INSTALLATION AND OPERATION MANUAL
This user manual was compiled following the requirements of 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. SAFETY REQUIREMENTS
1.1. The room where the boiler is to be installed should be ventilated.
1.2. Free inflow of air into the room should be ensured.
1.3. The boiler flue connection with the chimney should be tight. Do not 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 the heating system (including the boiler) (the volume of the
expansion vessel can be calculated according to the standard EN 12828 annex D).
1.5. A safety valve for no more than 3 bar response pressure should be fitted onto the boiler in the heating system (please
see Chapter 5, “Requirements for connection of the boiler to the heating system”).
1.6. Remove the accumulated soot and resin from the boiler flues, as instructed in this manual.
1.7. The room where the boiler is installed should have fire-extinguishing tools: fire extinguishers, sand box, shovel and
other tools.
1.8. Do not place flammable materials on or near the boiler.
1.9. Connect the boiler to the electric system only via a three-pole plug plugged into an adequate three-pole socket with
earthing. Protect connection cable from damages.
1.10. Observe operation of temperature control devices and gauge readings when operating the boiler. In case of faulty
operation of the boiler, stop operation and remove the fault.
1.11. Kindle the boiler and put the firewood into the boiler only as indicated in Chapter 7 of this manual.
1.12. Keep children away from the boiler! The boiler can be serviced only by adults.
1.13. Before kindling the boiler, check if the heating system is filled with water and deaerated.
1.14. The operating pressure in the heating system should not exceed 3 bar.
1.15. The electrical connections are factory tested and the following parameters were confirmed:
• integrity of the protective circuit – electrical resistance of the protective circuit does not exceed 0.1Ω;
• resistance of the electrical insulation – at least 1.0 MΩ;
• resistance of electrical insulation was checked at 50 Hz, 1 000 V voltage.
