Site Selection and Preparation
Installation Guidelines For 60 Hz EcoGen™ Generators 15
Fire Prevention
The generator must be installed at a safe distance away
from combustible materials. Engine, alternator, and
exhaust system components become very hot during
operation. Fire risk increases if unit is not correctly venti-
lated, is not correctly maintained, operates too close to
combustible materials, or if fuel leaks exist. Also, accu-
mulations of flammable debris within or outside the gen-
erator enclosure may ignite.
Distance Requirements
See Figure 3-2. Minimum clearances must be main-
tained around the generator enclosure. These clear-
ances are primarily for fire prevention, but also to provide
sufficient room for removing front and end panels for
maintenance purposes.
Figure 3-2. Generator Distance Requirements
ID Description Definition
A
Front and end
clearance
Minimum clearance from the front and ends of generator must be 3 ft (0.91 m). This includes

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.

Removable fence panels for servicing cannot be placed less than 3 ft (0.91 m) in front of the
generator.
F Overhead clearance 5 ft (1.52 m) minimum distance from any structure, overhang, or projections from wall.
