■
Restore the working by moving backward the control box, keeping
it supplied and acting on the reset tongue (see fig. 17).
■
Check the efficiency of:

MAINTENANCE
The burner requires periodic maintenance carried out by a qualified and authorised technician in conformity
with legislation and local standards.
Maintenance is essential for the reliability of the burner, avoiding the excessive consumption of fuel and
consequent pollution.
Before carrying out any cleaning or control always first switch off the electrical supply to the burn-
er acting on the main switch of the system.
THE BASIC CHECKS ARE:
■
Check that there are not obstructions or dents in the supply or return oil pipes.
■
Clean the flame detector
(7, fig. 1, page 1).
■
Clean the filter in the oil suction line and in the pump.
■
Check for correct fuel consumption.
■
Replace the nozzle, (see fig. 11, page 6) and check the correct position of electrodes (fig. 15, page 8).
■
Clean the combustion head in the fuel exit area, on the turbolating disc.
■
Leave the burner working without interruptions for 10 min. and set rightly all the components stated in
this manual. Then carry out a combustion check verifying:
●
Smoke temperature at the chimney;
●
Content of CO
2
( % );
●
Content of CO (ppm);
●
Smoke value according to opacity smokes index according to Bacharach scale.
