reduced to non-hazardous values) and excessive

discharged as fast as possible when the temperature
exceeds 110°C).

switch).

The Natural Power Fiat Multipla features the same
passive safety characteristics as the other versions.
In particular, the natural gas bottle position and
mounts have been designed so as to pass the crash
tests in accordance with the Fiat safety standards.
The flow of the natural gas coming out of the bottle is
regulated by a solenoid valve that is open only when
the engine is fuelled by natural gas.
The solenoid valve unit includes the protections in
case of excessive flow (in the event that the high
pressure system is broken, the natural gas flow will be
WARNINGThe Natural Power Fiat Multipla is equipped with a high-pressure natural gas
system designed to operated at 200 nominal bar.
It is dangerous to force the system with higher pressures. When the vehicle has to
be towed or lifted, strictly follow the instructions of the basic handbook (refer to
“Towing the vehicle”), to avoid damaging the natural gas system components.
In case of natural gas system failure, contact the Fiat Dealership only.
Do not modify the natural gas system configuration or components: they have
been especially designed for Natural Power Fiat Multipla only. Using other
components or materials may cause vehicle malfunction and affect the vehicle’s
safety. In case of “furnace” painting, the bottles shall be removed from the vehicle
and subsequently fitted back into place by the Fiar Dealership.
Although the natural gas system is equipped with various safety devices, it is
recommended that the manual tap of every single bottle is turned off every time
the vehicle is either put away for a long time or transported on other vehicles or
operated in emergency situations following a failure or accident.

SAFETY DEVICES/SOLENOID VALVE
A solenoid valve has been screwed onto each bottle, which cuts off the
natural gas flow towards the engine feed circuit.
The solenoid valve is open when:
❐the switching button is in the “Natural gas” position
❐the pressure inside the bottle is enough for functioning
❐the engine is running
❐the inertia switch has not tripped.
The solenoid valve unit features the following safety devices:
1) Fuse plugnut: in case of anomalous overtemperature (higher than
110°C), this device will fully eliminate any overpressure hazard by
causing the natural gas contained in the bottle to flow outwards as fast
as possible.
2) Excessive flow: this device comes into operation in case of pipe
breakage, by reducing the natural gas outgoing flow to non-hazardous
values. The flow relief valve is placed in such a position that it can
operate even when the solenoid valve body is broken following a
collision.
3) Manual cock: it is positioned upstream the solenoid valve.
It separates the bottle from the natural gas system to allow the
maintenance operations to be carried out.
To turn cock (A) off, rotate clockwise (position 1).
To turn the cock on, rotate counterclockwise (position 2).
4) Non-return valve, positioned on the pipe running from the filling pipe
union, to prevent the natural gas from flowing back.F0E0572m
