GENERAL RECOMMENDATIONS

The generator described in this manual is a portable oil-fuelled in-
frared heat generator.
Its easy handling and large fuel tank allow it to be used locally and
temporarily with complete stand-alone operation. The area to be heated
is therefore hit by an even and uniform flow of heat, as can be seen by
the shape of the irradiation cone (22), without air movement.
The unit is a direct combustion hot generator that works by send-
ing both hot air and combustion products in the room you wish to heat:
all the necessary precautions must therefore be taken to guarantee a
sufficient exchange of air.
Always follow local ordinances and codes when using this heater:
• Read and follow this owner's manual before using the heater;
• Use only in places free of flammable vapours or high dust con-
tent;
• Never use heater in immediate proximity of flammable materials
(the minimum distance must be 3 m);
• Make sure fire fighting equipment is readily available;
• Ensure that the machine resting surface or ground is not made of
flammable material;
• Make sure sufficient fresh outside air is provided according to
the heater requirements. Direct combustion heaters should only
be used in well vented areas in order to avoid carbon monoxide
poisoning;
• Never block air inlet (rear) or air outlet (front);
• In case of very low temperatures add kerosene to the heating oil;
• Make sure heater is always under surveillance and keep children
and animals away from it;
• Before starting the heater always check free rotation of ventilator;
• Unplug heater when not in use.
SAFETY DEVICES
The unit is fitted with an electronic flame control box. In case of
malfunction this box will cut in and stop the heater, at the same time
the pilot lamp in the control box reset button (13) will light up.
Warning
The re-engagement push-button emits a different colour
light, depending on the state of the machine:
• green, when the machine is running regularly;
• red, when the machine in safety stop: to restart, the
re-engagement button must be pressed (13)
• yellow, when it is in "stand-by": to restart, it is not
necessary to press the re-engagement push-button
(13), as operation will resume automatically.
Heaters are also equipped with an overheat thermostat safety cut
out which will stop the heater in case of overheating. This thermostat
will reset automatically but you will have to depress button (13) on
control box before being able to restart the heater.
OPERATION
Before any attempt of starting the heater is made, check that your
electrical supply conforms to the data on the model plate.
Warning
Mains must be fitted with a thermo-magnetic differren-
tial switch.
Unit plug must be linked to a socket with a mains
switch.
The hot generator must be placed on a flat, stable and level surface
to avoid machine tipping and/or gas oil leakage from the tank fuel cap.
The flow of heat can be directed upward with an approximately 10° an-
gle: loosen the two locking knobs (A) and tilt the combustion unit by
pressing on the handle until the desired angle is reached, then lock the
knobs (A) by screwing them.
IMPORTANT
damages to goods or persons due to improper use of units.
Warning
Before start-up, always ensure the guard (B) has been
completely pulled out, so as to guarantee maximum pro-
tection of the machine resting surface.
B
You can run the generator in manual by setting switch (14) to ON.
The generator can only work automatically when a control device,
such as for example a thermostat or a timer, is connected to the gener-
ator. Connection to the generator is made by removing the socket cov-
er (15) and inserting the thermostat plug.
To start the machine you must:
• if connected to the thermostat, turn the switch to (ON +
• if not connected to the thermostat, turn the switch to (ON);
For the -2 or -2 SPEED models it is possible to select the thermal
power level, by turning the switch (18) to the first stage position (I S)
or to the second stage (II S): the corresponding levels of heat are con-
tained in technical Table I.
When unit is started for the first time or is started after the oil tank
has been totally emptied, the flow of oil to the burner may be impaired
by air in the circuit. In this case the control box will cut out the heater
and it might be necessary to renew the starting procedure once by de-
pressing the reset button (13).
Should the heater not start, check that oil tank is full and depress
reset button (13).
Should the heater still not work, please refer to chapter "OB-
SERVED FAULTS, CAUSES AND REMEDIES".
Warning
Never stop the machine by unplugging the electrical
plug: this could cause overheating.
STOPPING THE HEATER
Set main switch (14) on "0" position or turn thermostat or other
control device on lowest setting.
The flame goes out and the fan continues to work for approx. 90
sec. cooling the combustion chamber.
TRANSPORT
Warning
Before making any attempt to restart heater find and
eliminate reason of overheating.
