themselves or specialists authorized by
them. Original parts should only be
exchanged by a duly qualified specia-
list.
Standards and regulations
The following standards should be
observed in the interest of a safe, easy-
on-the-environment and energy-saving
operation of the burner:
According to DIN 4755, the user must
be instructed in the operation of the bur-
ner.

system, care should be taken to
observe DIN 4755, TRbF (Technical
Regulation onCombustible Liquids) and
the local furnace construction regulati-
ons applicable in the country.
Place of installation
The burner must not be operated in
rooms containing aggressive vapours
(e.g. spray, perchloroethylene, hydro-
carbon tetrachloride, solvent, etc.) or
tending to heavy dust formation or high
air humidity.
Adequate ventilation must be provided
at the place of installation of the furnace
system to ensure a reliable supply with
combustion air.
Maintenance
The furnace system should be serviced
at least once a year by an authorized
specialist. It is recommended to con-
clude a maintenance agreement to this
effect.
Warranty
Manufacturer will not accept any war-
ranty if the operating instructions have
not been duly observed in the start-up
and maintenance of the burner and
damages have been caused by impro-
per installation, incorrect adjustment,
unauthorized interference or operating
errors.

Operation
Start-up Mode
Oil Operating Mode
General Safety Functions
Start-up mode
As soon as the furnace system is requi-
red to supply heat the burner control cir-
cuit will close and the program be
started. Afterthe programhas run down
the burner will start.
The air damper is closed when the
burner is out of operation.
The automatic furnace controller con-
trols and monitors the starting function.
The electric actuator opens the closed
air damper to its full-load position so
that the burner will sweep the furnace
compartment and exhaust ports at the
required air flow rates. Shortly after the
pre-ventilationprocesshasbeen started
the lack-of-air cut-out must change over
to operating position within a certain
time, i.e. the minimum air pressure set-
ting must be reached and maintained
until the burner is turned off. At the end
of the specified pre-ventilation time the
air damper will be moved into its partial-
load position. This operation will be fol-
lowed by the pre-ignition procedure and
the oil feed start.
The solenoid valves will open and thus
allow the pressurized oil to flow to the
nozzle and to the return line. The oil will
be atomized, mixed with the combustion
air and ignited.
A safety period is provided to allow the
flame to develop a proper and steady
pattern. On the termination of the safety
period, a flame signal must have been
received by the automatic furnace con-
troller via the flame monitor and remain
on until the regular shut-off. Thestart-up
program of the burner has now been
completed.
Oil operating mode
After the flame has developed the load
regulator will be enabled which brings
the burner into its operating position.
The load regulator will now control the
burner automatically between its partial-
load and full-load stages.
Depending on the heat rate required the
servomotor will via the controller be
given an "open" or "close" signal and
thus increase or decrease the oil and air
flow rates.
This compound control concept will vary
the position of the oil control valve and
air damper and thus adjust the oil flow
rate in relation to the air flow rate.
The stepless control will allow the bur-
ner to be operated at any desired stage
between its partial-load and full-load
positions. The burner will be turned off
from its partial-load position. The air
damper will be closed when the burner
is out of operation and will thus prevent
cold air flowing through the burner
chamber, heat exchanger and chimney.
The interior cooling losses will be grea-
tly minimized.
General safety functions
In case a flame does not develop when
starting the burner (fuel release) the
burner will shut off at the end of the
safety period (shut-off on trouble). A
shut-off on trouble will also occur in the
case of flame failure during operation,
air flow failure during the pre-ventilation
phase and pressure failure during the
whole period of burner operation. Any
failure of the flame signal at the end of
the safety period and a flame signal
during the pre-ventilation phase (exter-
nal light control) will result in a shut-off
on trouble with the automatic furnace
controller being locked. The trouble is
indicated by the trouble signal lamp
lighting up. The automatic furnace con-
troller can be unlocked immediately
after a shut-off on trouble by pressing
the unlocking key. The program unit will
return to its starting position and pro-
ceed with the restart of the burner.
A voltage failure will result in a regular
shut-off of the burner. Upon voltage
recovery there may be an automatic
restart unless another interlock is provi-
ded, e.g. by the safety system. In any
case of trouble the fuel oil supply will be
shut off right away. The program unit
will stop at the same time causing also
the trouble location indicator to stop.
The symbols will indicate the kind of
trouble.
When using the burner control system
type BCS all operational and fault mes-
sages may be indicated in plain text on
an optionally available operating and
display module.

Operation
Fuel-air Compound Control
Hydraulic Diagram
Fuel-air compound control
This compound pneumatic control
system with precision-adjustment capa-
bility has been designed to allow the
fuel and air flow rates to be steadily
varied in sliding mode for an adjustment
of the fuel-air ratio over the whole con-
trol range.
In the two-stage sliding control concept
the partial-load and full-load positions
are within the control range. Depending
on the heat demand these two load
points will be selected in sliding mode.
A larger fuel feed will not be suddenly
turned on or off. In the stepless control
mode the load will be controlled at any
point within the control range depending
on the heat demand. The two-stage sli-
ding and the stepless control concepts
are different only in the control systems
used with the burners. The same mode
of operation is used for both versions.
Electronic compound control:
The air box includes an actuator for
operating the airdamper. The oil control
valve incorporates an actuator for adju-
sting the return oil flow rate and thus the
output of the burner.
The actuators for the air and fuel flow
control will be operated depending on
output by the electronic compound con-
trol which will move them into the pro-
grammed positions.

