According to the approval certificate, internal shaft dimensions
smaller than those shown in the table may also be used, provided
this is allowed under performance verification to EN 13384.
When connecting 2 condensing boilers to one chimney on the same
floor, the connection piece inlets should be separated by at least
300 mm.
Design and calculations for balanced flue systems with multiple con-
nections are carried out by the relevant manufacturer.
