Fault diagnosis and repair
In the event of a malfunction, first check
that the prerequisites for correct
operation are fu llfilled:
1. Is the system connected to the
power supply?
2. Is there any gas pressure?
3. Is the gas shut-off valve open?
4. Are all control and safety devices,
such as the boiler thermostat, low
Maintenance
Annual check
The burner (combustion head, electrodes,
etc.) must be checked regularly by an au-
thorized technician, once or twice a year,
depending on how much it is used. Before
proceeding with the maintenance check-
up on the burner, it is advisable to check
the general condition of the burner and
take the following steps:
Disconnect the burner (remove the plug).
- Close the gas shut-off cock.
- Remove the cover from the burner,
clean the fan and air intake.
- Clean the combustion head and check
the position of the electrodes.
- Re-install the parts.
- Check the seal on the gas connetors.
- Check the state of the flue.
- Start the burner.
- Check the combustion parameters
Before taking any action check:
- That there is power in the circuit and
the burner is connected;
- That the gas pressure is right and
the gas shut-off cock is open;
- That the control systems are pro- perly
connected. If all these conditions have
been satisfied, start the burner by pres-
sing the reset button.
- Check the burner cycle.
If the burner fails to start:
check the switch, the thermostats, the
motor and the gas pressure.

water level detector, limit switch,

If the malfunction persists, use the
following table.
It is not permitted to repair any
components relevant to safety. These
components must be replaced by parts
with the same order number.
If the burner proceeds with preventila-
tion but cuts out at the end of the cycle:
- Check the air pressure and the fan.
- Check the air pressure switch.
If the burner proceeds with preventila-
tion but does not light:
- Check the installation and position of the
electrodes.
- Check the ignition cable.
- Check the ignition transformer.
- Check the safety device.
If the burner lights but cuts out after the
safety interval:
- Check that the phase and neutral wires
are connected correctly.
- Check the gas solenoid valve.
- Check the position and connection of the
detector electrode.
- Check the detector electrode. Check the
safety device.
If the burner lights but cuts out after
operating for a few minutes:
- Check the pressure regulator and gas fil-
ter.
- Check the gas pressure with a pressure
gauge.
- Check the detector value (at least 3 µA).
