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 device 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 attach-
ment 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.
