Heating boilers are transported packed under the manufacturer's documentation, protected from atmospheric

The transporter should ensure the quality of product transportation and protect from damages.

The vendor (manufacturer) does not accept claims for production damaged during transportation.

The BUYER should lay claims to the transporter for the product damaged during transportation.

The BUYER (user) should follow all requirements of this guidebook during transportation, storage and

exploitation, otherwise he loses the vendor's (manufacturer's) guarantees.

This instruction will enable accordance with the requirements according to LST EN 12171 "Heating

systems in buildings - Procedure for the preparation of documents for operation, maintenance and use -

Heating systems not requiring a trained operator".

1.1. The room where the boiler is to be installed should be ventilated.

1.2. The air should freely access the room.

1.3. The boiler flue connection with the chimney should be tight. Don't heat up the boiler with leaking

flue connections!

1.4. The boiler should be installed in a closed heating system with a closed (membranous)

expansion vessel, the volume of which should be no less than 10% of the total volume of a heating

system (including the boiler) (the volume of the expansion vessel can be calculated according to the

standard EN 12828 annex D).

1.5. Safety valve for no more than 2 bar response pressure should be installed at the boiler in the

heating system for the boilers Astra H-25 ES and Astra H-31,5 ES and maximal 2,5 bar response

pressure for the boilers Astra H-45 ES. Please consult the chapter 4.

1.6. Clean boiler flues from smoke and pitch scurf, as indicated in this passport. The chimney

should be cleaned as required by fire prevention regulations.

1.7. The room where the boiler is installed should have fire-extinguishing tools: fire-extinguishers,

sand box, shovel and other tools.

1.8. Don't put flammable materials on or near the boiler.

1.9. Connect the boiler to the electric system only by a three-pole plug plugged into an adequate

three-pole socket with earthling. Protect connection cable from damages.

1.10.

an abnormal boiler operation, stop heating and eliminate damages.

1.11.

this manual.

1.12. Keep children away from the boiler! Only adults can serve the boiler.

1.13. Before kindling the boiler, check, if the heating system is filled up with water and aired.

1.14. Operating pressure in the heating system should not exceed:

- 2 bar – for the boilers Astra H-25 ES, Astra H-31,5 ES,

- 2,5 bar – for the boilers Astra H-45 ES.

1.15. The electrical connections of the boiler are tested:

- evenness of the protective chain – electric resistance of the protective chain does not exceed

0,1 ,

- the minimal resistance of the electric insulation is 1,0 M ,

- the resistance of the electric insulation is checked using 50 Hz, 1000V.

Heating boilers are designed for heating of dwelling houses, public, industrial and similar purpose

buildings where water-heating systems are installed. Boilers are fired only with wood (firewood) or (saw dust,

peat, chaff, etc.) briquettes. It is recommended to fire dry (20% moisture content) wood. It is possible to fire fine

wood waste and saw dust in small quantities (to 10%), mixing them with firewood. Control and regulation

equipment installed in the boilers automatically maintains the set heat carrier (water) temperature, ensures cost-

efficient operation of the boilers, and safe exploitation.

The boilers of this type are constructed for wood firing with a partial gas generation. In the upper

combustion chamber of the boiler, gas is extricated (generated) from the burning firewood and burned in the

lower chamber. Intensity of gas generation and its combustion is regulated by the frequency and duration of air

inlet into combustion chambers.

Advantages of the boilers:

Gas generation from firewood ensures a high effective operation coefficient.

Boiler is equipped with the excess heat distribution system (serpentine of the emergency

cooling).

precipitation and dust.
