12 Commissioning
The entire installation shall comply with the regulations that are applicable for this equipment. The boiler shall be compatible with the local
connecting conditions (checking the parameters of the boiler with the information on the name plate). The boiler can only be commissioned
by organizations that are authorized and trained for this purpose by the manufacturer. The minimum pressure in the heating system is
0,8 bar. It is necessary to open all closing valves and make sure that no gas is leaking. Connect the boiler to the electric power mains. Check
the gas distribution line after the gas valve. Check the safety valve function. Then check the pump operation. During the operation of the boiler it
is necessary to check removal of the condensate from the boiler and also from the chimney lining, if applicable.
During the first start of operation of the boiler it is necessary to train the user in accordance with this manual and to hand over this
manual to the user.
Then it is necessary to perform:
- inspection revision before commissioning,
- inspection for any water leakages,
- inspection of instrumentation and safety controls.
