OPERATING DESCRIPTION
By closing the main switch, if the thermostats are closed, voltage will
reach the command and control equipment and, after a short time, the
burner will start up according to its pre-established program.
The fan motor will then be turned on and, when it starts functioning, it
will bring about a pre -washing of the combustion chamber.
Subsequently, ignition activates and, after three seconds, the safety
valve and the operating (main) valve will open.
The presence of the flame, detected by its control device, permits
continuing and completing ignition.
If there is no flame, the equipment locks-out in safety condition within
3 seconds from gas valve opening (operation and safety).
In “safety lock-out” mode the valves are closed again immediately.
To reset the equipment from its safety position, press the red button
on the equipment.
STARTING UP AND REGULATION
Verify the combustion chamber does not contain gas before any igni -
tion operation.
With a three-phase burner, make sure that the motor rotates in the
correct direction.
• Check that there is water in the boiler and that the gate valves of
the system are open.
Bleed air out of the pipes, if this has not already been done when con -
necting the burner to the gas pipe, taking all necessary precautions
and leaving all doors and windows open.
When the characteristic odour of gas can be smelled, close the cut-off
cock.
Open the union on the pipe near the burner and then open the gas
on/off cocks a little way.
• Make sure that the combustion products may be freely vented
through the boiler and flue dampers.
• Open the combustion air regulator as necessary and open approx.
a third of the passage of air between disk and head.
• Act on the regulators incorporated in the safety and operating valve
in such a way as to obtain the gas delivery deemed to be neces -
sary.
• Deactivate the second stage thermostat to avoid activation and
power the burner by switching the main switch on.
• The burner is therefore activated and carries out the pre-ventilation
phase.
• If the air pressure exceeds that value at which the air pressure
switch has been set, the ignition transformer will be connected and,
subsequently, the gas valves (safety and 1st flame) will be enabled.
• The valves open completely and the gas delivery is limited to the
position at which the flow regulator incorporated in the main opera -
ting valve has been manually regulated.
• Upon first switching on, repeated “lock outs” may occur due to:
• The gas pipeline has not been adequately purged of air and there -
fore the quantity of gas is not sufficient to allow for a stable flame.
• “Lock out” with flame presence could be caused by flame instability
in the ionisation area, due to an incorrect air/gas ratio.
• This can be solved by changing the amount of air and/or gas sup -
plied, so as to find the right ratio.
• This problem could also be caused by an incorrect distribution of
air/gas in the combustion head.
• This can be solved with the combustion head adjustment device by
further closing or opening the air passage between the combustion
head and gas diffuser, through the flame disk adjustment system.
• It may occur that the ionisation current is disturbed by the dischar -
ge current of the ignition transformer (the two currents have a com -
mon path on the burner’s “mass”). Therefore, the burner locks out
due to an insufficient ionisation.
• This can be solved by inverting the input (230V side) of the ignition
transformer (the places of the two wires that give voltage to the
transformer are exchanged).
• A shut down with flame presence could also be caused by the bur -
ner’s casing not being properly “grounded”.
• We must point out that the minimum value of the ionisation current
to ensure the operation of the equipment is shown on the wiring
diagram.
• With the burner running, adjust delivery to the desired value for
“first flame by reading it on the meter.
• The flow rate can be changed using the regulator incorporated in
the valve, as described above.
• Check that combustion occurs correctly by using the appropriate
instruments (CO2 max= about 10% for natural gas - CO max. =
0.1%).
• After this adjustment, switch the burner off and on again a few ti -
mes to check if ignition is correct.
