4.2 Design and sizing information for connection on the flue gas side
Plastic (PPs) balanced flue system (BF) for separate ventilation air and flue gas routing for the Vitodens up to 35 kW
(type C
, according to TRGI '86/96)
53x
The Vitodens may be operated with
separate flue gas/ventilation air supply as
a balanced flue system, subject to the
following flue gas system conditions:
H Connection to a chimney or duct whose
cross-section is too small to provide the
combustion air supply
H Connection to a chimney, which is
unsuitable for providing the
combustion air supply because of
deposits
H Connection to a moisture-resistant
chimney.
The combustion air is then supplied
through a separate ventilation air pipe,
which is routed separately from the flue
pipe.