Operation
Hydraulic Valves and Instruments Group
The hydraulic valves and instruments
group is an integrated concept that
combines several functions of the
hydraulic systems of burners. Its modu-
lar construction makes it possible to
meet a wide range of requirements and
conditions of installation. The pump
adapter module (1) allows the hydraulic
valves and instruments group to be
mounted directly to oil burner pumps of
any size. It is fastened to the pump by
means of hollow bolts which are provi-
ded with ¼" screw plugs (4) for venting
the pump when taken into operation.
The basic group module (2) is moun-
ted to the pump adapter with the two
modules being sealed against each
other by O-rings in the supply and
return pipes. Depending on the level of
equipment of the hydraulic system, oil
pressure switches and pressure gauges
may be installed in the supply and
return pipes of the basic module. The
solenoid valve in the supply pipe is of
servo-assisted type while the return
valve is directly controlled. The soleno-
ids of the two valves are electrically
connected in series which will prevent
one of the valves being opened alone if
any of the solenoids is defective. For
the replacement of the solenoid valves
during maintenance work it should be
ensured that the right valve type is
installed in the correct direction of
mounting. For mounting the solenoid
valve in the supply pipe (type 321 H
2520) it must be ensured that the direc-
tion of flow shown be a stamped arrow
on the valve flange is the same as the
direction of flow of the oil (from the
pump to the nozzle rod). The solenoid
valve in the return pipe (type 121 G
2520) is marked with a stamped arrow
opposite to the direction of the oil flow
from the nozzle rod back to the pump.
The volume flow control valve installed
in the return pipe consists of a bush
pressed into the hydraulic valves and
instruments group and locked against
torsion and a control shaft. As the con-
trol shaft is turned, the contoured confi-
guration of the bush and shaft will
change the open cross section for the
oil flowing back and thus vary the oil
return flow rate. Control shafts with dif-
ferent control contour parameters are
available for adjustment to various oil
nozzle sizes. This concept ensures that
an excellent control characteristic and a
wide control range can be covered for a
great variety of applications. The control
contour parameter is affixed to the con-
trol shaft by means of an electric mar-
ker. The current position of the control
shaft is indicated by the position display.
From the "min." mark (low load of bur-
ner) the control shaft will turn clockwise
to the "max." mark (full load of burner).
If the control shaft has been removed
during maintenance work care should
be taken when reinstalling it to ensure
the right mounting position of the control
contour by observing the centre punch
mark on the shaft end face. In the low
load position (min.) the centre punch
mark will in any case point up (12
o'clock position - see figure).
If the hydraulic valves and instruments
group is used in conjunction with nozzle
rods not approved as safety shut-off
valve according to EN 264, an exten-
sion module (3) is available which
incorporates an additional solenoid
valve each in the supply and return
pipes. The extension module is atta-
ched directly to the basic module. The
modules are sealed against each other
by O-rings.
Metal hoses are used for connection
between the hydraulic valves and
instruments group and the nozzle rod.
The hose lines must be protected
against exterior mechanical damage.
The hoses must be positioned and
mounted in accordance with the appli-
cable technical standards. For the
installation care must be taken not to
introduce torsional or buckling stresses
neither by the mounting procedure nor
by movements at a later stage. Speci-
fied bending radii of the hoses must not
be changed.

Burner mounting
For mounting the burner to the boiler
make sure the connection plate has
been prepared according to the dimen-
sions given in the technical datasheets.
• Install the stud bolts in the connection
plate.
• Put the insulating backing and burner
in place and fasten by bolts.
Check before burner installation
1. Select the nozzle according to
boiler output and combustion
chamber geometry.
2. Set the mixing and ignition unit
according to the boiler output.
For the standard factory setting
refer to the burner head settings.
3. Set the ignition electrodes on the
nozzle.
4. Check the burner tube installation
depth according to the data speci-
fied by the burner and boiler
manufacturers.
Electrical connection
The electrical connection work compri-
sing all the installation materials, termi-
nals and earth connections must be
carried out in accordance with the appli-
cable regulations. For the electrical
installation of the burner care must be
taken to observe the circuit diagram
made out for the furnace system.
The electrical connection of the burner
and gas valves and instruments shall be
entrusted to authorized specialists only.
NOTE: For the installation of the con-
nection cables care must be taken to
provide cable loops of sufficient length
to allow for the swing-out of the boiler
door and burner.
Make sure after the completion of the
electrical connection work to check the
wiring of the electrical system of the
burner. This should include a check of
the direction of rotation of the burner
motor (fan).
Boiler inspection glass cooling
For cooling and cleaning the boiler
inspection glass a cooling line (e.g.
hose) may be installed from the burner
to the inspection glass. The burner is
provided with a connection socket for
this purpose.
