Checking the parts and components
Pump
The pressure must be stable at the value set during installation, and in any case between 10 and 14 bars.
No noise must be produced.
In the case of instable pressure or noisy pump, disconnect the exible pipe from the line lter and feed in
the fuel from a tank located near the burner. This identi es whether the cause of the anomaly is the inlet
pipe or the pump.
Filters
Check and clean or replace, if necessary, the lters in the line, pump and nozzle.
If there is rust or other impurities in the pump lter, use a separate pump to remove water and other impu-
rities from the bottom of the tank.
Fan
Check that dust is not accumulated inside the fan and on the rotor blades: this reduces the air ow and
causes, as a consequence, polluting combustion.
Combustion head
Check that all the parts of the combustion head are intact, not deformed by the high temperatures, free of
impurities from the surrounding environment, and correctly positioned.
Nozzles
Avoid cleaning the hole of the nozzles, so as to not damage them
Replace the nozzles every 2-3 years, or when necessary. Combustion must be checked when changing
the nozzle.
Photo cell
Clean the glass for dust. The photo cell is pushed into place; to remove it, simply pull it out.
Flexible pipes
Check that they are in good condition, that they have not been stepped on or deformed.
Tank
Every 5 years or so, remove the water from the bottom of the tank using a separate pump.
