19
Commissioning, inspection, maintenance
Further details regarding the individual steps (cont.)
The flue pipe is deemed to be gastight if the CO 2 concentration in the
combustion air is no higher than 0.2 %
or the O 2 concentration is at least
20.6 %.
If actual CO 2 values are higher or O 2
values are lower, then pressure test
the flue pipe with a static pressure of
200 Pa.
5692 682 GB
For balanced flue systems tested
together with the wall mounted gas
fired boiler, the requirement for a
tightness test during commissioning
by the flue gas inspector is not applicable.
We recommend that your heating
engineer carries out a simple leak/
tightness test during the commissioning of your system. For this, it would
be sufficient to check the CO 2 or O 2
concentration in the combustion air at
the annular gap of the balanced flue
pipe.

Checking the combustion quality
The electronic combustion control unit automatically ensures an optimum combustion quality. Only the combustion values need to be checked during commissioning and maintenance. For this, check the CO 2 or O 2 content. For a function
description of the electronic combustion control unit, see page 115.
CO 2 or O 2 content
& The CO 2 content must be within the following ranges (upper and lower output):
– – 7.7 to 9.2% for natural gas E and LL
– – 9.3 to 10.9% for LPG P
& For all gas types, the O 2 content must be between 4.4% and 6.9%.
If the actual CO 2 or O 2 values lie outside their respective ranges, proceed
with the following steps:
& Check the balanced flue system for tightness, see page 19.
& Check the ionisation electrode and connecting cable, see page 23.
& Check the parameters of the combustion control unit, see page 97.
Note
During commissioning, the combustion control unit carries out an automatic
calibration. This may lead to CO emissions in excess of 1000 ppm for a short
time.
1. Connect a flue gas analyser at flue
gas port A on the boiler flue connection.
2. Open the gas shut-off valve, start
the boiler and create a heat
demand.

Then standard control mode
resumes.
2. Note the rotational direction of the
mixer motor during its self-test.
Then set the mixer manually to
"Open" again.

Electronic combustion control unit
To check the combustion quality, the
CO 2 content or the O 2 content of the
flue gas is measured. The actual
values enable the prevailing air factor
to be determined. The relationship
between the CO 2 or O 2 content and
air factor λ is illustrated in the following table.
5692 682 GB
The electronic combustion controller
utilises the physical correlation
between the level of the ionisation
current and the air factor λ. For all gas
qualities, the maximum ionisation current results with air factor 1.
The ionisation signal is evaluated by
the combustion control unit, and the
air factor is adjusted to between
λ=1.24 and 1.44. This range provides
for an optimum combustion quality.
Thereafter, the electronic gas valve
regulates the required gas volume
subject to the prevailing gas quality.

The combustion control unit can also

5692 682 GB
To achieve an optimum combustion
control, the system regularly carries
out an automatic self-calibration; also
after a power failure (shutdown). For
this, the combustion is briefly regulated to max. ionisation current
(equals air factor λ=1). The automatic
calibration is carried out shortly after
the burner start and lasts approx. 5 s.
During the calibration, higher than
normal CO emissions may occur
briefly.
