CHECKS TO BE MADE TO ENSURE A PROPER INSTALLATION:
Before proceeding with the filling of the fuel system and subsequent burner start up, it is advisable to carry out the
following checks:
- Power line must be adequate to system's adsorbed load
- Fuses must be adequate to the system's load
- Boiler's thermostats must have been properly connected
- Voltage and frequency must be within the specified limits
- Fuel type must be the one specified by the burner manufacturer
- Feed piping section must be adequate to the requested fuel flow rate
- Filters, cocks as well as fittings must have been properly installed
- Blast tube length must be the one specified by the boiler manufacturer
- Nozzle's flow rate of the burner must be adequate to boiler's output
BEFORE PROCEEDING WITH THE FILLING OF THE OIL SYSTEM, CHECK THE FOLLOWING POINTS:
- Motor's direction of rotation (with 3 phase version)
- There must be fuel in the tank
- Fuel cocks must be open
- Fuel return piping must be free from obstructions
After having checked all the above items, proceed as follows:
- Connect a fuel pressure gauge
- Set the resistors thermostat to 0°C
- Disconnect the resistors power cable from the motor's remote control switch, and insulate it temporarily
- Unplug the safety box
- Start the burner and manually operate the motor's remote control switch until the oil system is filled up. Note: the oil
system can be considered filled when pressure gauge will show a constant reading of 16÷18 bar.
When done, shut off the burner, switch off power and restore initial conditions as follows:
- Reconnect resistors power cable
- Set the resistor's thermostat to the initial value of 120 °C
- Plug in the control box

WORKING OF THE BURNER

When all the controls, as shown in previous paragraphs, have been accomplished, it will be possible to proceed with the
burner start up.
- Switch-on the burner. When reaching the preset temperature on the working thermostat, and with boiler's thermostat
closed, the control box starts the fan, the fuel pump and the ignition transformer. At the same time, the balancing
resistors are activated, to keep fuel temperature into the heater at a constant value.
- It begins, in this way, the combustion chamber prepurging, as well as the fuel circulation in the whole circuit, so as to
obtain an uniformity of temperature which allows a correct flowing of the same. The fuel pressure, during prepurging,
shall be around 16÷18 bar. If not, adjust the pressure to the specified value through the regulator "D", purposely
