IMPORTANT
Before using the space heater, carefully read all of the instructions and follow them
scrupulously.
The manufacturer cannot be held responsible for damage to persons and/or property caused
by improper use of the equipment.
This instruction manual is an integral part of the equipment and must therefore be stored
carefully and passed on with the unit in the event of a change of ownership.
GENERAL RECOMMENDATIONS
The space heaters run on diesel fuel. Direct
combustion versions send hot air and
combustion products into the room, while
indirect combustion versions are fitted with a
flue to discharge the fumes through the
chimney.
Warning
THIS HEATER IS FOR
PROFESSIONAL USE. IT HAS BEEN
CAREFULLY DESIGNED FOR
MOBILE AND TEMPORARY
PROFESSIONAL APPLICATIONS.
IT HAS NOT BEEN DESIGNED FOR
DOMESTIC USE NOR FOR
COMFORT HEATING AND SHOULD
NEVER BE USED TO HEAT CLOSED
ROOMS WITHOUT ADEQUATE
VENTILATION.
Always follow local regulations and codes
when using this heater:
• Follow the instructions in this booklet very
carefully;
• Use only in places free of flammable vapours
or high dust content;
• Keep inflammable material at a safe distance
from the heater (minimum 3 metres);
• Make sure firefighting 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;
• The indirect combustion heater is installed
near a chimney to take away the fumes (see
the paragraph “FUMES FLUE POSITIONING
DIAGRAM”) and connected to an electrical
switchboard;
• Make sure nothing is obstructing the
aspiration and expulsion of air; movement of
air may be obstructed in various ways
including placing covers or other objects on
the heater or positioning the heater too near
a wall or other large object.
• 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 the fan.
• Unplug heater when not in use.
SAFETY DEVICES
The heater is fitted with an electronic device
that controls the flame and the maximum safe
temperature by means of a photocell and an
overheat thermostat.
The electronic device controls start/stop times
and trips the safety in case of malfunction. It
has a reset button (13) that can assume
different colours (Function Light) depending on
the function mode:
• off: heater is in idle mode or in “stand-by”
mode, waiting for heating request;
• Steady green: heater functioning normally;
• Steady red: heater in safety stop;
• Flashing orange: heating interrupted due to
excessive variations in voltage supply
(T<175V or T>265V); heating will resume
automatically when voltage returns in range
from 190 V and 250 V.
Warning
To restart heating after a safety stop,
push reset button (13) for 3 seconds.

DP65 / DP105
8

Warning
NEVER do more than two restarts in
a row: uncombusted diesel fuel may
accumulate in the combustion
chamber and suddenly flare up at the
next restart.
If the safety stop persists, it is important to find
and eliminate the cause of the stop before
restarting the heater. Push button (13) for at
least 5 seconds to launch a self-diagnosis
programme, after which the button will assume
different colours (Self-diagnosis light)
depending on the type of safety that tripped:
• Flashing orange: false flame detected during
restart cycle.
• Flashing red: no flame during restart cycle.
• Flashing red/green: no flame during work
cycle.
• Steady orange: internal error of electronic
device.
Warning
See “TROUBLESHOOTING” to
identify the cause of the malfunction.
OPERATION
Before switching on the heater and, therefore,
before plugging it into the electrical power
supply, check that the power supply
specifications are the same as those stated on
the identification plate.
Warning
• The power line must be earthed
and fitted with a residual current
circuit breaker.
• The heater plug must be inserted
into a socket equipped with a
mains switch.
The heater must be placed on a flat, stable,
and levelled surface in order to prevent it from
overturning and/or diesel leaks from the tank
filler cap.
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
heater.
Connection to the heater is made by removing
the socket cover (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);
Warning
At the end of the start cycle, the
electronic control device causes
button (13) to flash briefly to confirm
completion of the heater start cycle.
When unit is started for the first time or is
started after the oil tank has been totally
emptied, the diesel flow 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 depressing the reset button (13).
If the heater does not function, the first things
to do are:
1. Check that the tank still contains some
diesel;
2. Push reset button (13);
3. If the heater still does not function, see
TROUBLESHOOTING” to identify the
cause of the malfunction.
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 approximately 90 sec. cooling the
combustion chamber.

TRANSPORT
Warning
Before moving the heater:
• Stop the heater as indicated in the
“STOP” paragraph;
• Cut electrical power by removing
the plug from the electrical socket;
• Wait until the heater cools.
Before moving the heater, make sure the fuel
tank cap is securely attached.
Warning
Diesel may leak during handling and
transport: the fuel tank cap is not
sealed. This allows air to enter and
allows the tank to be emptied while
the heater is running.
MAINTENANCE
Warning
Before starting any maintenance
procedure, ALWAYS:
• Stop the heater as indicated in the
“STOP” paragraph;
• Disconnect electrical power by
removing the plug from the
electrical socket;
• Wait until the heater cools.
Periodic maintenance of the heater is
necessary to ensure proper performance and
to prevent failures. To ensure correct heater
function, the combustion chamber, burner, and
fan must be cleaned at regular intervals by a
qualified service technician. Maintenance
should be performed at the following periodic
intervals:
Daily maintenance (customer to perform)
 Inspect air inlet / air outlet and exhaust
stack, remove debris if any
 If any air duct is installed, secure it is fixed.
Minimize bends and keeps ducts straight.
 Verify fuel tank is full
 Verify that exhaust stack is properly installed
Weekly maintenance (customer to perform)
 Disassemble, inspect and clean fuel filter
with clean fuel
Every 50 hours maintenance (qualified
Spitwater service technician to carry out)
 Remove top cover and clean the motor, fan
blade and the interior shell
 Inspect the fuel hose assembly and check
for any leaks
Every six months maintenance (qualified
Spitwater service technician to carry out)
 Disassemble burner head
o Inspect and clean burner diffuser
o Inspect and replace nozzle if
necessary
o Clean ignition electrodes and adjust
settings
o Check air combustion setting
 Check overheat thermostat
 Inspect and clean the combustion chamber
 Open electric board, inspect electrical
components and check connections
 Check fuel pressure setting of fuel pump
Inspect and test the burner
