IGNITION AND ADJUSTMENT WITH LIQUID
FUEL
• Make sure that there is fuel in the tank.
• Check that the nozzles fitted on the burner are suitable for the boiler
capacity. If necessary, replace them with suitable ones.
• The quantity of fuel delivered must not exceed the maximum amount
required by the boiler and the maximum amount allowed for the bur -
ner.
• Make sure that motors (fan and pump) turn in the right direction.
• 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.
• Turn the switch (1) on the control panel to the “O” position (open).
• Turn the fuel change-over switch to the “OIL” position.
• 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.
• Turn the main switch (1) to position "I" (closed) to supply power to
the equipment.
• Close the thermostatic line by setting switch (2) to position "I" (clo -
sed).
• If thermostats or pressure switches (safety and boiler) are closed as
well, the burner operating cycle will start.
• To adjust the minimum and maximum burner flow rate, refer to the
nozzle return flow/pressure diagram.
• Keep an indicative value of O2 between 3,5 - 4 %.
