Other Location Requirements
Place the standby generator in a prepared location
that is flat and has provisions for water drainage.
Install the standby generator in a location where
sump pump discharge, rain gutter down spouts, roof
run-off, landscape irrigation, or water sprinklers will
not flood the unit or spray the enclosure, or enter any
air inlet or outlet openings.
Install the standby generator where it will not affect
or obstruct any utility services (including covered,
concealed, and underground), such as telephone,
electric, fuel (natural gas / LPG vapor), irrigation, air
conditioning, cable, septic, sewer, well, etc.
Install the standby generator where leaves, grass,
snow, etc will not obstruct air inlet and outlet
openings. If prevailing winds will cause blowing or
drifting, a windbreak may be needed to protect the
unit.
Electrical and Fuel Inlet Locations
A through-slab power cable stub-up is recommended. The
fuel inlet connector (A) is shown for reference.
Concrete Slab
The generator must be installed on a reinforced concrete
slab, constructed as follows:
28 day compression strength of 3000 psi (200 MPa)
Minimum 5” (13 cm) thick
Minimum 6” (15 cm) wider than the standby enclosure
on all sides
Strengthen slab with No. 6 reinforcing bars on 12” (30.5
cm) centers or 8 ga. steel wire fabric with 6” (15 cm)
centers
Avoid placing reinforcement in the entrance stub-up
area
The following dimensions will be needed to properly size and
configure the slab. Refer to figure at right:

wide
40/48kW = 10.5” (27 cm) long x 6.75” (17 cm) wide
50/60kW = 6.0” (15 cm) long x 5.25” (13 cm) wide
D1 x D2 - Entrance stub-up location
29/35kW (3.0L) = 6.0” (15 cm) x 7.75” (20 cm)
29/35kW (4.3L) = 8.5” (22 cm) x 7.75” (20 cm)
