Note
Flue gas parameters for single boilers can be transferred to the flue
system calculation (see technical guide Vitodens).
The pressure drop of the flue gas non-return device has already been
taken into account, and does not have to be drawn upon in the calcu-
lation.
The maximum operating pressure according to DVGW G 635 is not
taken into account.
