COMPARTMENT FLOOR CUTOUTS

You must provide openings in the generator compart

ment for the following items (Figure 18):

• Engine exhaust and cooling air outlets

• Generator cooling air inlet

• Four holes for passage of generator mounting bolts. See

“Generator Restraint” on Page 16.

Line the compartment interior walls and floor, as well as

the underside of the floor, with 26-gauge galvanized steel.

Vapor seal all compartment seams and joints.

Over the galvanized steel lining, install a selected combi

nation of acoustical materials as mentioned in “Sound

Insulating Materials.”

DANGER: Fuel lines and exhaust piping must not

penetrate into vehicle living area.

ACOUSTICS

If excessive noise levels should become a problem,

the installer may wish to consider the following:

• Using special sound insulating materials.

• Construction of a special noise abatement compartment.

IMPORTANT: ANY METHOD USED TO REDUCE

NOISE MUST NOT ADVERSELY AFFECT THE

FLOW OF COOLING AND VENTILATING AIR INTO

OR OUT OF THE COMPARTMENT.

In addition to the effective use of sound insulating

materials, construction of a special noise abatement

compartment might be considered to reduce noise

levels. Such a compartment might be constructed as

follows (Figure 19):

• Use 5/8-inch thick or 3/4-inch thick plywood in the com

partment.

• Construct the compartment floor of a double thickness of

5/8-inch or 3/4-inch plywood.

DANGER: Do not install any insulation or other

absorbent materials on the interior or underside of

the compartment.

Seal all compartment door edges to prevent noise leak

age around the door perimeter.

Line the compartment door interior (except for air open

ings) with suitable, fire proof sound insulation (such as 1-

inch thick fiberglass with a 2-pound density).
