GENERATOR RESTRAINT
Use four 3/8"-16 hardened steel bolts (Grade 5) to fas­
ten the generator to the supporting frame or the sup­
port tubing. These bolts must pass through (a) the
generator mounting base, (b) the compartment floor, if
a compartment is used, and (c) the supporting frame­
work (Figure 16). All bolts must be long enough so that
when tight, at least 3 threads are visible past the
retaining lock nuts. Refer to “COMPARTMENT’ section
for location of generator mounting holes.

GENERATOR COMPARTMENTS
COMPARTMENTS
The generator set may or may not be installed inside a
compartment that is constructed specifically for hous­
ing a generator. This section applies to generator com­
partments when they are installed. The following gen­
eral rules apply to compartments;
• The generator compartment should be either con­
structed of, or lined with, 26 gauge galvanized
steel.
IMPORTANT: ALUMINUM IS NOT AN ACCEPTABLE
ALTERNATIVE TO GALVANIZED STEEL, DUE TO
ALUMINUM'S LOW MELTING POINT.
• If the compartment Is lined with galvanized steel, it
may be constructed of any material. Generac rec­
ommends that the compartment be constructed of
1/2-inch thick plywood, with the floor made of a
double thickness of plywood for added strength.
• All seams, splices and joints of the compartment
walls (unless vapor tight by design) should be
caulked.
IMPORTANT: CAULKING MUST BE DONE SO THAT
THE CAULKING MATERIAL WILL STAY IN PLACE
PERMANENTLY. PRESSING SUCH MATERIALS AS
PUTTY TAPE ONTO JOINTS AND SEAMS WILL NOT
MEET THAT REQUIREMENT. A HIGH QUALITY SILI­
CONE RUBBER SEALANT IS RECOMMENDED.
Holes and opening
ssaqe of
s through the compartment
electrical conduit, conductors.
walls for passage
etc, into vehicle living area must be sealed vapor-
tight with silicone rubber base sealant.
If you use flexible metal conduit, seal the conduit
at the end where it terminates inside the junction
box. Flexible metal conduit is NOT vapor tight
along its entire length.
Seams and joints of the galvanized steel (whether
used as a liner or the compartment itself) must be
lapped and mechanically secured. Such seams
may be manufactured, welded, bolted, riveted, or
screwed. Manufactured lock seams are shown in
Figure 16.
