COMMISSIONING
General Controls
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.
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.
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.
Commissioning order
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.
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 (modulating 25 bar).
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.
