Distance Requirements - Generac Power Systems EcoGen 15kW Installation Manuallines

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.

Figure 3-2. Generator Distance Requirements
Minimum clearance from the front and ends of generator must be 3 ft (0.91 m). This includes
shrubs, bushes, and trees.
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.
No operable windows, doors, vents, window wells, or openings in the wall are permitted near any
point of the generator. See
The generator should not be placed closer than 18 in (457 mm) from existing walls.
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.
5 ft (1.52 m) minimum distance from any structure, overhang, or projections from wall.
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.

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.
