The VTE S.r.l. warranty does not cover errors and inaccuracies in the installation of the exhaust line.
VTE S.r.l.
recommends the installation of an exhaust system having in-line mufflers.
The in-line water-lock muffler must first muffler must be installed below the generator, in order to avoid water
return/entrance into the engine. It must accumulate any water that runs back down the exhaust line after the
engine is shut down. Design the system so there is an adequate drop in the line between the exhaust manifold
and the thru-hull discharge end of the line. The exhaust hose must be certified for marine use.
WARNING! An exhaust line that is too long and/or has an incorrect slope can cause water to return to
the engine when the generator is shut down.
The exhaust line connections must be secured in such a way as to avoid any dripping.
The exhaust gases are fatal. Install a carbon monoxide warning near the generator and in a clearly
visible position.
5.5.1 Traditional system
The best noise dumping result is obtained fitting the 3 typical exhaust mufflers:
-
the first
, as water-lock
avoids the risk of water return into the engine and reduces the acoustic
emission by 50%;
-
the second reduces a further 20% noise and must be fitted with a gradient towards the outlet in order
to avoid water return;
-
the third dumps a further 10% and avoids the risk of external seawater entrance due to waves.

Traditional Plant diagram
Water exhaust separator: it is possible to reduce the noise of the exhaust line installing a water-exhaust
separator as per the following image. In this case, the exhaust gas output is separated from the water output,
so that the typical splash of the water (of the traditional exhaust lines) is eliminated.
