HYDRAULIC SYSTEMS
Warning: before starting the burner make sure that the return pipe-line is not clogged: any obstruction
would cause the pump seals to break.
The pump vacuum should not exceed a
maximum of 0.4 bar (30 cm Hg).
Beyond this limit gas is released from
the oil.
Oil lines must be completely airtight.
The return line should terminate in
the oil tank at the same level as the
suction line; in this case a non-return
valve is not required.
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 then 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.
RECOMMENDED NOZZLES: Monarch type R
Delavan type W - B
Steinen type S - Q
Danfoss type S
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.
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 reg-
ulating rod, till the terminal plane of the blast
tube is level with the set-point, as indicated in
the schedule.
In the sketch on the left, the combustion head is
set for an output of 1.50 GPH at 12 bar, while
the shutter is level with set-point 3, as required
by the above schedule.
Combustion head settings indicated in the
schedule are valid for most cases.
The setting of the fan output according to the installation 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 running, operate on the rod (1) with a 6 mm spanner (2) as follows (see fig. 7, page 7).

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 com-
bustion chamber and thus increasing its pressure. The
CO2improves and the adhesion of the flame to the dif-
fuser tends to reduce.
(This setting is not advisable for ignitions at low temper-
atures).
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: (fig. 8)
The mobile air damper (A) operated by the jack (B)
assures the complete opening of the air intake.
The regulation of the air-rate is made by adjusting the
fixed air damper (C), after loosing the screws (D). When
the optimal regulation is reached, screw tight the
screws (D) to assure a free movement of the mobile air
damper (A).
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 unpre-
dictable working conditions: actual nozzle output; posi-
tive 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 at
page 6;
– 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.
NOTE: When the burner works at a firing rate higher
than 9 kg/h remove the panel fitted inside the
metal cover. (See figure 9).

BURNER START-UP CYCLE
ADJUSTMENTS, TO AVOID FLAME - DETACHMENT, AT BURNER - IGNITION
This inconvenience can occur, when the temperature of the gas-oil decreases below + 5 °C.
1) CORRECT POSITIONING OF THE ELECTRODES
See figure 10.
2) PUMP - SETTING
The pump is factory set, at a pressure of 12 bar.
When the temperature of the light oil decreases below + 5 °C, increase the pressure to 14 bar.
3) COMBUSTION-HEAD SETTING
Regulate the combustion-head one set-point further ahead than indicated in the instructions.
Example: the instructions require to set the combustion-head on set-point 3.
Instead, the setting is made on set-point 4.
4) FAN - AIR DAMPER ADJUSTMENT
Adjust the damper, reducing the excess air until the Bacharach number is not near 1
(i.e. a combustion with the lowest possible excess-air).
Attention:
Before assembling or remo-
ving the nozzle, loosen the
screw (A) and move the elec-
trodes ahead.

风压 .
烟气中 CO2含量减少但火焰燃烧状况得到改善 .
(
温度较低点火时可采取此设置 ).
左旋 : (
–的方向 ), 可减少进入燃烧室的风量同时增加其
压力 .
烟气中 CO2含量增加但火焰贴盘现象减少 .(
温度较低点
火时不宜采取此设置
).
任何情况下燃烧头的设定值不要偏离上图所示的参考值
太多（不能大于 1 个刻度）. 调节杆转 3 圈相当于一个刻
度; 可通过端面上的孔 (3) 来方便的记录所转的圈数 .
风门挡板调整 :(图. 8)
可调风门挡板 (A) 通过液压装置 (B) 驱动 , 确保风门入
口完全打开 .
拧松螺钉 (D) 后调整固定风门 (C) 来调节风量 .
当达到合适的风门位置后, 拧紧螺钉(D) 以确保可调风门
(A) 的运行 .
上表所示的设置值是在燃烧器安装金属外壳和燃烧室背
压为零的情况下测得 .
每一次安装 , 都可能有不同状况 : 实际喷嘴出力 , 燃烧室
的正负压力 , 空气过剩量 ,等等 .
所有这些条件都需要不同的风门挡板设置 .
应考虑燃烧器是否装上金属外壳对进风量大小的影响 .
因此建议按以下步骤进行 :
– 按表中所示 (4, p 6)调节风门挡板 ;
– 安装外壳 , 仅固定上部螺钉 ;
– 检查烟气等级 ;
– 如必须调整风门挡板 , 拧下上部螺钉后移开外壳 ,调
节风门挡板 ,然后安装外壳并再次检查烟气等级 .
注意 :
如燃烧器出力大于 9kg/h，请移开金属外壳内壁的挡板 .

点火电极的设定 (参见图 . 10)
燃烧器启动程序
在燃烧器点火时 , 为避免火焰不稳 , 可调整电极位置
当轻油油温低于 +5 °C, 有可能引起点火困难 .
1) 正确的点火电极位置
参见图 . 10.
2) 油泵压力 - 设定
油泵压力出厂时设定为 12 bar.
当轻油油温低于 +5 °C, 将油压增加到 14 bar.
3) 燃烧头的设定
可将燃烧头的设定点调整得比上表中所给设置值大一个设定点
例如 :说明书中所给设定值为 3, 此时可将设定点调整到 4.
4) 风门挡板调整
调整减震器，减少过量空气直至黑度指数不接近 1.
(即在最小过量空气的条件下燃烧 ).
注意 :
在更换或安装喷嘴前 , 拧松 螺
钉(A) 并将电极向前移动 .
