Kohler 20--2800 kW manual Air Vent

4.5 Air Vent

The air vent system is used on some air-cooled gas and has been used on some diesel models. It includes special ductwork which directs the flow of heated air to the outlet at the top or side of the engine. The air vent air flow is not reversed as it is with the Air-Vac system. Choose top or side outlet of the engine. Additional

ductwork connects to the engine ductwork carrying the heated air outside. For duct dimensions, refer to the dimensional drawing for the particular unit. This system is also efficient in maintaining consistent operating temperatures in confined areas. See Figure 4-7.

Note: Air vent requires very little engine modification making it practical for field installation.
