SELF-STANDING
SUPPLEMENTARY
HEATER
(where provided)
Fiat Ducato can be equipped, upon re-
quest, with two different self-standing
heaters: one is totally automatic whereas
the other is programmable.
AUTOMATIC VERSION
The supplementary heater will activate au-
tomatically with engine turned on and
proper engine coolant and outside tem-
perature conditions. Deactivation is always
automatic.
IMPORTANT During periods of low tem-
perature when the device is activated,
check that the fuel level is higher than the
reserve. Otherwise the device could lock
and require the assistance of the Fiat
Dealership.PROGRAMMABLE VERSION
The supplementary heater is totally inde-
pendent from the engine and can be used
to:
❒heat the passenger compartment
when the engine is off;
❒defrost the windows;
❒heat the engine coolant and conse-
quently the engine before starting.The system consists of:
❒diesel burner to heat coolant with ex-
haust fume muffler;
❒metering pump connected to the ve-
hicle fuel pipes to feed the burner;
❒heat exchanger connected to the en-
gine cooling system pipes;
The heater burns fuel in the
same way as the engine,
though, of course, to a lesser degree
and therefore to avoid intoxication
and suffocation, never use the sup-
plementary heater in closed areas,
garages or workshops not equipped
with specific exhaust evacuation de-
vices even for short periods of time.

In cold weather, the supplementary heater
warms and circulates constant tempera-
ture fluid in the engine cooling system for
the time required to ensure optimal en-
gine ignition and passenger compartment
temperature conditions.
The heater can be started automatically
(programmed by means of the digital
timer) or manually by pressing the “heat
now” button on the timer.
When the heater is turned on (automat-
ically or manually), the electronic control
unit operates the fluid circulation pump
and safely ignites the burner according to
preset and controlled modes.

heater/ventilation unit for automatic
operation;
❒electronic control unit to check and

❒digital timer A-fig. 54to start the
heater manually or to program staring
time.The electronic control unit also controls
the circulation pump delivery in order to
reduce initial heating time. When the sys-
tem is operating, the control unit operates
the heater unit fan to the second speed.
Thermal power is adjusted automatically
by the control unit according to the en-
gine coolant temperature.

IMPORTANT The heater is equipped with
a thermal switch which cuts off the heater
in the event of overheating caused by low
or leaking coolant. In this case, press the
program selection button to start the
heater again after repairing the cooling sys-
tem fault and/or topping up the fluid.
The heater can turn itself off after engine
ignition or if the flame goes out. In this
case, turn the heater off manually and at-
tempt to turn it back on again. If you can-
not turn the heater on, contact a Fiat
Dealership.Turning the heater on
If an automatic climate control system is
fitted, the control unit sets air tempera-
ture and distribution when the parking
heater is turned on.
When a manual heater/climate control
system is fitted, to achieve peak heater
performance, check that the passenger
compartment heater/ventilation unit air
temperature knob is in “warm air” posi-
tion.
For preferential passenger compartment
preheating, turn the air distribution knob
to position
©.
For preferential windscreen demisting, set
the air distribution knob to position
-.
To obtain both functions, set the air dis-
tribution knob to position

❒Always remember to turn the heater
off when refuelling or standing in ser-
vice stations to avoid fires and explo-
sions.
❒Do not park the vehicle over inflam-
mable material such as paper, dry grass
or leaves: fire risk!
❒The temperature near the heater must
never exceed 120°C (e.g. during paint-
ing operations in a workshop oven).
Higher temperatures could damage
the electronic control unit compo-
nents.
❒When the engine is off, the heater takes
power from the battery: it is conse-
quently important to run the engine for
a certain period of time in order to re-
store the battery charge.
❒Follow the prescriptions in section
“Vehicle maintenance” at paragraph
“Engine coolant level” to check the
coolant level. The coolant in the cir-
cuit must contain at least 10% an-
tifreeze fluid.
❒Maintenance and repairs must always
be carried out by a Fiat Dealership and
only genuine spare parts must be used.
MAINTENANCE
Have the heater checked at a Fiat Deal-
ership periodically (always before winter).
This will ensure safe and cheap running
and long appliance life.
The heater burns fuel in the
same way as the engine,
though, of course, to a lesser degree
and therefore to avoid intoxication
and suffocation, never use the sup-
plementary heater in closed areas,
garages or workshops not equipped
with specific exhaust evacuation de-
vices even for short periods of time.
WARNING
IMPORTANT The parking heater goes off
when the battery voltage is low to enable
the vehicle to be started up.
IMPORTANT Before turning on the de-
vice, ensure that the fuel level is higher
than the reserve. Otherwise the device
could lock and require the assistance of
the Fiat Dealership.
