Section 1: Safety Rules & General Information
Introduction
Thank you for purchasing this compact, high-
performance, variable speed, air-cooled, engine-driven
stationary automatic standby generator set. Every effort
has been made to ensure that the information and
instructions in this manual are both accurate and
complete at the time of release. However, the
manufacturer reserves the right to change, alter, or
otherwise improve this product at any time without prior
notice.
In off–grid applications as a part of an alternative energy
system, the generator starts when the inverter/battery
charger detects the normal power source voltage has
dropped below a preset level. The generator powers the
inverter and, once the voltage level of the battery rises to
an acceptable level, the generator is shut down. Another
off–grid application would be for use in remote locations
such as for pumping water for a village or campground,
or for livestock.
The unit is factory installed in an all–weather metal
enclosure and is intended for outdoor installation
only. The generator can be operated using either natural
gas (NG) or vapor withdrawn liquid propane (LP).
NOTE: When properly sized, this generator is suitable
for supplying typical residential loads such as induction
motors (sump pumps, refrigerators, air conditioners,
furnaces, etc.), electronic components (computer,
monitor, TV, etc.), lighting loads and microwaves, or
loads less than 10 kW or 2 hp.

the top should be a minimum of 5 ft (1.52 m) from
any structure, overhang or projections from the wall.
•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 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.
•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
LOCATION.
•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,
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.
Installation Guidelines for Stationary Air–Cooled
Generators
See Figure 3-1. The National Fire Protection Association
has a standard for the installation and use of stationary
combustion engines. That standard is NFPA 37; 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,
that are 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
noncombustible materials and it has been
demonstrated 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 that are frequently
available for installation, it has become apparent that
exception (2) would be beneficial for many residential
and commercial installations. With that in mind, the
manufacturer contracted with an independent testing
laboratory to run full scale fire tests to assure that the
enclosure will not ignite combustible materials outside
the enclosure.
NOTE: Southwest Research Institute testing
approves 18 in (457 mm) installation minimum from
structure. Southwest Research is a nationally
recognized third party testing and listing agency.
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.
Figure 3-2. Southwest Research Institute Decal
The Southwest Research Institute Decal is located inside
the generator, next to the generator’s data decal.
http://www.swri.org/4org/d01/fire/listlab/listprod/director.htm
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.

Site Selection and Preparation
Installation Guidelines for 60 Hz EcoGen™ Generator 13
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 m) at the front and ends of
the enclosure. This would include 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 3-1 and the installation drawing
within the Owner’s Manual for details.
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.
Site Preparation
•Locate the mounting area as close as possible to the
transfer switch and fuel supply.
•Leave adequate room around the area for service
access (check local code), and place high enough to
keep rising water from reaching the generator.
•Choose an open space that will provide adequate
and unobstructed airflow.
•Place the unit so air vents won’t become clogged
with leaves, grass, snow or debris. Make sure
exhaust fumes will not enter the building through
eaves, windows, ventilation fans or other air intakes
(see Site Selection).
•Select the type of base, such as but not limited to
gravel or concrete, as desired or as required by local
laws or codes. Verify your local requirements before
selecting.
Material Sufficient for Level Installation
•See Figure 3-3. Dig a rectangular area
approximately 5 in (127 mm) deep [A] and about 6 in
(152 mm) longer and wider [B] than the footprint of
the generator. Fill with 4 in (102 mm) of pea gravel
[C], crushed stone or any other non–combustible
material sufficient for level installation. Compact and
level the material. A concrete pad can be poured if
desired or required. The pad should be 4–5 in (102–
127 mm) thick and extend 6 in (152 mm) beyond the
outside of the generator in all directions.
Figure 3-3. Compacted Gravel Pad
NOTE: If a concrete pad is required, follow all applicable
federal, state or local codes.
Figure 3-4. Poured or Pre–formed Concrete Pad
Transportation Recommendations
Use a two wheeled hand cart or metal rails to carry the
generator (including the wooden pallet) to the installation
site. Place cardboard between the hand cart and the
generator to prevent any damage or scratches to the
generator.
Automatic start-up. Disconnect normal power source
and render unit inoperable before working on unit.
Failure to do so will result in death or serious injury.
(000236)
DANGER
Asphyxiation. Running engines produce
carbon monoxide, a colorless, odorless,
poisonous gas. Carbon monoxide, if not
avoided, will result in death or serious injury.

Installation Guidelines for 60 Hz EcoGen™ Generator 15
Section 4: Generator Placement
Generator Placement
See Figure 4-1. All air–cooled generators come with a
composite pad. The composite pad elevates the
generator and helps prevent water from pooling around
the bottom of the generator. The generator and
composite pad can be placed on 4 in (102 mm) of pea
gravel that is compacted, or on a concrete pad. Check
local codes to see what type of site base is required. If a
concrete pad is required, all federal, state and local
codes should be followed. Place the generator on its
mounting pad and position correctly as per the
dimensional information given in Site Selection and
Preparation.
NOTE: Generator must be level within 0.5 in (13 mm).
NOTE: If the composite pad is removed for concrete
mounting, the fascia kit will not fit.
Figure 4-1. Composite Pad
See Figure 4-2. Four mounting points are provided for
securing the generator to concrete—two holes at the
inside front of the enclosure and two outside rear
mounting brackets.
NOTE: Use the template at the top of the generator
carton to mark the concrete pad for drilling of the two
front mounting holes. For dimensions of the two rear
mounting holes, see Installation Drawing (2 of 2). DO
NOT USE brackets from shipping pallet. Use stainless
steel brackets provided with loose parts.
Figure 4-2. Mounting Hole Location
Fascia Installation (If Applicable)
•Locate the four (4) threaded black rubber bumpers
located in the Owner’s Manual bag.
•See Figure 4-3. Remove the four (4) bumpers from
the bag and screw them into threaded holes located
inside the end pieces of the fascia (two each)
opposite one another (A).
•Once the bumpers are installed, snap one of the end
pieces into one of the front / rear pieces of fascia.
Repeat this action with the other two remaining
pieces of fascia.
NOTE: Do not assemble all four pieces together at this
point (B).
•Place both assemblies at the base of the generator
and fit the rubber bumpers into the lifting holes in the
generator base (C).
•Once aligned, snap together the two remaining
connection points.
