heard in this process), screw the cap back. After the boiler is checked and
the cause for overheating is determined and repaired turn the “POWER”
switch ON in order to operate the boiler in normal operation mode.
ATTENTION – the check-up procedure of the boiler, as well as the heating
systems for finding the cause for overheating should be performed by
trained authorized technician. After has been started-up again ,the entire
system, as well as the boiler should be heated up at moderate rate and
should be monitored for any untypical situations, in order to prevent any
alarm mode to rise;
ATTENTION : the stopping of the combustion process of the fuel in the hopper
chamber should not be done by forced quenching (by pouring water and/or thoer
fire extinguishing materials), because this could cause

the heat exchanger and the burner’s nozzle. It is highly recommended to cool
down the heat exchanger by natural cooling down to the ambient temperatures
and after that to perform thorough investigation of the boiler and the control
modules of the system – this should be performed by authorized and trained
technician as well;

Cleaning the ash of the boiler
The cleaning-up of the deposited ash on the heat exchanging surfaces of
the boiler should be performed regularly, which allows efficient operation and
high reliability of the unit.
The cleaning of the ash, deposited on the surfaces of the combustion
chamber of the boiler should be performed before any boiler’s start-up process
(before firing up the fuel) or in case the boiler has not been stopped for couple of
days – the ash should be cleaned on a period of 2-3 days, considering the
thermal capacity and the fuel consumption rate, as well as the properties (mainly
the ash content) of the wood logs.
ATTENTION: at the ash cleaning process small amount of the mineral matter
will be released as fly ash, diluted in the ambient air – it is highly recommended
to have individual protecting wear (for example a mask, which will protect the
human from breathing the small ash particles);
