Dear customer,
We thank you that you have bought a
HERCULES E68
boiler, thus having shown your confidence in VIADRUS brand.
To get you accustom from the very beginning to correct handling with your new boiler, please firstly read this manual for its using, especially
Chapter No. 7.
– Boiler servicing by an user, Chapter No. 8 – Maintenance, and Chapter No. 9 – Important warning. Please observe the below
mentioned information, in order to ensure a long-term trouble-free operation to your and our satisfaction.
HERCULES E68
boiler is a cast-iron sectional gasifying boiler designed for the combustion of wood.
Combustion of other substances (for example, plastics) is not allowable.

Boiler usage and advantages
The
HERCULES E68
boiler meets the requirements for heating of one-family houses, shops, etc.
The boiler is manufactured as a warm-water boiler with forced circulation of heating water and work overpressure up to 400 kPa (4 bar). Before
dispatching, the unit is tested with the testing overpressure of 800 kPa (8 bar). The control of the
HERCULES E68
boiler is solved with help of
automatic regulation.
Advantages of the boiler:
1. Ecological operation
2. High effectiveness of the boiler
3. Low fuel consumption
4. High service life of the cast-iron heat-exchanger and all other parts thanks to the quality of the used materials.
5. Long-term proven structure.
6. Sophisticated production technology on the automatic forming lines with permanent and proven quality of the production process (ISO 9001,
ISO 14 001).
7. Simple manipulation and maintenance.
8. Possibility of hot water heating
9. Possibility of the control of one heating circuit
10. Cooperation with storage tank
