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.
m
Beware of fuel-oil spurting out !
Carry out constant checks for CO,
CO
2
and soot emissions during the
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-index
<
1.
Setting stage 1 (cam IV)
·
Move burner to stage 1.
·
The oil pressure is set via screw
6.1
(on L 04.410 DUO) and
6
(on
L 04.500 DUO) according to the
burner performance required. The
combustion settings must be checked
continuously here (CO, CO
2
, smoke
emission test). Where necessary,
adjust the air quantity, or adjust in
increments where required.
·
To increase the air quantity: move
cam
IV
to a higher setting on the
scale.
·
Move burner shortly to 2
d
stage and
immediately return to 1
st
stage. 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
2
value, making starting
conditions harder.
Adapt the airflow quantity, if necessary,
by adjusting the air flap setting.
Setting stage 2 (cam I)
·
Switch to stage 2 at 4P-plug.
·
The oil pressure is set via screw
6.2
(on L 04.410 DUO) and
6
(on
L 04.500 DUO) according to the
burner performance required. The
combustion settings must be checked
continuously here (CO, CO
2
, smoke
emission test). Where necessary,
adjust the air quantity, or adjust in
increments where required.
·
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.
·
Move burner shortly to 1
st
stage and
immediately return to 2
d
stage.
·
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.
