6. Putting into operation – instructions for a contractual service
organization
Putting the furnace into operation can be performed only by a contractual service organization
authorized for performing of this operation.
6.1 Control operation before starting
Before starting the furnace it is needed to check:
a) filling the heat system with water (thermomanometer check) and system tightness.
b) connection to chimney
– this connection can be performed only with consent of a relevant chimney
company according to
Č
SN 73 4201.
6.2 Putting the furnace into operation
1. Performance of fire in the furnace.
2. Setting the furnace on the necessary operating temperature. The recommended temperature of the
output water is 80 °C.
3. Adjustment of the draught controller chainlet length (according to the enclosed draught controller
instruction).
4. Operating of the furnace in the operating condition according to the competent standards.
5. Repeatedly check the furnace tightness.
6. Introduction of the user with servicing.
7. Making a record into the Warranty card.
6.3 Furnace transformation from „solid fuels“ to „gas and liquid fuels“ and
retroactively
In case the user decides according to the situation to perform a transformation of its furnace from solid
fuels to gas or liquid fuels, such transformation can be required only at contractual service company –
organization approved for performing the operation that provides him with performance of such
transformation with an appropriate operating test. Parts for transformation are delivered by the producer.

COKE, ANTHRACITE
The optimal fuel is coke with granularity of 40 – 60 mm but it is possible to burn even coke and
anthracite with granularity of 20 – 40 mm (nut 2). In case of sufficient chimney draught
(15 to 25 Pa) it is possible to burn even non – caking anthracite with granularity of 30 – 50 mm
(nut 1) and 50 – 80 mm (cobbles)
WOOD
To reach the rated power of the furnace it is necessary to keep a maximum humidity at wood of 20 %.
Cleaning of the grate is performed so as the hot fuel would not get through to the ashtray.
The fuel needs to be stored in dry conditions.

Other sorts of wood such as wood clips, wood shavings, sawdust, granules or coal – cakes can be used
as additional fuel. In case of heating with smaller clogs (wood clips, wood shavings, sawdust, granules) it is
necessary to put logs in the bottom part of the burning chamber so as the fuel would not get through to the
ashtray. It is possible to reach smoother burning by further interlaying of the fuel.
These sorts of fuel must have heating power in the range of 12 to 15 MJ.kg
-1
and humidity to 20 % to
prevent from reducing of the mentioned furnace power.
