: Removal of the ceramic stones from the lower combustion chamber.
The ceramic stones can be removed from the lower combustion chamber during
annual maintenance.
After cleaning, they must be pushed back against the rear wall of the lower
combustion chamber of the boiler.
(Fig. 9)
ANNUAL CLEANING
The following conditions must be ensured in order to execute annual cleaning of the boiler:
•
BOILER MODE:
Boiler in standby mode - OFF
•
Boiler temperature below 30 °C
•
No voltage on the boiler - Turn the main switch from
I
to
O
, to disconnect the mains power supply.
IT IS NOT POSSIBLE TO EXECUTE CLEANING IF THE BOILER IS NOT IN “STANDBY MODE - OFF”.
If the boiler is operating, it cannot be stopped (wait until combustion has ended automatically!).
ATTENTION
: EXTREMELY HIGH BOILER TEMPERATURES CAN CAUSE BURNS/INJURY!
ATTENTION
IF THE MAIN SWITCH IS NOT ENABLED (BOILER DISCONNECTED FROM POWER SUPPLY), ELECTRICAL SHOCKS
ARE STILL POSSIBLE ON LIVE PARTS.
On completion of the cleaning operations, the turbulators are reinstalled and secured by following the sequence in reverse order.
To facilitate assembly and disassembly of the turbulators, it is possible to simultaneously remove the cleaning lever on the side of the boiler.
Depending on the boiler mode, the turbolators are coupled (Fig. 7) or screwed on (Fig. 8).
The turbulators must be removed upwards from the pipes.
Then use the cleaning tools to free the pipes from dirt particles. These residues fall into the lower combustion chamber, from where they can
be removed.
The collection drawer above the pipes must be cleaned with a vacuum cleaner.
CLEANING THE HEAT EXCHANGER PIPES
The service door is situated on the upper part of the boiler next to the smoke suction fan.
It can be opened from the integrated handle. (see Fig. 4)
The wing nuts must then be removed from the isolating panel. (Fig. 5)
The panel is removed upwards from the handle.
This will expose the heat exchanger pipes and turbulators. (Fig. 6)
