IMPORTANT

Before using the heater, read and understand all
instructions and follow them carefully. The manufacturer
is not responsible for damages to goods or persons due
to improper use of units.

GENERAL RECOMMENDATIONS

The heater described in this manual is a portable oil-fuelled

infrared heat generator running on heating oil.

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 (18), without air movement.

The unit is a direct combustion hot generator that works by
sending 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;

• THE INSTALLATION OF THE UNIT SHALL BE IN
ACCORDANCE WITH THE REGULATIONS OF THE
AUTHORITIES HAVING JURISDICTION. Also, as a
recommended installation practice reference should be made to
the current issue of CSA B139, Installation Code for Oil Burning
Equipment in Canada and NFPA 31 Standard for the Installation
of Oil-Burning Equipment In the USA;

• Use only in places free of flammable vapours or high dust
content;

• Never use heater in immediate proximity of flammable materials
(the minimum distance must be 10 feet);

• Make sure fire fighting equipment is readily available;

• 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;

• A rough estimate of opening required for each gallon (US) of
capacity is three square foot at heater level, for direct-fired
heaters;

• The heater is installed and connected to an electrical
switchboard;

• Ensure that the machine resting surface or ground is not made
of flammable material;

• Minimum clearances from combustible material must be:
30” from side and rear (air inlet) of heater
80” from ceiling
40” on air outlet of heater.

• Never block air inlet (rear) or air outlet (front);

• In case of very low temperatures add kerosene to the heating
oil;

• Connect the power cord to the mains and wait 15 min at least
be fore starting heater, to allow pre-heated filter warming
heating oil inside the filter;

• 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;

• Heater is not ductable.

• 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 reset push-button emits a different light,
depending on the state of the machine:

• off, when the machine is running regularly;

• red, when the machine is in safety lock-out mode: to
restart it , the reset button (13) must be pressed.

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

differential 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 5°
angle: loosen the two locking knobs (A) and tilt the combustion unit
by pressing on the handle (18) until the desired angle is reached,
then lock the knobs (A) by screwing them.

Warning

Before start-up, always ensure the guard (B) has been
completely pulled out, so as to guarantee maximum
protection of the machine resting surface.

You can run the generator in manual by setting switch (14) to ON.

The heater can only work automatically when a control device,
such as for example a thermostat or a timer, is connected to the
generator.

Connection to the heater is made by removing the socket cover (4)
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).

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 or twice by depressing the reset button (13).

Should the heater not start, check that oil tank is full and depress
reset button (1).

Should the heater still not work, please refer to chapter
“OBSERVED FAULTS, CAUSES AND REMEDIES”.

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

Before heater is moved, it must be stopped and unplugged. Before
moving the heater wait till it has totally cooled off and make sure oil
tank cap is securely fixed.

such as for example a thermostat is connected to the generator.

Mains must be fitted with a breaker switch.
