Design and sizing information for the Vitoladens 300-W and 333-F

3.4 Plastic (PPs) balanced flue system for vertical routing through a pitched or flat roof

(type C to TRÖI 2009)
33x

For vertical roof outlet

Use the vertical roof outlet only in single storey buildings.
If the balanced flue system is routed through roof spaces that are not
used as accommodation, run the balanced flue pipe through an addi-
tional metal pipe as protection against mechanical damage (TRÖI
2009, point 5.6.1.2).
It may also be routed behind a jamb wall or a solid wall of a converted
attic, if the fire protection class of the jamb wall corresponds to that of
the ceiling (e.g. B30).
Minimum clearances to combustible materials inside the installation
room or around the roof outlet are not required.
As part of the CE approval test, it was verified that no surface temper-
atures on the Vitoladens or its balanced flue system will exceed
85 °C.

Integrate the flat roof collar into the roof skin according to the flat roof
guidelines (see page 49). Push the roof outlet into the roof from
above and position it on the flat roof collar.
Note
The ceiling opening should have a diameter of at least 130 mm.
Secure the roof outlet on site with a clamp only after the installation
has been completed.

Internal flue diameter: Ø 60 or 80 mm
Internal diameter, ventilation air pipe: Ø 100 or 125 mm
Max. number of 45° bends: 2 pce
If the number of bends differs, for each 45° bend, deduct or add
0.3 m from/to the maximum extended pipe length.
Install an inspection port for checking and cleaning the flue pipe inside
the installation room.
The vertical roof outlet has been tested as a concentric balanced flue
system as a single technical unit with the Vitoladens condensing
boiler.
A performance verification according to EN 13384 is not required.
If installing several vertical roof outlets adjacent to each other, maintain
minimum clearances of 1.5 m between each outlet and from other
components in accordance with local regulations.
