5.9.1 Flue gas pipe: Hole for emission mea-
surement
►
Make the hole for the emission measurement
according to the following images (recom-
mendation according to standard).
►
If these specifications cannot be implemented,
then make the measuring point after a calming
section, i.e. after the longest straight section of
the pipe. The tube orientation (horizontal, ver-
tical, oblique) plays no role in this case.
►
In any case, place the measuring point before
any existing draught limiters.
You can find the function for carrying out the emission
measurement in the boiler operation manual,
