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
burner 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 filter in the oil suction line and in the pump.
Clean the flame detector, (fig. 12, page 5).
Check for correct fuel consumption.
Replace the nozzle (fig. 14, page 7) and check the correct position of electrodes (fig. 15, page 7).
Clean the combustion head in the fuel exit area, on the diffuser disc.
Leave the burner working without interruptions for 10 min. and check the right settings at 1 st and 2 nd
stage of all components stated in this manual. Then carry out a combustion check verifying:
Smoke temperature at the chimney;
Smoke value according to opacity smokes index according to Bacharach scale.
