1 Introduction
The Vetus exhaust system components are especially suitable for use
in water-injected exhaust systems.
The maximum continuous operating temperature of the plastic
components of the exhaust systems is 70 degrees C (158-degrees F).
The LSG, LSL and LSS exhaust silencers have a very large capacity,
so that they are exceptionally suitable for use in systems with extra
long exhaust pipes. An extra large capacity exhaust silencer is of vital
importance for a sailing ship, which will roll and pitch in rough water
with the engine off!
The LSG-type exhaust silencer is also fitted with a non-return valve;
this virtually prevents any water entering the exhaust system. Water
entry can be caused by the ship pitching, waves from aft, or stopping
the ship quickly.
- Fit a temperature alarm to warn of excessively hot exhaust
system temperature.
- If the quantity of injected coolant water is reduced to in or-
der to lower back-pressure in the exhaust system, check that
there is still sufficient water injected when the engine is tick-
ing-over. This will prevent excess temperatures in the exhaust
system.
- Excess temperature can also be the consequence of insuffi-
cient mixing of coolant water with the exhaust gasses.
In general, good mixing is obtained by a virtually vertically
installed exhaust injection bend.
Poor mixing can also occur with an engine on tick-over; espe-
cially when the coolant water injection bend is installed virtu-
ally horizontally.
If necessary, take action. For example; by fitting a water vor-
tex or a water splitter in the exhaust pipe, to improve the mix-
ing of coolant water with the exhaust gasses.
With water-injected exhaust systems, fit a hose of suitable quality.
This hose must be reinforced, resistant to exhaust gasses, high tem-
peratures (100 degrees C, 212 degrees F) and oil.
Easy flexibility is essential for installation, while the hose must not
collapse when heated.
Vetus exhaust hose fulfils all the above requirements.

If water enters the engine from the exhaust silencer into the
exhaust system (for example: under sail when the ship rolls or
pitches heavily) this will lead to irreparable damage to the en-
gine.
The overall dimensions drawing shows the maximum amount
of water which can be contained in the exhaust silencer. Too
much water in the silencer can effect engine starting; drain
off this water first. Too much water in the silencer can be also
caused by repeated starting attempts while the engine refuses
to start.
2 Installation
2.1 Installing exhaust silencer LP, LSG, LSL and LSS
Instal the exhaust silencer as vertical as possible. In a sailing ship, the
exhaust silencer should also be installed as close to midships as pos-
sible; this will prevent water flowing from the silencer to the engine
when the ship heels over under sail.
The exhaust silencer 'IN'-connection must always remain below the
level of the exhaust injection bend! Position the silencer 'back-to-
front' alongside the engine when there is insufficient space behind
the engine.
During operation, the exhaust silencer will contain water. Its weight
will thus increase considerably, so fit the silencer with tension straps.
2.2 Installing the transom exhaust connection
Fit the transom exhaust connection at such a position that with the
ship fully laden, the transom connection is still at least 10 cm (4")
above the waterline.
In order to install the transom exhaust connection so that it remains
watertight, apply marine adhesive sealant between the flange of the
transom connection, and the transom.
The rubber transom exhaust connection TRCxxR, where xx stands for
the diameters of 40 mm (1 9/16"), 45 mm (1 3/4"), 50 mm (2"), 60 mm
(2 3/8"), 75 mm (3") and 90 mm (3
fitting the exhaust hose.
The maximum thickness of the transom where the transom connec-
tion is fitted, can be 40 mm (1 9/16") with this type, with the excep-
tion of the TRC7590R. With these, the maximum transom thickness is
20 mm (13/16") .
With the plastic transom exhaust connection TRCxxPV, xx stands for
diameters of 40 mm (1 9/16"), 45 mm (1 3/4"), 50 mm (2"), 60 mm (2
3/8"), 75 mm (3") and 90 mm (3
directly, without hose connector.
The maximum thickness of the transom at the place where the tran-
som connection is fitted, can be 35 mm (1 3/8") for type TRCxxPV and
TRCxxS.
