USE OF THE BURNER
The burner operates fully automatically: it is activated
by switching on the main switch and the control panel
switch.
Burner operations are controlled by command and
control devices, as described in chapter "Operation
description".
The "block" position is a safety position automatically
taken up by the burner when a particular part of the
burner or of the system is inefficient. Therefore, it
is good practice, before unblocking the burner and
starting it up again, to check that there are no defects
in the heating plant. The burner may stay in the lock
position without any time limits.
To unlock press the appropriate push-button (reset).
Blocks can be caused by transitory flows (a little water
in the fuel, air in the pipes, etc.); in these cases, if
unblocked, the burner will start up normally. When,
however, blocks occur repeatedly (3 or 4 times), do
not keep on trying to unblock the burner, first check
that there is fuel in the tank and then call the Technical
Assistance Service to repair the defect.
MAINTENANCE
It is recommended to carry out the following operations
at the end of the heating season.
• For burners which use diesel oil:
remove the filters, nozzle, turbulator disc and
the ignition electrodes and clean thoroughly with
solvents (petrol, trilene, oil). Use wood or plastic
to clean the nozzle; avoid the use of metal tools.
• Clean the photocell.
• Have the burner cleaned and, if necessary, also
the chimney by specialized personnel (stove
repairer); a clean burner is more efficient, lasts
longer and is quieter.
• For gas burners,
periodically check that the gas filter is clean.
• In order to clean the combustion head, its
components must be disassembled. Be careful
during the reassembly operations to exactly centre
the gas diffuser with regard to the electrodes,
making sure that they are not earthed, which
would result in the locking of the burner. It should
also be checked that the ignition electrode spark
occurs only between the electrode itself and the
perforated sheet disk.
ADJUSTING THE MODULATION
CONTROL SERVOMOTOR
Use the corresponding red rings (A - Z - M - V ) to modify the adjustment of the 4 utilized
cams. Pushing with sufficient force in the desired direction, each (red) ring can turn
with respect to the reference scale. The pointer on each red ring indicates the rotation
angle set for each cam on the respective reference scale.
