Combustion check at full load
Start the boiler in controller stop mode
and go to full load operation (100%).
Now the boiler operates at 50% load.
Allow the boiler to stabilise the
combustion for 3 minutes. Then
increase the boiler load step by step up
to 100%. Check the gas pressure on
the inlet of the gas valve while increa-
sing the boiler load: the gas pressure
should never go below the minimum
required value  see technical data.
Set the minimum gas pressure switch
(1) at 75% of the required gas pressu-
re.
Check the combustion settings via the
test point in the chimney connection(3).
If necessary, correct the settings with
the flat adjustment screw on the outlet
of the gas valve (2).
Combustion check at minimum load
Switch the boiler to minimum load (0%).
Check the combustion settings the
same way as described for full load. If
necessary, correct the settings with the
allen key adjustment screw on either
side of the gas valve (4).
Combustion check at 50% load
An additional reference check of com-
bustion values at 50% load is recom-
mended in order to check if the gas
valve is set in such way, that the modu-
lating behaviour is normal. The CO
value should be in between the settings
of full load and minumum load. CO
value should be equal to full load and
minimum load values.
Make sure that the boiler is set to auto-
matic operation and controller stop mo-
de is disabled after the combustion test
is finished.
