Note
The flue gas parameters for single boilers can be used for the flue
system calculation (see Vitodens technical guide).
The pressure drop of the flue gas back draught safety device has
already been taken into account and does not have to be factored
into the calculation.
The maximum operating pressure according to DVGW G 635 is not
taken into account.
