. Thru-hull fittings
2. Seal bulkhead voids and openings at wiring and
piping runs in return air ducting, plenums, and air
handling equipment enclosures, especially those
adjacent to machinery compartment bulkheads.
8. Hangers and other supports
W. Maintenance - Ventilation Systems
Check that water traps and condensate drains are
present. These may be in the form of a double
loop in the drain line or prefabricated p-traps. Any
drain that discharges below the waterline when the
boat is underway is sealed, by virtue of its design,
against CO intrusion.
Boats are equipped with ventilation systems to elimi-
nate gasoline vapors. Blowers and fans may also be
provided for ventilation and to mitigate the migration of
CO into occupied compartments. Attention should be
paid to the following:
. Keeping ventilation intakes clear of debris
Z. Maintenance - Liquid Drains
. Replacing damaged hardware
Sink, shower and condensate drains can be a source
of CO ingress. Ensure that water traps are present
. Maintaining the integrity of the ducting material and and contain fluid. These traps may be in the form of a
double loop in the drain line or prefabricated p-traps.
Any drain that terminates below the waterline is, by vir-
tue of its design, sealed against CO intrusion. Some
. Ensuring that position of ducting intake is not ob-
structed or restricted, collapsed, kinked, or crushed drains that are below the waterline when boat is under-
way will be above the waterline when the boat is at rest.
5. Eliminating sags in ducting that can form a water
The location of drains, relative to the waterline, can be
affected by the dynamics of boat motion (i.e., under-
way or at rest).
Checking hangers and other supports
Ensuring blower/fan is operational
AA.CO Detection System
Four Winns provides CO monitor(s) on Sundowner™
models. Check system(s) regularly and maintain in ac-
cordance with the manufacturer’s instructions.
. Ensuring that airflow is present at discharge
Inspecting wiring to equipment
X. Maintenance - Bulkhead and Deck Integrity
CO monitors should be professionally installed
and calibrated. Failure to do so may result in
the improper function of the CO detector.
Seal all visible openings (e.g., cracks, crevices,
holes, including openings around wiring and piping
runs) in bulkheads and decks that separate ma-
chinery compartments from occupied compart-
ments. These openings can permit migration of
Never disarm a CO detector. If a CO detector
alarms, immediately ventilate the area and
check passengers for symptoms of CO intoxi-
cation. See your Four Winns dealer for assis-
tance in diagnosing the cause for the alarm.
Check gaskets and sealing surfaces on hatches,
doors, and access panels.
Y. Maintenance - Air Conditioning Systems

Manual) Section A-24, “Carbon Monoxide De-
These systems can be a source of CO ingress and
migration of CO vapors.
Keep grilles and filters clean.
