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 (4).
Fix the flange (1) to the boiler door (3) using screws (5) and (if necessary) the nuts (2) interposing the
insulating gasket (4), (see Fig. 2).
After installation ensure that burner is lightly inclined as in Fig. 4.
3.2 FUEL SUPPLY
T he b u r n e r i s d es ig n e d t o a l l o w e n t r y o f t h e o il s u p pl y p i p e s o n e i t h er si d e .
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. 5).

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. 7 it is sufficient to loosen the suc tion gauge
connection (5, Fig. 6) and wait until oil flows out.
On the systems in Fig. 8 and 9 start the burner and wait for the priming.
Should lock-out occur prior to the arrival of the fuel, await at least 20 seconds be-
fore 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. 9) 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.

The 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. 6).
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 EN 267 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.
T h e v al u es s h o w n i n t h e t a b l e a r e m e a s ur e d o n a C EN b o i le r ( as p e r E N 2 6 7) .
They refer to 12.5% CO2 at sea level and with gas 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 3.00 - 3.50 GPH nozzles it is advisable to use
full cones.
TO FIT NOZZLE CARRY OUT THE FOLLOW-
ING ACTIONS (See Fig. 11):
Remove nozzle-holder assembly (1) after loos-
ing screws (2) and nut (3), remove the small
cables (4) from the flame control and the flame
sensor (6).
Withdraw the small cables (4) from the elec-
trodes, remove the diffuser disc-holder assembly
(10) from the nozzle-holder assembly (1) after
loosing screw (3, Fig. 12, page 7).
Screw the nozzle (11) correctly and tighten it as
shown in the figure.
ATTENTION
During the reassembly of the nozzle-holder assem-
bly screw the nut (3) as shown in the figure below.

4.5 COMBUSTION HEAD SETTING (see Fig. 11, page 6)
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 2.25 GPH at 12 bar.
The set-point 3 of the regulating rod (9) is at the same level with the outside plane of the nozzle-holder assem-
bly (1) as shown in the schedule.
4.6 AIR DAMPER ADJUSTMENT (see Fig. 11, page 6)
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.

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 flame sensor, (7, Fig. 1, page 1).
Check for correct fuel consumption.
Replace the nozzle (see Fig. 11, 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; Content of CO2 ( % ); Content of CO (ppm);
Smoke value according to opacity smokes index according to Bacharach scale.
