Auxiliary Shutdown Switch
All generators are equipped with an external
means of shutting down the generator which
complies with the latest NEC code require-
ment. The primary generator shutdown
sequence is described in Control Panel
Startup / Testing.
See Figure 2-11. An auxiliary shutdown switch
(A) is located on the exterior of the generator
back panel. This switch shuts down the gener-
ator and disables restarts.
Figure 2-11. Auxiliary Shutdown Switch
(all models)
NOTE: Whenever possible, perform primary
shutdown procedure before disabling genera-
tor with auxiliary shutdown switch.
See Figure 2-12. 14–26 kW generators have
an auxiliary shutdown switch (B) located
inside the generator.
Figure 2-12. Auxiliary Shutdown Switch
(14–26 kW)
NOTE: Generator will not start if either switch
is OPEN (O). Controller displays an “Auxiliary
Shutdown” alarm, and red LED “Alarm” light
illuminates until switch or switches are
CLOSED (I) and alarm is cleared by pressing
OFF mode button, and then ENTER. Once
cleared, generator can be placed back in
AUTO or MANUAL.
Equipment Damage. The auxiliary shutdown switch
is not to be used to power down the unit under
normal operating circumstances. Doing so will
result in equipment damage.

Installation Guidelines for 60 Hz Air-Cooled Generators 13
Section 3: Site Selection and Preparation
Site Selection
Site selection is critical for safe generator
operation. It is important to discuss these fac-
tors with the installer when selecting a site for
generator installation:
•Carbon monoxide
•Fire prevention
•Fresh air for ventilation and cooling
•Water ingress prevention
•Proximity to utilities
•Suitable mounting surface
The following pages describe each of these
factors in detail.
NOTE: The term “structure” is used
throughout this section to describe the home
or building where generator is being installed.
Illustrations depict a typical residential home.
However, instructions and recommendations
presented in this section apply to all structures
regardless of type.
Carbon Monoxide
IMPORTANT NOTE: Move to fresh air
immediately and seek medical attention if
you feel sick, dizzy, or weak while the gen-
erator is running or after it stops.
Generator exhaust contains carbon monox-
ide (CO)—a poisonous, potentially lethal gas
that cannot be seen or smelled. The genera-
tor must be installed in a well ventilated area
away from windows, doors, and openings.
The selected location should not allow
exhaust gases to be drawn into structures
where people or animals may be present.
Carbon Monoxide Detectors
See Figure 3-1. CO detectors (K) must be
installed and used to monitor for CO and to
warn individuals about the presence of CO.
CO detectors must be installed and tested in
accordance with the CO detector manufac-
turer’s instructions and warnings. Contact
local building inspection department for any
applicable requirements concerning CO
detectors. See NFPA 72, National Fire Alarm
and Signaling Code, and Section R315 in the
ICC International Residential Code for more
information.
IMPORTANT NOTE: Common smoke
alarms do NOT detect CO gas. Do not rely
on smoke alarms to protect residents or
animals from CO. The only way to detect
CO is to have functioning CO alarms.
(000103)
Asphyxiation. Running engines produce carbon
monoxide, a colorless, odorless, poisonous
gas. Carbon monoxide, if not avoided, will
result in death or serious injury.
DANGER

Site Selection and Preparation
14 Installation Guidelines for 60 Hz Air-Cooled Generators
Potential CO Entry Points
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.

