Emission measurement

6 Emission measurement
Why measure emissions?
It is a requirement for the carbon monoxide (CO)
emissions of every boiler to be measured periodically.
In Germany, this periodic measurement must also
include a dust measurement.
There are several aspects of this that could go wrong,
resulting in incorrect measurements even though the
boiler fully and consistently complies with these limits
when operating in accordance with the relevant
standards.
Notes on emission measurement in Germany
In accordance with the provisions of "BImSchV,"
lower limit values for the emission measurement
in Germany apply to all new heating system installa-
tions starting 1 January 2015. Notes on compliance
are found under
7 "Low-emission operation" .
Clean the boiler 3 - 5 days before the emission
measurement
Thoroughly clean the boiler and flue pipe 3 - 5 days
before the emission measurement. Once this is
complete, heating can resume as usual.
This delay between cleaning and measurement
is necessary in order to allow dust disturbed
during cleaning to settle again. If the chimney sweep
measures unsettled dust, the dust reading will be
higher than normal and thus inaccurate.
CAUTION!

Under no circumstances clean the boiler and flue
pipe on the day of the measurement!
Ensure sufficient heat consumption
Open all radiator valves and turn radiator thermostats
to maximum.
Selecting emission measurement for full load or
partial load
National regulations may stipulate emission
measurement at partial load. If this is the case, you
must set the required output range before
commencing the emission measurement.
With access level [Service] go to the text menu of the
boiler. You can adjust the output range as follows:
If [Combination] is selected, first the measure-
ments for full load are performed. After expiry of
the selected duration ([MeasDuration]), a message will
appear that states that the measurement for the partial
load can now be performed.
Setting the duration of the emission measurement
The duration of the emission measurement is
factory-set to 45 minutes. If necessary, this can
be increased with the [Service] access level. To do so,
switch to the text menu of the boiler. You can adjust the
duration as follows:
Prepare and perform emissions measurement
1. The boiler must be switched on with the On/Off
switch. In the boiler overview, press the
[Measurement] button in order to open the
emissions measurement settings window.

2. Use the [Begin measurement] button to enter
the date agreed for chimney sweeping. The boiler
will then start in time to reach the permissible
operating temperature for measurement purposes.
By pressing the [Start now]
button, the boiler
will immediately begin preparations for a
subsequent measurement.
In addition, the locking time of the boiler can be
adjusted (
[Lock duration] button). This relates
to the set time of the measurement. During this
period no heating operation will be started, so that
the heating system has time to cool down.
