Commissioning - instructions for contractual service organizations
Only professional mounting companies authorized to the performance of this activity may perform commissioning of the boiler.
6.1
Verification activities before commissioning
Before the boiler commissioning it is necessary to check:
1.
Filling of the heating system with water (a check of the thermo-manometer) and tightness of the system.
Connection to the chimney – this connection can be only performed with the agreement of a corresponding chimney-sweep
2.
company (chimney revision).
3.
Functionality of the draught regulator and thermostatic valve.
6.2
Commissioning the boiler
1.
Perform boiler kindling.
Put the boiler to the needed operation temperature. Recommended temperature of output water is 80 °C.
2.
3.
Adjust the draught regulator, including the chain length (according to the attached manual of the draught regulator).
4.
Carry out a check of functionality of the safety device against overheating (of the final-cooling loop or DBV 1 - 02 two-way safety valve).
5.
Operate the boiler in a operational state according to the corresponding standard.
6.
Check repeatedly boiler tightness.
7.
Acquaint the user with servicing.
8.
Perform record into the warranty certificate.

Operating the boiler by user
Wrong servicing and incorrect fuel combustion brings to damaging the product and possible loss of
warranty.
While first kindling of a cold boiler, water condenses in it and streams down by its inner walls. This fogging of the boiler drum will end
as soon as the boiler achieves the operation temperature.
While operating the boiler at temperature lower than 50 °C can occur fogging of the boiler drum, so called low-temperature corrosion,
which shortens the service life of the boiler heat-exchanger. That's why we recommend that you operate the boiler at temperature of
70 °C and higher.
WOOD
To reach the nominal power of the boiler, it is necessary to observe maximum wood humidity of 20 %.
Fuel has to be stored in dry place.

The guarantee of clean and good combustion is the use of only dry and in-natural-state-kept wood.
It is necessary to observe maximum wood humidity of 20 %. As far as wood humidity is higher than 20 %, boiler power is declining.
During combustion of wet wood, water is separated and condensed on walls of the proper boiler drum and chimney body; it causes
increased creation of tar and water steam, which decreases the service life. Insufficient combustion also causes corrosion of cast
iron, so called "metal dusting", when carbon is diffused into material, and - by this - material decomposes to powder (dust). This
process is gradual and long-term. The flow of flue gases with solid particles then causes wearing or erosion of the material from the
surface, and by this the thickness of the section wall gradually attenuates, and this can cause perforation of the boiler drum.
Fuel has to be stored in dry place.
Do not use for combustion: plastics, domestic waste, chemically treated remnants of wood, old paper, wood chips, pilers, waste from
boards pressed from bark or from chipboards.
▶Follow instructions for boiler operation.
▶While operating the boiler, follow recommended operational temperature.
▶Operated the boiler with the approved fuel.
