LISTED
Generac's Smart Power Management System is designed to optimize the performance of a standby generator. The system can consist of up to 8 individual
Smart Management Modules (SMM). Unlike other load management systems that depend on another control device, the SMM modules are actually self -aware
and operate autonomously.
Frequency is the true measure of generator engine performance and does not need to factor In increased ambient temperatures; elevation changes or generator fuel
type. The modules monitor the frequency (Hz) of the power being produced by Generac's standby generators. If frequency falls below a certain threshold, the
module will automatically follow a power management algorithm to reduce the chance of a generator overload condition.
The modules can be set to a load priority between 1-8, or be set in a lock -out only mode for loads that Just simply do not need to run in an outage. This reduces
the minimum size of the generator fora more cost-effective solution.

Site Selection and Preparation
Potential CO Entry Pointe
See Figure 3-1. Generator exhaust can enter a structure
through large openings, such as windows and doors.
However, exhaust and CO can also seep into the
structure through smaller, less obvious openings.
Protect the Structure
Verify structure itself is correctly caulked and sealed to
prevent air from leaking in or out. Voids, cracks, or
openings around windows, doors, soffits, pipes, and
vents can allow exhaust gas to be drawn into the
structure.
Some examples of potential entry points are described
and included in, but not limited to, the accompanying
table.

1a Installation Guidelines for 60 Hz Air -Cooled Generators
Site Selection and Preparation
Fire Prevention
The generator must be installed at a safe distance away
from combustible rnatersls. Engine, alternator, and
exhaust system components become very hot during
operation. Fire risk increases if unit is not correctly
ventilated, is not correctly maintained, operates too close
to combustible materials, or if fuel leaks exist. Also,
accumulations of flarnmabie debris within or outside the
generator enclosure may ignite.
Distance Requirements
See Figure 3-2. Minimum clearances must be
maintained around the generator enclosure. These
clearances are primarily for fire prevention, but also to
ensure sufficient room for removing front and end panels
for maintenance purposes.

Site Selection and Preparation
Fire Codes, Standards, and Guidelines
Generator installation must comply strictly with ICC
IFGC, NFPA 37, NFPA 54, NFPA 58, and NFPA 70
standards. These standards prescribe the minimum safe
clearances around and above the generator enclosure.
NFPA 37
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, and require generator to be located where it is
readily accessible for maintenance, repair, and first
responders.
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 resis-
tance rating of at least one hour.
2. The weatherproof enclosure is constructed of non-
combustible materials and it has been demon- .
strated that a fire within the enclosure will not ignite
combustible materials outside the enclosure.
Annex A —Explanatory Material
A4.1.4 (2) Means of demonstrating compliance are by
means of full scale fire test or by calculation procedures.
Because of the limited spaces frequently available for
installation, it has become apparent that exception (2)
would be beneficial for many residential and commercial
installations. The manufacturer contracted with an
independent testing laboratory to run full scale fire tests.
NOTE: The Southwest Research Institute (SwRI) is a
nationally recognized third party testing and listing
agency. SwRI testing approves 18 in (457 mm) installa-
tion minimum from the rear panel of the generator to an
adjacent structure for fire protection.
The criteria was to determine the worst case fire scenario
within the generator and to determine the ignitability of
items outside the engine enclosure at various distances.
The enclosure is constructed of non-combustible
materials, and the results and conclusions from the
independent testing lab indicated that any fire within the
generator enclosure would not pose any ignition risk to
nearby combustibles or structures, with or without fire
service personnel response.

Based on this testing and the requirements of NFPA 37,
Sec 4.1.4, the guidelines for installation of the generators
listed above are changed to 18 in (457 mm) from the
back side of the generator to a stationary wall or building
For adequate, maintenance and airflow clearance, the
area above the generator should be at least 5 ft (1.52 m)
with a minimum of-3 ft (0.91 ni) at the front and ends of
the enclosure. This includes trees, shrubs, and bushes.
Vegetation not in compliance with these clearance
parameters could obstruct air flow. In addition, exhaust
fumes from the generator could inhibit plant growth. See
Figure 3-2 and the accompanying descriptions.
Generator Maintenance
Regular maintenance is crucial for minimizing exhaust
emissions and reducing the risk of fire or equipment
failure. For example:
A dirty air filter or low engine oil level may cause
engine to overheat.
o Incorrect spark plug gaps may cause engine back-
firing and incomplete combustion.
IMPORTANT NOTE: See Maintenance section of
generator owner's manual to view a table of
scheduled maintenance tasks and procedures.
Perform all maintenance tasks as directed.
16 Installation Guidelines for 66 Hz Air-Cnnled r;aneratnm
Fresh Air for Ventilation and Cooling
Install 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 at a safe distance to protect the unit.
Water ingress Avoidance
• Select a,location on high ground.where water lev-
els will not rise and flood the generator. This unit
should not operate in, or be subjected to, standing
water.
o Install unit where rain gutter downspouts, roof run-
off, landscape irrigation, water sprinklers, or sump
pump discharge does not flood unit or spray enclo-
sure, including any air inlet or outlet openings.
• Excess moisture can cause excess corrosion and
decrease life expectancy of the unit.
Proximity to Utilities
• Contact local utility providers and verify proposed
site selection meets all required utility placement
requirements before installation. This could affect
warranty coverage.
o Remember, laws and or codes may regulate dis-
tance and location of unit to specific utilities.
• It is recommended to pick a location where the
generator is as close as possible to the transfer
switch and the fuel supply, while verifying the site
location conforms to the rest of the Site Selection
section.
Verify WI-Fi Range
See WI-Fi manual shipped with the unit if planning to use
the WI-Fi feature.
Transportation Recommendations
Use a suitable cart or equipment to carry generator,
including wooden pallet, to Installation site. Place
cardboard between cart and generator to prevent any
damage or scratches to generator.
Do not lift, carry, or move generator by grasping the
louvers. Doing so may bend,or damage the sheet
metal.
Site Selection and Preparation
Suitahie Mounting Surface
See Figure 3-4. Prepare a rectangular area
approximately 5 in (127 mm) deep (A) and approximately
3 in (76.2' mm) longer and wider (B) than the generator
on all sides.

Figure 3-4. Compacted Gravel or Concrete Pad
Select base type as desired or as required by local laws
or codes. The generator is typically placed on pea gravel,
crushed stone, or a concrete pad. Follow all applicable
codes if a concrete pad is required.
Verify surface where generator will be mounted is
compacted, leveled, and will not erode over time.
Generator must be level within 0.5 in (13 mm) all around.
Placement on Roofs, Platforms,. and
Other Supporting Structures
Where required to place generator on a roof, platform,
deck, or other supporting structure, generator must be
placed in accordance with the requirements in NFPA 37,
Section 4.1.3. Generator can be located 18 in (457 mm)
from structures having combustible walls and 5 ft (1.52
m) from any operable opening in the structure. Surface
beneath the generator and beyond must be
noncombustible to a minimum distance of 12 in (30.5
cm). Contact local Building Inspection Department or fire
department to determine which noncombustible materials
are approved for installation.
