14 Installation Guidelines for 60 Hz Air-Cooled Generators
See Figure 3-1. Install the generator set, in its protective
enclosure, outdoors where adequate cooling and
ventilating air is always available. Consider these factors:
• The installation of the generator must comply
strictly with ICC IFGC, NFPA 37, NFPA 54, NFPA
58, and NFPA 70 standards.
• Install the unit where air inlet and outlet openings
will not become obstructed by leaves, grass, snow,
etc. If prevailing winds will cause blowing or
drifting, consider using a windbreak to protect the
unit.
• Install the generator on high ground where water
levels will not rise and endanger it. This unit should
not operate in, or be subjected to, standing water.
• Allow sufficient room on all sides of the generator
for maintenance and servicing. This unit must be
installed in accordance with any local, state, or
national codes for minimum distances from other
structures.
• Clearance from the ends and front of the generator
must be 3 ft (0.91 m). This includes shrubs,
bushes, and trees. Clearance from the back of the
generator must be a minimum of 18 in (457 mm).
Clearance at the top should be a minimum of 5 ft
(1.52 m) from any structure, overhang, or
projections from the wall.
IMPORTANT NOTE: Mechanical and gravity outdoor
air intake openings for HVAC supply air systems
shall be located not less than 10 feet (3048mm)
horizontally from the generator enclosure. See
Section 401 in the ICC Mechanical Code for any
additional requirements.
• DO NOT install under wooden decks or structures
unless there is at least 5 ft (1.52 m) of clearance
above the generator.
• Install the unit where rain gutter down spouts, roof
run-off, landscape irrigation, water sprinklers, or
sump pump discharge does not flood the unit or
spray the enclosure, including any air inlet or outlet
openings.
• Install the unit where services will not be affected
or obstructed, including concealed, underground,
or covered services such as electrical, fuel, phone,
air conditioning, or irrigation. This could affect
warranty coverage.
• Where strong prevailing winds blow from one
direction, face the generator air inlet openings to
the prevailing winds.
• Install the generator as close as possible to the fuel
supply to reduce the length of piping. REMEMBER
THAT LAWS OR CODES MAY REGULATE THE
DISTANCE AND LOCATION. In the absence of
local codes regarding placement or clearance, we
recommend following these guidelines:
– Install the generator as close as possible to the
transfer switch. REMEMBER THAT LAWS OR
CODES MAY REGULATE THE DISTANCE
AND
LOCA
TION.
– The generator must be installed on a level
surface. The generator must be level within a 0.5
in (13 mm) all around.
– The generator is typically placed on pea gravel,
compacted soil, crushed stone, or a concrete
pad. Check local codes to see what type is
required. If a concrete pad is required, all
applicable codes should be followed.
Verify Wi-Fi Range
Refer to the Wi-Fi manual shipped with the unit if
planning to use the Wi-Fi feature.
Installation Guidelines for Stationary Air-Cooled
Generators
See Figure 3-1. NFPA 37 is the The National Fire
Protection Association’s standard for the installation and
use of stationary combustion engines. Its requirements
limit the spacing of an enclosed generator set from a
structure or wall.
NFPA 37, Section 4.1.4, Engines Located Outdoors:
Engines, and their weatherproof housings if provided,
installed outdoors shall be located at least 5 ft (1.52 m)
from openings in walls and at least 5 ft (1.52 m) from
structures having combustible walls. A minimum
separation shall not be required where the following
conditions exist:
1. The adjacent wall of the structure has a fire
resistance rating of at least one hour.
2. The weatherproof enclosure is constructed of
noncombustible materials and it has been
demonstrated that a fire within the enclosure will
not ignite combustible materials outside the
enclosure.
