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.

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:
A - Enclosure dimensions
• 70" (178 cm) long x 30" (76 cm) wide
A1 - Roof overhang dimensions
• 71" (180 cm) long x 32.3" (82 cm) wide
B - Generator mounting holes
• 68" (172.7 cm) long x 27.7" (70.4 cm) wide
B1 - Mounting holes diagonal measurement
• 73.4" (186.5 cm)
C - Fuel inlet location
• 18.9" (48 cm)
D - Wire entry location
• 7.4" (18.8 cm)
