• Standard flue terminal kits have an in-built fall back to the
boiler to drain the condensate. These can be fitted level
between the appliance and the termination position. All other
extended flues must have a fall of at least 44mm/m
The maximum length of the flue outlet is defined according to its
type (for example C13).
• Whatever the kind of flue system chosen, observe the
minimum distances indicated in the chart below to position
the flue terminals.
• To install the flue, refer to the separate flue instruction
supplied with your appliance.
• Explain these requirements to the user of the appliance.
a If necessary, you must install a terminal
protection kit.
b Caution! The connection between the flue elbow
and the flue 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 flue 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 flue 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. If the carport
comprises of a roof and two or more walls, seek advice before
installing the boiler.
b
If the flue terminal is positioned near a light
source insects may enter the flue system.
Where safe and practical to do so advise the
homeowner to check the flue outlet and clear
visible insects from the terminal end.
