from combustible walls and building openings. Verify the
generator location with the local AHJ for code
compliance before positioning the generator.
General Location Guidelines
Consider the following:
•See NFPA 37, Section 4.1.3 for rooftop or platform
installations.
•See NFPA 30 for fuel storage tank requirements.
•The supporting structure must be adequate for the
generator set and its accessories.
•Confirm that the site is clean, dry, not subject to
flooding, and provided with adequate drainage in
the event of heavy rains.
•Confirm that the location permits noise and
vibration to be effectively isolated.
•Verify that the site provides easy access to the
generator set for maintenance, repair, and
firefighting purposes.
•Keep a minimum of five feet (1.5 m) of clearance
around each side of the generator set to facilitate
service or maintenance.
•Confirm that the location permits engine exhaust
gases to be safely evacuated from inhabited or
occupied areas. Consider the direction of
prevailing winds to prevent exhaust gases from
being carried back to the engine area or to the
fresh air intake vents of nearby buildings.
•The site must allow for the provision of an
adequate fuel supply. Consider the ease of
accessibility for refueling purposes.
•Verify that the location permits sufficient air flow for
cooling and ventilation. Consider the proximity of
any walls, fences, or other noise abatement or
security barriers. Do NOT face the radiator
discharge end of the enclosure into the prevailing
wind.
•Consider cold weather kit options and accessories
for the generator in cold weather locations.
•Confirm that the unit is securely fastened to the
mounting pad to prevent movement caused by
vibration.
•Verify that all electrical connections have flexible
sections to isolate vibration.
NOTE: Failure to comply with the location guidelines
can result in damage to the generator or surrounding
area and may cause the warranty to be suspended or
voided. Extra repair labor or equipment may not be
covered under the warranty if service access is
difficult or restricted.
Weather Considerations

Site Selection and Preparation
Installation Guidelines for Protector Diesel Generators 13
Section 3: Site Selection and Preparation
Site Selection
The generator must be installed outdoors in a location
that allows sufficient clearance around all sides for
reasons of safety, maintenance, and servicing.
The placement requirements for a diesel storage tank
vary by municipality. Consult with your local building code
department and fire marshal for code compliance before
selecting a location for the generator. Refer to NFPA 37
and NFPA 30 for additional requirements for the
placement of a diesel storage tank. See Installation
Checklists for additional details.
NOTE: Local codes may be different and more restrictive
than what is described here. Consult the local AHJ to
determine which standards and codes apply in your area.
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 diesel generator must
comply strictly with NFPA 30, 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. It 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 codes that are in
place in your country or local jurisdiction for
minimum distances from other structures.
•Clearance from the ends and front of the generator
must meet the requirements of NFPA 30, NFPA 37,
and all additional local code requirements
•Clearances under a deck or structure must meet
the requirements of NFPA 30, NFPA 37, and all
additional local code requirements
•Install the unit where rain gutter downspouts, 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.
•In the absence of local codes regarding placement
or clearance, we recommend following the
guidelines in this section.
•Install the generator as close as possible to the
transfer switch. REMEMBER THAT LAWS OR
CODES MAY REGULATE THE DISTANCE AND
LOCATION.
•The generator must be installed on a level surface.
The generator must be level within a 0.5 in (13
mm) all around.
Installation Guidelines for Stationary Fuel
Storage Tanks
National Fire Protection Association standard NFPA 30
indicates spacing requirements of a stationary fuel
storage tank with a mounted, enclosed generator set
from a structure, wall, or property line. Verify all spacing
requirements are correct with the assistance of local
code officials prior to finalizing genset location.
If the generator is not set to the OFF mode, it can crank
and start as soon as the battery cables are connected. If
the utility power supply is not turned off, sparking can
occur at the battery posts and cause an explosion.
Asphyxiation. Running engines produce
carbon monoxide, a colorless, odorless,
poisonous gas. Carbon monoxide, if not
avoided, will result in death or serious injury.
(000103)
DANGER
Automatic start-up. Disconnect utility power and
render unit inoperable before working on unit.
Failure to do so will result in death or serious injury.

Site Selection and Preparation
14 Installation Guidelines for Protector Diesel Generators
Site Preparation
Generator Foundation
Install the generator set on a concrete pad or base slab
able to support its weight and accessories. All applicable
codes should be followed. A proper foundation is needed
to resist dynamic loading and reduce transmitted noise
and vibration. The exact composition of the mounting pad
must follow standard engineering practices for the
required loading and application. Securely fasten the
generator set to the foundation using suitable grade,
size and style fasteners. Holes are provided in the base
frame for this purpose.
Concrete Pad
Follow all federal, state, and local codes when designing
a concrete pad or base slab.
Seat the concrete pad on a prepared solid subsurface
and use appropriate reinforcing bar or expanded wire
mesh. A common specification calls for 2500 psi (17.24
MPa) concrete reinforced with 8 gauge wire mesh.
Dimensions
Extend the concrete pad beyond the frame of the unit at
least six (6) inches (15.2 cm). This provides space for
maintenance and repair.
The base pad must be:
•Capable of supporting 125% of the unit wet weight
for single unit applications.
•Flat and level to within 1/2 inch (13 mm).
•Capable of withstanding severe torque reactions.
To calculate the depth of the concrete pad, the following
formula may be used:
W= Total wet weight of generator set in pounds (kg)
Density = Density of the concrete:
•150 pounds per cubic foot
•2400 kilograms per cubic meter
B = Foundation width in feet (meters)
L = Foundation length in feet (meters)
Suggested mixture of concrete (by volume) is 1:2:3 of
cement, sand, and aggregate with a maximum four inch
(100 mm) slump with a 28 day compression strength of
3000 psi (20.7 MPa).
Unit Clearance
Verify that the site provides easy access to the generator
set for maintenance, repair, and firefighting purposes.
Keep a minimum of 5 feet (1.5 m) of clearance around
each side of the generator set to facilitate service or
maintenance.
Stub-Up Area
For load conduit, auxiliary power conduit (high voltage),
and control wiring conduit (low voltage), see the unit
installation drawings for the location and dimensions of
the stub-up area. Figure 3-1 (A) illustrates a typical stub
opening.

Mounting
Fixed Foundation
Use mounting holes in the base frame to fasten the unit
to the foundation. Always use hardware of a suitable
grade, size and style.
Connections
All electrical connections must have flexible sections to
isolate vibration if they connect to the unit base rails.
Properly support and secure all piping before installing
the flexible connection.
Combustible Floor and Roof Protection
Engines, and their weatherproof housings, if provided,
that are installed on roofs of structures shall be located at
least 5 feet (1.5 m) from openings in walls and at least 5
feet (1.5 m) from structures having combustible walls.
Per NEC 110.26(E)(2), a minimum separation of 3 ft (0.91
m) is permitted if the adjacent wall of the structure has a
fire resistance rating of at least 1 hour.
An oil containment system consisting of a curb or dike
having a capacity at least equal to the total capacity of
the lubricating oil system or the liquid fuel system,
whichever is greater, shall be provided. This system shall
also comply with applicable requirements of NFPA 37,
Chapter 6.
The surface beneath the engine and beyond the engine
and the oil containment dike shall be noncombustible to a
minimum distance of 12 in. (300 mm).
NOTE: Local building codes may have additional
requirements for the placement of fuel storage tanks on
top of a roof or structure. Consult the local building code
department or fire marshal for code compliance before
placing the generator on top of the roof or structure.
