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:

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.
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
temperatures, free of impurities from the surroundings and cor-
rectly positioned.
Fan
Check to make sure that no dust has accumulated inside the fan or
on its blades, as this condition will cause a reduction in the air flow
rate and provoke polluting combustion.
Burner
Clean the outside of the burner.
Clean and grease the cam variable profile.
Boiler
Clean the boiler as indicated in its accompanying instructions in or-
der to maintain all the original combustion characteristics intact, es-
pecially the flue gas temperature and combustion chamber
pressure.
Gas leaks
Make sure that there are no gas leaks on the pipework between the
gas meter and the burner.
Gas filter
Change the gas filter when it is dirty.
UV scanner
In order to reach the UV scanner (Fig. 38), proceed as follows:
➤
extract the UV scanner 2);
➤
clean the glass cover from any dust that may have accumu-
lated.

Maintenance
DANGER
The maintenance interventions and the calibration
of the burner must only be carried out by qualified,
authorised personnel, in accordance with the con-
tents of this manual and in compliance with the
standards and regulations of current laws.
DANGER
Disconnect the electrical supply from the burner by
means of the main system switch.
DANGER
Close the fuel interception tap.
Wait for the components in contact with heat sourc-
es to cool down completely.
The gas combustion system should be checked at
least once a year by a representative of the manu-
facturer or another specialised technician.
The operator must use the required equipment dur-
ing maintenance.
WARNING
➤
Be extremely careful while troubleshooting the
detector; line voltage is present on some of the
terminals when power is on.
➤
Open the master switch to disconnect power
before removing or installing the detector.
