To ensure that the heater continues to work

properly, it is necessary to periodically clean the

combustion chamber, the burner and the fan.

disconnect the plug from the

power supply and wait for the

heater to cool.

Every 50 hours of use it is necessary to:
• Dismantle the ﬁlter cartridge, remove it and

clean it with clean fuel oil.

• Remove the exterior cylindrical casing and

clean the inside and the blades of the fan.

• Check the condition of the cables and the high

voltage connections on the electrodes.

• Dismantle the burner, clean the parts, then clean

the electrodes and adjust them, if necessary, to

the distance indicated in Electrode Spacing on

page 7.
