3. INSTALLATION
THE BURNER MUST BE INSTALLED IN CONFORMITY WITH LEGISLATION AND LOCAL STANDARDS.
3.1 BOILER FIXING
Put on the flange (1) the screw and two nuts, (see fig. 3).
Widen, if necessary, the insulating gasket holes (5).
Fix the flange (1) to the boiler door (4) using screws (2) and (if necessary) the nuts (3) interposing the
insulating gasket (5), (see fig. 2).
3.2 FUEL SUPPLY
The burner is designed to allow entry of the oil supply pipes on either side.
Depending on the oil supply pipes position (to the right or to the left hand side of the burner) the fixing plate
(1) and closing plate (2) should be reversed, (see fig. 4).

3.3 HYDRAULIC SYSTEMS
It is necessary to install a filter on the fuel supply line.
H= difference of level; L= max. length of the suction line; I. D. = internal diameter of the oil pipes.
PRIMING PUMP:
On the system in fig. 6 it is sufficient to loosen the suction gauge
connection (5, 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 seconds
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 re-
quired. 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.

OThe pump is designed to allow working with two pipes.
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). (See fig. 5).
OBefore 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 CO2
concentration in the flue gases, their temperatures and the average temperature of the water in the boiler.
To suit the required appliance output, choose the proper nozzle and adjust the pump pressure, the setting 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
4.2 RECOMMENDED NOZZLES: Delavan type W - B; Danfoss type S - B
Monarch type R ; Steinen type S - Q.
For 1.75 - 2.00 - 2.25 GPH nozzles it is advisable to use
full cones.

THE ACCESSIBILITY TO THE NOZZLE, THE
DIFFUSER DISC AND THE ELECTRODES IS
MADE EASY IN 2 WAYS:

Remove the burner out of the boiler, after loosing
the fixing nut to the flange.
Hook the burner to the flange (1), by removing
the blast tube (2) after loosing the fixing
screws (3).
Remove the small cables (4) from the electrodes
and the diffuser disc-holder assembly (5) from

ing screw (3, fig. 12, page 7).
Screw the nozzle (6) correctly and tighten
it as shown in the figure.

4.5 COMBUSTION HEAD SETTING (see fig. 11, page 7)
It depends on the output of the burner and is carried out by rotating clockwise or counterclockwise the setting
screw (5) until the set-point marked on the regulating rod (9) is level with the outside plane of the nozzle-holder
assembly (1).
In the sketch the combustion head is set for an output of 1.50 GPH at 12 bar.
The set-point 3of the regulating rod (9) is at the same level with the outside plane of the nozzle-holder as-
sembly (1) as shown in the schedule.
4.6 AIR DAMPER ADJUSTMENT (see fig. 11, page 7))
To vary the setting adjust the screw (7) after loosing the nut (8).
When burner shuts down the air damper automatically closes till a max. chimney depressure of 0.5 mbar.
4.7 BURNER START-UP CYCLE
Lock out is indicated by a lamp on the control box (3, fig. 1, page 1).
5. MAINTENANCE
The burner requires periodic maintenance carried out by a qualified and authorised technician in conformity
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:
Check that there are not obstructions or dents in the supply or return oil pipes.
Clean the filter in the oil suction line and in the pump.
Clean the photoresistance, (7, fig. 1, page 1).
Check for correct fuel consumption.
Replace the nozzle (see fig. 10, page 6) and check the correct position of electrodes (fig. 12, page 7).
Clean the combustion head in the fuel exit area, on the diffuser disc.
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; Contentof CO2(%); ContentofCO(ppm);
Smoke value according to opacity smokes index according to Bacharach scale.

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
(3, 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.
FAULTS POSSIBLE CAUSES SOLUTION
The burner doesn’t
start when the limit
thermostat closes.
Lack of electrical supply.
Check presence of voltage in the
L1 - N clamps of the 7 pin plug.
Check the conditions of the fuses.
Check that safety thermostat is not
lock out.
The photoresistance sees false light. Eliminate the light.
Start thermostats are faulty. Replace them.
The connections in the control box
are wrongly inserted. Check and connect completely all the plugs.
Burner runs normal-
ly in the prepurge
and ignition cycle
and locks out after 5
seconds ca.
The photoresistance is dirty. Clear it.
The photoresistance is defective. Change it.
Flame moves away or fails.
Check pressure and output of the fuel.
Check air output.
Change nozzle.
Check the coil of solenoid valve.
Burner starts with an
ignition delay.
The ignition electrodes are wrongly
positioned. Adjust them according to the instructions of this manual.
Air output is too high. Set the air output according to the
instructions of this manual.
Nozzle dirty or worn. Replace it.

