Adequate ventilation is vital for safety as well as proper operation
of the engine. Systems without adequate cooling may experience
stalling, premature oil deterioration, increased oil consumption,
power loss, and reduced life or failure of the engine and/or
compressor.
If the compressor overheats, the temperature switch will shut down
and disable the engine until the oil temperature drops below 140 °C
(284 °F).
During operation, the G300004 generates a considerable amount of heat that
must be evacuated away from the unit for it to run efficiently. The engine is air
cooled and requires an adequate supply of cool fresh air to cool the engine and
allow proper fuel combustion.
Ensure there is a minimum of 6 in of clearance between the engine air intake (the
recoil starter area) and any other components mounted on the vehicle. The WHASP
cooler fan should have a minimum of 12 in of clearance in front of it, however
unobstructed venting to open atmosphere is preferred.
The engine exhaust must be vented away from the G300004 and toward a
safe location (the exhaust tip can be rotated to change the exhaust direction if
needed). If mounted in an enclosure (such as a cabinet, or the bed of a pickup
truck box), the exhaust must be vented outside of the vehicle to prevent the gas
engine from ingesting its exhaust and overheating or stalling (Figure 1).
Exhaust and waste heat from the G300004 system must be vented
away from the system to prevent the gas engine from ingesting its
exhaust and stalling.
Ventilation Requirements
If mounted in an enclosure, special consideration must be made to
ensure adequate ventilation. See “Enclosed Mounting” on page 16
for more information.
