Maintenance
6.1 Notes on safety for the maintenance
The periodic maintenance is essential for the good operation, safe-
ty, yield and duration of the burner.
It allows you to reduce consumption and polluting emissions and to
keep the product in a reliable state over time.
Before carrying out any maintenance, cleaning or checking opera-
tions:
6.2 Maintenance programme
6.2.1 Maintenance frequency
6.2.2 Checking and cleaning
Combustion
The optimum calibration of the burner requires an analysis of the
flue gases. Significant differences with respect to the previous
measurements indicate the points where more care should be ex-
ercised during maintenance.
Flame inspection window
Clean the flame inspection window (Fig. 35).
UV scanner
Clean the glass cover from any dust that may have accumulated.
In order to reach the UV scanner, unscrew the screw 1)(Fig. 36)
and extract the flame sensor with the relevant support 2).
Combustion head
Open the burner and make sure that all components of the com-
bustion head are in good condition, not deformed by the high tem-
peratures, free of impurities from the surroundings and correctly
positioned.

Check for excess wear or loose screws in the mechanisms con-
trolling the air damper and the gas butterfly valve.
Also make sure that the screws securing the electrical leads in the
burner connections are fully tightened.
