Installation Guidelines For 60 Hz EcoGen™ Generators 13
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
(C). 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 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 3-1 and the installation drawing
within the owner’s manual for details.
NOTE: If the generator is not set to OFF, it can crank and
start as soon as the battery cables are connected.
Sparking can occur at the battery posts and cause an
explosion.
Site Preparation
• Locate the mounting area as close as possible to
the connected loads 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. Verify that
exhaust fumes will not enter any building through
eaves, windows, ventilation fans, or other air
intakes (see Site Selection).
• Select the type of base, such as—but not limited
to—compacted soil, gravel, or concrete, as desired
or as required by local laws or codes. Verify your
local requirements before selecting.
Material Sufficient for Level Installation
•
Prepare a rectangular area approximately 5 in (127
mm) deep (A) and approximately 6 in (152 mm)
longer and wider (B) than the footprint of the
generator. Verify that the surface where the
generator will be mounted is compacted, leveled,
and will not erode over time. A concrete pad can be
poured if desired or required.
Figure 3-3. Compacted Soil or Gravel Pad
NOTE: If a concrete pad is required, follow all applicable
federal, state, or local codes.
Accidental start-up. Disconnect power and render
unit inoperable before performing service work.
Failure to do so will result in death or serious injury.
Asphyxiation. Running engines produce
carbon monoxide, a colorless, odorless,
poisonous gas. Carbon monoxide, if not
avoided, will result in death or serious injury.
