The details apply subject to the following assumptions:
■ Length of the connection piece (flue): 2 m and 3 x 87° bends (includ-
ing support bends)
■ Length of the connection piece (ventilation air line): 2.5 m and 2 x
87° bends
Note
11
With the Vitocrossal 200 with MatriX radiant burner, a draught of 70
30
Pa is available for the balanced flue system.

Minimum distance for secondary ventilation between the internal
11
cross-section of the shaft and the female connection, see page 31.
30
For balanced flue operation, the Vitocrossal 200 requires a flue pipe
10
between the gas condensing boiler and the shaft (chimney) (type C
30
to TRGI 2008).

System size flue pipe 7 125, 150, 200 and 250 mm.
30
If the ventilation air supply is routed separately, use individual com-
ponents of the flue pipe size 7 150 or 200 mm.
30
A boiler flue connection must be ordered for the connection to the
15
Vitocrossal.
