misprints or typographical errors.
Modifying the design or using accessories or components that have not been
approved by Enertech in writing is strictly prohibited.
This Installation and Maintenance manual:
• is to be regarded as part of the burner and must always be kept near
the installation site.
• must be read prior to installation.
• is intended for use by authorised personnel.
1.1 Delivery inspection
• Make sure everything is delivered and the goods have not been
damaged during transit.
Transport damage must be reported to the shipping company.

1.2 Safety
- before installation:
• Installation and work on the burner and associated system
components may only be carried out by persons who have undergone
relevant training.
• The product is packaged to prevent damage from occurring when
handled – Handle the product with care! Lifting equipment must be
used to lift larger packages.
• The products must be transported/stored on a level surface in a dry
environment, max. 80% relative humidity, no condensation.
Temperature -20 to +60 °C.
- installation:
• The burner must be installed in accordance with local regulations for
 re safety, electrical safety, and fuel distribution.
• The premises must comply with local regulations pertaining to use of
the burner, and must have adequate air supply.
• The installation site must be free of chemicals.

• The burner must not be put into operation without proper safety and
protection devices.
• Permitted ambient temperature during operation -10 to +60 °C. Max.
80% relative humidity, no condensation.
• The surface temperature of the burner’s components may exceed
60 °C.
• Handle with caution – the burner has moving parts, and there is risk
of crushing injuries.
• Seal inspections must be performed during installation and servicing
to prevent leakage.
•  tting and installation work has been completed and approved.
• electrical installation has been correctly performed.
•  ue gas ducts and combustion air ducts are not blocked.
• all actuators and control and safety devices are in working order and
correctly set.
• If the boiler is equipped with an access hatch, this must be equipped
with a hatch opening switch connected to the burner’s safety system.
• When in operation, the burner’s noise level can exceed 85 dBA – use
hearing protection!
- Operation:
• Carry out all stipulated settings, service and inspection work within
the set time.
• If the oil burner control has a solid red light, contact your installer.

2.6 Setting of ignition electrodes and brake
plate
Measurements according to EN 15036-1:2006
Alt.1 The noise level of the burner can be reduced by equipping the burner with
silencer. Installation must be done so it does not prevent air supply to the
burner.
Alt.2 The burner’s noise level can be reduced by connecting the burner’s air
intake to the air duct that opens into an appropriate location. Installation
must be done so it does not prevent air supply to the burner.
!*NB It is important that the spark
does not strike against the brake
plate or nozzle.
Nozzle: 45° Solid/semisolid
60° Solid/semisolid
80° Solid/semisolid
Pump pressure: 14 bar (14-21 bar) depending on pump model

The safety system (safety switch for hatches, doors, water level, pressure,
temperature and other safety devices) must be installed in the safety circuit in
accordance with current regulations for the system.
The cables of the safety system must be separated so that the outgoing signal
is not placed in the same cable as the incoming signal.

4.3 Explanation of the dierent sequence modes
1. Operation
This is the control unit voltage supply.
2. System test
In this status mode, the control unit undergoes
an internal test to verify correct functionality of
the hardware and software.
3. Preconditions for burner start-up
The control unit veries that the air pressure
switch is in the depressurised position and a test
of the fuel cut-off valve is carried out.
4. Heating requirement
The operating thermostat closes and voltage is
supplied to connection 5 so that the control unit
can start the burner.
5. Pre-purge begins
The control unit starts the fan. Connections 6 and
7.
6. Damper motor opens
Control unit connection 9 sends a command to
the damper motor to run at Max. mode. The
control unit detects that the damper motor’s end
position switch indicates successful transition
to the Max. load mode by supplying voltage to
the connection 8 input. The control unit also
performs a test to ensure that the air sensor
detects airow by monitoring connection 14.
7. Pre-purge
The combustion chamber is ventilated.
8. Damper motor closes
Following pre-purge, the control unit closes
connection 10. The control unit detects that
the damper motor is in the Low Load mode by
supplying voltage to connection 8 on the control
unit.
9. Ignition on
The control unit supplies voltage to the ignition
transformer by activating connection 16.
10. Fuel on
The control unit activates the fuel valve by
supplying voltage to connections 17 and 18 as
well as to direct ignition systems.
11. Flame indication
Ignition transformer turns off. The ame signal is
tested during this stage. If no ame is detected,
the burner enters Lockout mode.
12. Operating mode
Once a ame is stable, the control unit transitions
to Operating mode. There must be a ame signal.
Voltage is supplied to connection 20.
13. Shutdown
Shutdown occurs when the heating requirement
is met and power is cut off to the operating
thermostat connection 5 . The control unit closes
the fuel valves by cutting off power to outputs
18 and 20. The fan post-purges the combustion
chamber.
14. Lockout
The control unit enters lockout mode when an
internal or external fault is detected. The reset
button and the remote-reset connection can be
used to disable Lock mode. However, the control
unit will revert to lockout mode if the fault is not
rectied.
BURNER LOCKOUT
When lockout occurs, the LEDs indicate the cause. The control unit status is
saved in the memory, even in the event of a power outage. By pressing the
manual reset button on the control unit or remote reset.
!Note! At remote reset: maximum 5 reset attempts within a 15 min
period, after which qualied personnel must examine the burner
before further reset attempts are made.

5. Installation
5.1 General instructions
Oil burners must be installed in accordance with local regulations. The installer
must therefore be knowledgeable of the regulations pertaining to oil and
combustion.
Only oil suitable for the burner must be used and then in combination with a
suitable oil lter installed before the burner’s oil pump.
If the burner is replacing an existing burner, ensure that the oil lter is
replaced or cleaned. Installation may only be performed by qualied
personnel.
Care should be taken by the installer to ensure that electrical cables and oil
lines are not pinched or otherwise damaged during installation or servicing.
5.2 Inspection and maintenance
The system must be maintained at the interval specied in the service
schedule. If the burner is in a dirty environment, service should be done at
more frequent intervals.
5.3 Start-up
In order to obtain the correct setting, a ue gas analysis and temperature
measurement must be carried out. Otherwise, there is a risk of soot build up,
poor eciency or condensation in the chimney. The system must be ne-tuned
at start-up. The temperature in the chimney at a depth of 0.5 m must be at
least 60 °C to prevent condensation.
5.4 Preparing for installation
Check that the burner’s dimensions and capacity range are suitable for the
relevant boiler. The power data on the rating plate refers to the burner’s
minimum and maximum power.
5.5 Oil distribution
In order to achieve good reliability, it is important that the oil distribution
system is designed correctly.
Take the following into account:
• Selection of pipe diameter, pipe length and height difference; see
Pump instruction.
• Pipelines are to be laid with the fewest possible number of glands.
• The pipes are to be laid so that the oil supply hoses are not subjected
to tensile stresses or become excessively bent when the burner is
swung out or removed for servicing.
• The oil lter should be installed so that the lter cartridge can easily
be replaced or cleaned.
• Parts in contact with oil must be selected in materials that are capable
of withstanding the medium’s physical properties.
• When installing oil hoses, check that the inlet and return hoses are
tted to the appropriate connection on the oil pump. The hoses must
be located so that they do not bend or become subject to tensile load.
• Bleed the oil system. The oil pump/oil preheater may be damaged if
run dry. The vacuum in the suction line should not fall below 0.3 bar
during start-up.
