Dear customer,
thank you for buying the general – purpose VIADRUS U 22 boiler and thus showing belief in the company VIADRUS a.s.
At first read this operating manual (especially Chapter Nr. 7 – User’s boiler service and Chapter Nr. 9 – Important notice) to get used to a proper
usage with your new product from the very beginning. We request to maintain the further mentioned information and particularly to perform the
prescribed annual checks by an authorized specialized company by which a long – time failure – free operation of your boiler - to your and our
satisfaction - is secured.
The boiler VIADRUS U 22 is a general – purpose cast iron sectional low – pressure boiler intended for burning of:
- solid fuels coke, anthracite, wood commercial marking VIADRUS U 22 C
wood (optionally coke and anthracite) commercial marking VIADRUS U 22 D
- gas fuels natural gas commercial marking VIADRUS U 22 P
- liquid fuels boiler oil extra light – TOEL commercial marking VIADRUS U 22 N
Burning of other materials such as plastic is unallowable.
The boiler VIADRUS U 22 is not intended for the Czech market.
1 Usage and advantages of the boiler
Two and three – sectional size of the boiler VIADRUS U 22 is appropriate for heat source reconstruction in self – contained flats, for smaller
residential and recreational facilities. Bigger sizes of the boiler meet the requirements of heating the family houses, shops, schools, etc.
The boiler is produced as hot – water with natural and forced circulation of heat water and operational overpressure to 800 kPa (8 bar).
The VIADRUS U 22 D boiler is different from the VIADRUS U 22 C boiler version by its enlargement of the stoke hole so that it is possible to
burn even bigger clogs up to the average of 220 mm. By burning wooden logs the heat work difficulty is considerably reduced and the service
quality is increased. The amount of ash is also substantially smaller and it is possible to further use it as fertilizer.
Advantages of the boiler:
1. High operating life of cast iron exchanger and all other parts with respect to the quality of used materials.
2. Design approved in the long term.
3. Elaborate production technology on automatic forming lines with consistent and approved quality of the production process (ISO 9001,
ISO 14 001).
4. Efficiency of coke and anthracite burning – 75 – 80 %, efficiency of wood burning – 75 %.
5. Simple service and maintenance.
6. Low demandingness for chimney draught
7. Power gradation according to the sections
8. Possibility of boiler transformation of burning of solid fuels to gas or liquid fuels or vice versa.
