Putting into operation – instructions for a contractual service organization
Putting the boiler 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 boiler 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 boiler into operation
1.
Performance of fire in the boiler.
2.
Setting the boiler 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 boiler in the operating condition according to the competent standards.
5.
Repeatedly check the boiler tightness.
6.
Introduction of the user with servicing.
7.
Making a record into the Warranty card.
6.3
Boiler 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 boiler 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.

User’s boiler service
Incorrect operation and improper combustion of fuel leads to damage to the product.
During the first ignition of the cold boiler, water condenses therein and then flows down its inner walls. This condensation of the
boiler body ends when the boiler reaches operating temperature.
During the operation of the boiler at the temperature lower than 60°C, condensing of water on the boiler body or the so called low
temperature corrosion can take, which shortens the life of the boiler exchanger. Therefore we recommend to operate the boiler at
60°C and higher.
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 (0,15 to 0,25 mbar) it is possible to burn even non – caking anthracite with granularity of 30 – 50 mm
(nut 1) and 50 – 80 mm (cobbles)
WOOD
Guarantee of clean and good combustion is to use only dry and wood in the natural state.
It is necessary to keep the wood max. humidity 20%. If the humidity is higher than 20%, output of the boiler decreases. Combustion of
the damp wood releases water which condenses on the walls of the boiler and chimney body, this leads to an increased formation of
tar and water vapor, which reduces the life of the heat exchanger. Furthermore, improper combustion causes corrosion of cast iron
called "Metal dusting", which leads to carbon diffusion into the material, and thus disintegration of the material to a powder (dust).
This process is gradual and long-term. Flue gas stream with solid particles then causes abrasion or erosion of material from the
surface, thereby gradually thinning the wall thickness of the elements, and this can cause perforation of the boiler body.
Fuel must be stored in a dry place.
For heating, do not use plastics, household waste, chemically treated wood residues, waste paper, wood chips, brushwood, garbage
from boards pressed from the bark or chipboards.
▶
Follow the instructions for operating the boiler.
▶
When operating the boiler follow the recommended operating temperature.
▶
Operate the boiler with an approved fuel.

Cleaning of the grate is performed so as the hot fuel would not get through to the ashtray.
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
boiler power.
