the craft’s occupants, install a carbon monoxide detector.
Never operate the generator set without a functioning carbon
monoxide detector. Inspect the detector before each
generator set use.
At the interval specified in the service schedule, inspect
the exhaust system components (exhaust manifold,
mixing elbow, exhaust hose, hose clamps, silencer, and
outlet flapper) for cracks, leaks, and corrosion.
Ensure that the carbon monoxide detector(s) is (1) in the
craft, (2) functional, and (3) energized whenever the
generator set operates.
For your safety: Never operate the generator set
without a functioning carbon
monoxide detector(s) f or your

Exhaust System Inspection Points
Check for exhaust leaks and blockages. Check the
silencer and piping condition and check for tight exhaust
system connections.
D Check the hoses for softness, cracks, leaks, or dents.
Replace the hoses as needed.
D Check for corroded or broken metal parts and replace
them as needed.
D Check for loose, corroded, or missing clamps.
Tighten or replace the hose clamps and/or hangers as
needed.
D Check that the exhaust outlet is unobstructed.

(blowby). Check for carbon or soot residue on
exhaust components. Carbon and soot residue
indicates an e xhaust leak. Seal leaks as needed.
