DRY EXHAUST INSTALLATION
a) An engine correctly installed in accordance with this
handbook will meet the emission requirements of the
RCD (see back of manual).
b) Keep exhaust systems to a minimum length and
have gradual bends, refer to 'exhaust back pressure'
bottom of page 16 for futher information .
c) The dry exhaust system installed in a canal boat
or work boat should be 1
diameter.
The engine is fitted with a 1
stub as standard - Valid for exhaust systems up to
3 metres in length. A flexible exhaust bellows and
dry exhaust silencer should be used. It is up to
the installer to work out his own pipe run but care
should be taken as follows:

• Never use a flexible exhaust bellow as a bend, it will
crack, always keep them straight.
• Ensure that rain water (or any other water - say from
the side of the loch) cannot enter the exhaust port
and run back down the system, flooding the silencer
and eventually the engine (see drawings below).
• The system should be lagged if there is any danger of
the crew getting near it.
• A dry exhaust system will give off considerable heat
and suitable insulation and ventilation must be
provided.
