The intake-tube / burner system must not allow a loss of over 2 m
3
/h at 0.5mbar:
for instance, the above requirements will be met if you use flues for pressure exhaust of flue gases (the con-
densation kind).
➤
Make sure the air intake tube’s inlet is positioned so that it is not likely to be obstructed by foreign matter and,
where necessary, use suitable screens.
➤
The temperature of the incoming air must not exceed 40 °C;
➤
The inside diameter of the hose must be at least 80 mm.
➤
The intake tube can be up to 6 metres in length.
Warning: length is reduced if there are bends in the intake section.
For instance, using a tube with a smooth inside surface, you must allow for the following losses:
- for each 45° bend, tube length is reduced by 0.5 m;
- for each 90° bend, tube length is reduced by 0.8 m.
BURNER INSTALLATION MUST COMPLY WITH ONE OF THE INSTALLATIONS ILLUSTRATED IN THE
FIGURES BELOW.
➤
Under no circumstances should the air’s entry in the hose intake area be obstructed.
➤
The hose must not be blocked in any way or feature a shutting device (valves, membranes etc.).
➤
Coaxial tubes must not be installed for any reason.

3.4 HYDRAULIC SYSTEMS
It is necessary to install a filter on the fuel supply line.
◆
The pump is designed to allow working with two pipes.
◆
Before starting the burner make sure that the return pipe-line is
not clogged. An excessive back pressure ( ≥ 1 bar) would cause
the damage of the pump seal, with subsequent fuel leaks inside
the burner.
◆
In order to obtain one pipe working it is necessary to unscrew
the return plug (2), remove the by-pass screw (3) and then
screw again the plug (2) with a torque of 0.5 Nm.
The pump has a delivery pressure regulation device (5). Pressure
increases if turned in a clockwise direction, and decreases if
turned in the other direction. An indication of sensitivity is 1 bar
per turn. The pressure can be regulated in a range of 7 ÷ 15 bar.
Do not loosen the knob (8) and periodically check that it is
firmly fixed, for safety reasons.
Pressurised systems have a positive fuel pressure on intake to the
burner. Usually the tank is higher than the burner, or the fuel pump-
ing systems are on the outside of the boiler.
Figure 12 is an example of connection to a pressurised ring, no mat-
ter what position the ring feeder tank is in.
In the system in fig. 11, the table shows the maximum indicated lengths for the supply line, depending on
the difference in level, length and the diameter of the oil pipes.

Depressurised systems have a negative fuel pressure (depression) on intake to the burner.
Usually the tank is lower than the burner.
In the systems in figs. 13 and 14, the table shows the maximum indicated lengths for the supply line,
depending on the difference in level, length and the diameter of the oil pipes.
PRIMING PUMP
On the systems in fig. 13 and 14 start the burner and wait for the priming.
Should lock-out occur prior to the arrival of the fuel, await at least 20 seconds before repeating the operation.
In two pipe vacuum systems (fig. 14) the return line should terminate within the oil tank at the same level as
the suction line. In this case a non-return valve is not required.
Should however the return line arrive over the fuel level, a non-return valve is required.
This solution however is less safe than previous one, due to the possibility of leakage of the valve.

4.1 COMBUSTION ADJUSTMENT
In conformity with EN 267 the application of the burner on the boiler, adjustment and testing must be car-
ried out observing the instruction manual of the boiler, including verification of the CO and CO
2
concentra-
tion in the flue gases, their temperatures and the average temperature of the water in the boiler. To suit the
required appliance output, fit the nozzle then adjust the pump pressure and the air adjustment, in accord-
ance with the following schedule.
The values shown in the table are measured on a CEN
boiler (as per EN 267), if they refer to 12.5% CO
2
at sea
level (1013 hPA) and with light oil and room temperature
of 20°C, and combustion chamber pressure of 0 mbar.
WARNING:
Combustion air is drawn in from outside, meaning there may
be notable changes in temperature, which can affect the
percentage of CO
2
. You are advised to adjust CO
2
in accor-
dance with the graph featured. E.g.: outside air temperature
20 °C, adjust CO
2
to 12% (± 0.2%).
4.2 NOZZLES RECOMMENDED
Delavan type W; Hago type SS;
Steinen type Q; Danfoss type S.
Angle : 60° - In most cases.
80° - In case of flame detachment, during ignitions at low temperatures.
4.3 PUMP PRESSURE
12 bar: The pump leaves the factory set at this value.
14 bar: Improves flame retention; it is therefore suitable for ignitions at low temperatures.

