General Controls
Make sure to perform the following controls before commissioning the burner.
Ø
Installation of the burner to the boiler is checked.
Ø
Check the fuel line (are the pipe diameters and the pipe installation correct?).
Ø
Check energy input cables and voltages.
Ø
Check the fuel nozzles according to the boiler capacity.
Ø
Prior to operating the burner, control the boiler water level.
Ø
Make sure water circulation system is turned on, and steam boiler and water feed pumps and
boiler inlet - outlets are open.
Ø
Is there electricity current?
Ø
Is there gas?
Ø
Has the boiler explosion lid been controlled?

Commissioning order
Operating with Heavy Oil;
Ø
Open the main gas valves.
Ø
Open operating switch on the burner panel.
Ø
Turn modulating control switch to automatic.
Ø
Turn the fuel selector switch to “Heavy Oil” position.
Ø
Check the temperature and pressure set values from the modulating control unit.
Ø
Burner fan motor will be activated.
Ø
Check if the gas pressure from the inlet manometer is 30 bar.
Ø
Air dampers will open during pre-purge and ignition will take place once air dampers are in start position.
Ø
3 sec. later, the F.O. operating valve will be opened and combustion will occur.
Ø
Flame control system will start to flame control.
Ø
In modulating burner, the burner goes into max. capacity according to the signal from the modulating
control unit.
Ø
When the boiler water temperature or steam pressure increase, the modulating control unit will cause
burner to run with min. capacity.
Ø
If the boiler water temperature or steam pressure increases despite the operation of burner with min.
capacity, the modulating control unit will stop the burner.
