where safe and
practical to do so advise the homeowner to check the
fl ue outlet and clear visible insects from the terminal
end.
