8-SAFETY DEVICES AND ALARMS
BLOCKED PRODUCT
The following may cause the product to be mechanically blocked:
• structure overheating (“A03”).
• Smoke overheating (“A04”).
• During product operation, air that has not been controlled has entered the combustion chamber or the chimney is clogged (“A05”).
• Boiler overheating (“A18”)
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 to cancel alarm A03. Once the alarm is deleted, the product can
be switched on.
If “A04” appears, the product will shutdown automatically, let it cool down for a few minutes and then switch it on again.
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 chimney.
If “A18” appears: the stove switches off due to the boiler overheating. This can be caused by water not circulating (pump blocked or faulty).
Check the circulation pump is working properly and then cancel the alarm and switch the stove on again.
Only after having eliminated the cause permanently can the product be switched on again.