4.6 AIR ADJUSTMENT,
(fig. 19)
Depending on burner output, air must be adjusted by turning
the feeder (2) first, followed by the knob (3).
To adjust, proceed as follows:
➤
Loosen the three screws (1).
➤
Turn the feeder (2), positioning it according to the values
given in the table on page 10.
➤
Tighten the three screws (1) with a driving torque not
exceeding 0.8 Nm.
Warning
It is essential you make sure the feeder is screwed on suf-
ficiently tightly to avoid de-setting the burner while it is in
operation.
This is done by turning the knob (3). Turning clockwise
limits the cross-section of the air passage area and increases CO
2
value. The opposite occurs when turned
anticlockwise.
Adjustments in the table on page 10 are given as an approximate guide only.
Each system features operating conditions that cannot be known in advance: actual nozzle delivery, pressure or
vacuum in the combustion chamber, necessary excess air etc...
All these conditions may call for a different air setting.
➤
Under no circumstances should the air's entry in the knob area (3, fig. 19) be obstructed.
➤
Placing fingers or tools of any kind inside the knob’s intake opening (3, fig. 19) is prohibited.
➤
Check the position of the feeder and knob as indicated in the table on page 10.

5. MAINTENANCE
The burner requires periodic maintenance carried out by a qualified and authorised technician in conformity
with legislation and local standards.
Periodic maintenance is essential for the reliability of the burner, avoiding the excessive consumption of
fuel and consequent pollution.
Before carrying out any cleaning or control always first switch off the electrical supply to the
burner acting on the main switch of the system.
THE BASIC CHECKS ARE:
➤
Check that there are no obstructions or bends in the supply or return oil pipes, in the air intake pipes and the
combustion product discharge tubes.
➤
Clean the filter in the oil suction line and in the pump.
➤
Clean the flame sensor (see fig. 16, page 9).
➤
Check for correct fuel consumption.
➤
Replace the nozzle (4, fig. 17, page 11) and check the correct position of electrodes (fig. 18, page 11).
➤
Clean the combustion head in the fuel exit area.
➤
Leave the burner working without interruptions for 10 min. and set rightly all the components stated in
this manual. Then carry out a combustion check verifying:
●
Smoke temperature at the chimney;
●
Content of CO
2
(%);
●
Content of CO (ppm);
●
Smoke value according to opacity smokes index according to Bacharach scale.
5.1 ACCESS TO THE FAN, (see Fig. 20)
IMPORTANT
➤
Perform maintenance work only when strictly nec-
essary, taking great care not to damage or unbal-
ance the fan during cleaning.
➤
Take careful note of the original position before
beginning any of these operations.
Proceed as follows:
➤
Unscrew the three screws (1) and remove the air
adjustment unit (2). At this point, you can clean the fan:
vacuum up any impurities, taking care they do not enter
the air circuit.
➤

6. FAULTS / SOLUTIONS
Here below you can find some causes and the possible solutions for some problems that could cause a fail-
ure to start or a bad working of the burner. A fault usually makes the lock-out lamp light which is situated
inside the reset button of the control box (7, fig. 1, page 1).
When lock out lamp lights the burner will attempt to light only after pushing the reset button. After this if the
burner functions correctly, the lock-out can be attributed to a temporary fault.
If however the lock out continues the cause must be determined and the solution found.
WARNING
The manufacturer cannot accept responsibility for any damage to persons, animals or property due to error in
installation or in the burner adjustment, or due to improper or unreasonable use or non observance of the
technical instruction enclosed with the burner, or due to the intervention of unqualified personnel.
