Visually check.

WEEkLY CLEANINg

The following conditions must be ensured in order to execute weekly cleaning of the boiler:
• boILEr MoDE: Boiler in standby mode - Off
• Boiler temperature below 50 °C
It is not possible to execute cleaning if the boiler is not in "OFF mode".
If the boiler is operating with wood, it cannot be stopped (wait until combustion has ended automatically).
Attention: extremely high boiler temperatures can cause burns/injury!
removal of ashes from the upper combustion chamber (see Fig. 3)
• Open the centre door.
• Use the cleaning shovel to push the ashes out from the upper combustion
chamber though the nozzle openings.
Any carbon residues as well as ashes up to approximately 5 cm can remain on the
surface. This will in fact enable rapid ignition of subsequent refuelling and will
protect against premature wear of the ceramic surface.
In order to ensure perfect flow of primary air, it is necessary to remove the ashes
from under the removable steel profiles.
Check system pressure
When the system is cold, the pressure gauge must indicate 1 - 2 bar.
System pressure increases as the water temperature rises. Therefore, in these
conditions, the pressure gauge must indicate between 1.5 and 2.5 bar.
If the system's pressure is too low, it must be increased to the set values by
reloading the boiler.
