Mechanical stove block
The following conditions may cause the mechanical stove block:
• Structure overheating (“A03”)
• Smoke overheating (“A04”)
• During stove operation air has entered the combustion chamber or there is an obstruction
in the chimney flue (“A05”)
The block is signalled on the display and with a sound signal. In this situation the shutdown stage is activated automatically.When this
procedure is started, any test operation to restore the system is useless. The display signals the cause of the blockage.
SOLUTIONS:
If “A03” appears: the structure is too hot because the product has been used for too long at the maximum power or due to poor ventilation
or because the air fans are faulty.
When the product is sufficiently cold, press button B on the control panel or OFF on the remote control to cancel alarm A03. Once the
alarm is cancelled, the product can be switched on normally.
If “A04” appears: The stove switches off automatically. Let the stove cool down for a few minutes and then switch it on again. Check the
smoke expulsion and the type of pellets used.
If “A05” appears: the door has been left open for too long or a significant amount of air has entered (e.g. missing smoke fan inspection
cap). If these causes are excluded, check and if necessary clean the smoke duct and flue. (it is recommended that this operation is carried
out by an MCZ qualified technician.
The product can be switched on again only after having eliminated the cause permanently.
