IGNITION AND ADJUSTMENT WITH LIQUID
FUEL
• First ignite with gaseous fuel and then later with liquid fuel.
DANGER / ATTENTION
During the ignition and adjustment phase, check that the maxi -
mum and minimum outputs at which the burner is adjusted are
within the working range in order to avoid damage to the system.
• Turn the switch on the control panel to the “O” position (open).
• Turn the fuel change-over switch to the “OIL” position.
• Check that there is water in the boiler and that the gate valves of the
system are open.
• Make sure that the combustion products may be freely vented throu -
gh the boiler and flue dampers.
• Make sure that the mains voltage corresponds to the manufacturer's
requirements and that all electrical connections made at the instal -
lation site are effected properly as illustrated in our wiring diagram.
• Start the fuel supply auxiliary circuit and check for its correct opera -
tion, then set pressure to nearly 0,5÷3 bar if such circuit features a
pressure regulator.
• Remove the vacuum gauge connection plug from the pump and sli-
ghtly open the shut-off valve on the fuel pipe. Let fuel come out until
there are no more air bubbles, then close the shut-off valve. In case
no supply circuit under pressure is available, fill the pump by pouring
fuel into the supply hose.
• Fit a pressure gauge (full scale about 4 bar) to the pump vacuum
gauge connection point to check the pressure value at which the fuel
reaches burner pump. Fuel pressure must remain within 0,5÷3 bar
also when the burner is off.
• Open the shut-off valves placed on the fuel pipes.
• Power on the burner. Verify, by manually pressing the corresponding
remote control switches, that the fan and pump motors rotate in the
correct direction. If necessary, reverse the two cables of the main
line to change the direction of rotation.
• Start operating the burner pump by pressing manually on the remote
control switch until the pressure gauge, which measures the working
pressure of the pump, indicates a slight pressure. The presence of
low pressure in the circuit confirms that filling up has taken place.
• Connect (pos. I) the main switch (1) on the control panel to power
the equipment and close the thermostat line turning the selector (2)
in the "closed" position. If thermostats or pressure switches (safety
and boiler) are closed as well, the operating cycle will start. The equi -
pment turns on. For the regulation of the burner, see “RAPID GUIDE
TO PROGRAMMING” and the specific instruction manual for the
electronic cam supplied with the burner.
• Check that the flame detector is triggered.

SAUTER DIESEL PRESSURE SWITCH
The burner is equipped with a safety pressure switch on the diesel
return circuit. It is installed in series to the air pressure switch and is
enabled only during diesel operation. It intervenes if it detects an incre -
asing diesel pressure equal to the preset value (5 bar).
Every time it occurs, the pressure switch opens its contact simulating
an overpressure of the liquid fuel, determining the lock-out of the flame
control equipment and therefore of the burner.
