Notes on safety for the maintenance
The periodic maintenance is essential for the good operation,
safety, 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 op-
erations:
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.
Gas leaks
Make sure that there are no gas leaks on the pipework between the
gas meter and the burner.
Flame inspection window
Clean the flame inspection window (Fig. 32).
UV scanner
Clean the glass cover from any dust that may have accumulated.
In order to reach the UV scanner, extract the flame sensor
1)(Fig. 33).
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.
Burner
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.
Combustion
Adjust the burner if the combustion values found at the beginning
of the operation do not comply with the regulations in force, or do
not correspond to good combustion.
