BOILER’S LOCK OUT RED LAMP [7]
The red lamp can be off, flashing and on.
OFF: the functioning of the boiler is correct.
FLASHING:
— One of the internal sensors of the boiler has been damaged. Call a Qualified Techni-
cian for repairing.
ON - it signals problems that can be normally solved by the user:
— The boiler has been just installed, or works have been made on the gas pipes.
It is normal that the boiler goes repeatedly in Lock Out when the Inlet Gas is mixed
with air. This impedes the correct ignition and then provokes the Lock out. In the
conditions described above, it is necessary to repeat more times the ignition of the
boiler turning the SUMMER/WINTER Selector in the Unlock
Position until the
red lamp turns off.
— The water pressure, shown by the gauge in the control panel, is not sufficient (0,5 bar
or lower).
Restore the correct pressure (optimal pressure: 1÷1,5 bar at cold system) opening
the inlet tap (the action is described before). Do not restore the pressure with hot
system, because when the system gets cold the pressure decreases.
Consider that the pressure, in normal conditions, should not decrease.
If this hap-
pens, there is probably a loss in the heating system. Sometimes the loss is so small
that it doesn’t leave evident signs, but with the progress of the time it can cause the
decreasing of the pressure.
Also the opening of the Manual Radiator Outlet taps (intentional or unintentional)
makes the pressure decrease. Check that this doesn’t happen.
— the boiler has an overheating and the Safety Thermostat has triggered;
Turn the SUMMER/WINTER Selector in the central Unlock
Position until the
red lamp turns off (or eventually for a longer period to make the boiler cool), then
bring again the selector in the desired position (Summer or Winter ). If the
Lock Out takes place again call the Service Centre.
— the burner hasn’t regularly switched on or the flame has suddenly turned off; incor-
rect combustion.
Restore the service turning the SUMMER/WINTER selector in the Unlock
Position
until the red lamp turns off. In case of frequent Locks:
• Call a technician to check the combustion and verify that the burner is clean and in
good conditions;
In “SE” models with Sealed Combustion Chamber:
• Check that the Inlet/Outlet Ducts and the respective terminals are clean and in good
condition, and that there are no leaks. During the Installation Process it is necessary
