the boiler will not operate for a relatively short period of time, than it is
recommended to clean the ash deposited on the easy accessed heating surfaces
of the heat exchanger.
ATTENTION : In case that the boiler will not operate for a long period of
time, then the heat exchanger should be thoroughly cleaned from the deposited
ash. The deposited on the metal surfaces ash acts corrosively on the carbon steel
surfaces, which will lead to a decrease of the lifetime of the boiler’s main
modules – heat exchanger, as well as the burner. It is obligatory to perform
service procedures and preventive observations of the unit by trained service
personal only as well as thorough cleaning at the end of the heating season.
Completing these requirements will ensure long exploitation duration of the
boiler and its high efficiency and reliability. The service check-up of the boiler
as well as thorough ash cleaning allows sustaining the lifetime of the heat
exchanger, decreasing the corrosion and eventual damages. This procedure
should be performed by authorized and certified technician only.

Turning OFF the boiler
The system is turned off by stopping any wood logs charging in the fuel
chamber of the boiler and wait the combustion process get quenched, then
changing the “START” switch into OFF position. After the boiler has cooled
down to ambient temperature, the boiler should be switched off by turning off
the main “POWER” switch. It is recommended to clean the deposited ash
thoroughly of the heat exchanging surfaces of the boiler.

Emergency boiler stop.
In operating process of the boiler emergency situations could arise and the
boiler will go into alarm/failure mode. Overheating situations are detected
by the control board of the boiler and will go into automatic preventive
regimes in order to protect the system.The overheating protection
thermostat (the alarm thermostat) will be activated and the “ALARM”
indicator lamp of the boiler in case of overheating will indicate this state of
the boiler. After the cause of the alarm situation is clarified, take adequate
actions for bringing back the boiler into normal operating conditions.
ATTENTION : in case of emergency situation – boiler overheating, the
emergency thermostat is activated. In this case the boiler should be cooled
down and the reason for such excessive process should be investigated and
preventive measures should be performed. The emergency thermostat
should be manually reset by unscrewing its preventive cap and its stem
should be pressed until the thermostat switches back on (a “click” sound is
