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 oper-
ations:

Checking and cleaning
Combustion
The optimum calibration of the burner requires an analysis of the
flue gases.
Significant differences with respect to the previous measure-
ments indicate the points where most care should be exercised
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 that
the relative materials are not corroded and that they are correctly
positioned.
Check the gas outlet holes for the ignition phase (in the distributor
of the combustion head) are free of impurities or rust. If in doubt,
disassemble the elbow.
Flame inspection window
Periodically clean the glass of the flame inspection window
(Fig. 34).
Gas distributor
Periodically check that the combustion head is clean. A tool has
to be used, as shown in Fig. 35, to make sure that the holes for
the gas to pass through are free and without any impurities.

tents of this manual and in compliance with the
standards and regulations of current laws.
DANGER
Turn off the burner's power supply using the main
system switch.
DANGER
Turn off the fuel interception tap.
Wait for the components in contact with heat
sources to cool down completely.
The gas combustion system should be checked at
