CLEANING THE ELECTRO-MAGNETIC VALVES
Remove the nut (fig. 21) to slide the coil off and unscrew the 4 fixing screws of the piece of pipe. Clean all components,
making sure the orifices for fuel flow are perfectly free from obstructions. Reassemble all parts, making sure the gaskets
are clean.

CLEANING THE TANK FILTER
- Periodically clean the tank filter (fig. 12) using diesel or gasoline. Be careful not to tear the filtering net. If the filter is very
dirty the pressure at the nozzle will drop, although the manometer on the pump will detect normal pressure.
REGULAR BURNER OPERATION
The burner has automatic operation: when supplied by means of the main switch it will remain subjected to command and
control organs (TA, TC etc), and when the water in the boiler reaches 70° C (if this is the calibration value of the boiler
thermostat) the burner will stop. When the temperature drops to 65-60° C, the burner will start again. And so on until the
temperature reaches 20° C (if this is the calibration value of the room thermostat) in the area where the room thermostat is
placed. At this point the burner will remain still until the temperature in the area where the room thermostat is placed drops
about 1-2° C. When this happens the burner starts again and will alternate between on and off to keep room temperature
constant.
