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.

4. Installation
4.1 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.
4.2 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.
4.3 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.
4.4 Delivery inspection
Make sure everything is delivered and the goods have not been damaged
during transit. If something is wrong with a delivery, report it to the supplier.
Transport damage must be reported to the shipping company.
4.5 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.

propertyandpersonalinjury.
4.6 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.
4.7 Electrical connection
• Before work on the electrical connection, the current must be
disconnected so that the installation is isolated.
• Electrical connection must be done in accordance with the applicable
regulations.
• Burners must be connected to an all-pole switch.
• Connection must conform to the wiring diagram.
• Use appropriately sized fuses.

5.1 Example of basic setting
ST 146 KS
Burner output: 88 kW
Estimated nozzle output: 88 / 11.86* =7.42 kg/h
(* Calorc value Fuel oil =11.86 kWh/kg)
This provides the following nozzle according to the nozzle table, (see Technical
data).
Nozzle: 2.00 Gph
Pump pressure: 10.0 bar
Setting values for 88 kW according to basic setting diagram, (see Technical
data).
Air setting: = 19.0
Insert setting: =15.0
ST 146 KSV
Burner output: 88 kW
Output increase, for burners with
preheater:
88 x 1.06 = 93 kW
Estimated nozzle output: 93 / 11.86* =7.84 kg/h
(* Calorc value Fuel oil =11.86 kWh/kg)
This provides the following nozzle according to the nozzle table, (see Technical
data).
Nozzle: 2.00 Gph
Pump pressure: 11.0 bar
Setting values for 88 kW according to basic setting diagram, (see Technical
data).
Air setting: = 19.0
Insert setting: =15.0

5.1.1 Insert control
The burner is equipped with a lever that changes the position of the brake
plate in the burner tube. This is used to set the correct pressure drop across
the combustion assembly, thereby obtaining good combustion without
pulsation.
The setting to be used depends on, among other things, the output settings
and overpressure in the boiler
Setting the brake plate
• Small column: turn the screw left
• Large column: turn the screw right
Setting the brake plate position affects air ow. Therefore, it is always necessary
to  ne-tune air ow using the burner’s air ow regulator.
5.1.2 Air intake adjustment
Setting the air intake is very important to achieve good combustion with
neither too much nor too little air. To adjust the combustion air ow, turn the
air ow regulator lever using an Allen key. The extent to which the air ow lever
must be open is determined by the heat output and overpressure in the boiler
as well as other settings on the burner such as the position of the brake plate.
5.1.3 Setting the air quantity
Turn the air intake clockwise to increase air ow and anticlockwise to decrease
air ow.
