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 installed on the heating circuit (see figure).

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 3phase 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.

- Disconnect the resistors power cable from the motor’s remote control switch, and insulate it temporarily

- Unplug the safety box

- To press manually with a screwdriver on the pump motor’s remote control switch, until the oil system is filled

up(fig.B).

Note: the oil system can be considered filled when pressure gauge will show a constant reading. When done,

restore initial conditions.
