1.3 Applicability of the manual
This installation manual applies exclusively to the
Vaillant appliances listed in the other applicable docu-
ments.
2 Description of the appliance
2.1 CE label
The ecoCRAFT VKK 806/3-E, VKK 1206/3-E,
VKK 1606/3-E, VKK 2006/3-E, VKK 2406/3-E and
VKK 2806/3-E gas fired condensing boilers have been
certified in accordance with the EU Gas Equipment Di-
rective 90/396/EWG as heating boiler systems with an
associated flue gas installation and as a boiler of type
C63.
2.2 Intended use
Vaillant gas-fired high efficiency boilers ecoCRAFT VKK
806/3-E, VKK 1206/3-E, VKK 1606/3-E und VKK
2006/3-E, VKK 2406/3-E and VKK 2806/3-E are con-
structed in accordance with state of the art technology
and recognised safety regulations.
The air/flue gas pipe is designed to remove exhaust gas
and to supply combustion air. In case of improper non-
conventional use of air and exhaust pipes in connection
with appliance types, damage can be caused to the
health and body of the user and others respectively
other devices or material assets can be affected.
The dimensioning of the air/flue gas pipes tested with
the respective high efficiency boiler must be carried out
by means of the tables in the following chapters.
Any other or additional use is considered to be improper
and will relieve the manufacturer or supplier of any re-
sponsibility or liability for damage that may result. In
such cases the risk is borne solely by the technician car-
rying out the work and the user. Intended use also in-
cludes the observance of the other applicable docu-
ments.
3 Safety instructions/regulations
3.1 Safety instructions
Before installing the flue pipes you must inform the
local gas supply company and the regional chimney
sweep.
dDanger!
Danger of poisoning from exhaust gas leakage if
installed incorrectly!
The flue gas system may only be installed by a
suitably qualified heating engineer. He will also
assume responsibility for proper installation.
Furthermore, the rules, regulations and guide-
lines mentioned in this installation manual are
to be observed.
Danger!
Risk to life from poisoning as a result of escap-
ing flue gases!
All openings in the flue pipe that can be opened
for inspection purposes must be closed before
start-up and during operation. The openings
may only be opened by a technician.
Danger!
Danger of suffocation!
The room in which the appliance is situated
shall be designed and the appliance installed
within it as specified in BS 6644.

Safety instructions/regulations 3

Installation manual flue pipe for ecoCRAFT 0020058722_024
aCaution!
Risk of corrosion in the flue gas installation!
The combustion air fed to the unit must be free
of chemicals which contain, e.g. fluorine, chlo-
rine or sulphur. Sprays, release or cleaning
agents, paints and adhesives can contain such
materials which can, in certain circumstances,
lead to corrosion when operating the unit, in-
cluding the exhaust gas installation. The ex-
haust ducting may only be installed using the
corresponding parts from Vaillant.
Caution!
Electronic damage and danger of fire by
lightning strike!
If the building is equipped with a lightning con-
ductor system, the flue pipes must be incorpo-
rated in the lightning protection system. The
vertical ducting must be incorporated in the po-
tential balancing system if it contains metallic
components.
Caution!
Malfunction of the unit by obstruction of the
flue gas flow!
Make sure that, during the installation process,
no swarf, mortar remnants etc. are left in the
flue pipes.
Caution!
Malfunctions and water condensate escape as a
result of leaks in the exhaust gas route!
The gaskets are sensitive to mineral oil based
greases. They must therefore not be greased.
Only use water to facilitate the assembly, if re-
quired.
Caution!
Danger of fire!
Outside the ducting, the exhaust pipe must be
at least 5 cm away from combustible building
components.
3.2 Regulations
For installation of the appliance laws, regulations, tech-
nical rules and standards must be considered and ad-
hered to ensure the safe installation of your appliance.
3.2.1 Regulations (Great Britain and Eire)
Attention shall be made to the regulations, guidelines
and standards in force. In particular reference shall be
given to the following regulations, guidelines, standards

4 Tested and approved air/flue
pipes - room-sealed
This chapter describes the peripheral conditions under
which the ecoCRAFT condensing gas boilers can be fit-
ted to flue pipes supplied by the manufacturers shown
in Table 4.1.
4.1 Description
- with flue pipes checked and approved for the gas con-
densing boiler
- room-sealed operation
4.2 Tested and approved air/flue pipes
The exhaust gas systems used must be clearly and un-
ambiguously identifiable and must be in agreement with
one of the certificate numbers given in Table 4.1.
The layout and installation of the flue pipes must be in
accordance with the specification and installation manu-
als provided by the manufacturer of the exhaust gas
system. When the exhaust gas system is completely in-
stalled it must be marked with the prescribed identifica-
tion plate.

Installation manual flue pipe for ecoCRAFT 0020058722_026
The following describes the four possibilities for flue
pipes:
- flue pipes for room sealed operation, combustion air
from the duct
- flue pipes for room sealed operation, combustion air
through the external wall
- flue pipes for room sealed operation, combustion air
and flue gas dispersal above the roof
- flue pipes for room sealed operation, combustion air
through the external wall, flue gas pipe on the facade
aCaution!
Observe the maximum pipe lengths given in the
individual sections. Pipe lengths which are too
long will lead to operational malfunction of the
condensing boiler.
Caution!
Note whether an increased heat transmission
resistance of the exhaust gas pipe is required
by running through the cold section. Otherwise
it may cause the formation of ice in the ex-
haust pipe at low temperatures.
Caution!
The air supply must be installed in such a way
that no rainwater can enter the boiler. Rainwa-
ter ingress can cause a short-circuit of electri-
cal components and can cause corrosion in the
unit.
Caution!
Danger of fire!
Outside the ducting, the exhaust pipe must be
at least 5 cm away from combustible building
components. This does not apply to exhaust
gas pipes which permit less separation distance
in accordance with their classification.
Caution!
The distance between the flue terminal and the
roof must be at least 1 m, to avoid combustion
problems caused by wind pressure.
