STARTING THE HEATER

Before turning on the heater and therefore before attaching it
to the mains power supply, check that the characteristics of the
mains power supply are the same as those indicated on the
identification label.
WARNING: The electric power cable of the heater must
be earthed and must have a differential magnetothermal
switch.The electric plug must be connected to a socket
which has a disconnecting switch.
The heater can only work automatically when a control mecha-
nism, for example a thermostat or clock, is connected to it by at-
taching the cable to terminals 2 and 3 of plug 2 (Fig. 6) supplied
with the product (the electric wire that links the two terminals
must be removed and remounted only if the heater is to be used
without the control mechanism).
To turn on the machine, do the following:
• If the control mechanism is connected, adjust it so that the
machine can function (for example, the thermostat must be set
to the maximum temperature).
• Flip switch 3 (Fig. 6) to the position with the symbol: "ON" -
the fan comes on and after several seconds the heater starts
burning.
The first time the heater is used, or after the fuel circuit has been
completely drained, the flow of fuel oil to the nozzle may be in-
sufficient and may activate the flame cut out mechanism, which
will turn off the heater;if this happens, wait for about a minute
and then press the reset button 1 (Fig. 6) to start the machine
again.
The first steps to take if the machine does not work are the fol-
lowing:
1. Check that there is fuel in the tank.
2. Press the reset button 1 (Fig. 6).
3. If the heater still does not work, consult the "TROUBLESHO-
OTING" guide.

TURNING OFF THE HEATER

To turn off the machine, move switch 3 (Fig. 6) to the "0" position
or adjust the control mechanism, for example turning the ther-
mostat to a lower position. The flame will go off and the fan will
continue to function until the combustion chamber has cooled
down completely.

SAFETY DEVICES

The heater is equipped with an electronic device to control the
flame. If there is an anomaly in the functioning, the machine will
be turned off and the reset button light 1 (Fig. 6) will come on.
An over-heating thermostat cuts in and shuts off the fuel supply
if the heater overheats:the thermostat resets itself automatically
when the temperature in the combustion chamber diminishes
and reaches the maximum permitted value.
Before turning the heater on again, the cause of the overheating
must be identified and removed (for example, a blockage in the
suction orifice and/or of the air flow duct, the non-functioning of
the fan). To turn on the machine again, press the reset button 1
(Fig. 6) and repeat the specific instructions outlined in the sec-
tion "STARTING THE HEATER".

PREVENTATIVE
MAINTENANCE PROGRAMME
To ensure that the heater continues to work properly, it is neces-
sary to periodically clean the combustion chamber, the burner
and the fan.
WARNING: The following steps must be carried out befo-
re servicing the heater: turn the heater off, following the
instructions in the previous section; 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 connec-
tions on the electrodes.
• Dismantle the burner, clean the parts, then clean the electro-
des and regulate them to the distance indicated on in the elec-
trode regulation diagram (Fig. 9-10).
