THE EXHAUST PIPES WILL BE VERY HOT AND ALL
ACCESSIBLE
PIPES
AND
MUFFLERS
ARE
DANGEROUS TO PEOPLE WHEN NOT INSULATED.
There are companies that are specialised in insulating hot pipes
and fancy systems are available to make it good looking.
However it is also possible to do it yourself by winding
fibreglass or Rockwool around the pipes and seal it with
aluminium tape. On request Whisper Power can supply
insulation jackets for all king of pipes and bends.

THE STANDARD DRY EXHAUST SYSTEM
The standard exhaust system contains:
On the Genverter:
An insulated exhaust bend
In the exhaust installation kit:
A stainless steel shielded flexible bellow.
One resonance muffler
One absorption muffler
Clamps and rubbers to mount the system flexible
Fittings, bends and pipes to make the different
connections
Jackets for thermal and sound insulation.
The mufflers are high quality marine mufflers that are much
more effective, robust and durable than mufflers made for
automotive use.
WHEN THE EXHAUST IS LED THROUGH THE SIDE,
DECK OR ROOF OF THE DECK HOUSE, MEASURES
HAS TO BE TAKEN TO PREVENT RAINWATER TO
ENTER THE SYSTEM. SPECIAL RAIN CAPS ARE
AVAILABLE AS AN OPTION.
INSTALLATION OF THE DRY EXHAUST
Before determining the location of the Genverter set one has to
consider how to get away with the exhaust. In wind still
conditions a light smell of exhaust fumes around the boat will
not be avoidable.
To bring the exhaust to the deck or to the top of the deck house
gives the best results on noise and smell. However, when the
pipes go through the boat they should be insulated and around
the hole in the deck or roof should be a collar to prevent
rainwater to leak in. Both mufflers could be on the roof or one
of them or both could be in the machine room.
In general it is better to have the mufflers wide apart: the
resonance muffler close to the Genverter and the absorption
muffler on the end of the line. A short pipe (30cm) should be on
the far end after the absorption muffler. The absorption muffler
has no flow direction and could be mounted both ways. The
resonance muffler should be mounted according to the
indication on the muffler itself.
The resonance muffler should be fitted according
to direction of the gas flow indicated.
In the kit are clamps to mount the exhaust pipes to stainless
steel bars. These bars should be mounted to the structure of
the boat. It is recommend to use rubber mountings whenever
possible. However take care that the heat conducted through
the brackets will not affect the rubber. Refer to Figure 17 how
to mount the rubber in a safe way. When any doubt an extra
safeguard could be constructed from steel wire or chain.
