4.2 Design and sizing information for connection on the flue gas side
Plastic (PPs) balanced flue system for external wall terminal
(type C , according to TRGI '86/96)
13x
Note
The external flue terminal is only
compatible with existing building
standards, if another flue gas route is
inappropriate on technical or economical
grounds.
According to TRGI '86/96, item 5.6.1.1, the
external wall terminal is only permissible
for boilers with rated output up to 11 kW
(central heating) or 28 kW (DHW heating).
The conversion to 11 kW central heating
should be documented by the heating
engineer carrying out the conversion on
an additional type plate.
It was verified as part of the CE approval
test that nowhere on the Vitodens or the
balanced flue system surface will
temperatures higher than 85 ºC occur.
