OTHER FEATURES
operated independently of the heater by means
of an appropriate circuit. The heater can be
switched
ON
at any time (i.e., during the delayed
cut-out period). Ignition takes place after the
delayed cut-out time expires.
SWITCHING THE HEATER OFF
The fuel supply is interrupted when the heater is
switched
OFF
. This causes the flame to go out
and a delayed cut-out of 2.5 minutes begins.
The circulating combustion air flushes the
remaining combustion gases out of the chamber
and cools off the heated parts on the exhaust
side of the heat exchanger. The water
circulation pump continues to transfer the latent
heat present in the heat exchanger, thus
preventing hot spots. Once the delayed cut-out
time expires, both the combustion air blower and
the water circulation pump switch
OFF
automatically. A cut-out will automatically take
place in case of heater failure. Refer to chapter
8, "Technical Information" for more information.
COOLANT HEATER TIMER
The timer, located on L.H. lateral console is used
to program the starting and stopping time of the
preheating system. One of three possible timers
may be installed in your vehicle (refer to the
three following images). The system indicator
light, located on the timer, illuminates when the
system is functional.
Caution:
The preheating system should not
operate for more than one hour before starting
engine as this could discharge batteries.
Warning:
Preheating system must not
operate when vehicle is parked inside or during
fuel fill stops.
Note:
Preheating system uses the same fuel
as the engine.
