1. General Information
The burner may only be used for its intended purpose in accordance with the
product’s technical data.
We reserve the right to make design changes and cannot be held liable for any
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.
• If something is wrong with a delivery, report it to the supplier.
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.
• Fire extinguisher with Class BE recommended.
• Make sure when installing the burner that there is enough space to
service the burner.
• The electrical installation must be professionally carried out in
accordance with current mains electricity regulations and in a
professional manner.
• Make sure that the burner is suitable for the application (see Technical
Data).
• All components must be installed without being bent, twisted or
subjected to mechanical or thermal forces that affect components.

5Bentone
• Care must be taken by the installer to ensure that no electrical cables
or fuel lines are pinched or otherwise damaged during installation or
service.
• Flame tubes, fan wheels and air dampers, for example, may contain
sharp edges.
- before  rst start:
• 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.

1.3 General requirements FAME/RME
• The fuel must meet the requirements of standard EN 14214 for FAME.
• The fuel must be stored and used according to the manufacturer’s
instructions. It should typically be used within 6 months of
manufacture. Fuel that is allowed to age loses its oxidation stability
and produces aggressive constituents. These may cause oxidation
damage to components in the oil system. The fuel should be stored in
a cool and dark area.
• The RME tank must be made of metal or dark coloured plastics
approved for the fuel.
• Burners fuelled by FAME (RME) are – and must be – equipped with
parts designed for this fuel. This applies to oil-related parts such as
the pump, solenoid valve, oil lter and hoses.
• Oil hoses must be of high-quality uoride rubber or PTFE intended for
FAME/RME, and the hoses must be tted with re-retardant sleeves in
order to satisfy requirements according to EN-ISO 6806.
• The installation should be performed as a single-pipe system. Copper
should be avoided the fuel system since the fuel and copper have an
oxidising effect on each other.
• Annual cleaning and checking for the presence of water in the tank
should be done to avoid corrosion and microorganisms.

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.

Flame signal
When operating at high power or low air excess and HVO/XTL is used as fuel,
the ame signal may deteriorate (blue ame), the signal lamp in the reset
button ashes green.
By lowering the air velocity or changing the ame detector to QRC1 A1, the
ame signal can be improved.

3.1 Safety system
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.
