Generac Power Systems 00862-1 - Manual (Page 18)

GENERATOR RESTRAINT
Use four 3/8"-16 hardened steel bolts (Grade 5) to
fasten the generator to the supporting frame or the
support tubing. These bolts must pass through (a) the
generator mounting base, (b) the compartment floor,
if a compartment is used, and (c) the supporting
framework (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
The generator set may or may not be installed inside
a compartment that is constructed specifically for
housing a generator. This section applies to generator
compartments when they are installed. The following
general rules apply to compartments:
• The generator compartment should be either
constructed of, or lined with, 26 gauge galvanized
steel.
IMPORTANT: ALUMINUM IS NOT AN ACCEPT­
ABLE 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 openings through the compartment
walls for passage of electrical conduit, conduc­
tors, 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, bolt­
ed, riveted, or screwed. Manufactured lock
seams are shown in Figure 17.
