Values for calculating the size of the flue system to EN 13384, based on 10 % CO
*1
Flue gas temperatures as actual gross values at 20 °C combustion air temperature.
The details for partial load are based on the following output: 20 % of the rated heating output for natural gas and 25 % of
the rated heating output for LPG. If the partial load differs (subject to burner operating mode), calculate the flue gas mass
flow rate accordingly.
*2 If using the Vitocrossal 200 with moisture-resistant chimneys, the draught must be no more than 0 Pa.
*3 Standard values resulting from sound pressure level testing cannot be guaranteed, as sound pressure level tests are al-
ways dependent on the specific system.
*4 The connection values are only for documentation purposes (e.g. in the gas contract application) or to estimate a supple-
mentary volumetric check of the settings.
Due to factory settings, the gas pressure must not be altered from these values. Reference: 15 °C, 1013 mbar/101.3 kPa
