2.1 Designated application
The burner is suitable for continuous operation (only in conjunction with QRI flame
sensor) on heat exchangers to EN 303 and EN 267.
If the burner is not used on combustion chambers to EN 303 and EN 267, a safety
assessment of combustion and flame stability during individual process conditions
and of the shutdown limits of the combustion plant has to be carried out and documented.
The combustion air must be free from aggressive compounds (e.g. Halogens). If the
combustion air in the boiler room is contaminated, increased cleaning and servicing
will be required. In this case ducted air intake is recommended.
The burner should only be used in enclosed rooms.
Improper use could:
endanger the health and safety of the user or third parties,
cause damage to the unit or other material assets.
2.2 Safety measures
Safety relevant fault conditions must be eliminated immediately.
Components, which show increased wear and tear or whose design lifespan is or
will be exceeded prior to the next service should be replaced as a precaution.
2.2.1 Normal operation
All labels on the unit must be kept in a legible condition.
Stipulated settings, service and inspection work should be carried out at regular
intervals.
Only operate the unit with its cover closed.
Do not touch moving parts during operation.
2.2.2 Electrical connection
For work carried out on live components:
Observe the accident prevention instructions DGUV Regulation 3 and adhere to
local directives,
tools in accordance with EN 60900 should be used.

2.3 Alterations to the construction of the equipment
All conversions require written approval from Max Weishaupt GmbH.
No additional components may be fitted, which have not been tested for use
with the equipment.
Use only original Weishaupt replacement parts.
2.4 Noise emission
The noise emissions are determined by the acoustic behaviour of all components
fitted to the combustion system.
Prolonged exposure to high noise levels can lead to loss of hearing. Provide operating personnel with protective equipment.
Noise emissions can further be reduced with a sound attenuator.
2.5 Disposal
Dispose of all materials and components in a safe and environmentally friendly way
at an authorised location. Observe local regulations.

3.3 Function
3.3.1 Air supply
Air dampers
The air dampers regulate the air quantity required for combustion. The combustion
manager controls the air dampers via actuator. At burner shutdown the air dampers
close automatically. At burner shutdown the air dampers close automatically.
Fan wheel
The fan wheel supplies the air from the air intake housing to the combustion head.
Flame tube
The air gap between flame tube and diffuser is adjusted by positioning the flame
tube. This adjusts the mixing pressure and the air quantity required for combustion.

3.3.2 Oil supply
Oil pump
The pump draws the oil through the supply line and carries it under pressure to the
oil nozzle. The pressure regulating valve keeps the oil pressure constant.
Solenoid valves
The solenoid valves open and close the oil supply.
Oil quantity regulator
The oil quantity regulator is driven by the combustion manager via actuator. An oil
metering vee slot in the oil quantity regulator changes the spill back quantity of the
fuel and thus the atomised quantity of the oil at the oil nozzle. The oil quantity regulator has two metering slots. Each metering slot is matched with a specific oil
throughput. The identity code numbers on the shaft of the oil quantity regulator denote the oil throughput range.

greater than 280 kg/h
Maximum oil pressure switch
The maximum oil pressure switch monitors the pressure in the return. If the value
set is exceeded, the burner switches off.
Minimum oil pressure switch (optional)
Depending on the burner application, optional equipment may be required for optimum operation [ch. 12.3].
The minimum oil pressure switch monitors the pump pressure in the supply. If the
preset pressure is not achieved, the combustion manager initiates a lockout.

3 Product description
Sequence of operation
During the pre-purge time all solenoid valves are closed. For burner ignition, the
combustion manager opens the solenoid valves.
The oil quantity regulator is in the open position (ignition position).
Due to the low resistance of the oil quantity regulator in the return only a small
quantity of oil is atomised at the nozzle, the larger quantity flows to the pump return.
If the load increases, the metering slot in the oil quantity regulator is reduces, this
reduces the oil flow in the return and thus increases the oil quantity at the nozzle
outlet.

