Putting into operation – instructions for contractual service organization
Putting into operation can be performed only by specialized installation companies authorized to carry out this activity.
6.1
Verification activities before start-up
Before the boiler commissioning it is necessary to check:
1.
Filling the heating system with water (check thermomanometer) and tightness of the system.
2.
Connection to the chimney – this connection can be made only with the agreement of a chimney firm (chimney revision).
In case the chimney doesn’t comply with the requirements for minimum chimney draught, specified in tables No. 2, 4 and 5
(0,18 – 0,25 mbar depending of fuel type), we recommend using an exhaust electric fan.
3.
Functionality of the draught regulator and the thermostatic valve.
6.2
Putting into operation
1.
Fire the boiler.
2.
Bring the boiler to the necessary operating temperature. The recommended output water temperature is 80 °C.
3.
Adjust the draught regulator including the chain length (according to the enclosed draught regulator manual).
4.
Check the functionality of the safety equipment against overheating (after-cooling loop or two-way safety valve DBV 1 - 02).
5.
Operate the boiler in operating condition according to relevant standards.
6.
Check again the boiler tightness.
7.
Familiarize users with the boiler operation.
8.
Make a record to the warranty card.

Boiler operation by user
Incorrect operation and improper combustion of fuel leads to damage to the product.
During the first firing of the cold boiler, water condenses therein, which flows down the inner walls. The condensation of water on the
boiler stops once the boiler reaches the operating temperature.
When operating the boiler at the temperature lower than 60 °C, water can condense on the boiler drum, that can lead to the so called
low-temperature corrosion, which shortens the life of the boiler exchanger. Therefore we recommend to operate the boiler at 60 °C
and higher.
LIGNITE
The most suitable fuel is lignite with the grain size of 20-40 mm. Burning time at rated output is 4 hours.
HARD COAL
The most suitable fuel is hard coal with the grain size of 20-40 mm. Burning time at rated output is 4 hours.
WOOD
To achieve the rated output of the boiler, wood moisture content must be max. 20%.
Fuel must be stored in a dry place.

Guarantee of the clean and good combustion is using only dry natural wood.
Wood moisture content must be max. 20%. If the wood moisture content is higher than 20%, the boiler output declines. Damp wood
burning releases water which condenses on the walls of the boiler and the chimney, this leads to an increased formation of tar and
water vapour, which reduces the life of the heat exchanger. Furthermore, improper combustion causes corrosion of cast iron, the so
called "metal dusting", which leads to carbon diffusion into the material, and thereby the degradation of the material to powder (dust).
This process is gradual and prolonged. The flue gas stream with solid particles then causes abrasion or erosion of the material from
the surface, which leads to gradual thinning of the section walls, and this may 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, waste
from pressed sheets of bark or chipboard.
▶
Follow the instructions for the boiler operation.
▶
When operating the boiler follow the recommended operating temperature.
▶
When operating the boiler, use only approved fuel.
