IGNITION AND ADJUSTMENT
WITH LIQUID FUEL
It is recommended to first make the ignition with the liquid fuel as
the delivery is conditioned by the nozzle.
Then to regulate the gas operate the pressure regulator on the
gas train.
• Turn the switch on the control panel to the “O” position (open).
• Turn the fuel change-over switch to the “OIL” position.
• Check that thee voltage on the mains meets the manufacturer
requirements and that all electrical connections made at the in-
stallation site are performed properly as illustrated in our wiring
diagram.
• Verify that the discharge of combustion fumes through the boiler
shutters, flue shutters can take place freely.
• Check that there is water in the boiler and that the gate valves
of the system are open.
Check that all the gate valves fitted on the fuel suction and return
pipes are open; the same applies to any other fuel shut-off devi-
ces.
• Start the fuel supply auxiliary circuit and check for its correct
operation, 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
slightly 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 va-
cuum gauge connection point to check the pressure value at
which the fuel reaches burner pump. Fuel pressure must re-
main 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 the burner pump by manually pressing the relevant remote
control switch until the pump pressure gauge detects a slight
pressure. A slight pressure in the circuit indicates that it has
been filled up.
• 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 equipment 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.
