Installation manual Air/flue gas system 0020058722_04
Technical feature Description
Leaks Adapted to the product for use
in buildings and outdoors
Condensate resistance For gas and oil fuels
Corrosion resistance Adapted to the gas and oil
condensing boiler
Clearance from combustible
materials Not necessary
Installation location In accordance with the install-
ation instructions
Resistance to fire Normal level of flame resist-
ance (in accordance with EN
13501-1 Class E)
Fire resistance time None:
The external pipes of the
concentric system are not
flammable. A required fire
resistance time is provided by
shafts within the building.
5.2.2 Requirements for the shaft for the flue pipe
Flue pipes from Vaillant do not have any fire resistance (dir-
ection of operation from the outside to the inside).
If the flue pipe is guided through parts of a building that re-
quire a level of fire resistance, a shaft must be fitted. The
shaft must ensure the fire resistance (direction of operation
from the outside to the inside) that is required for the building
parts through which the flue gas installation is guided. The
required fire resistance must demonstrate a suitable classi-
fication (brick partition and heat insulation) and be sufficient
for the building's requirements.
Observe the national ordinances, regulations and standards.
An existing chimney that was used for the flue gas guiding
usually meets these requirements and can be used as a
shaft for the flue pipe.
The gas tightness of the shaft must comply with the test
pressure class N2 in accordance with EN 1443. An exist-
ing chimney that was used for the flue gas guiding usually
meets these requirements and can be used as a shaft for the
air guiding.
If the shaft is used to supply combustion air, this must be
designed and, in particular, insulated in such a way that no
moisture (caused by the cooling of the shaft by cold combus-
tion air penetrating from the outside) can penetrate the ex-
terior of the shaft. An existing chimney that was used for the
flue gas guiding usually meets these requirements and can
be used as a shaft for the supply of combustion air without
the need for additional heat insulation.
5.2.3 Route of the flue pipe in buildings
The route of the flue pipe should correspond to the shortest
and the most direct distance between the product and the
flue gas installation opening, and it should run as straight as
possible.
▶ Do not arrange several diversions immediately after each
other.
As a result of standards relating to the hygiene of drinking
water, water pipes must be protected against impermissible
heating.
▶
Lay the flue pipe separately from the drinking water
pipes.
It must be possible to check and, if required, clean the entire
length of the flue gas route.
It must be possible to remove the flue pipe again with a min-
imal amount of effort (no time-consuming mortising work in
the living area, but screwed-in cladding instead). If they are
arranged in shafts, they are usually easy to remove.
5.2.4 Location of the opening
The location of the flue gas installation opening must comply
with the relevant applicable international, national and/or
local regulations.
▶
Align the opening of the flue gas installation in such a
way that ensures a secure outward flow and distribution
of the flue gases and prevents these gases from re-en-
tering the building through openings (windows, air intake
openings and balconies).
5.2.5 Disposing of condensate
Local regulations may stipulate the minimum quality of any
condensate that may enter the public waste-water system. If
required, a condensate neutraliser must be used.
▶ When disposing of the condensate into the public waste-
water system, observe the local regulations.
▶
Only use corrosion-resistant piping material for removing
condensate.
6 Installing the 130 mm diameter
system
To install the 130 mm diameter shaft system, the flue gas
pipe is installed in the shaft first. The flue gas connection and
the horizontal flue gas pipe are then installed and, finally, the
combustion air line is installed.
6.1 Installation instructions
▶ For inspection purposes, install at least one inspection T-
piece in the flue gas pipe in the boiler installation room.
▶
You must not immure the flue pipe.
▶
Use the safety pipe contained in the scope of delivery for
the shaft opening.
The shaft dimensions for installing the basic set must be at
least:
–
170 mm x 170 mm
–
190 mm diameter
