4.2 Design and sizing information for connection on the flue gas side
Plastic (PPs) balanced flue system (BF) for routing multiple pipes through an air/flue gas chimney
The Vitodens condensing boiler meets
the safety requirements in accordance
with DIN 3368 6.
Therefore, a general Building Regulations
approval for connection to a LAS system
is not required.
When connecting two condensing boilers
to one chimney on the same floor, the
union inlets should be separated by at
least 300 mm.
Design and calculations for LAS chimney
systems with multiple ducts are carried
out either by the respective supplier or by
the Viessmann customer service.
