SAFETY CHECKS
When adjustment is over always check for:
1) proper burner shutdown by opening the thermostats and air
pressure switches.
2) “lock-out” by covering the UV photocell.
To reset press the relevant button.
MAINTENANCE
At the end of the heating season it is good practice to clean the
fuel filters, the combustion head (disk, insulators, nozzles), the
combustion air passages and the UV photocell.
Use a soft material (wood, plastic) to clean the nozzle passages.
It is recommended that the nozzles be replaced every 12 working
months.
UV PHOTOCELL
Even slight greasiness will compromise passage of the UV rays
through the UV photocell bulb, thus preventing the sensitive devi -
ce inside it receiving the quantity of radiation needed for correct
operation. If the bulb is smeared with light oil, heavy oil, etc. it must
be cleaned thoroughly. Note that even gentle contact with fingers
can leave a slight film of grease which is sufficient to compromise
proper UV photocell operation. The UV cell does not “see” daylight
or the light emitted by a common bulb.
A sensitivity check can be carried out using a flame (lighter, candle)
or the spark generated between the electrodes of a common ignition
transformer. To ensure proper operation the UV cell current must be
sufficiently stable and must not drop below the minimum required
by the control box. It may be necessary to try different positions in
order to find the best one: do this by shifting (axial or rotary shift) the
body that contains the photocell with respect to the attachment strap.
The check is effected by inserting a micro-ammeter (with suitable
scale), in series, to one of the two UV photocell connection wires;
it is, of course, necessary to observe polarity ( + and - ).
USING THE BURNER
The burner features fully automatic operation; by turning the main
switch and control panel button to ON the burner is switched on.
The burner is run by the control devices described in the chapter
“Description of Operation”.
The burner automatically goes to the “lock-out” safety position when
some part of the burner or plant is working inefficiently; it is thus
good practice to make sure, before restarting the burner by resetting
it, that there are no anomalies in the power plant. The burner may
stay in the lock-out position indefinitely.
To reset the burner press the Reset button.
Shutdowns may be caused by transitory irregularities (a little water
in the fuel, air in the piping etc.); in such cases the burner, when
reset, starts without difficulty. When, instead, there is a succession
of shutdowns (3 - 4 times) the operator should desist and, after
checking that fuel is actually reaching the burner, should contact
the local authorised servicing centre to have the problem resolved.
