OPERATION OF BURNER WITH LIGHT-OIL FUEL MULTICALOR

Once having installed the burner, check the following items:

- The burner power feeding and the main line protection fuses

- The correct length of pipes and that the same are sealed.

- The type of fuel, which must be suitable for burner.

- The connection of boiler's thermostats and all the safeties.

- The motor rotation direction.

- The correct calibration of the motor's thermal protection.

When all the above mentioned conditions are checked and accomplished, it is possible to go on with burner's tests.

Power the burner. The control box feeds the ignition transformer and the burner's motor at the same time, which will

run a prepurging of the combustion chamber for about 20 sec.

At the end of prepurging, the control box opens solenoid valves and the burner starts. After a safety interval of 5

seconds and a correct ignition, the control box turns off the ignition transformer and, 10 seconds later, sets the motori-

sed air damper to its maximum opening (High flame). In case of faulty ignition, the control box switches the burner

into safety condition within 2 second. In such a case, the manual rearming of the burner shall not take place before 30

seconds have elapsed from the burner's safety shutdown. In order to obtain an optimal combustion, it is necessary adju-

st the LOW - HIGH flame air flow, according to the instruction given further on. During such a phase, it will be possi-

ble to manually switch between HIGH and LOW flame and viceversa, through the High/Low flame switch. At the end

of the adjusting phase, leave the switch in position AUTO.

PRESSURE REGULATING VALVE ADJUSTMENT

1) Remove the cap A of the pressure

regulating valve TV.

2) Loosen the fixing nut B and use an

allen wrench on the screw C to adjust

the delivery oil pressure. To increase the

pressure turn clockwise, to decrease the

pressure turn anticlockwise.

3) Tighten the nut B and pay attention

not to turn also the adjusting screw.

4) Screw on the cap A, back to its pre-

vious position.