油泵启动 :
在图 . 6 所示系统中，松开油压表接口螺钉 (5, 图. 5) 直到有油流出就可以了 .
在图 . 7 和图 8 所示系统中启动燃烧器直到油泵充油 .
如在燃料到达油泵之前锁定 , 至少等 20 秒才能再次启动 .
油泵进油真空度不能超过 0.4 bar (30 cm Hg).
大于这一值，气体可能从油中分离出来，所以油管一定要完全拧紧。
I在低位油箱系统中 (图. 8)回油管应回到油箱中与入油管相同的水平高度，在这种
情况下，不需止回阀，然而如果回油管回到比燃料表面高的位置，必须装一个止回
阀。
这种方法不如前一种方法，因为阀门有可能漏油 .

4.1 燃烧调节
根据效率标准 92/42/EEC，调试燃烧器必须参考锅炉的使用说明 , 这一工作包括调整烟气中的 CO 和CO2，烟温
及锅炉中的平均水温。
要达到所需要的出力，应按照下表选择合适的喷嘴，调整泵压，设定燃烧头和风门 .
表中的数值由 CEN 锅炉测得 ( 按照 EN 267).
参考条件：12.5% CO2，在海平面，油温和室温为 20 °C.
4.2 建议的喷嘴 :Delavan 类型 W - B; Danfoss 类型 S - B
Monarch 类型 R ; Steinen 类型 S - Q.
对于 1.75 - 2.00 - 2.25 GPH 的喷嘴建议使用全空角的 .
维修位置
可按如下的 两种方法简便的安装喷嘴，旋
流盘和电极 :

松开法兰盘的固定螺钉后从锅炉上移开燃烧器 .
松开螺钉 (3)后移走风管 (2) ，将燃烧器悬挂在法
兰(1)上.
松开固定螺钉 (3, 图. 12, P. 7)后从电极上移走电
缆(4)，从喷嘴座上移走旋流盘组件 (5).
正确的拧上喷嘴 (6)，然后按图所示拧紧 .

4.5 燃烧头设定 (参见图 . 11,P. 7)
根据燃烧器的出力 , 通过顺时针和逆时针转动 设定螺丝 (5) 来进行 , 直到设定的调节杆 (9) 上的刻度点与喷嘴座
(1) 的外边缘对齐 .
在简图中 , 燃烧器的设定对应于 1.50 GPH 油压为 12 bar 时的出力 .
如图所示 , 调节杆 (9) 上的设定点 3与喷嘴座 (1) 的外边缘对齐 .
4.6 风门调节 (参见图 . 11, P. 7)
松开螺钉 (8) 后调节螺钉 (7) .
燃烧器关机后 , 风门会自动关闭 , 除非烟囱处的最大负压力超过 0.5mbar.
4.7 燃烧器启动程序
由控制盒上的信号灯指示燃烧器锁定 (3, 图. 1, P1).
5. 维护
燃烧器需要由有资格的技术人员按照当地法规和标准进行定期性的维护 .
维护对于燃烧器的可靠性是必要的 , 可避免燃料的过量消耗以及随之而来的污染 .
在进行维护清理之前 , 必须将系统的主电源开关关掉 , 以切断燃烧器的电源 .
基本的检查有 :
检查进油管及回油管是否有堵塞或凹陷 .
清理进油管及油泵中的过滤器 .
清理光电管 ,(7, 图. 1, P. 1).
检查燃料消耗是否正常 .
如需要更换喷嘴 ( 图. 10,P. 6) 和检查电极的位置 ( 图. 12, P. 7).
清理燃烧头中燃料出口和旋流盘 .
让燃烧器不间断地运行 10 分钟 , 按手册正确设置所有组件 , 然后进行燃烧测试以检查以下各项 :
烟囱处的烟温 ; CO2(%)的含量;CO (ppm)的含量;
测量烟气中的黑度值 .
