Ventilation - Kohler 13.5CCOZ Operation And Installation Manual

Ventilation

WARNING
Explosion.
Gasoline vapors can cause explosion and
severe injury or death.
Before starting generator set, operate blower 4
minutes and check engine compartment for
gasoline vapors.
Engine combustion, generator cooling, and expulsion of
flammable and lethal fumes require ventilation.
Ventilation provisions must comply with USCG
Regulations governing sizing of vents and operator
requirements.
As a rule, size each inlet- and outlet-vent area to a
minimum of 2 sq. in. per ft. (13 sq. cm/30.5 cm) of craft' s
beam. Should this rule in any instance conflict with
USCG Regulations, follow Regulations. If using any
screen in inlets, double the size of hull/deck openings.
Extend vent ducts to bilges to expel heavier-than-air
fumes. For generator sets mounted in the engine
compartment, increase air flow to allow for generator
set' s requirements. Install optional sniffer devices to
cause alarm, warning, or engine shutdown should
dangerous fumes accumulate in the compartment.
6-4 Installation
Figure 6-2 lists air requirements for various models.
The air intake silencer/cleaner provides combustion air
to the engine. Do not compromise the recommended
minimum clearance of 1.5 in. (38mm) between duct
opening and any enclosure wall. Not following these
guidelines will adversely affect engine/generator
performance.
