FIRST FILLING UP OF PIPELINES

After checking that the 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. This operation prevents the burner
from activating automatically.
• If the burner is three-phase, make sure that the motor rotates
in an anti-clockwise direction, by observing the burner from the
pump side. This can be checked also by looking at the sense
of rotation of the fan through the inspection hole situated on
the back of the scroll. To start up the motor, close the remote
control switch manually (by pressing on the mobile part) for a
few seconds and watch the sense of rotation of the fan. Of it is
necessary to reserve the direction of rotation, invert 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 possible to
misinterpret direction of rotation.
• Detach, if already attached, the flexible hoses from the intake
and return pipes.
• Dip the end of the flexible intake hose in a tin containing either
lubricant or fuel oil (do not use low-viscosity products such as
diesel, petrol, kerosene, etc.).
• Now press on the mobile part of the motor remote control switch
in order to start up the motor and therefore 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.
• In the case of mono-phase power supply, switch off the master
switch and boiler and safety thermostats and then start up
the motor and ignition transformer. On inserting the solenoid
expose the photoresistor to a light source so that the burner
does not "lock-out". When the piping is filled (when fuel comes
out of the nozzle) stop the burner and put the photoresistor
back in its place.
Pump operating at 2800 r.p.m. must not work dry otherwise
they will jam (seizure) within a very short time.
• Attach the flexible hose to the intake pipe and open any gate
valves fitted on this pipe and any other shut-off element on the
fuel pipes.
• Run the pump again as previous points in the case of monophase
and three-phase burners. The pump will extract the 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 breather cap,
remove the cap from the pressure test point.
• 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, make sure that:
• Connections to the supply line, to thermostats or pressure
switches, have been made according to the electrical diagram
of the equipment.
• There is fuel oil in the tank and water in the boiler.
• All the gate valves fitted on the fuel oil intake and return pipes
are open, as well as any other shut-off element on the fuel pipes.
• The discharge of combustion products can take place freely
(boiler and chimney lock-gates should be open).
• Make sure that the burner head enters the combustion chamber
according to the boiler manufacturer's instructions. The burner,
to meet these requirements, is equipped with a boiler mounting
flange which slides along the combustion head.
• 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.
For the ignition proceed as follows:
The burners DACA version are provided with switch needed
to change from 1st to 2nd stage.
• Avoid the operation of the second stage: position the 1st and 2nd
stage switch of the electrical panel at its 1st stage position. If the
burner does not have 1st and 2nd stage, remove any thermostat
connection to prevent insertion of 2nd stage.
• Slightly open the air regulator and let in an amount of

to adjust with the hydraulic jack see card 0002935420, to adjust
with servomotor see card 0002935210. Set the adjustment
device in an intermediate position of air adjustment on the
combustion head (see "Regulation of air on the combustion
head").
• Turn on the main switch and the one on the control panel, if
provided.
• The small motor of the cyclic relay which will start to rotate
causing the connection of the burner component devices
according to the preset program. The equipment turns on as
described in the chapter "Operation Description".
• When the burner is operating in the first stage, adjust the
air to ensure a good combustion as described at point 2. We
recommend keeping the air quantity at a low level when working
in the first stage output to ensure a perfect ignition even in the
most difficult conditions.
• After adjusting the 1st stage air the burner stops disconnecting
the current from the main switch, the electric circuit commanding
the second stage activation closes moving the 1st and 2nd switch
on the electrical panel to the 2nd stage position If the electrical
panel does not have 1st and 2nd stage switch connect the
terminals of the 2nd stage thermostat on the boiler terminal block.
