that non typical noise is heard from the fan. Clean of the deposited ash,
tars and other depositions from the turbine of the boiler;
ATTENTION : regular cleaning of the ash residue, deposited on the heat
exchanging surfaces of the boiler will ensure long-life reliable exploitation
period, economic and efficient performance of the unit;

Safety and unexpected risks
Risks could arise at the exploitation of the boiler:
The wood gasification hot water boiler of series “Pyrotherm” is designed
according to the safety requirements of the operating European standards and
norms. However safety and unexpected risks could arise in situations like
following:
•
Hot water boiler of series “Pyrotherm” is operating incorrectly;
•
The boiler is installed by unauthorized/unqualified personal;
•
The safety instructions, described in this manual are not followed and
fulfilled;
Unexpected risks:
The boiler is designed and produced according to the requirements of the
operating EU safety norms. However, in spite of that possible risks are
considered as a result of the operating process of the boiler, it is possible to arise
risks as follows:
•
Cauterization risks, caused by high temperatures, as a result of the
combustion process in the combustion chamber and/or direct access to the
front door of the combustion chamber, at manual cleaning processes of the
surfaces and combustion chamber, or ash residue cleaning, accumulated in
the combustion chamber or any unburned fuel material or smoldering one;
•
Electrical shock risks at indirect contact. The boiler is connected to the
power circuit and its operating elements are separated in specialized
electric control box, equipped with required protective and short-circuit
preventive fuse. It is obligatory to perform system ground connection by
authorized personal/technician;
•
Fingers injuring risks at opening/closing the doors/lids of the boiler at
maintenance and cleaning process of the unit. It is recommended to use
appropriate individual resources for self-protection;
•
Suffocation risks due to flue gas uncontrolled emissions in the boiler’s
room, in case when the chimney draught is insufficient, in case that the