ID Entry Point Description / Comments
AWindows and
doors
Architectural details which can be (or are) opened to admit fresh air into the
structure.
B Garage door CO can leak into garage if door is open, or does not seal correctly when closed.
C Attic vent Attic vents, ridge vents, crawl space vents, and soffit vents can all admit generator
exhaust.
DBasement
windows Windows or hatches allowing ventilation to or from lower level of a structure.
EFurnace intake /
exhaust vent Air intake and exhaust pipes for furnace.
F Wall cracks Includes (but not limited to) cracks in wall, foundation, mortar, or air gaps around
doors, windows, and pipes. See Protect the Structure.
G Dryer vent Exhaust duct for clothes dryer.
HAirflow
restrictions
Structural features, including but not limited to: corners, alcoves, fences,
courtyards, and areas with heavy vegetation can restrict correct airflow around
unit. Exhaust gases can be collected in these areas.
JHVAC
components
Do not direct generator discharge into HVAC components, including but not
limited to: make up air systems, AC condensers, and window AC units.
IMPORTANT NOTE: Mechanical and gravity outdoor air intake openings for
HVAC supply air systems shall be located according to Section 401 in the
ICC Mechanical Code. See ICC Mechanical Code for any additional
requirements.

Site Selection and Preparation
Installation Guidelines for 60 Hz Air-Cooled Generators 15
Fire Prevention
The generator must be installed at a safe dis-
tance away from combustible materials.
Engine, alternator, and exhaust system com-
ponents become very hot during operation.
Fire risk increases if unit is not correctly ven-
tilated, is not correctly maintained, operates
too close to combustible materials, or if fuel
leaks exist. Also, accumulations of flamma-
ble 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 pre-
vention, but also to provide sufficient room
for removing front and end panels for mainte-
nance purposes.

ID Description Definition
AFront and end
clearance
Minimum clearance from the front and ends of generator must be 3 ft (0.91 m).
This includes shrubs, bushes, and trees.
B Rear clearance
Fuel and electrical connections are made here. 18 in (457 mm) minimum
clearance per SwRI testing, labeling, and listing, unless state or local codes
dictate otherwise.
CWindows, vents,
and openings
No operable windows, doors, vents, window wells, or openings in the wall are
permitted near any point of the generator. See Potential CO Entry Points for
more information.
D Existing wall The generator should not be placed closer than 18 in (457 mm) from existing
walls.
E Removable fence
A removable barrier (non-permanent; without footings) installed as a visual
surround.
Removable fence panels for servicing cannot be placed less than 3 ft (0.91 m)
in front of the generator.
FOverhead
clearance
5 ft (1.52 m) minimum distance from any structure, overhang, or projections
from wall.
GMaintenance and
servicing
Maneuvering space around generator for performing routine maintenance
tasks such as battery replacement and engine service. Do not attempt to
conceal generator with shrubs, bushes, or plants. See NEC Article 110.26 for
more information.

Site Selection and Preparation
16 Installation Guidelines for 60 Hz Air-Cooled Generators
Fire Codes, Standards, and
Guidelines
Generator installation must comply strictly
with ICC IFGC, NFPA 37, NFPA 54, NFPA
58, and NFPA 70 standards. These stan-
dards prescribe the minimum safe clear-
ances 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.
Figure 3-3. Southwest Research Institute
Marking
NOTE: The Southwest Research Institute
(SwRI) is a nationally recognized third party
testing and listing agency. SwRI testing
approves 18 in (457 mm) installation 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 instal-
lation 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. This offset reduction does not apply
to clearances from openings in the structure.
For adequate maintenance and airflow clear-
ance, the area above the generator should
be at least 5 ft (1.52 m) with a minimum of 3 ft
(0.91 m) at the front and ends of the enclo-
sure. 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 Fig-
ure 3-2 and the accompanying descriptions.
Generator Maintenance
Regular maintenance is crucial for minimiz-
ing 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.
•Incorrect spark plug gaps may cause
engine backfiring and incomplete
combustion.
IMPORTANT NOTE: See Maintenance sec-
tion of generator owner’s manual to view a
table of scheduled maintenance tasks and
procedures. Perform all maintenance tasks
as directed.
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 blow-
ing 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 levels will not rise and flood the
generator. This unit should not operate in, or
be subjected to, standing water.
•Install unit where rain gutter downspouts,
roof run-off, landscape irrigation, water
sprinklers, or sump pump discharge does
not flood unit or spray enclosure, 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.
•Remember, laws and or codes may
regulate distance 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.
