The table applies to oils with a viscosity of 4.4 mm2/s (cSt) at a density of 830 kg/m3.
2.8.1 Burner with preheater
Allow for a reduction in oil quantity of 5–20% with preheating owing to:
• Temperature increases at the nozzle.
• Nozzle design.
• Capacity (the higher the capacity the lower the difference).

3. Installation
3.1 Delivery checks
Check that everything has been delivered and that the goods are not
transport damaged. Any delivery faults must be reported to the supplier.
Transport damage must be reported to the forwarder.
3.2 Preparations for installation
Check that the burner’s measurements and capacity range is suitable for
the boiler in question. The power information on the data plate refers to the
burner’s max. and min. power.
3.3 Oil supply
In order to achieve good operational reliability it is important that the oil
supply system is laid out correctly.
Observe the following:
• Choice of pipe diameters, pipe lengths and height differences (refer to
pump instructions).
• Piping should be run with a minimum of joints/compression fittings.
• Pipework must be laid out so that oil hoses are not subjected to
tension or overbending when the burner is swung out or removed for
service.
• The oil filter should be installed so that the filter cartridge can easily be
replaced
3.4 Electrical connection
Before electrical installation is begun, electricity must be switched off at
the main switch. If the boiler has a 7-pole or a 4-pole Eurostecker (only on
2-stage burners), these often fit directly to the burner. Otherwise use the
connectors supplied. The operating thermostat, the max. thermostat and the
inspection hatch (where fitted) interlock can then be wired in series on the
incoming phase connected to L1 or connected between T1 and T2. In the
first mentioned case a jumper is installed between T1 and T2.
(Refer to connection in the section Electrical equipment).
3.5 Choice of nozzle
(Technical data): Recommended nozzle and nozzle table.
3.6 Brake plate and airflow setting
Before operations basic burner setting may be made according to the
diagram. (Refer to basic settings). Note that this only refers to the basic
setting; the setting must be adjusted after the burner has been started.
At this time flue gas analysis and soot measurement must be carried out.
!If any electrical connection is used other than that recommended
by Enertech, there may be a risk of equipment damage and personal injury.

3.7 Burner installation
3.7.1 Hole pattern
Check that the hole pattern matches the flange supplied.
(Refer to Technical data.)
3.7.2 Burner installation
1. Install the flange and the gasket on the boiler.
2. Attach the front piece to the flange.
3. Insulate between the burner register and the boiler cover for reduced
heat radiation.
4. Install the selected nozzle. (Refer to Technical data.)
5. Install the brake plate and check the ignition electrodes (refer to Burner
service.).
6. Install the burner body to the front piece and lock with screw (E).
3.7.3 Oil pipes
1. Check the oil pipe dimensions. (Refer to Pump Instructions.)
2. The oil filter should be installed in the oil supply line. If an air separator is
fitted, the oil filter should be installed before the air filter to increase the
life span of the filter.
3. For one-pipe systems the return plug must be removed. (Refer to
Pump Instructions.)
4. When installing oil hoses, check that the supply and return hoses are
connected to the correct connections on the oil pump. The hoses
must be run so that they are not bent or tensioned.
5. Purge the oil system. The oil pump will be damaged if it is run dry.
6. The vacuum should not be lower than 0.3 bar depression in the suction
line at start up.
3.7.4 Electrical connection
If the boiler lacks ready-connected plugs, connect using the supplied plug,
X2 in accordance with the wiring diagram.
1. Disconnect the power at the main switch.
2. Wire the Eurostecker X2 as in alt. 1–3 (refer to Electrical equipment).
3. Connect the Eurostecker X2 to the burner.
4. Switch on the power at the main switch.

4. Basic settings
4.1 Example of basic setting
4.1.1 Choice of nozzle
BF1 FU 63-16
Burner output 30 kW
Estimated nozzle output: 30 / 11,86* = 2,53 kg/h
Choice of nozzle according to table. (Refer to Technical data.)
According to the nozzle table, the following nozzle is indicated:
Nozzle: 0,65 Gph
Pump pressure: 11,0 bar
BF1 FU 63-16/FUV 63-16
Burner output 30 kW
Because of preheater, output is adjusted upward for choice of nozzle
according to table.
Estimated nozzle output: 30 x 1,06 = 31,8 kW
31,8 / 11,86* = 2,68 kg/h
Choice of nozzle according to table. (Refer to Technical data).
According to the nozzle table, the following nozzle is indicate
Nozzle: 0,75 Gph
Pump pressure: 9,5 bar
* Calorfic value Light oil = 11,86 kWh/kg
4.1.2 Basic setting
Setting values for 30 kW according to basic settings tables.
(Refer to Technical data FU 63-16).
Air setting = 11,0
Insert setting = 4,0

4.1.3 Nozzle assembly adjustment
The burner is fitted with a regulator which changes the brake plate position
in the blast tube. This is used to set the correct pressure drop across the
combustion assembly and thereby achieve good combustion without
pulsation.
The setting to be chosen is dependent among other things on set output
and furnace pressure.
Brake plate setting
• Less diffusion: turn screw to left.
• More diffusion: turn to right.
Setting brake plate position affects air flow. It is therefore always
necessary to adjust the air with the burner air regulator afterwards.
4.1.4 Air intake adjustment
Air settings are very important for achieving good combustion with neither
too much, nor too little, air. Adjustment of combustion airflow is carried out
by turning the air regulator with an Allen key. How far open the air regulator
must be is determined by output, furnace pressure and other burner settings
such as blast tube position.
4.1.5 Method of adjusting air quantity
Setting the air regulator is dependent on how the screw (with which air
regulation is adjusted) is installed. If the air intake is installed underneath
as shown in illustration Ι, turning the screw clockwise will reduce airflow,
and anticlockwise increase it. If the air intake is installed on top as shown
in illustration Π, clockwise adjustment increases airflow, and anticlockwise
reduces it.
4.1.6 Inlet cone, air adjustment
Airflow is also affected by the position of the inlet cone. However, it is
extremely rare that this needs to be adjusted; it should be left in the
standard STD position to achieve good starts and operations. (A cast-in
arrow on the fan housing indicates the position of the inlet cone. In addition
to the scale on the inlet cone casting, there is also a mark (M) indicating the
factory setting.)
