Figure 3-1. Installation Guidelines
These guidelines are based upon fire
testing of the generator enclosure and
the manufacturer’s requirement for air
flow for proper operation. Local codes
may be different and more restrictive
than what is described here.
Clearance from the ends and front of the gener-
ator must be 36 in (914 mm). This would
include shrubs, bushes or trees. Clearance at
the top should be a minimum of 60 in (1524
mm) from any structure, overhang or projec-
tions from the wall. The generator should not
be placed under a deck or other structure that
is closed in and would limit or constrain air flow.
No operable windows or openings in the wall permitted
within 5 ft (1.52 m) from any point of the generator.
Clearance from operable
windows, doors or any
openings in the wall.
