Boiler advantages:
1. A high operating liability and long service life thanks to high quality grey cast iron with lamellar graphite.
2. Top quality construction of cast-iron sections with reduced weight compared to previous versions, which
reduces the condensation occurrence thus the danger of low-temperature corrosion.
3. Economical low-temperature operation without condensation occurrence.
4. High boiler efficiency up to 93 %.
5. Regulation and safety elements reliability.
6. Equipped with combustion products return flow fuse which in case of an insufficient chimney draught
shuts down the boiler thus increasing the boiler safety.
7. Possibility to connect some of offered superior regulations according to the customer´s demand on the
heating comfort level.
8. Two-stage boiler working regime by means of HIGH-LOW coil.
9. Low contents of pollutants in combustion products (VIADRUS GARDE G 42 ECO) is deeply below the
values set by MŽP 05-97 „ Environmentally friendly product“ Direction „ and it meets the requirements
set by the most strict European standards like the “Blue angel “ limits.
10. A high combustion space enables a clean flame burnout.
11. When using the pump thermostat there is watched the minimum boiler water temperature.
12. The boiler enables to connection to stack hot service water heater and guarantees its preferential
heating.
13. Simple operation and maintenance. The boiler drum can be easily cleaned mechanically by using the
enclosed brush.
14. The boiler can also be installed in the spaces where connection to chimney is impossible if there is
mounted the combustion products ventilator that enables the combustion products drawing-off into
outdoor air directly through the enclosure wall.
