Section 4 Exhaust System
Operating the generator set. Carbon monoxide can cause
severe nausea, fainting, or death. Carbon monoxide is an
odorless, colorless, tasteless, nonirritating gas that can cause
death if inhaled for even a short time. Use the following
precautions when installing and operating the generator set.
Do not install the exhaust outlet where exhaust can be drawn
in through portholes, vents, or air conditioners. If the generator
set exhaust discharge outlet is near the waterline, water could
enter the exhaust discharge outlet and close or restrict the flow
of exhaust.
Never operate the generator set without a
functioning carbon monoxide detector. Be especially careful if
operating the generator set when moored or anchored under
calm conditions because gases may accumulate. If operating
the generator set dockside, moor the craft so that the exhaust
discharges on the lee side (the side sheltered from the wind).
Always be aware of others, making sure your exhaust is
directed away from other boats and buildings.

4.1 Types
Kohlerr generator sets covered in this manual use
either wet or dry exhaust systems. Dry exhaust systems
are common in commercial applications.
engine manual for specifications.
4.2 Exhaust Lines
Use water-cooled exhaust lines in all marine
installations. Keep the lines as short and straight as
possible.
NFPA 302 Fire Protection Standard for
Pleasure and Commercial Motor Craft, Clause 4-3,
recommends using two corrosion-resistant hose
clamps with a minimum width of 13 mm (1/2 in.) on each
end of the flexible exhaust hose connections.
Kohler Co. requires a downward pitch of at least 13 mm
per 30.5 cm (1/2 in. per running foot). Use a flexible
exhaust hose that conforms to UL Standard 1129 for the
engine's wet exhaust components between the mixer
elbow and the exhaust outlet.
