WARNING
The pump is supplied for use with a two pipe sys-
tem. For use on a one pipe system, it is necessary
to remove the by-pass screw (A).
Priming the pump
Loosen the plug of the vacuum gauge (5, Fig. 1,
page 1) and wait until the fuel flows out.
SYSTEM NOT
PERMITTED IN ITALY
When the return line arrives over the fuel level, a non-return
valve must be used.
This solution however is less safe than previous one, due to
the possibility of leakage of the valve.
Priming the pump
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.
A filter must be installed on the suction fuel line.

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 nozzle, the settings of the combustion head 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.
(* see Fig. 7, page 8)
NOZZLES RECOMMENDED: Monarch type R Danfoss type S
Delavan type W - E Satronic type S
Steinen type Q
COMBUSTION HEAD SETTING: This is done when fitting the nozzle, with the blast tube removed. It
depends on the output of the burner and is carried out by
rotating the regulating rod, till the terminal plane of the blast tube
is level with the set-point, as indicated in the schedule.
For this application, the head should be
fully open (at notch 6).

Combustion head settings indicated in the schedule are
valid for most cases.
The setting of the fan output according to the installa-
tion should normally be done only through the air
damper. Should one subsequently want to retouch also
the setting of the combustion head, with the burner run-
ning, operate on the rod (1) with a 6 mm spanner (2) as
follows:
TURN TO THE RIGHT: (SIGN +)
In order to increase the volume of air entering the com-
bustion chamber and thus diminishing its pressure.
There is a reduction of CO2and the adhesion of the
flame to the air diffuser disc improves.
(Setting advisable for ignitions at low temperatures).
TURN TO THE LEFT: (SIGN –)
In order to reduce the volume of air entering the combustion chamber and thus increasing its pressure. The
CO2improves and the adhesion of the flame to the diffuser tends to reduce. (This setting is not advisable for
ignitions at low temperatures).
In any case do not bring the combustion head setting more than one point away from that indicated in the
schedule. One set-point corresponds to 3 turns of the rod; a hole (3) at its end facilitates counting the number
of turns.
AIR DAMPER ADJUSTMENT: 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 output 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 (point 3);
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.

FUEL HEATING
In order to obtain smooth starting and operation across its output range the burner is fitted with an electric
resistance, which heats up the gas oil in the nozzle line.
This resistance is energized when the thermostat calls for heat and after a delay of approximately two min-
utes depending on room temperature, the motor will start.
The resistance remains inserted and locks-out on the shut-down of the burner.
ATTENTION
Should you want to cut off the electric resistance (on
setting the burner or when the ambient temperature
does not require it, etc...), take the plug off the panel of
the control box and plug it into the “Resistance OFF”.
In this case the burner starts up when the thermostats
close.
NOTE
The warning light (LED) is ON but when the resistance
works. It is OFF when the resistance is disconnected or
broken.

FAILURE DETECTION ON HEATING DEVICE
NORMAL OPERATION (Fig. 8)
The plug fitted in the panel is placed in the position corresponding to “Resistance ON” .
When the remote control closes, the LED lights up and, after about two minutes, the burner starts up.
BURNER DOES NOT OPERATE
1) If the LED is OFF, the heating resistance placed in the nozzle-holder is off.
2) If the LED is ON and nevertheless the burner does not run, place the plug in the position corresponding
to “Resistance OFF” (Fig. 9).
If the motor runs, the delaying device inside the control box is out of order.
3) If the motor does not run, it means that the failure is neither in the panel nor in the resistance, but else-
where.

WARNINGS TO AVOID BURNOUT OR BAD COMBUSTION OF THE BURNER
– When the burner is stopped, the smoke pipe must be opened and effect a natural draught in the
combustion chamber. If the smoke pipe is closed, the burner must be drawn back till the extrac-
tion of blast tube from the furnace. Before operating in this way take the voltage off.
– The place, where the burner works, must have same openings suitable for the passage of air nec-
essary for combustion. To be sure about this, you have to control the smoke number of exhaust
gas with all the windows and doors closed.
– If in the place, where the burner works, there are air-breathings, check the existence of air-input
openings with dimensions suitable for the necessary air-exchange. In any case check that, when
the burner is stopped, the air-breathings do not draw warm smokes from pipes through the
burner.
– Turn the switch to position 1 before stopping the burner.
MAINTENANCE
The burner requires periodic maintenance carried out by a qualified and authorised technician in con-
formity with legislation and local standards.
Periodic maintenance is essential for the reliability of the burner, avoiding the excessive consump-
tion 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 there are no occlusions or obstructions in the inlet or return pipes, in the air suction areas and
in the combustion product waste pipe.
Clean the filter in the oil suction line and in the pump.
Check for correct fuel consumption.
Check that the burner electrical connections are correct.
Replace the nozzle and check the correct position of electrodes.
Clean the combustion head in the fuel exit area.
Check that the positioning of the combustion head is correct and that it is properly fixed to the
boiler.
Check that the air damper is positioned correctly.
Let the burner run at full capacity for about ten minutes, setting all the elements correctly as explained in
this manual. Then carry out the analysis of the combustion by checking:
- Smoke index as per the Bacharach scale; - CO2percentage (%); - CO content (ppm);
- NOx content (ppm); - Smoke temperature at the chimney.

燃烧调整
根据效率指令 92/42/EEC 对于使用在锅炉上的燃烧器，调整和测试必须根据锅炉的使用说明书来执行，包括
检验烟气中 CO 和CO2的含量，烟气温度和锅炉内热水的平均温度。
为使燃烧器达到额定的出力，首先安装好合适的喷嘴，然后根据下表对燃烧头的位置和风门挡板开度进行设
置。
下表中的值在 CEN 锅炉上测试得到 ( 根据欧盟燃油燃烧器 EN 267 标准 )。
测试条件为 CO2浓度为 12.5%，海平面高度，轻油，室温 20°C。
(* 见图 .7, 第8页)
推荐的喷嘴 :Monarch R 型Danfoss S 型
Delavan W - E 型Satronic S型
Steinen Q 型
燃烧头的设置 :安装喷嘴时设置，先拆下燃烧筒。根据燃烧器最大出力来设置
（如上表所示），通过旋转调节杆来设置，直到燃烧筒的端面与设定
