Exhaust System - Westerbeke 8.0KW BCDT60Hz Owner's Manual

INSTALLATION
EXHAUST SYSTEM
It
is important to install a proper exhaust system to avoid engine
flooding. The system must be designed to prevent water from
entering the exhaust line under any sea conditions and at any
angle of the vessel's hull. Exhaust system failures are not covered
by Westerbeke's warranty. The installer should have a basic
knowledge of marine installation requirements.
Westerbeke recommends installing an exhaust system having an
in-line mufller (see illustration). The in-line mufller should be
located below the engine's exhaust elbow. 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 elbow and the through-hull discharge end of
the line. The exhaust hose must be certified for marine use. Use
the following illustrations as a general guide when installing an
exhaust system.
A
CAUTION:
An exhaust line that is too long and/or
has
a
poor gradient can cause water to return back to
the generator's engine when the generator is shut off.
Westerbeke Corporation presumes that the installer of this marine
diesel generator is familiar with the safeguards a water-cooled
marine exhaust system will provide for the engine. Failure to
design and layout a proper exhaust system can result in
catastrophic damage to the diesel engine, and possibly result in the
sinking of the vessel in which the unit is installed.

Carbon Monoxide
The best protection against carbon monoxide poisoning is a daily
inspection of the complete exhaust system. Check for leaks
around manifolds, gaskets, and welds. Make sure exhaust lines
are not heating surrounding areas excessively. If excessive heat is
present, correct the situation immediately. If you notice a change
in the sound or appearance of the exhaust system, shut down the
unit immediately and have the system inspected and repaired at
once by a qualified mechanic.
A
WARNING:
00 not install thl! exhaust outlet near
a
swim platform! When people are in the water or in
a
dinghy near the boat shut the generator or engine down.
A carbon monoxide warning decal has been provided by
Westerbeke. Display this decal near your engine or generator, on
your cabin bulkhead, or in some other prominent location.
NOTE: It is extremely important that a carbon monoxide
detector(s) be installed in your boat
s
living and/or sleeping
quarters. Make sure it is manufactured for the marine industry.
They are inexpensive and easily available at your marine supplier.
