Dear customer,
thank you for buying the general – purpose VIADRUS HERCULES U 22 furnace and thus showing
belief in the company ŽDB GROUP, a.s., VIADRUS division.
At first read this operating manual (especially Chapter Nr.7 – User’s furnace service and Chapter Nr.
8 – 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 furnace - to your and our satisfaction - is secured.
The furnace VIADRUS U 22 is a general – purpose cast iron sectional low – pressure furnace 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
Burning of other materials such as plastic is unallowable.
1. Usage and advantages of the furnace
Two and three – sectional size of the furnace VIADRUS U 22 is appropriate for heat source
reconstruction in self – contained flats, for smaller residential and recreational facilities. Bigger sizes of the
furnace meet the requirements of heating the family houses, shops, schools, etc.
The furnace is produced as hot – water with natural and forced circulation of heat water and operational
overpressure to 800 kPa.
The VIADRUS U 22 D furnace is different from the VIADRUS U 22 C furnace 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 furnace:
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 furnace transformation of burning of solid fuels to gas or liquid fuels or vice versa.
