INSTALLATION AND OPERATION MANUAL

its upper supports. Then the tool can be removed and the next plate can be installed in a similar way.

Turbulence plates decrease the temperature of the exhaust smoke. The boiler can be operated without the plates, but then 

greater losses of heat through the chimney will occur.

3. InTenDeD Use

The heating boiler is designed for the heating of residential and public buildings, manufacturing shops and other buildings 

where a closed heating system has been installed. Control and regulation devices are installed in the boiler, which automatically 
maintain the set water temperature, ensure economically efficient usage of the boiler and safe operation.

Boilers of this type are designed to burn wood, partially generating gases. Gas is extricated (generated) from the burning 

firewood in the upper combustion chamber of the boiler and burned in the lower chamber. The intensity of gas generation 
and combustion is regulated by the frequency and duration of air inflow into the combustion chambers.

Advantages of the boiler are the following:
• gas generating combustion ensures effective burning of wood and a high efficiency coefficient since the burning process 

takes place at a high temperature of 900°C;

• the heat output of the boiler can be regulated within the range of 40-100%. The boiler is automatically controlled using an electronic 

regulator, by switching the ventilator inflowing into the combustion chambers off or on, or by regulating the speed of its rotation;

• the combustion period of one fuel load is long due to the large volume of the fuel chamber;
• complete fuel combustion ensures cost-efficient fuel usage;
• the turbulence plates installed in the flue of the boiler enhance heat exchange in the boiler and reduce the temperature 

of the smoke in the chimney;

• it is sufficient to remove the ashes 1-2 times per week.

The heating boiler is to be transported and packaged in accordance with the documentation of the manufacturer, protected 

from precipitation and dust. It can be transported only in vertical position, fastened to avoid sliding and falling. If the boiler 
is transported in other than vertical position, decorative surfaces may be damaged, cladding battered, control and regulation 
equipment broken, built-in ceramic inserts may fall down and splinter. The heating boiler should be carefully loaded, unloaded 
and transported, without any significant impact.

The boiler should also be stored in a vertical position. It is not allowed to put one boiler on top of another, as a packaging 

frame is not designed for this purpose. The boiler should be stored in a closed room protected from precipitation. The air 
humidity of the room should not exceed 80%, in order to avoid condensate forming on the surfaces of the boiler. Storage 
temperature may vary from -40°C to +60°C.

If the boiler was transported or stored in minus temperatures, then before it is kindled, it should be kept in plus temperature 

for no less than 2 hours.

After the heating boiler is delivered to the site, take off the packing frame and polyethylene film, unscrew boiler bolts and, 

fastening to the packaging base, remove the boiler from the packaging base.

 open the doors of the boiler and check if all elements listed in a delivery kit are included.

The delivery kit consists of the following: boiler - 1 pc.; poker - 1 pc.; scraper - 1 pc.; ventilator - 1 pc.; operation manual - 1 

pc.; support legs - 4 pcs.

Check if painted surfaces have not been damaged during transportation, if the components are not bent and if control and 

regulation equipment is intact. In case you notice any inadequacies, present your claims to the vendor company.
