General safety information

> Before installing the flue pipe, you must inform the local
gas supply company and the master chimney sweep for
the district.
Qualification of the competent persons
The installation of the boiler and its flue must be carried
out by a competent person approved at the time by the
Health and Safety Executive. This competent person is also
responsible for proper execution. They must also comply
with the existing directives, regulations and guidelines.
Dangers caused by flue gas exit in the event of
improper installation.
In the event of improper installation, there is a risk that poi-
sonous gases may be emitted.
> Ensure that the installation is performed only by quali-
fied competent persons.

Explanation
Imminent danger to life or risk
of severe personal injury
Risk of death from electric
shock
Risk of minor personal injury
Risk of material or environ-
mental damage
Risk of death by poisoning due to escaping flue
gases!
All openings in the flue pipe that can be opened for inspec-
tion purposes must be closed before start-up and during
operation.
> The openings must only be opened by a competent person.
For open-flued operation, the unit must not be placed in
rooms from which the air is extracted using fans (for exam-
ple, ventilation systems, extractor hoods, tumble dryer ven-
tilation). These systems generate negative pressure in the
room. This negative pressure can cause flue gas to be
sucked into the installation room from the opening through
the annular clearance between the flue gas pipe and the
shaft. The unit can be used in open-flued operation if simul-
taneous operation of the unit and the fan is not possible.
Avoid risk of suffocation!
If the flue gas pipe is not concentric and is therefore not
ventilated from behind, there is a danger of suffocation in
unventilated rooms.
> These rooms must be equipped with a ventilation open-
2
ing of 150 cm that leads into the fresh air.
Prevent injuries caused by snow falling from roofs
Where flue pipes penetrate the roof skin, the water vapour
contained in flue gas may precipitate as ice on the roof or
the roof structures in unfavourable weather conditions.
> At the installation site, ensure that this ice build-up does
not slide from the roof.
Use of tools
Unsuitable tools or the improper use of tools can cause
damage (e. g. to casing and components).
> Always use appropriate screwdrivers or open-end span-
ners (fork wrenches) to loosen or tighten threaded con-
nections.
> Never use pipe wrenches, extensions, or other similar
tools.
Preventing the risk of corrosion in the flue gas
installation
Sprays, solvents, cleaning agents, paints and adhesives may
contain substances that could lead to corrosion in the flue
gas installation in some circumstances when the unit is in
operation.
> Only use appropriate Vaillant components for installing
the flue gas guiding.
> Ensure that the combustion air that is guided to the unit
is kept free of chemical substances that could contain,
e. g. fluorine, chlorine, or sulphur.
Preventing electronic damage and risk of fire
caused by lightning
The unit can be damaged by the effects of lightning.
> If the building is equipped with a lightning protection
system, incorporate the air/flue gas pipe into the light-
ning protection.
> If the vertical flue gas pipe contains materials made from
metal, incorporate it into the potential balancing.
