Values for calculating the size of the flue system to EN 13384, based on 10 % CO

for natural gas
Flue gas temperatures as actual gross values at 20 °C combustion air temperature.
The details for partial load refer to an output of 30 % of the rated heating output. If the partial load differs (subject to burner
operating mode), calculate the flue gas mass flow rate accordingly.
