2. The boiler environment: there must be ensured a constant air supply and ventilation in terms of
Č
SN 07 0703.
3. In order to prevent the boiler from sweating followed by low-temperature corrosion at the places
where there is expected a more permanent operation at lower temperatures (transition periods, at
the heating system with a large volume of heating water, low-temperature regime etc.) it is
necessary to guarantee that the return water temperature doesn’t drop below 50 °C. The best way
is creation of boiler ´s own circuit.
4. Only the adult persons can operate the boiler.
5. The boiler is not destined for the use by persons (incl. children) whose physical, sensual or
mental disability or lack of experience and knowledge prevent them from a safe use of the
appliance unless they are supervised or if they were not instructed on the use of appliance by a

7. The boiler connection follows
Č
SN 33 2000–4–41 (including the protective equipotential bonding)
8. The boiler is connected to a fixed distribution electricity network 230 V/50 Hz with corresponding
protection and a preliminary switch disconnecting al network poles.
9. In case of a long-term boiler shutdown it must be disconnected from the electricity network
10. In case of a long-term boiler shutdown and a danger that the heating system gets frozen through
it is necessary to empty the whole heating system in order to prevent it from damaging its
individual parts.
11. In case of a long breakdown in flue gas installation from the horizontal (countermove, blocked
chimney) the combustion gases reflux fuse will close the fuel supply to the boiler. The fuse
unblocking can be done by user by means of unblocking pushbutton TS. A repeated boiler start
can only be done after cooling down the combustion gases reflux fuse sensor it means after
10minutes.
12. The boiler room must be kept clean and free of dust. From the boiler room there must be
excluded all sources of pollution and during the works(insulating works, boiler room cleaning)
that cause dustiness the boiler must be put out of operation. Even a partial dirt deposits on the
burner result in burning process deterioration, endanger an economic and reliable boiler
operation.. We don’t recommend to keep any domestic animals (dogs, cats etc.) in the boiler
room.
13. In case of a danger that the combustible vapours or gases will develop or enter the boiler room
or during the works that are connected with temporarily developed fire or explosion risk (like
gluing the flooring materials, painting with combustible paints), the boiler must be put out of
operation in a good time before the works initialisation.
14. On the boiler and within a distance lower than the safe distance from it there must not be put any
articles made of combustible materials.
15. The user is obliged to charge with assembly, commissioning, regular maintenance and the faults
elimination only a professional contracting service that is accredited by VIADRUS a.s., the boiler
manufacturer, otherwise the guarantee for a proper boiler function becomes void. „The certificate
of VIADRUS G 90 boiler quality and completeness“ serves as the “Certificate of warranty“ after
having been filed in by the contracting service organization.
16. It necessary to keep maintaining the boiler regularly once a year according to the chapter as
follows.
17. During assembly, installation and operation of the appliance it is necessary to comply with
standards that apply in the relevant country of destination.
If you fail to meet these conditions you cannot requisite the guarantee repairs.
