FIRST FILLING UP OF PIPELINES
After making sure that protective plastic caps inside the pump fittings
have been removed, proceed as follows :
•
Set the burner switch on “0”.
This operation prevents automatic
connection of the burner.
•
Make sure, in case of a three-phase burner, that the motor
revolves counter-clockwise as seen looking toward the burner
form the pump side. The rotation direction can be discerned also
be looking at the direction of fan rotation through the inspection
window on the back of the scroll. To start the motor, close the
remote control switch manually (pressing on the mobile part) for
a few seconds and watch the direction of the rotation of the fan.
Of it is necessary to reserve the direction of rotation, reverse two
phases on line input terminals counter motor K1.
!
To positively determine the direction of
rotation, wait until the fan turns very slowly
because it is quite easy to misinterpret
direction of rotation.
•
Disconnected, if already connected, the flexible pipes from both
suction and return lines.
•
Dip the end of the suction flexible pipe into a vessel contain-
ing either lubrication oil or diesel oil (do not use low viscosity
products such as diesel fuel, light oil, kerosene. etc).
•
Now press the key (9) on the control panel to start the motor,
followed by the pump. Wait until the pump has drawn 1 or 2 cups
of lubricant, then stop. This will prevent the pump from running
dry and will increase the suction power.
!
Pumps operating at 2800 r.p.m. must not work
dry otherwise they will seize in a very short
time.
•
Now connect the flexible pipes to the suction line and open
all the gate valves fitted on this line and any other similar fuel
cut-off device.
•
Press key 9 again to start the pump which will draw fuel from
the tank. When fuel is seen coming out of the return line (not
yet connected), stop.
!
If the pipe is long, it may be necessary to
bleed the air out through the cap; if the pump
is not fitted with a cap, remove the cap from
the pressure gauge.
•
Connect the return flexible pipe to the return line and open the
valves fitted on this pipe. Now the burner is ready for ignition.
IGNITION AND REGULATION
Before igniting the burner make sure:
•
the feeding line connections to thermostats or pressure switches
are made exactly according to electric diagram of the appliance.
•
There is fuel in the tank and water in the boiler.
•
All the gate valves fitted on the diesel oil suction and return
pipes should be open; the same thing applies to any other fuel
cut-off device.
•
Make sure that discharge of combustion products takes place
freely (boiler and chimney gate valves open).
•
Make certain that the burner head penetrates into the combus-
tion chamber according to the instructions of the boiler manu-
facturer. The burner is equipped with a connecting flange to the
boiler, which glides on the burner head.
•
The nozzles fitted on the burner should match the boil-
er capacity but, if necessary, replace them with others.
Under no circumstances should the amount of delivered fuel be
greater than the maximum amount required by the boiler and
the max. amount permitted for the burner.
To ignite the burner proceed as follows:
!
The burner has a switch to pass manually from
the 1
st
to the 2
nd
stage.
•
To prevent ignition of the second flame: position the 1
st
and 2
nd
stage switch on the printed circuit at its 1
st
stage position for
burners.
•
Adjust the diesel oil for ignition at the 1
st
flame using the specific
cam on the electric servo motor (0002935210).
•
Set the adjustment device in an intermediate position of air
adjustment on the combustion head (see "REGULATION OF
AIR ON THE COMBUSTION HEAD").
•
Close the main circuit breaker and the control box switch.
•
The programmer starts to function and will perform the program
as set, causing connection of the burner component devices
according to the preset program. The burner will start operation
as described in the Chapter “DESCRIPTION OF OPERATION”.
•
When the burner is operating with the 1
st
flame, adjust the
amount of air necessary to ensure an efficient combustion (see
"
AIR ADJUSTMENT ON THE BURNER HEAD". It is better if
the amount of air for the 1
st
flame is slightly reduced in order
to ensure a perfect ignition even in the most critical conditions.
•
After adjusting the air for the 1
st
flame, the burner is stopped, by
cutting off the current from main circuit breaker, and the electrical
circuit that controls insertion of the second flame is closed by
turning the first and second stage switch on the printed circuit
to the 2
nd
stage position.
•
Adjust the air in the amount presumed necessary for the
maximum capacity (2
nd
flame) on the special cam of the electric
servomotor (0002935210).
•
Now connect the burner again; it will start and automatically
switch to the 2
nd
flame according to the preset program.
•
With the burner operating with the 2
nd
flame, adjust the amount
of air necessary to ensure efficient combustion (as illustrated in
item 8)with the airflow necessary to ensure good combustion.
Subsequently check combustion with the special instruments. If
you do not dispose of suitable instruments, check the flame color.
We recommend adjusting the flame to obtain a gentle, light orange
flame, not a smoky red flame or a white flame due to excess air.
The airflow regulator should be in a position that will provide a
percentage of carbon dioxide (CO
2
) in the smoke, varying from
min. 10% to max. 13% with a smoke number not exceeding 2
(Bacharach scale).
