Plastic (Pps) Flue Gas/Ventilation Air System For Separate Ventilation Air And Flue Gas Routing; To Tröi 2009) - Viessmann Vitoladens 300-C Technical Manual

Design and sizing information for the Vitoladens 300-W and 333-F
3.3 Plastic (PPs) flue gas/ventilation air system for separate ventilation air and flue gas
routing (type C to TRÖI 2009)
83x
The Vitoladens may be operated with separately routed flue gas and
ventilation air in balanced flue mode, subject to the flue system meet-
ing the following conditions:
■ Connection to a chimney that is unsuitable for providing the com-
bustion air supply because of deposits.
■ Connection to a moisture-resistant chimney.
The combustion air is then supplied through a separate ventilation air
pipe that is routed separately from the flue pipe.
Observe the design information to TRÖI 2009, point 5.6.
Internal flue diameter: Ø 60 or 80 mm
Internal diameter, external pipe: Ø 100 or 125 mm
Internal diameter, ventilation air pipe: Ø 125 mm
Max. pipe length:
■ Connection piece: 3 m
■ Ventilation air pipe: 4 m

Note
Where the flue pipe is routed through an existing chimney or shaft (not
moisture-resistant), use flue pipe components according to page 26.

Max. number of bends (flue pipe and ventilation air pipe):
■ 87º: 2 pce each
or
■ 45º: 3 pce each
Install an inspection port for checking and cleaning the flue pipe.
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.
The flue system for separate ventilation air and flue gas routing has
been tested as a single technical unit with the Vitoladens condensing
boiler.
A performance verification according to EN 13384 for the ventilation
air side and the connection pieces is not required.

The following components are taken into consideration for the maxi-
mum flue lengths:
■ Connection pipe D 0.5 m long.
■ 1 bend 87º and 1 support bend 87º
or
■ 2 bends 45º and 1 support bend 87º
Subtract other bends, tees and extension pieces from the maximum
length using the following values:
■ Connection pipe 0.5 m long: 0.5 m
■ Connection pipe 1 m long: 1 m
■ Bend 45º: 0.3 m
■ Bend 87º: 0.5 m
■ Inspection tee: 0.3 m
