COMMISSIONING
Before Commissioning
Electrical Connection
Perform electrical connections according to the diagram provided with the burner. Follow general
security rules during installation of electric wiring and making connections. Connect the earthing terminal
in electric panel to the earthing installation.
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 boiler safety thermostats and, if it is a two-stage burner, then make sure that there are
two thermostats.
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?
Ø
Is there sufficient air in boiler room (ventilation section cm² = boiler capacity kW x 7)
Ø
Has the air of the gas line been removed? Has a sealing test been made?
Commissioning order
Operating with Light Oil ;
Ø
After performing the above mentioned controls, open the fuel tank valve.
Ø
Open the valve upstream of the fuel filter.
Ø
Check direction of motor rotation.
Ø
Open the pump’s vent plug and place the manometer (0-40 bar).
Ø
Turn on the burner switch (turn to position 1).
Ø
When the burner starts up, the motor is activated and turns the pump at the same time.
Ø
It actuates pre-purge and discharges the residual gases remaining in the boiler from the funnel.
Ø
After the pre-purge, fuel is delivered from the nozzle. The fuel meets the flame from the ignition
electrodes and the combustion starts.
Ø
After combustion of the burner, the pump pressure is adjusted (light oil: two stage; 14 bar,
modulating; 25 bar).
Ø
If the burner has two stages, the switch is brought to position “2”, and the capacity of the burner is
increased through servomotor. Ideal combustion is obtained by increasing the amount of air by the
fuel given according to analyses value.
Ø
The boiler thermostat is adjusted as desired (70-90°C for central heating boilers).
Ø
For the safety of the system, check the boiler thermostats and observe the deactivation of the
burner.
