THEORY OF OPERATION
The ventilation needed for proper combustion is produced by a
fan inside the burner. The air exits the burner sleeve and mixes
with the fuel which is nebulised by a high-pressure nozzle. The
fuel is aspirated from the fuel tank by a rotary pump which forces
it at high pressure up to the nozzle for nebulisation.
OPERATING INSTRUCTIONS
WARNING: Before putting the generator in function, and
therefore before connecting it to the electrical system,
you must check to see if the electrical systems technical
characteristics correspond to those on the identifi cation
plate of the generator.
STARTING THE GENERATOR
1. Follow all of the safety information.
2. Fill the tank with diesel fuel or kerosene.
3. Close the fuel cap
4. Plug the alimentation cord into a grounded wall plug with
the same tension as the one written on the generator's
identifi cation plate.
STARTING WITHOUT A THERMOSTAT
• BURNER XL9 E
Set the switch (B Fig. 5) to the ON position (I). It begins the
period of pre-ventilation and after approximately 10 seconds
ones the combustion has beginning.
• BURNER XL9 S
WARNING: Before starting the generator to make sure
that the button (C Fig. 5) is in position
Set the switch (B Fig. 5) to the ON position (I).It begins the pe-
riod of pre-ventilation and after approximately 10 second ones
the combustion has beginning.
For having the maximum potentiality portare set the switch (C2
Fig.5) to the position.
STARTING WITH A THERMOSTAT
Regulate the thermostat or the control device (for example a tim-
er), if connected, so that it will allow the generator to function.
WARNING: The generator
automatically when the control device, for example a
Thermostat or a Timer, is connected to the generator. To
connect the control device to the machine consult the
paragraph entitled "ELECTRIC DIAGRAM".
Before starting the machine or after the fuel line has been
completely emptied, the fuel fl ow to the nozzle should be
insuffi cient to cause the intervention of the security device which
controls the fl ame (see the "SAFETY DEVICE" paragraph)
that stops the generator. In this case, after having waited
approximately one minute, push the Reset button (D Fig. 5 and
6) and start the machine.
If the machine isn't working you should fi rst control the
following:
1. Make sure that the fuel tank (N Fig. 4) still contains fuel;
2. Press the Restart button (D Fig. 5 and 6).
If the generator still isn't functioning consult the "FAULTS AND
THEIR LIKELY CAUSES" paragraph to identify the cause.
WARNING: Before the second ignition (generatore extin-
guished and adequately cold) to assure the blocking of
the screws that block the anterior defl ector (L Fig. 4).
.
can ONLY function
WARNING: The electric power that feeds the generator
must be grounded and have a differential magnetic-
thermal switch. The generator's electric cord must be
attached to a plug equipped with a section switch.
TURNING THE GENERATOR OFF
Turn the switch (B Fig. 5) to the OFF position (O) or turn the ther-
mostat or control device (Timer) off if there is one connected.
The fl ame will go out and the ventilation will continue until it has
fi nished its post-ventilation cycle (cooling down).
WARNING: Before unplugging the alimentation cord from
the wall, wait until the post-ventilation cycle is completely
fi nished (it will take approximately 3 minutes to cool
down).
SAFETY DEVICE
The generator is equipped with a safety device (L Fig. 6), which
controls the fl ame. If one or more anomalies occur when the
generator is functioning, the device will block the burner and the
RESET button (D Fig. 5 or 6) will light up.
The generator also has a post-ventilation device which enables
optimal, automatic cooling of the combustion chamber for some
3 minutes.
Before turning the generator on again you must identify and
eliminate the cause that blocked the machine.
MOVING AND
TRANSPORTATION
"NOTICE: before raising or moving the machine ensure
that the fuel tank caps (F and H Fig.3 ) are fi rmly closed".
TRANSPORT
The generator is easy to move and it may be fi xed in a raised
position thanks to its special eye-bolt mechanism (B Fig. 3 or
Fig. 7). This enables it to be set in the most suitable position for
heating, defrosting and drying.
Figur 7 - Hooks in order to raise.
MOVEMENT
Before picking up or moving the machine you must check to in-
sure that the tank caps (G Fig. 3) are tightly shut. The generator
may be supplied with a rotating wheel. In this case, if the fl oor-
ing allows it you may push the generator like a cart. In the case
the machine does not have rotating wheels it is necessary to
