INSTALLATION
When installing WESTERBEKE engines and generators it is important that strict
attention be paid to the following information:
CODES AND REGULATIONS
Strict 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
minimum of 20" above the vessel's waterline. Failure to use a siphon-break when
the exhaust manifold injection port
is
at or below the 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 the vessel's various operating conditions, install a
siphon-break.
NOTE:. A siphon-break requires periodic inspection and cleaning
to
ensure proper
operation. Failure to properly maintain a siphon-break can result in catastrophic
engine damage. Consult the siphon-break manufacturer for proper maintenance.
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 vessels hull.
Carefully review the Marine Installation manual provided with your
WESTERBEKE Engine or Generator.
Additional manuals are available from your WESTERBEKE dealer.
