Flue pipe lengths – Vitodens 100-W and 111-W
Up to 6 boilers with the same rated heating output can be connected
to one flue system. The flue pipe lengths detailed below are con-
firmed with the relevant CE designations. If you observe these length
specifications you will not need to make a separate flue pipe length
calculation.

2.11 Plastic (PPs) flue pipe for routing through a shaft – open flue operation (type B
according to CEN/TR 1749)
Open flue operation requires a flue pipe as a connection piece
between the Vitodens and the shaft as well as for routing through the
shaft.
Installation only in rooms with a ventilation air aperture with an
open cross-section of at least 150 cm
to CEN/TR 1749).
Note
Install the Vitodens 200-W, from 60 kW, and multi boiler systems in
accordance with the FeuVO [check local fire regulations] in a sepa-
rate installation room with a suitable ventilation air aperture. The
cross-section must be at least 150 cm
for each kW above 50 kW rated heating output. This cross-section
may not be split over more than 2 vents (FeuVO and CEN/TR 1749
– check local fire regulations).
The flue system is connected to the boiler flue connection.
The combustion air is drawn from the installation room via the annu-
lar gap in the boiler flue connection.
For routing through shafts or ducts with longitudinal ventilation which
meet the requirements for domestic chimneys to DIN V 18160-1, or
which have a fire rating of 90 minutes (L90), or a fire rating of 30
minutes (L30) for buildings in categories 1 and 2.
a For installation in Austria, observe the relevant safety reg-
ulations of the ÖVGW-TR Gas (G1) 1985, ÖVGW-TRF (G2),
ÖNORM, ÖVGW, ÖVE and regional regulations.
Prior to installation, the relevant flue gas inspector should check that
the shaft to be used is suitable and approved for this purpose.

Note
The base connecting assembly for multiple connections must be
installed at the interface to the last heat generator. If an additional
heat generator is to be subsequently installed below the already
installed base connecting assembly for multiple connections, move
the connecting assembly accordingly.

These flue pipe lengths are confirmed with the relevant CE designa-
tions. If you observe these length specifications you will not need to
make a separate flue pipe length calculation.
Close off and seal any other connection apertures with appropriate
materials.
This does not apply to any cleaning or inspection apertures that are
provided with chimney cleaning covers and that are identified with an
appropriate test mark.
Check prior to installation whether the shaft runs straight from top to
bottom or if it is offset (check with mirrors).
If the chimney is offset, we recommend installing a flexible flue pipe
(see page 39).
The relevant flue gas inspector should check the flue system for
tightness prior to commissioning (where applicable).
In the case of open flue operation, this can only be done by means
of a pressure test.
Inside the installation room, at least one inspection port must be pro-
vided in the flue system for checking and cleaning as well as for
checking the pressure.
If the flue pipe is inaccessible from the roof, a second inspection port
must be provided in the attic behind the chimney cleaning hatch.
Safeguard the unrestricted draining of the condensate from the flue
into the boiler through an appropriate fall of at least 3°.
The flue system must protrude above the roof line. Observe the roof
protrusion parallel to the roof slope in accordance with the Landes-
FeuVO [check local fire regulations].
Alternative CE designated flue pipes may be used, e.g. if a larger
pipe diameter is required for longer flue lengths. In that case, the
performance verification to EN 13384 should be provided by the rel-
evant flue pipe manufacturer.
