IMPORTANT WARNINGS 

 

1. 

The boiler may only operate persons familiarized with this instruction manual. It is not allowed to leave children beyond control 
of adults near the boiler. Interventions into the boiler structure which could threaten the health of the servicing person or his/her 
inmates are not allowed. 

2. 

The  boiler  is  not  determined  for  using  by  persons  (including  children),  whose  physical,  sensible  or  intellectual  inability  or 
absence of experience and knowledge prevents from safety using of the consumer, until they are under supervision or until they 
are instructed of using of the consumer by a person responsible for their safety. 

3. 

You should watch the children to ensure that 

they don’t play with the consumer. 

4. 

A necessary condition for operation of this boiler is the chimney lining from the reason of possible creation of condensate in 
flue gases due to their low temperature, mainly at the minimum boiler power. A material of the chimney lining has to be resistant 
against chemical effects of condensate. 

5. 

In  case  there  is  a  danger  of  creation  and  intrusion  of  flammable  steams  or  gas  into  the boiler  room,  or  at  work  during  which 
there is a transition danger of fire or explosion (floor coating cementing, coating with flammable paintings), the boiler has to be 
timely shut-down prior the start of such works. 

6. 

IT IS prohibited to use flammable liquids for boiler kindling. 

7. 

DURING OPERATION, IT IS prohibited to overheat the boiler. 

8. 

Don’t put any objects made of flammable material on the boiler and within a distance smaller than the safe distance from it. 

9. 

While taking out ash from the boiler, no flammable materials can be placed on the distance less than 1500 mm from the boiler. 

10. 

While  operati

ng  the  boiler  at  temperature  lower  than  50  °C  can  occur  fogging  of  the  boiler  drum,  so  called  low-temperature 

corrosion,  which  shortens  the  service  life  of  the  boiler  drum.  That's  why  we  recommend  that  you  operate  the  boiler  at 
temperature of 7

0 °C and higher. 

11. 

In case of the use of an accumulating tank, it is possible to kindle the boiler again or to add fuel to it again provided the boiler is 
burnt up to the base of the furnace and the accumulating tank is discharged or cooled.  

WARNING!!! Failure to respect brings to extremal pollution of the heat-exchanger. 

12. 

After  having  finished  the heating  season,  it is  necessary  to  thoroughly  clean  up  the boiler,  flue gas  ducting  and  chimney  pot. 
Lubricate with  graphite  grease  as  follows:  pivots  and  other movable  parts  on  the boiler. It  is  necessary  to  maintain  the boiler 
room in clean and dry conditions. 

13. 

In case that the heating system is not used daily during the winter period, it is necessary to pour out water. 

14. 

Possible signs of corrosion on the boiler drum are not a defect and do not affect boiler functionality. 

15. 

A safety valve with the maximum overpressure of 400 kPa (4 bar), the dimensions of which have to comply to the nominal power 
of the boiler, has to be installed in the system. The safety valve must be positioned directly behind the boiler. No shut-off valve 
can  be  placed  between  the  safety  valve  and  the  boiler.  In  case  of  other  questions,  please  contact  our  contractual  mounting 
companies and service organizations.  

16. 

In case of triggering the two-way  safety device, when water w

hich does not comply with requirements of ČSN 07 7401 can be 

refilled, it is necessary to prepare water in the system so that it met the requirements of this standard.  

17. 

During assembly, installation and operation of the appliance it is necessary to comply with 
 
standards applied in the relevant country of destination. 

In case of violation of these conditions, no warranty repairs can be required.
