Exhaust Systems; General - Kohler 13.5CCOZ Operation And Installation Manual

WARNING
Carbon monoxide.
Can cause severe nausea, fainting, or death.
The exhaust system must be leakproof and
routinely inspected.
Inspecting exhaust system. Carbon monoxide can
cause severe nausea, fainting, or death. In addition
to routine exhaust system inspection, install a carbon
monoxide detector. Consult your boat builder or dealer
for approved detector installation. Inspect your detector
before each generator set use.
Operating generator set. Carbon monoxide can
cause severe nausea, fainting, or death. Use the
following precautions when installing and operating
generator set. Carbon monoxide is an odorless,
colorless, tasteless, nonirritating gas. Be especially
careful if operating the generator set when moored or
anchored under calm conditions as 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— make sure your exhaust is directed
away from other boats and buildings. Do not install
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. Avoid overloading the craft.
6-12 Installation

Exhaust Systems

Use water-cooled exhaust lines in all marine
installations. Keep the lines as short and straight as
possible. ABYC Safety Standards P-1.6.i. recommends
using two corrosion-resistant hose clamps, with a
minimum width of 1/2 in. (13 mm), on each end of flexible
exhaust hose connections A pitch of at least 1/2 in. (13
mm) per running foot (30.5 cm) is preferred. Use flexible
exhaust hose conforming to U.L. Standard 1129 for
engine wet exhaust components between mixing elbow
and exhaust outlet. Independently mount the silencer to
eliminate any stress on exhaust system and exhaust
manifold/mixer elbow. See Section 1— Specifications
for mixing elbow water line hose size. See Figure 6-13
for exhaust connection to mixer elbow.
