Installation manual

INSTALLATION
When installing WESTERBEKE engines and generators, it is important that strict
attention
be paid to the following information:
CODES AND REGULATIONS
Federal regulations, ABYC guidelines and safety codes must be complied with when
installing engines and generators in a marine environment.
SIPHON-BREAK
For installations where the exhaust manifold/water-injected exhaust elbow is close to or
will be below the vessel's waterline, provisions must be made to install a siphon-break
in the raw water supply hose to the exhaust elbow. This hose
must be looped a mini-
mum
of 20 in. (51 cm) above the vessel's waterline. Failure to use a siphon-break
when the exhaust manifold injection port is at or below the load waterline will result
in raw water damage to the engine and possible flooding of the boat.
If you have any doubt about the position of the water-injected exhaust elbow relative to
the vessel's waterline under any
of the vessel's various operating conditions or when
the vessel is not underway,
install a siphon-break. This precaution is necessary to pro-
tect your engine.
NOTE: A siphon-break requires periodic inspection and cleaning to ensure proper oper-
ation. Failure to properly maintain a siphon-break can result in catastrophic engine
damage. Consult the siphon-break manufacturer
for a proper maintenance schedule.
EXHAUST SYSTEM
The exhaust hose must be certified for marine use. The system must be designed to
prevent water from entering the exhaust under any sea conditions and at any angle
of
the vessel's hull.

engines and generators, is available from your WESTERBEKE dealer.
