INFORMATION ABOUT THE INSTRUCTION MANUAL
INTRODUCTION
The instruction manual supplied with the burner:
- is an integral and essential part of the product and must not be sepa-
rated from it; it must therefore be kept carefully for any necessary
consultation and must accompany the burner even if it is transferred
to another owner or user, or to another system. If the manual is lost
or damaged, another copy must be requested from the Technical
Assistance Service of the area;
- is designed for use by qualified personnel;
- offers important indications and instructions relating to the installation
safety, start-up, use and maintenance of the burner.
DELIVERY OF THE SYSTEM AND THE INSTRUCTION MAN-
UAL
When the system is delivered, it is important that:
- The instruction manual is supplied to the user by the system manu-
facturer, with the recommendation to keep it in the room where the
heat generator is to be installed.
- The instruction manual shows:
- the serial number of the burner;
- the address and telephone number of the nearest Assistance
Centre;
- The system supplier carefully informs the user about:
- the use of the system,
- any further tests that may be necessary before the system is
started up,
- maintenance and the need to have the system checked at least
once a year by the manufacturer or another specialised techni-
cian.
To ensure a periodic check, recommends the drawing up
of a Maintenance Contract.

It is strongly recommended a periodic check of the
pump pressure operation (annually or better 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 restorable,
please replace the pump, in order to guarantee that
the pump pressure during the pre-purge time is at
least 3.7 bar.

MOUNTING THE BURNER
It is necessary that the insulating gasket
(9, fig. 1) is placed between the boiler
door and the burner flange.
This insulating gasket has six holes,
which, if necessary, can be modified as
shown on the drawing on the right.
Verify that the installed
burner is lightly leaned
towards the button.
(See figure 2).
The burner is designed
to allow entry of the flex-
ible oil-lines on either
side of the burner.

OIL LINES
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 air-
tight. The return line should termi-
nate 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 prim-
ing. Should lock-out occur prior to the
arrival of the fuel, await at least 20 sec-
onds 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, adjust-
ment and testing must be carried out observing the instruction manual of the boiler, including verifi-
cation 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.
NOZZLES RECOMMENDED: Monarch type R - NS; Delavan
type W - A - E
Steinen type H - Q ; Danfoss type H - B
Angle:60°:in most cases.
80° : in case of flame detachment, during igni-
tions at low temperatures.
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 regulating rod, till the terminal
plane of the blast tube is level with the set-point, as indi-
cated in the 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:
Turn to the right: (sign +), in order to increase the vol-
ume of air entering the combustion 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 tempera-
tures).
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 mobile air damper (A) operated by the jack (B) as-
sures 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 unpredictable
working conditions: actual nozzle output; positive or neg-
ative 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 (4, page 5);
– 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.

ADJUSTMENTS, TO AVOID FLAME - DETACHMENT, AT BURNER - IGNITION
This inconvenience can occur, when the temperature of the gas-oil decreases below +8 °C.
1) CORRECT POSITIONING OF THE ELECTRODES
2) NOZZLE: ATOMIZING CONE
Choose empt ies or semi-empt ies cones.
For exemple: Delavan type A - E; Steinen type H; Danfoss type H.
3) PUMP - SETTING
The pump is factory set, at a pressure of 12 bar.
When the temperature of the gas-oil decreases below +8 °C, increase the pressure to 14 bar.
4) 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 2.
Instead, the setting is made on set-point 3.
5) FAN - AIR DAMPER ADJUSTMENT
Adjust the air damper of the fan, such as to obtain a smoke-number not inferior to 1.
(i.e. a combustion with the lowest possible excess-air).

燃烧调整
根据燃烧器运用在锅炉上的效率标准 92/42/EEC，调试燃烧器必须参考锅炉的使用说明书 , 这一工作包括调整烟气
中的 CO 和CO2含量，烟温及锅炉的平均水温。
要达到所需要的出力，应按照下表选择合适的喷嘴，检测油泵压力，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，在零海拔，油温和室温为 20 °C.
推荐的喷嘴:Monarch 类型 R - NS; Delavan 类型 W - A - E
Steinen 类型 H - Q ; Danfoss 类型 H - B
角度 :60°:广泛应用 .
80° : 适合在低温点火时火焰易分离的情况下应
用.
油泵压力 12 bar : 出厂时泵压设定为 12 bar
14 bar : 适合在低温时应用 ;提高火焰稳定性 .
燃烧头设定 :在安装喷嘴时进行 , 同时燃烧筒已移开 . 根据燃烧出力 , 转动
调节杆直到燃烧筒端面达到设定值 , 如图所示 .

任何情况下燃烧头的设定值不要偏离上表参考值太多（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 :
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) 后调整固定风门挡板 (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
挡板 (A) 的运行 .
上表所示的设定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 5) 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.
