Regulation
Only fl ue accessories supplied by Heatline must
be used. NOTE: In accordance with Building
Regulations Part J: 2010 and the Gas Safe
Register Technical Bulletin TB 008: For Boiler
fl ue systems installed within any concealed
enclosure (such as a ceiling space, fl oor void,
or a purpose built enclosure), the entire fl ue
system should be accessible. This is to allow
proper inspection of the fl ue to determine that it
is continuous and fully supported throughout its
length and all joints are correctly assembled.
Please refer to section 9.2, which describes the fl ue types
available.
• Consult your supplier for more information about the other
possibilities and associated accessories.

• 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 fl ue instructions.
• Explain these requirements to the user of the appliance.

If necessary, you must install a fl ue terminal
guard.
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. If the carport
comprises of a roof and two or more walls, seek advice from the
local gas supply company before installing the boiler.
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.
