Balanced Flue Operation With The Vitocrossal 200 - Viessmann VITOCROSSAL 200 Type CM2 Technical Manual

Design information

Balanced flue operation with the Vitocrossal 200

For balanced flue operation, the Vitocrossal 200 requires a flue pipe
between the gas condensing boiler and the shaft as well as for routing
through the shaft (type C to TRGI 2008).
53
System size flue pipe 7 125, 150, 200 and 250 mm.
For routing through shafts or ducts with longitudinal ventilation
that meet the requirements for domestic chimneys to DIN V
18160-1, or have a fire rating of 90 min (L90).

If the ventilation air supply is routed separately, use individual com-
ponents in the corresponding size for flue pipes.
A boiler flue connection must be ordered for the connection to the
Vitocrossal.
