Maintenance - Riello G3MC Installation, Use And Maintenance Instructions

MAINTENANCE

The burner requires periodic maintenance carried out by a qualified and authorised technician in con-
formity with legislation and local standards.
Periodic maintenance is essential for the reliability of the burner, avoiding the excessive consump-
tion 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 there are no occlusions or obstructions in the inlet or return pipes, in the air suction areas and
®
in the combustion product waste pipe.
Clean the filter in the oil suction line and in the pump.
®
Check for correct fuel consumption.
®
Check that the burner electrical connections are correct.
®
Replace the nozzle and check the correct position of electrodes.
®
Clean the combustion head in the fuel exit area.
®
Check that the positioning of the combustion head is correct and that it is properly fixed to the
®
boiler.
Check that the air damper is positioned correctly.
®
Let the burner run at full capacity for about ten minutes, setting all the elements correctly as explained in
this manual. Then carry out the analysis of the combustion by checking:
- Smoke index as per the Bacharach scale;
- NOx content (ppm);
20013749
- CO percentage (%);
2
- Smoke temperature at the chimney.
8 GB
- CO content (ppm);
