APPLIANCE PROTECTION DEVICES

Appliance shut-off conditions
The appliance is protected from malfunctions by means of
internal checks performed by the electronic P.C.B., which
stops the appliance from operating if necessary.
In the event of the appliance being shut off in this manner,
a code appears on the control panel display which refers
to the type of shut-off and the reason behind it.
Switch off the appliance. Make sure the external electric
switch is in the OFF position, shut off the gas valve and
contact a qualified technician.
