HYDRAULIC JACK OPERATION 7)(Fig. 1)
It is strongly recommended a periodic check of
the pump pressure operation (annually or bet-
ter every six months, if the burner operation is
continuous).
If the value is lower than 1 bar, compared to
that one of the initial setting, please check the
cleaning of the pump and line filters.
In case the pressure setting was not restora-
ble, please replace the pump, in order to guar-
antee that the pump pressure during the pre-
purge time is at least 3.7 bar.

3. INSTALLATION
THE BURNER MUST BE INSTALLED IN CONFORMITY WITH LEGISLATION AND LOCAL STANDARDS.
3.1 MOUNTING THE BURNER
Fix the flange (1) to the boiler door using screw and nuts, interposing the insulating gasket (see fig. 2).
The insulating gasket has six holes, which, if necessary, can be modified as shown in the figure 3.
Verify that the installed burner is lightly leaned towards the button (see fig. 4).
The burner is designed to allow entry of the flexible oil-lines on either side of the burner.

PRIMING PUMP:
On the system in fig. 6 it is sufficient to loosen the suction gauge connec-
tion (6, fig. 5) and wait until oil flows out.
On the systems in fig. 7 and 8 start the burner and wait for the priming.
Should lock-out occur prior to the arrival of the fuel, await at least 20 sec-
onds before repeating the operation.
The pump suction should not exceed a maximum of 0,4 bar (30 cm Hg).
Beyond this limit gas is released from the oil. Oil pipes must be completely
tight.
In the vacuum systems (fig. 8) 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 previ-
ous one, due to the possibility of leakage of the valve.

Check periodically the flexible pipes conditions.
Using kerosene, they have to be replaced at least every 2 years.
A metal bowl filter with replaceable micronic filter must be fitted in the
oil supply pipe.
The pump is designed to allow working with one pipe.
In order to obtain two pipes working it is necessary to unscrew the
return plug (2), screw the by-pass screw (3) and then screw again
the plug (2). (See fig. 5).
In the two pipes systems, before starting the burner make sure that
the return pipe-line is not clogged. An excessive back pressure
would cause the damage of the pump seal.

4. WORKING
4.1 COMBUSTION ADJUSTMENT
In conformity with Efficiency Directive 92/42/EEC the application of the burner on the boiler, adjustment and
testing must be carried out observing the instruction manual of the boiler, including verification of the CO and
CO2concentration in the flue gases, their temperatures and the average temperature of the water in the boiler.
To suit the required appliance output, fit the proper nozzle, then adjust the pump pressure and the air
damper opening in accordance with the following schedule.
The values shown in the table are measured on a CEN boiler (as per EN 267). They refer to 12.5% CO2at
sea level and with light oil and room temperature of 20 °C.
4.2 NOZZLES RECOMMENDED
Monarch type R - NS; Delavan type W - E; Steinen type Q - H; Danfoss type H - S.
4.3 PUMP PRESSURE
8 bar: pressure suitable for kerosene in most cases.
10 bar: maximum pressure for kerosene.
INCREASE PRESSURE
12 bar: pressure suitable for light oil in most cases.
14 bar: maximum pressure light oil.

4.5 AIR DAMPER ADJUSTMENT, (see fig. 11)
The mobile air damper (1) operated by the jack (2) assures the
complete opening of the air intake.
The regulation of the air-rate is made by adjusting the fixed air
damper (3), after loosing the screws (4). When the optimal
regulation is reached, screw tight the screws (4) to assure a
free movement of the mobile air damper (1).
The settings indicated in the schedule refer to the burner with
its metal cover fitted and the combustion chamber with “zero”
depression.
These regulations are purely indicative.
Each installation however, has its own unpredictable working
conditions: actual nozzle output; positive or negative pressure
in the combustion chamber, the need of excess air, etc.
All these conditions may require a different air damper setting.
It is important to take account of the fact that the air out-
put of the fan differs according to whether the burner has
its metal cover fitted or not.
Therefore we recommended to proceed as follows:
– adjust the air damper as indicated in the schedule;
– mount the cover, simply by means of the upper screw;
– check smoke number;
– should it become necessary to modify the air output, remove the cover by loosening the screw, adjust
the air damper, remount the cover and finally recheck the smoke number.

5. MAINTENANCE
The burner requires periodic maintenance carried out by a qualified and authorised technician in conform-
ity with legislation and local standards.
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:
Leave the burner working without interruption for 10 min., checking the right settings of all the components
stated in this manual.
Then carry out a combustion check verifying:
CO2(%) content Smoke temperature at the chimney CO content (ppm).
5.1 MAINTENANCE POSITION
Insert in the hole (1) the pin (2) and fix the burner with the nut (3) fitted wrong-side up.
