7.3. Silencing alarms
If an alarm is triggered, follow the procedure described below to
restore normal stove operation:
 Position selector D on the emergency panel (located on the
back of the stove) to OFF for a few seconds until the 3-digit
code identifying the type of alarm disappears. The following
operation also cancels the flashing red LED and the acoustic
alarm signal.
 Return selector D to the REMOTE position to regain
management of the stove operation via the remote control.
 Switch the remote control off and switch it back on again if you
wish to restart the stove.
The stove remains on and operating normally
according to the last mode set only if fault A12
intervened (communication failure between the
remote control and the stove). The stove
automatically exits the alarm mode the first time it
receives a signal from the remote control.
7.3.1. Mechanical seizure of the stove
Mechanical seizure of the stove can be caused by:
 Overheating of the stove structure (“A03”)
 Overheating of the smoke (“A04”)
 While the stove is operating an uncontrolled intake of air or
obstruction in the flue pipe is detected (“A05”)
The seizure is indicated on the display and accompanied by an acoustic
beep.
In this situation the shut down phase is automatically activated.
When this procedure is activated all testing operations to restore the
system will be ineffective. The cause of the seizure is indicated on the
display.
WHAT TO DO:
If the word “A03” appears the stove structure is too hot because the
appliance has operated for too long at maximum power or because it is
poorly ventilated or because the air fans are faulty. When the stove is
cold enough, press button B on the control panel or OFF on the remote
control to cancel alarm A03. Once the alarm has been cancelled, the
stove can be restarted as normal .
If the word “A04” appears the stove automatically shuts down. Leave
the stove to cool down for a few minutes and then restart it.
Check the smoke outlet and the type of pellet used.
If the word “A05” appears the fire door has been open for a long time
or there is some air infiltration (e.g. the smoke blower inspection cap is
missing). If the seizure is not caused by these factors check the smoke
duct and flue pipe and clean them if necessary. (note that this
operation is carried out by a specialised MCZ technician)
Only once the cause of the shutdown has been permanently
remedied can the stove be restarted.
