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.
