Conducting the exhaust gas
The exhaust gas pipe must not protrude beyond the
external limits of the vehicle.
The exhaust pipe must either slope downwards
slightly, or a 5 mm diam. hole must be drilled into the
lowest point of the pipe to allow condensate to drain
off.
Always fasten the silencer; longer exhaust pipes must
always be fastened at intervals of approx. 50 cm.
Arrange the exhaust gas outlet in such a manner
that the exhaust gas cannot be immediately drawn in
again.
The exhaust gas outlet must lead out into the open
air.
The exhaust gas pipe must be arranged in such a
manner that exhaust gas cannot enter the vehicle,
be drawn in by the vehicle's fan or by the heater
fan
1)
, nor must it impair the function of vital vehicle
parts in any way (ensure that an adequate distance
is maintained).
Run the exhaust gas pipe in such a manner that
it cannot be clogged up by dirt, snow or water (drain-
ing hole).
Do not direct the outlet of the exhaust gas pipe
against the air-stream.
At the outlet of the exhaust gas pipe, the terminal
sleeve with web provided for must have been
mounted (statutory regulation).
1)
This requirement is considered to be fulfilled when the end of
the exhaust gas pipe is run upwards or to the side, or when
the exhaust gas pipe passes underneath the vehicle floor to
the vicinity of the side or rear limits of the driver's cab or the
passenger compartment.
Exhaust gas can possibly reach far more than
(on average) 280 °C at the outlet of the
AIRTRONIC
(in case of the malfunction ‘overheating’ up to max.
400 °C).
Due to this, the entire exhaust gas duct gets very
hot and thus has to be laid and mounted such that
there is always sufficient clearance to heat-sensitive
components. Special attention needs to be paid to
fuel lines (plastic or metal) and electric wiring both
on the vehicle and on the heater side as well as
to brake hoses and similar parts!
Exhaust gas pipes need to be securely fastened
to avoid damage resulting from vibrations
(recommended guideline: spaced approx. 50 cm).
ATTENTION!
Danger of poisoning and burns!
Every combustion process creates exhaust gas
which contains toxic constituents; for this reason
and due to the high temperatures occurring, the
exhaust gas duct needs to be absolutely carried out
in accordance with the specifications of these
mounting instructions.
During heating operation, avoid any work in the area
of the exhaust gas duct.
In such a case, switch off the
AIRTRONIC
beforehand and wait until all parts have completely
cooled down.
If necessary, wear protective gloves.
