Plastic (Pps) Flue/Ventilation Air System For Separate Ventilation Air And Flue Gas Routing (Type C To Trgi 2008) - Viessmann VITODENS Technical Manual

Design and sizing information for connection on the flue gas side
2.5 Plastic (PPs) flue/ventilation air system for separate ventilation air and flue gas routing
(type C to TRGI 2008)
83x
The Vitodens may be operated in balanced flue mode and with sep-
arately routed flue gas and ventilation air, subject to the flue system
meeting 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 according to TRGI 2008.
Internal diameter, flue pipe: Ø 60 or 80 mm
Internal diameter, external pipe: Ø 100 or 125 mm
Internal diameter, ventilation air pipe: Ø 100 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 the flue pipe components according to
page 14.

Max. number of bends (flue pipe and ventilation air pipe):
■ 87°: 2 pce each
or
■ 45°: 3 pce each
Install an inspection port in the flue for checking and cleaning the flue
pipe. Safeguard the draining of the condensate from the flue into the
boiler by maintaining an appropriate fall of at least 3°.
As part of the CE approval test it was verified that no surface temper-
atures on the Vitodens 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 structural unit with the Vitodens condensing
boiler.
A performance verification according to EN 13384 for the ventilation
air side and the connection pieces is not required.
