Startup

Burner adjustment

Start burner
Start burner by activating the boiler regulator.
To purge fully the fuel-oil conduit during
the pre-ventilation phase, open the
bleed screw on the fuel-oil filter. Do not
allow negative pressure to drop below
0.4 bar during this operation. When
fuel-oil begins to flow without bubbles,
and the filter is completely filled with
fuel-oil, shut the bleed screw.
Setting stage 1 (cam IV)
· Pull out 4P-plug, burner moves to
stage 1.
· Use pressure regulator 8 to adjust
the fuel-oil pressure for stage 1
according to the desired burner
power. Carry out constant checks on
the combustion air (CO, CO
soot-test) while doing so. Change the
air quantity if necessary, carrying out
adjustment in small steps.
· To increase the air quantity: move
cam IV to a higher setting on the
scale.
· Unplug and immediately reconnect
the 4P-plug. The air-flap motor
adopts the new minimum-load
position.
· To reduce the air quantity: set cam IV
to a lower scale value, servomotor
adapts position automatically.
Optimise combustion values
Optimise combustion values if
necessary by adjusting the position of
the turbulator (dimension Y).
This can be used to influence starting
performance, pulsations and
combustion values.
Reduction of scale value Y increases
the CO value, making starting
2
conditions harder.
Adapt the airflow quantity, if necessary,
by adjusting the air flap setting.
m
Beware of fuel-oil spurting out !
Carry out constant checks for CO,
CO and soot emissions during the
2
adjustment operation. In the event of
build-ups of CO and/or soot,
optimise the combustion settings.
The proportion of CO must not
exceed 50ppm. Soot-count < 1.
Setting stage 2 (cam I)
· Switch to stage 2 at 4P-plug.
· Use pressure regulator 9 to adjust
the fuel-oil pressure for stage 2
according to the desired burner
power. Carry out constant checks on
the combustion air (CO, CO
, soot-test) while doing so. Change the
2
air quantity if necessary, carrying out
adjustment in small steps.
· To increase the air quantity: Set cam
I to a higher scale value, servomotor
adapts position automatically.
· To reduce the air quantity: move cam
I to a lower setting on the scale.
· Unplug and immediately reconnect
the 4P-plug.
· Air flap moves to the newly-adjusted
position.
IMPORTANT: Observe the minimum
required flue-gas temperature, as
per the indications of the boiler
manufacturer, and according to the
requirements of the exhaust gas
conduits, in order to prevent
condensation forming.
If dimension Y needs to be corrected
again when adjusting stage 1, check
the settings of stage 2.

Setting switchover point, solenoid
valve stage 2 (cam III)
· Switch over burner several times
from stage 1 to stage 2. Adjust cam
III in such a way that there is a
smooth changeover from stage 1 to
stage 2.
