FIRST FILLING UP OF PIPELINES

After making sure that the protective plastic caps inside the pump
fittings have been removed, proceed as follows:
• Set the burner switch on "O" to prevent an automatic connection
of the burner.
• Make sure, in case of a three-phase burner, that the motor
revolves anti-clockwise when watching it from the pump side.
The rotation direction can be determined also 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. If it is necessary
to change the rotation direction, reverse the two phases to the
motor contactor terminals K1.
To determine the rotation direction, wait until the fan turns
very slowly, because it is quite easy to misinterpret the
rotation direction.
• Disconnected, if already connected, the flexible pipes from both
suction and return lines.
• Dip the end of the suction flexible pipe into a vessel containing
either lubrication oil or fuel oil (do not use low viscosity products
such as gas-oil, light oil, kerosene. etc).
• Now press key (9) on the control panel to start the motor and the
pump. Wait until the pump has sucked in an amount of lubricant
equal to 1 or 2 glassfuls, then stop. This operation will prevent
the pump from operating dry and will increase the suction power.
Pump operating at 2800 r.p.m. must not work dry otherwise
they will jam (seizure) within 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 suck fuel from
the tank. When fuel is seen coming out of the return pipe (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 pressure gauge connector cap.
• Connect the flexible return hose to the pipe and open any gate
valves fitted on this pipe. The burner is now ready to start up.

IGNITION AND REGULATION

Before starting up the burner make sure that:
• The right type of fuel has been selected.
• Feeding line connections to thermostats or pressure switches
are made exactly according to electric diagram of the control box.
• There is fuel oil in the tank and water in the boiler.
• All the gate valves fitted on the fuel 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 sure that the combustion head penetrates the furnace to
the extent requested by the boiler manufacturer. Make sure the
air shut-off device on the combustion head is in the right position
to ensure a correct combustion; the air passage between disk
and head should be significantly reduced in case of reduced
fuel delivery. When fuel delivery is high, the air passage should
be consequently increased, see chapter "COMBUSTION HEAD
ADJUSTMENT".
• The nozzles fitted on the burner must be suitable for the
boiler capacity. If necessary, replace them with suitable ones.
In no case should the quantity of fuel delivered exceed the
maximum amount required by the boiler and the maximum
amount allowed for the burner.
To start the burner proceed as follows:
The burners have a switch to pass manually from the 1st to
the 2nd stage.
• To prevent ignition of the second flame, turn the 1
switch on the printed circuit to the 1
• Adjust the air in the amount presumed to be necessary for the
1 stage ignition using the special cam of the air adjustment
st
servomotor.
• Set the air adjustment device on the combustion head in
an intermediate position (see "AIR ADJUSTMENT ON THE
COMBUSTION HEAD").
• Activate the main switch and the control panel switch.
• The programmer starts to operate and activates the burner
devices according to the pre-set program. The burner will start
operation as described in the Chapter "DESCRIPTION OF
OPERATION".
• When the burner is operating in the 1
of air necessary to ensure an efficient combustion, see "AIR
ADJUSTMENT ON THE BURNER HEAD" and 000293 for 1
flame diesel oil adjustment cam.
