atmospheric precipitation and dust.
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.
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 G-18 and Astra G-25) and maximal 3 bar
response pressure for the boilers Astra G-31,5, Astra G-40, Astra G-50, Astra G-80 and
Astra G-100. Please consult the chapter 5.
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.
If notice an abnormal boiler operation, stop heating and eliminate damages.
1.11.
6 of this passport.
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:
- 0, 2 MPa (2.0 kg/cm
- 0, 3 MPa (3.0 kg/cm
Astra G- 100.
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,
- 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).
1. SAFETY REQUIREMENTS
Monitor operation of temperature regulation devices and manometer readings.
Kindle the boiler and put the firewood into the boiler only as indicated in section
