Having finished the heating season the boiler including the smoke flue must be thoroughly
cleaned. The boiler must be kept clean and dry.
•
It is forbidden to interfere with construction and boiler electric installation.
•
In case the two-way safety device has responded to refill with water not conforming to
Č SN 07 7401 it is necessary to treat the water in the system so that it again conforms to this
standard.
•
It is necessary to install a safety valve for maximum overpressure of 250 kPa (2,5 bar) on the
system and its dimension must correspond to the rated boiler output. The safety valve must be
located directly behind the boiler. Any stop valve must not be located between the safety valve
and boiler. If you have any questions, please contact our contractual assembly firm and service
organizations.
•
WARNING! A poor quality of fuel can markedly negatively affect the boiler output and emission
parameters
•
During assembly, installation and operation of the appliance it is necessary to comply with
standards that apply in the relevant country of destination.
If you fail to meet these conditions you cannot requisite the guarantee repairs.
8. Maintenance
1.) It is necessary to refill the fuel in time. When only a small volume of fuel is left in the reservoir it must be
refilled immediately. Mind out that you close properly the fuel reservoir cover afterwards!
2.) If the boiler is properly adjusted the fuel is fully burnt out once it has reached the edges of the
combustion grate. The ashes and cinder fall into the ash tray. In time of an average output the ash-tray
must be cleaned every other day (the protective gloves must be used). Occasionally a piece of cinder
sticks between the edge of combustion grate and the boiler wall. Then it must be removed by means of
a poker.
3.) In time of a continuous operation it is recommended to clean once a month the convection surface of
boiler drum. (lamellas, combustion chamber side walls etc.). The heat transfer surfaces are getting
choked which can substantially influence the heat transfer thus the boiler efficiency. These areas are
accessible after dismantling the cover of the smoke adapter. When burning the pellets the fuel gets
agglomerated in the retort. Therefore this cake must be mechanically removed once a month
otherwise the screw movement stops. It is necessary to clean the mixer. The mixer choke deteriorates
the combustion air flow into the burner. Minimally one hour before the cleaning process the boiler must
de shut down.
4.) Then we recommend to do occasionally an external cleaning of the engine with the tansmission and
fan. (The operator must not remove the cover from ventilator neither interfere in any other way
with these units. It can only be done by a qualified service worker.) A dry brush is to be used for
cleaning. The boiler during the cleaning process must be disconnected from the electricity supply.
5.) If the pieces of stone, metal or wood occur in the fuel the feeding screw, it can get blocked. If this
situation happens and the engine is overheated and stopped the boiler must be switched off and the
obstacle removed.
CAUTION: Before you carry out this operation you must make sure that the boiler is
disconnected from the electricity supply(it is unplugged).
6.) Because a slight overpressure develops in the combustion chamber with ventilator in operation it is
necessary to mind a perfect tightness of boiler (the combustion chamber door, ash-pan door, mixer
cleaning opening, fuel reservoir cover etc.) The fuel reservoir tightness is given first of all by closing its
cover properly by means of a pivot cap and undamaged rubber sealing of the seating faces.
7.) If there occurs the emergency condition (the electric supply voltage failure for a longer time, ect.) and the
fuel burns to the fuel hopper, owing to the temperature increase the valve TS 130 (BVTS, STS20)
responds and the fuel is smothered.
8.) Regularly once a month clean the boiler walls inside the fireplace, boiler smoke draughts and smoke
adapter (by means of a brush at cooled down boiler the temperature of which does not exceed 40
o
C).
The cleaning cover in the lower part of the smoke adapter serves for ash removal. When dismantling the
cleaning cover the screw of securing swivel must be loosened to avoid its damage. After the smoke
adapter has been cleaned we mount back the cleaning cover whereas we are particular about the
tightness between the cleaning cover and smoke adapter.
