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. The combustion space is self-cleaning and
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. 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. The mixer must also be cleaned
from time to time. 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.) Above the boiler burner the ceramic plates and arc are placed. If necessary, clean the area between the
ceramic arc and ceramic plates or the ceramic arc itself. Taking off the ceramic plates is not allowed by
not using the suitable protective equipments.
6.) 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).
7.) 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.
8.) 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.

Instructions for product disposal after its service life
VIADRUS a.s. is a contracting partner of the firm EKO–KOM a. s. with the client number F00120649.
The packages comply with EN 13427.
We recommend to dispose the packages in the following way:
-
plastic foil, cardboard cover, use a salvage point
-
metal strapping tape, use a salvage point
-
wooden base, is designated for a single usage and no longer can be used as a product. Its disposal is
subject to Act. 477/2001 Sb. a 185/2001 Coll.as amended.
Whereas the boiler is constructed from common materials, we recommend to dispose the individual parts as
follows:
-
the heat exchanger (grey cast-iron), use a junk
-
distribution pipes, shells, use a junk.
-
other metal parts, use a junk
-
insulation material ROTAFLEX, through a firm engaged in waste collection and disposal.
In case that the product has lost its serviceability, you can use the back collection service (if this is
introduced). If the originator has declared that it is the waste and it will be handled according to the
legislative provisions valid in the particular country.