3.3.3 Electrical components
Combustion Manager
The combustion manager W-FM is the control unit of the burner.
It controls the sequence of operation, monitors the flame and communicates with all
components.
Display and operating unit (ABE)
The ABE is used to display and alter the operational values and parameters of the
combustion manager. It is connected by connection line and can be remove from
the burner.
Burner motor
The burner motor drives the fan wheel and the oil pump.
Without variable speed drive the combustion manager controls a contactor or star
delta switching.
With variable speed drive, a frequency converter is connected upstream.
Ignition unit
The electronic ignition unit creates a spark at the electrode, which ignites the fuel/
air mixture.
Flame sensor
The combustion manager monitors the flame signal via the flame sensor.
If the flame signal becomes too weak, the combustion manager carries out a controlled shutdown.
See installation and operating manual of the Combustion Manager W-FM for flame
signal required.
Limit switch
The limit switch in the housing prevents burner start in the open position.

DANGER
WARNING
Risk of electric shock
Working on the device when voltage is applied can lead to electric shock.
Isolate the device from the power supply prior to starting any work.
Safeguard against accidental restart.
Electric shock caused by frequency converter
It is possible that electrical components continue to carry voltage and cause electric shock even after the voltage supply has been disconnected.
Wait approx. 5 minutes before commencing work.
Electric voltage has dissipated.
The electrical connection must only be carried out by qualified electricians. Observe local regulations.
Connect combustion manager
Use cable entry grommets on the housing.
Connect wiring to wiring diagram enclosed.
Control circuits, which are taken directly via a 16 AB fuse from a 3 phase or
single phase alternating current supply, must only be connected between a phase
conductor and earth potential neutral conductor.
On mains supply, which does not have a neutral, the control voltage must be supplied via an isolating transformer. The pole of the transformer, which is to be used
as the neutral conductor, must be earthed.
Phase L must not be mixed up with the neutral conductor N. Contact protection will
otherwise no longer be given. Malfunctions, which endanger operational safety
could occur.
The cable cross section of the voltage supply must be suitable for the nominal current of the external fuse (maximum 16 AB). All other cable connections must be
suitable for the relevant internal unit fuse (T6.3H).
Earthing and neutral conductor must conform to local regulations.
The following applies for cable length:
all cable lengths maximum 100 m,
use only original Weishaupt parts as Bus line,
install Bus line as line configuration.

12.1 Oil supply
Observe EN 12514-2, DIN 4755, TRÖI and local regulations.
General information relating to the oil supply
Do not use cathode protection system with steel tanks.
With oil temperatures < 5 °C, the separation of paraffin can cause oil lines, oil filters and nozzles to become blocked. Avoid placing oil tanks and pipelines in
areas subject to frost.
The oil supply should be installed in such a way that it is possible to hinge open
the burner.
Fit oil filter in front of pump, maximum mesh aperture 100 μm.
Suction resistance and supply pressure
CAUTION
Pump damage due to excessive suction resistance
A suction resistance greater than 0.4 bar can damage the pump.
Reduce suction resistance – or – install oil supply pump or suction unit, whilst
observing the maximum supply pressure at the oil filter.
The suction resistance depends on:
suction line length and diameter,
pressure loss of oil filter and other components,
lowest oil level in the oil storage tank (max 3.5 m below the oil pump).
Shut off devices at the burner
CAUTION
Damage caused by the shut off device closing too fast
Pressure surges and cavitation can damage the components of the oil supply.
When testing the operation of the limit switches the shut off device must only be
closed until the safety shut off responds.
The shut off device can only be closed completely when the oil pump has shut
off.
The isolating valves operate mechanically in compound and are fitted with a limit
switch, which inhibits burner operation when the isolating valves are closed.
Protect shut off devices in the return line from accidental closure.
The installation of non return valves is not permitted.

12.1.1 Ring main operation
Oil supply via ring main system is recommended for:
large industrial and district heating installations, which are run almost continually,
larger distances,
several burners.
For installation and function drawing for ring main operation, see Technical worksheets.
The installation of a duplex oil pump station as ring main pump is recommended.
Cleaning and service work on the pump or oil filter is then possible during burner
operation.
The supply quantity must be a minimum of one and a half to twice the total firing
rates of all burners supplied by the ring main.
The burners are connected to the ring main via a two pipe system.
Set ring main pressure for fuel oil EL via pressure regulating valve to
1 … 1.5 bar.
The oil filter must be suitable for the ring main pressure.
An oil circulation device or Weishaupt gas/air separator should be fitted at each
oil outlet point. Observe information label on separator.
12.1.2 Oil circulation unit
The ring main supply can be fitted with an oil circulation unit.
The unit contains:
oil meter,
oil filter,
circulation tank,
safety valve.
Recommendation Weishaupt oil circulation unit W-OC-…
12.2 Flue gas system
