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

OPERATION OF BURNER WITH HEAVY OIL

When all the controls, as shown in previous paragraphs, have been accomplished, it will be possible to pro-

ceed 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 cir-

cuit, so as to obtain an uniformity of temperature which allows a correct flowing of the same. The fuel pres-

sure, 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).

- At the end of the prepurging, the control box shut off the solenoid valve “O” while opening

the 1st stage valve (for example valve “A”), allowing the burner ignition in Low Flame.

Afterwards, it will be opened the 2nd stage valve “B” which, while allowing the fuel flowing

through both nozzles, permit the burner’s High Flame ignition, i.e. at the full power.

- In order to have a correct combustion, adjust the combustion air flow for both Low and High flame.

During flow rate adjustement, it is possible to manually switch from Low Flame to High Flame and viceversa,

through the LOW/HIGH manual switch. When all adjustments are made, leave the switch in II (HIGH)

position.

- The fuel pressure during burner’s working shall be set to 23 bars.
